00:00:00.250 [Music] 00:00:08.86000:00:08.870 good afternoon so we're coming to the 00:00:11.77000:00:11.780 end of our time in Florida and the boat 00:00:15.01000:00:15.020 owner has requested that we do this 00:00:17.44000:00:17.450 general engine maintenance so if you 00:00:19.66000:00:19.670 look back on one of our earlier videos 00:00:22.57000:00:22.580 there's a video of changing the fuel 00:00:25.42000:00:25.430 filters on this cute little Westar bake 00:00:28.45000:00:28.460 and now we're going to change the zinc 00:00:32.04900:00:32.059 so there's a few zinc's on almost every 00:00:36.07000:00:36