00:00:00.030 hey they don't gas to here today's video 00:00:02.18000:00:02.190 is getting all the heat exchanges back 00:00:03.80000:00:03.810 on to the Detroit Diesel and is proudly 00:00:05.42000:00:05.430 sponsored by marine engine calm all 00:00:19.13000:00:19.140 right first step in getting these heat 00:00:21.52900:00:21.539 exchangers back on is getting them 00:00:22.88000:00:22.890 cleaned up so let's start there the idea 00:00:25.18900:00:25.199 with the heat exchanger is that it works 00:00:26.59900:00:26.609 very similar to a radiator in a car 00:00:28.33000:00:28.340 except instead of cold air blowing 00:00:31.04000:00:31.050 across the radiator and cooling the 00:00:32.65900:00:32.669 coolant that's flowing through it you 00:00:34.28000:00:34.290 have another fluid flowing through it in 00:00:36.56000:00:36.570 one direction that cools a different 00:00:38.00000:00:38.010 fluid going in the other direction this 00:00:40.36900:00:40.379 is the raw water heat exchanger wall 00:00:43.13000:00:43.140 water as in sea water just comes from 00:00:44.81000:00:44.820 outside the boat comes in goes through 00:00:47.36000:00:47.370 the heat exchanger and then goes 00:00:48.88900:00:48.899 overboard again and it cools the coolant 00:00:51.86000:00:51.870 that runs through the engine itself so 00:00:53.68900:00:53.699 the engine runs on coolant like you 00:00:55.67000:00:55.680 would in your car fresh water with some 00:00:57.47000:00:57.480 glycol or whatever added and then the 00:01:00.43900:01:00.449 sea water cools that coolant so this is 00:01:02.11900:01:02.129 the equivalent of the radiator main 00:01:03.56000:01:03.570 radiator in the car then once that fresh 00:01:05.96000:01:05.970 water is cooled down by the seawater 00:01:07.58000:01:07.590 that fresh water then in turn runs 00:01:09.83000:01:09.840 through these two heat exchangers to 00:01:11.39000:01:11.400 cool the engine oil and the gearbox oil 00:01:14.21000:01:14.220 all three of them need cleaning up 00:01:15.92000:01:15.930 before I put them back in the boat you 00:01:17.69000:01:17.700 can run you know like a descaler flush 00:01:21.56000:01:21.570 through these components Institute 00:01:23.48000:01:23.490 nowhere near as easily as now while 00:01:25.64000:01:25.650 they're apart so let's do it 00:01:27.35000:01:27.360 this is the product line used for this I 00:01:29.48000:01:29.490 saw this for the first time at the boat 00:01:31.21900:01:31.229 show never used it before but it's 00:01:33.08000:01:33.090 specifically for this job one thing I 00:01:35.17900:01:35.189 particularly like about this stuff is it 00:01:36.62000:01:36.630 very very safe hopefully you can see 00:01:38.66000:01:38.670 this graph without too much glare but 00:01:40.55000:01:40.560 what it's saying here this top line is 00:01:42.62000:01:42.630 the CFS where you can leave it in for 00:01:44.66000:01:44.670 quite a long time and you lose about 00:01:46.63900:01:46.649 three percent of the metal whereas with 00:01:48.31900:01:48.329 other products you know you can get to 00:01:49.85000:01:49.860 the point where after 101 700 which of 00:01:52.21900:01:52.229 my glasses 20 hours I think it is in 00:01:54.74000:01:54.750 solution you've lost almost two percent 00:01:56.27000:01:56.280 of the mass of the metal and that's 00:01:58.37000:01:58.380 really what you don't want so we're 00:02:00.64900:02:00.659 gonna go the immersion route where we're 00:02:02.24000:02:02.250 going to get a tub we have to mix this 00:02:03.95000:02:03.960 up at a ratio of four to one one part of 00:02:06.08000:02:06.090 the descaler four parts water and then 00:02:08.60000:02:08.610 we're gonna soak them for between one 00:02:10.30900:02:10.319 and four hours just checking it 00:02:11.63000:02:11.640 regularly see how it's going 00:02:13.04000:02:13.050 this one's a bit taller than the bucket 00:02:15.11000:02:15.120 of trot so we'll probably have to sort 00:02:16.97000:02:16.980 of in friend it means the area at the 00:02:20.15000:02:20.160 interface is going to be in twice as 00:02:21.44000:02:21.450 long so it's a bit of a shame but I'll 00:02:23.72000:02:23.730 keep a close eye on it once again makes 00:02:26.12000:02:26.130 me comfortable this stuff can actually 00:02:27.29000:02:27.300 be left in for like a hundred and 00:02:29.24000:02:29.250 something hours and not eat the metal 00:02:30.77000:02:30.780 away speaking of which I have here when 00:02:34.61000:02:34.620 I first cleaned up so I have I love it 00:02:36.74000:02:36.750 this piece here is actually the front of 00:02:39.26000:02:39.270 the heat exchanger there's one inside 00:02:40.58000:02:40.590 for the water in and out and see what it 00:02:44.39000:02:44.400 comes down this way coolant comes down 00:02:46.22000:02:46.230 this way 00:02:46.79000:02:46.800 what I do is I've actually had this 00:02:48.98000:02:48.990 soaking in a solvent to get the paint 00:02:50.87000:02:50.880 off this was painted initially I'm also 00:02:52.76000:02:52.770 going to put this in as well and just 00:02:54.26000:02:54.270 see how it goes see if it cleans it up a 00:02:55.85000:02:55.860 little bit more because these components 00:02:59.75000:02:59.760 I'm actually not going to repaint I 00:03:02.06000:03:02.070 figure they're nice brass components or 00:03:03.86000:03:03.870 bronze check and you know why not have 00:03:08.15000:03:08.160 them look that way when you're cleaning 00:03:09.92000:03:09.930 a heat exchanger like this I would go 00:03:11.66000:03:11.670 for a bit of a mechanical clean first 00:03:13.40000:03:13.410 give it a brush blow some compressed air 00:03:15.65000:03:15.660 through it just get as much of the gunk 00:03:16.97000:03:16.980 out as you can first then we'll give it 00:03:18.77000:03:18.780 a soak this heat exchanger actually 00:03:21.23000:03:21.240 blasted with a pressure washer through 00:03:22.69900:03:22.709 to get most of the gunk out first you 00:03:25.19000:03:25.200 need to be careful with different metals 00:03:26.77000:03:26.780 the instructions for the CFS give you 00:03:29.63000:03:29.640 different ratios depending on what type 00:03:31.16000:03:31.170 of metal it is and what type of metals 00:03:32.84000:03:32.850 it's not in any way compatible with good 00:03:35.69000:03:35.700 example of that is this this is the oil 00:03:39.08000:03:39.090 filter fuel filter housing off the boat 00:03:41.99000:03:42.000 I threw a whole lot of stuff into some 00:03:45.04000:03:45.050 what was it soda ash on these sort of 00:03:47.81000:03:47.820 paint stripper type stuff everything 00:03:50.06000:03:50.070 that was steel was fine but the 00:03:51.35000:03:51.360 aluminium got eaten away really badly so 00:03:53.18000:03:53.190 be careful when you deal with aluminium 00:03:54.80000:03:54.810 in particular all right I'm gonna go 00:03:58.01000:03:58.020 fill this container with waters a 2 00:03:59.66000:03:59.670 litre container until the buckets 00:04:01.46000:04:01.470 getting reasonably full and then we're 00:04:03.59000:04:03.600 going to add a fifth of this solution 00:04:06.47000:04:06.480 which is one to four so it's tier one 00:04:08.44900:04:08.459 part solution four parts this so 20 00:04:10.55000:04:10.560 percent another point of gasses just 00:04:12.68000:04:12.690 don't be confused by the ratio 2 00:04:14.27000:04:14.280 percentage it's because it's one to four 00:04:17.27000:04:17.280 it's not a quarter this stuff it's 00:04:18.92000:04:18.930 actually 20 percent because it's one 00:04:21.20000:04:21.210 part CFS four parts water 00:04:24.51000:04:24.520 [Music] 00:04:31.44000:04:31.450 [Applause] 00:04:34.76900:04:34.779 alright that's 8 liters of water put in 00:04:37.65900:04:37.669 2 litres of CFS leaves me a little bit 00:04:40.02900:04:40.039 of room for the displacement that the 00:04:41.55900:04:41.569 objects all cause 00:04:45.46000:04:45.47000:04:49.42000:04:49.430 it's quite thick and heaviest stuff it 00:04:52.07000:04:52.080 has quite a high specific gravity so 00:04:53.92900:04:53.939 this 5 litres weighs well over 5 kilos 00:04:58.75000:04:58.76000:05:04.14900:05:04.159 this stuff's also biodegradable which 00:05:06.43900:05:06.449 makes it nice when it comes to disposal 00:05:09.27900:05:09.289 it's nothing too nasty to get rid of so 00:05:15.70900:05:15.719 let's try this one first it's got a bit 00:05:19.33900:05:19.349 of bit of gasket on the back edge still 00:05:26.38900:05:26.399 so get rid of that 00:05:27.12000:05:27.13000:05:31.08900:05:31.099 ok part one that's what it looks like 00:05:33.79900:05:33.809 hang and I'll bring you over the pipe so 00:05:38.29900:05:38.309 this is what the part looks like now 00:05:43.23900:05:43.249 this is what it looks like before 00:05:45.04900:05:45.059 anything goes in it see there we go 00:05:54.45900:05:54.469 alright we'll leave that to soak and 00:05:56.77900:05:56.789 I'll check it each hour can already see 00:05:59.44900:05:59.459 some debris coming up to the surface of 00:06:01.36900:06:01.379 the water shall I turn it around a few 00:06:08.32900:06:08.339 times just get any trapped air out of it 00:06:14.07900:06:14.089 which means we're getting to the inside 00:06:16.39900:06:16.409 of it - all right getting better each 00:06:21.58900:06:21.599 time we're definitely getting still a 00:06:23.42000:06:23.430 bit of air coming out though each time I 00:06:24.67900:06:24.689 rotate it alright we'll leave it like 00:06:27.79900:06:27.809 that 00:06:28.21900:06:28.229 give it an hour alright it's been 1 hour 00:06:31.27900:06:31.289 now let's take it out and have a look 00:06:33.49900:06:33.509 where we're at 00:06:45.89900:06:45.909 certainly looks a lot cleaner this is 00:06:48.99900:06:49.009 between one and four I reckon I'm gonna 00:06:50.76900:06:50.779 give it one more hour two hours then 00:06:52.98900:06:52.999 we'll just give it a little bit of a 00:06:54.12900:06:54.139 light brush maybe maybe a bit of a light 00:06:58.05900:06:58.069 brush before we put it back in this is 00:06:59.73900:06:59.749 just a nylon bristle brush so nothing 00:07:02.64900:07:02.659 too serious probably makes sense to get 00:07:08.49900:07:08.509 some of this stuff that's now loose off 00:07:11.97900:07:11.989 before it goes back in all right let's 00:07:23.19900:07:23.209 give it another out a little bit short 00:07:25.86900:07:25.879 of two hours now but let's take it out 00:07:27.63900:07:27.649 and have a look so you've got a head off 00:07:35.18900:07:35.199 yeah definitely a bit cleaner again all 00:07:38.52900:07:38.539 right I'm gonna give this a really good 00:07:40.17900:07:40.189 rinse with fresh to get the solution off 00:07:42.51900:07:42.529 it and then I'll pop the other one in 00:07:44.64900:07:44.659 for a couple of hours as well all right 00:07:46.73900:07:46.749 here's the second of the oil heat 00:07:49.29900:07:49.309 exchangers it's much much cleaner we'll 00:07:54.42900:07:54.439 take this one over to and I'll stick it 00:07:59.07900:07:59.089 on the tap and just show you 00:08:03.83000:08:03.84000:08:07.42000:08:07.430 you sort of run some water through then 00:08:11.33000:08:11.340 I was finding it was a bit chunky on the 00:08:13.46000:08:13.470 other one till it run through for a 00:08:15.89000:08:15.900 while but it gave it a good internal 00:08:18.08000:08:18.090 flush okay this one's kind of the worst 00:08:28.96900:08:28.979 because it's the one that the saltwater 00:08:30.59000:08:30.600 runs through this has salt water cooling 00:08:33.05000:08:33.060 fresh water whereas these ones were 00:08:35.06000:08:35.070 fresh water cooling oil all right this 00:08:39.14000:08:39.150 is what it looks like at the moment so 00:08:40.31000:08:40.320 let's dump it in that in first and see 00:08:42.32000:08:42.330 what looks like in a couple of hours to 00:08:44.63000:08:44.640 be honest with you I don't think we're 00:08:46.01000:08:46.020 gonna have a huge amount of overlap 00:08:48.57900:08:48.589 certainly fizzing away I think by the 00:08:52.40000:08:52.410 time we infer end it that's about the 00:08:55.22000:08:55.230 depth of the water we've got so a couple 00:08:57.98000:08:57.990 hours one way a couple hours the other 00:08:59.87000:08:59.880 way this is what the top half looks like 00:09:02.30000:09:02.310 before it's gone in so we'll just flip 00:09:04.19000:09:04.200 it in friend now this hasn't been in 00:09:06.50000:09:06.510 long actually probably only about 45 00:09:08.66000:09:08.670 minutes maybe close to an hour but I 00:09:10.76000:09:10.770 just want to keep it rotating rather 00:09:12.23000:09:12.240 having it sit for the full two hours on 00:09:13.82000:09:13.830 one side then flipping it over 00:09:27.00000:09:27.010 just topping it up with a bit more CFS 00:09:30.07000:09:30.080 and water just so that the fluid level 00:09:31.96000:09:31.970 reaches past halfway where it was before 00:09:34.53000:09:34.540 otherwise it would have had a little gap 00:09:36.49000:09:36.500 in the middle that wouldn't have been 00:09:39.31000:09:39.320 done this is what the top looks like now 00:09:44.43000:09:44.440 give it a good rinse when it's finished 00:09:47.57900:09:47.589 actually now that that's out of the 00:09:50.29000:09:50.300 water 00:09:50.91000:09:50.920 maybe I should have actually rinsed that 00:09:52.99000:09:53.000 then put it in the other way around 00:09:54.60000:09:54.610 otherwise this does have the solution 00:09:57.97000:09:57.980 sitting on the surface of it let's do 00:09:59.32000:09:59.330 that give it a good rinse then I'll put 00:10:00.67000:10:00.680 it back in this way I'll flip it again 00:10:03.19000:10:03.200 hasn't been in long it's obviously not 00:10:04.78000:10:04.790 finished but it's doing a good job 00:10:07.56000:10:07.570 somewhere down in this primordial ooze 00:10:12.21000:10:12.220 yeah he's a puller it was really crusty 00:10:17.89000:10:17.900 and rusty I've actually left in there 00:10:24.37000:10:24.380 overnight 00:10:29.40000:10:29.410 morning chickens 00:10:30.99000:10:31.00000:10:40.72000:10:40.730 speaking of chickens this is definitely 00:10:44.81000:10:44.820 my injured chicken yes and I Daffy's a 00:10:46.70000:10:46.710 duck named kids named her you're in the 00:10:51.44000:10:51.450 infirmary aren't you yes all right Julie 00:10:56.30000:10:56.310 here we go 00:10:57.29000:10:57.300 breakfast that eats generally a pretty 00:11:00.74000:11:00.750 chilled chicken just done it apart while 00:11:02.54000:11:02.550 she's eating I'm gonna do this end of 00:11:18.08000:11:18.090 the main heat exchanger again I'll clean 00:11:20.18000:11:20.190 this up with a brush as well as been a 00:11:22.10000:11:22.110 bit of mud really but I'm actually this 00:11:24.80000:11:24.810 is looking pretty monkey now so I think 00:11:26.39000:11:26.400 I'll put a fresh load of the CFS in and 00:11:28.82000:11:28.830 then do the other end again but I will I 00:11:31.61000:11:31.620 should just give this a brush up with a 00:11:32.75000:11:32.760 wire brush see what it looks like 00:11:42.89000:11:42.90000:11:50.23000:11:50.240 looking like it's still got some life 00:11:52.01000:11:52.020 left in it I wish I had a helmet before 00:11:55.46000:11:55.470 I popped it in camera is flat I didn't 00:11:58.49000:11:58.500 really think to go and get my phone but 00:12:01.15000:12:01.160 looking he was better than it was after 00:12:03.89000:12:03.900 that slime it's quite nice to see a 00:12:05.57000:12:05.580 fresh batch it's interesting it starts 00:12:07.94000:12:07.950 out this color as soon as you pour in 00:12:11.36000:12:11.370 the water so there goes green let's take 00:12:17.24000:12:17.250 this end of the heat exchange just a 00:12:19.70000:12:19.710 little bit longer maybe another 30 00:12:22.43000:12:22.440 minutes while I'm here 00:12:28.42000:12:28.430 who might try these heat exchanger caps 00:12:31.25000:12:31.260 to see if it makes any difference to 00:12:34.40000:12:34.410 those alright I'll just add a little bit 00:12:42.38000:12:42.390 more water to cover them alright all 00:12:45.80000:12:45.810 covered over now let that soak for a 00:12:47.21000:12:47.220 little while alright here are my three 00:12:49.28000:12:49.290 heat exchanger cause I've dropped the 00:12:51.23000:12:51.240 gasket onto this one I'm just gonna find 00:12:53.75000:12:53.760 the gaskets for these two and just start 00:12:55.73000:12:55.740 piecing them together oh yeah here's one 00:12:57.92000:12:57.930 I think these actually have the same 00:13:02.50000:13:02.510 shape and bolt pattern so that's fine I 00:13:05.50000:13:05.510 thought I did have two of these but I 00:13:08.45000:13:08.460 think maybe I'm thinking of these but I 00:13:10.73000:13:10.740 had three of the square ones how well 00:13:15.37000:13:15.380 I'll see how quick it is to order it 00:13:17.93000:13:17.940 otherwise I'll just make one this plate 00:13:20.24000:13:20.250 here goes over the end I left AB look at 00:13:23.57000:13:23.580 my video sphere which way over the end 00:13:26.72000:13:26.730 of the heat exchanger core which is the 00:13:29.54000:13:29.550 main saltwater heat exchanger this is 00:13:32.00000:13:32.010 the one that pulls the coolant the 00:13:33.56000:13:33.570 coolant calls the other two this has an 00:13:36.98000:13:36.990 o-ring in here which is pretty squished 00:13:40.25000:13:40.260 and this so ring seals around the 00:13:45.71000:13:45.720 outside are here so I'll find a 00:13:47.87000:13:47.880 screwdriver or a pic or something and 00:13:49.66000:13:49.670 get this old one out and put the new one 00:13:52.73000:13:52.740 in with a bit of grease on it 00:13:59.59000:13:59.600 I will clean this out brush all this 00:14:08.20000:14:08.210 gunk out and then see if we can get this 00:14:11.05000:14:11.060 in I'm actually tempted to take this 00:14:16.63000:14:16.640 home and give it a soak and then repaint 00:14:18.61000:14:18.620 it it's great having the workshop to do 00:14:25.30000:14:25.310 this job in big thanks to Dean for that 00:14:28.06000:14:28.070 but it's just means things are spread 00:14:32.92000:14:32.930 across a couple locations again you know 00:14:35.89000:14:35.900 I think I'm going to do that you know 00:14:37.00000:14:37.010 take this home clean it paint it again 00:14:39.31000:14:39.320 fit the o-ring bring it back it's no big 00:14:42.13000:14:42.140 deal all right what I'm going to do now 00:14:44.20000:14:44.210 is I have covered oil gallery just 00:14:48.04000:14:48.050 connects I'll show it to you hang on 00:14:49.81000:14:49.820 let's get some gloves done wash solvent 00:14:53.56000:14:53.570 at the moment just getting small paint 00:14:55.33000:14:55.340 and stuff on clean the old paint off put 00:14:59.83000:14:59.840 it on the wire wheel and I've got to 00:15:02.05000:15:02.060 make a couple of gaskets for it this 00:15:04.60000:15:04.610 part feeds the oil lines that go to a D 00:15:06.97000:15:06.980 box I believe it's a part of the engines 00:15:09.37000:15:09.380 paralyzation so it's not that easy to 00:15:12.13000:15:12.140 find the factory gaskets from a Detroit 00:15:14.08000:15:14.090 you know past specialist so this is what 00:15:17.20000:15:17.210 the solvents done to this paint 00:15:18.55000:15:18.560 overnight should be able to wipe the 00:15:21.64000:15:21.650 bulk of it off but we'll brush the rest 00:15:27.42000:15:27.43000:15:30.57900:15:30.589 I'll pop it on the wire wheel to clean 00:15:33.11000:15:33.120 up these mating surfaces then we'll make 00:15:34.76000:15:34.770 the gasket alright this is the only drag 00:15:42.44000:15:42.450 of gasket paper I could find in the 00:15:44.09000:15:44.100 workshop but left to do try somebody 00:15:47.36000:15:47.370 spray grease I can't find anything below 00:15:52.28000:15:52.290 it between the workshop the boat moan 00:15:59.84000:15:59.850 moan moan alright yeah this stuff goes 00:16:04.05000:16:04.06000:16:09.43000:16:09.440 pretty bad mm not too bad actually 00:16:14.47000:16:14.480 alright I think I can actually work with 00:16:16.40000:16:16.410 that we can always test it so punch this 00:16:25.51000:16:25.520 for those middle hot pretty close 00:16:30.41000:16:30.420 actually 00:16:31.00000:16:31.010 alright we might be in luck it's not bad 00:16:45.59000:16:45.600 either puncture holes before you cut 00:16:47.75000:16:47.760 them out cuz stops the edge distorting 00:16:53.55000:16:53.56000:17:01.48000:17:01.490 and I think this one no it's ah this one 00:17:06.61000:17:06.620 was actually pretty close just having a 00:17:22.22000:17:22.230 look at the real thing quickly to get a 00:17:25.49000:17:25.500 sense of how the lines actually go there 00:17:40.25000:17:40.260 let's have a look whether we've missed 00:17:42.26000:17:42.270 the mark entirely or whether it seems 00:17:44.35000:17:44.360 usable put it on the right one right 00:17:47.12000:17:47.130 yeah that'll do okay 00:17:51.20000:17:51.210 one different shape on the other side 00:17:56.78000:17:56.790 I'm not totally sold on this through 00:17:58.58000:17:58.590 Spain good for this stricken fine 00:18:03.25000:18:03.260 alright that's it right - done okay give 00:18:08.33000:18:08.340 this another clean up just get the 00:18:09.44000:18:09.450 grease off and give these a wipe 00:18:14.47000:18:14.480 grease isn't a huge problem on the 00:18:16.52000:18:16.530 gaskets there for retaining oil anyway 00:18:19.34000:18:19.350 so no big issue there but I probably 00:18:23.18000:18:23.190 will put some sealant on them alright 00:18:28.30000:18:28.310 just gonna fold these and some cardboard 00:18:30.86000:18:30.870 so they don't get damaged in transit 00:18:35.17000:18:35.18000:18:39.16000:18:39.170 all right let's go I'm gonna try and 00:18:42.26000:18:42.270 clean up the bronze housing for the jobs 00:18:45.32000:18:45.330 go pump and I was fishing with my mate 00:18:48.98000:18:48.990 Steve earlier this week and he used to 00:18:51.65000:18:51.660 work as a conservator at the Maritime 00:18:53.15000:18:53.160 Museum and he was saying citric acid is 00:18:55.49000:18:55.500 the thing to use on these so I went just 00:18:58.28000:18:58.290 a supermarket today and somewhere here 00:19:00.44000:19:00.450 we go 00:19:01.03000:19:01.040 bought citric acid it's just a food 00:19:04.34000:19:04.350 grade product and he was saying about 00:19:06.71000:19:06.720 sort of five to ten percent by weight I 00:19:09.17000:19:09.180 think they say one to five percent for 00:19:11.24000:19:11.250 objects but that's if it's like a really 00:19:12.71000:19:12.720 delicate object that you're conserving 00:19:14.60000:19:14.610 for a museum and you're really worried 00:19:15.74000:19:15.750 about not damaging it I'm thinking of 00:19:17.75000:19:17.760 going to go around 10% just cause it's a 00:19:19.28000:19:19.290 large item that doesn't need a beautiful 00:19:21.29000:19:21.300 finish just to get happened faster so 00:19:23.99000:19:24.000 it's by weight so these are 75 grams so 00:19:26.93000:19:26.940 I've got six of them so what's that 450 00:19:29.45000:19:29.460 so about four and a half litres to 450 00:19:32.66000:19:32.670 grams of citric acid 00:19:48.69000:19:48.700 little bit more so it's completely 00:19:50.56000:19:50.570 covered these are the end caps for the 00:19:54.58000:19:54.590 heat exchanges that are also made out of 00:19:56.47000:19:56.480 bronze all right let it sit for uh you 00:20:00.39900:20:00.409 know a little while not too long maybe 00:20:02.56000:20:02.570 ten fifteen minutes and then check it 00:20:04.00000:20:04.010 for these items I'm gonna use the green 00:20:06.61000:20:06.620 polishing compound which is for copper 00:20:08.79900:20:08.809 brass and stainless clearly Steve knows 00:20:11.76900:20:11.779 what he's talking about because these 00:20:13.09000:20:13.100 came out really nicely so he reckoned 00:20:17.76900:20:17.779 Jess 00:20:18.22000:20:18.230 so we popped these other copper bits 00:20:20.68000:20:20.690 from the cooling system in possibly 00:20:23.26000:20:23.270 bronze as well a copper pipe definitely 00:20:24.70000:20:24.710 but maybe some bonds bits bronze copper 00:20:26.71000:20:26.720 we'll leave those influency it's gone 00:20:28.51000:20:28.520 green just from the Detroit paint that's 00:20:30.31000:20:30.320 come off it so it's taking the paint off 00:20:32.07000:20:32.080 next thing I do is stick these in a 00:20:34.18000:20:34.190 buffing wheel polish them up then we're 00:20:36.01000:20:36.020 gonna put a bit of clear coat on them 00:20:37.24000:20:37.250 okay so I've just set the bench grinder 00:20:39.66900:20:39.679 up it's soui bought this morning while 00:20:41.32000:20:41.330 he's out getting more nuts and bolts I'm 00:20:42.97000:20:42.980 just gonna polish up this water pump 00:20:44.32000:20:44.330 housing for him or attempt to anyway 00:20:46.71000:20:46.720 look he's supplied this metal polish 00:20:50.17000:20:50.18000:21:05.60000:21:05.610 as you can see that's coming up real 00:21:07.37000:21:07.380 nice already 00:21:22.40000:21:22.41000:21:35.62000:21:35.630 down here is where the oil cooler 00:21:39.50000:21:39.510 adapter plate goes you can see these 00:21:42.35000:21:42.360 engines is a plug here and there are 00:21:45.86000:21:45.870 plugs here and the dipstick here so 00:21:48.32000:21:48.330 designed to go either way we could have 00:21:50.30000:21:50.310 that oil color this side gearbox at the 00:21:53.06000:21:53.070 front the blocks pretty much symmetrical 00:21:54.80000:21:54.810 in this case we've got this side blocked 00:21:57.26000:21:57.270 off in the old caller here but we could 00:21:59.63000:21:59.640 have the dipstick here and the oil call 00:22:01.46000:22:01.470 of it anyway that's cleaned up now I've 00:22:04.67000:22:04.680 got the paint cleared off this mating 00:22:06.41000:22:06.420 surface now so I'm gonna put a little 00:22:08.15000:22:08.160 bit of Harlem are on the two gaskets and 00:22:10.10000:22:10.110 get ready to mount this adapter plate 00:22:11.78000:22:11.790 these are the two gaskets for here like 00:22:14.72000:22:14.730 this I'll spray both sides and let that 00:22:16.70000:22:16.710 dry for a couple of minutes this is the 00:22:18.86000:22:18.870 adapter plate itself just found the 00:22:20.75000:22:20.760 right bolts for it got some new ones for 00:22:22.61000:22:22.620 the longer ones and just got a bit of 00:22:25.73000:22:25.740 fresh paint on here so I'm just letting 00:22:27.20000:22:27.210 that dry before we mount it in this 00:22:29.60000:22:29.610 temperature that won't take long to dry 00:22:31.31000:22:31.320 though so let's get the hilum art onto 00:22:33.11000:22:33.120 these gaskets and give that a chance to 00:22:34.67000:22:34.680 start to set so this is a harlem are 00:22:37.22000:22:37.230 amusing bit of a universal joint in 00:22:40.01000:22:40.020 compound i quite like your stuff alright 00:22:46.88000:22:46.890 let that dry for a bit flip it over and 00:22:48.98000:22:48.990 we'll spray the other side okay 00:22:54.94000:22:54.950 hana mars actually very sticky so it's 00:23:00.44000:23:00.450 good in that it okay help you just 00:23:04.15000:23:04.160 position gaskets and get them to stay 00:23:06.53000:23:06.540 there as well as sealing it's a bit of a 00:23:10.85000:23:10.860 double bonus 00:23:24.10000:23:24.110 so this particular cooler is the engine 00:23:26.66000:23:26.670 oil and these two hoses will go up to a 00:23:29.03000:23:29.040 remote oil filter which was mounted onto 00:23:33.47000:23:33.480 the inside of the Komi I'm just going to 00:23:36.83000:23:36.840 put a little smear of lithium grease on 00:23:39.59000:23:39.600 each bolt some people eternal I find 00:23:42.32000:23:42.330 lithium grease quite good in the marine 00:23:45.32000:23:45.330 environment there's a particular one as 00:24:06.41000:24:06.420 the heat exchanger come out this way and 00:24:10.01000:24:10.020 it takes a full flat gasket on the back 00:24:11.81000:24:11.820 here Steve also recommended this gal met 00:24:15.05000:24:15.060 metal protector so it's essentially a 00:24:17.72000:24:17.730 rust converter but it's also a sealer as 00:24:19.58000:24:19.590 well you reckon is pretty good stuff so 00:24:21.29000:24:21.300 we'll give this a whirl I think this 00:24:23.27000:24:23.280 stuff may be tannic acid based instead 00:24:26.33000:24:26.340 of phosphoric acid from memory of what 00:24:28.61000:24:28.620 he said but I can't see it here anyway 00:24:31.73000:24:31.740 I'm gonna brush some of this inside lip 00:24:34.10000:24:34.110 of the housing here which is where our 00:24:37.88000:24:37.890 sealing o-ring goes so it's a thicker 00:24:42.29000:24:42.300 consistency 00:24:47.59000:24:47.600 which i think is the seal apart okay let 00:24:54.76000:24:54.770 that work it's magic for a while 00:24:56.85000:24:56.860 and we'll clean off the excess residue 00:24:59.52000:24:59.530 this is the output side of the heat 00:25:02.29000:25:02.300 exchanger so this goes on last anyway 00:25:11.10000:25:11.110 all right next thing to do I'm gonna 00:25:14.38000:25:14.390 spray up so I'm gonna put a high level 00:25:20.41000:25:20.420 spray on four of these gaskets 00:25:35.80000:25:35.810 all right leave that for 10 minutes and 00:25:38.51000:25:38.520 then we'll flip it to the other side in 00:25:41.03000:25:41.040 the meantime I got all my bolts ready so 00:25:42.95000:25:42.960 we've got the longer ones for the side 00:25:45.08000:25:45.090 with the o-ring housing and the short 00:25:47.69000:25:47.700 ones for the input side that doesn't 00:25:49.43000:25:49.440 have that ok Harlemites had a chance to 00:25:52.01000:25:52.020 drive for a little bit so let's go put 00:25:53.36000:25:53.370 this main heat exchanger in for the 00:25:55.10000:25:55.110 engine call it put the gasket on here 00:25:58.55000:25:58.560 first slide that right down I've cleaned 00:26:03.98000:26:03.990 the surface up here but I'm quickly 00:26:05.33000:26:05.340 gonna run a thread repair tool through 00:26:07.67000:26:07.680 these just to clean out the paint that's 00:26:09.68000:26:09.690 gone to the threads the tedious process 00:26:16.64000:26:16.650 but it's probably worth it I just figure 00:26:20.84000:26:20.850 all this stuff that's never gonna be 00:26:22.37000:26:22.380 easier than it is now plenty of space 00:26:25.70000:26:25.710 around the engine clean the threads out 00:26:32.14000:26:32.150 put some grease on the new threads 00:26:37.48000:26:37.490 definitely gonna make it easier to work 00:26:39.41000:26:39.420 on in the future 00:26:41.05000:26:41.060 he'll exchange your goes in we only got 00:26:43.61000:26:43.620 one way it's rectangular for a reason 00:26:45.32000:26:45.330 which is to make sure you don't get the 00:26:46.55000:26:46.560 wrong way so the freshwater or the 00:26:49.07000:26:49.080 coolant comes through this side salt 00:26:52.19000:26:52.200 what it comes through here 00:26:54.09000:26:54.10000:26:55.45000:26:55.46000:26:56.26000:26:56.27000:27:03.72000:27:03.730 interesting with this gal man it's gone 00:27:05.65000:27:05.660 blue inside this part which is been on 00:27:08.17000:27:08.180 five minutes and then it's gone very 00:27:10.60000:27:10.610 black on this part that's been on about 00:27:12.85000:27:12.860 ten minutes oh here's that lean cut 00:27:17.34000:27:17.35000:27:18.66000:27:18.670 another one of our highlight gaskets on 00:27:21.52000:27:21.530 the outside so a little bit of grease on 00:27:26.23000:27:26.240 the threads and a lock washer on each 00:27:28.21000:27:28.220 bolt is the service manuals 00:27:31.99000:27:32.000 recommendation this end cap has a top 00:27:37.45000:27:37.460 here which is where the arrow goes which 00:27:40.14000:27:40.150 aim and it's not gonna leak as much if 00:27:42.43000:27:42.440 it does leak or put thread sealant but B 00:27:44.35000:27:44.360 just makes it easier to change giving us 00:27:46.69000:27:46.700 a service either being a flange with the 00:27:57.82000:27:57.830 gasket probably the main thing here is 00:28:00.16000:28:00.170 just getting a nice even pressure so 00:28:03.82000:28:03.830 that it doesn't link all right so far 00:28:07.18000:28:07.190 all I can find is a quarter inch socket 00:28:10.36000:28:10.370 that fits these bolts I don't have any 00:28:13.12000:28:13.130 of our tools here this is actually for 00:28:14.80000:28:14.810 Marty's old box but it's a quarter inch 00:28:16.12000:28:16.130 and my torque wrenches are 3/8 so I'll 00:28:19.00000:28:19.010 see what I can find to solve that 00:28:20.08000:28:20.090 problem 00:28:20.64000:28:20.650 all right really like I found a 3/8 to 00:28:24.10000:28:24.110 quarter inch adapter 00:28:28.44000:28:28.45000:28:32.27000:28:32.280 yeah that was a good socket all right 00:28:36.42000:28:36.430 head socket was a half-inch this is a 17 00:28:38.85000:28:38.860 30 seconds so I think we'll still be in 00:28:45.63000:28:45.640 luck all right this is the new anode for 00:28:49.53000:28:49.540 the salt water side just gonna put a bit 00:28:53.64000:28:53.650 of thread sealant on it if I can 00:28:56.85000:28:56.860 remember which way is open this way drop 00:29:05.88000:29:05.890 this in and you can see there the flow 00:29:09.51000:29:09.520 with the salt water goes across the 00:29:11.10000:29:11.110 anode to protect the engine block from 00:29:14.10000:29:14.110 electrolysis okay let's look at the 00:29:21.81000:29:21.820 other side this side is a housing with 00:29:27.36000:29:27.370 an o-ring the seals around here so we 00:29:30.15000:29:30.160 need to gasket against here and an 00:29:32.55000:29:32.560 o-ring around here that's how it gets 00:29:34.20000:29:34.210 sealed but I'm gonna run the thread 00:29:36.81000:29:36.820 repair tool through all these threads 00:29:38.22000:29:38.230 first as well these are our last two 00:29:40.32000:29:40.330 gaskets let's bring these over so one 00:29:47.43000:29:47.440 onto the heat exchanger hopefully it's 00:29:51.06000:29:51.070 still wet enough to stick yes good Thank 00:29:55.47000:29:55.480 You Haleh ma here you've just got a 00:29:59.19000:29:59.200 little bit of rubber grease I'm gonna 00:30:01.26000:30:01.270 put some rubber grease on the o-ring 00:30:03.72000:30:03.730 that goes in there just smear it right 00:30:07.56000:30:07.570 round it's gonna help it bed into the 00:30:09.12000:30:09.130 housing as well as slide onto the heat 00:30:12.33000:30:12.340 exchanger core and we'll fit that in 00:30:16.64000:30:16.650 hopefully easily 00:30:20.79900:30:20.809 if not not all right there we go I was 00:30:25.12900:30:25.139 all right smear it around a bit not sure 00:30:29.98900:30:29.999 it matters hugely but I checked the 00:30:32.62900:30:32.639 video and this side went to the outside 00:30:34.97000:30:34.980 oh yeah the o-rings closer so that puts 00:30:37.10000:30:37.110 the o-ring closer to the heat exchanger 00:30:38.45000:30:38.460 core felt like a pretty snug fit which 00:30:48.28900:30:48.299 is good from a leaking point of view so 00:30:51.20000:30:51.210 the o-rings just sealing the gap between 00:30:53.96000:30:53.970 the outlet on the heat exchanger call 00:30:55.70000:30:55.710 and this housing and then obviously the 00:30:58.60900:30:58.619 gasket sealing the inside there 00:31:00.54900:31:00.559 one more gasket on the outside as before 00:31:07.77900:31:07.789 anode to the top 00:31:28.91900:31:28.929 what a bit of rubber grease off come 00:31:32.79900:31:32.809 this far okay all right there we go 00:31:38.71000:31:38.720 main heat exchanger core back in this 00:31:42.31000:31:42.320 one here now is the oil cooler for the 00:31:45.85000:31:45.860 gearbox what I'm gonna do to avoid that 00:32:02.14000:32:02.150 happening just going to assemble this 00:32:04.33000:32:04.340 all together just put a couple of bolts 00:32:08.56000:32:08.570 in just to keep it aligned all right 00:32:13.36000:32:13.370 I'll just make sure we can get all the 00:32:14.79900:32:14.809 others started it's before I knew penny 00:32:19.57000:32:19.580 of them up all right I'm just going to 00:32:28.72000:32:28.730 talk it up in a bit of a spiral pattern 00:32:30.46000:32:30.470 starting from the center going out all 00:32:40.29900:32:40.309 right once again hilum our coders side 00:32:43.81000:32:43.820 down onto the core and our double-sided 00:32:49.15000:32:49.160 gasket to the housing drop the core in 00:32:59.66900:32:59.679 then we'll get a couple of bolts through 00:33:03.36000:33:03.370 just to make sure everything stays 00:33:05.32000:33:05.330 aligned quite long bolts for this one 00:33:07.90000:33:07.910 because it goes all the way through 00:33:24.63000:33:24.640 now this pipe here attaches to this pipe 00:33:27.70000:33:27.710 here so it's the water pump outlet 00:33:28.83000:33:28.840 coming in here so normally you'd put 00:33:31.42000:33:31.430 your rubber seal here and a hose clamp 00:33:33.49000:33:33.500 but because the supercharger units 00:33:36.16000:33:36.170 coming off again before I finish this 00:33:38.17000:33:38.180 install I'm not gonna do that now so you 00:33:48.31000:33:48.320 can see here just a little rubber seal 00:33:50.20000:33:50.210 goes around looks like this plenty of 00:33:58.33000:33:58.340 new ones just looks like that but when 00:34:00.88000:34:00.890 we remove the supercharger we'll install 00:34:02.59000:34:02.600 that all three heat exchanger coolers 00:34:06.43000:34:06.440 back in finally I'm gonna take this out 00:34:11.23000:34:11.240 this is the old dipstick I've ordered a 00:34:13.51000:34:13.520 new one online that's taller comes up 00:34:16.39000:34:16.400 here I mean that's just virtually 00:34:18.49000:34:18.500 inaccessible once the boats in the water 00:34:20.53000:34:20.540 it's behind the starter motor under the 00:34:22.63000:34:22.640 supercharger you're never gonna check 00:34:24.61000:34:24.620 the oil and that's not what we want so 00:34:26.02000:34:26.030 I'm waiting for the new one to arrive 00:34:28.65900:34:28.669 which should bring the dipstick right up 00:34:31.21000:34:31.220 to here oh I'm pretty happy with the 00:34:33.46000:34:33.470 progress this week particularly 00:34:34.99000:34:35.000 considering I was off for most of the 00:34:37.09000:34:37.100 start of the week and our fishing trip 00:34:38.80000:34:38.810 actually had been booked for six months 00:34:40.14900:34:40.159 and whole group of us were going that 00:34:42.28000:34:42.290 was up at lake jindabyne I did do some 00:34:44.86000:34:44.870 filming wise up they're obviously not 00:34:46.78000:34:46.790 related to the troll or anything but if 00:34:48.37000:34:48.380 you like I'll edit that up and put it as 00:34:49.89900:34:49.909 a midweek video you'll probably notice a 00:34:52.18000:34:52.190 few other things are done on this injure 00:34:53.91900:34:53.929 at the moment gearboxes on etc which I 00:34:56.32000:34:56.330 filmed but I'm trying to group the 00:34:58.15000:34:58.160 videos into logical sort of you know 00:35:00.13000:35:00.140 sequences as such so this video 00:35:03.40000:35:03.410 obviously is about the heat exchangers 00:35:05.11000:35:05.120 but I will do future videos on the 00:35:07.84000:35:07.850 gearbox it's already on and you know the 00:35:10.45000:35:10.460 engine mounts blah blah blah it goes on 00:35:12.01000:35:12.020 anyway they're coming up in some future 00:35:13.84000:35:13.850 videos so until then take care I'll 00:35:15.49000:35:15.500 catch you soon 00:35:16.69000:35:16.70000:35:35.45000:35:35.460 you
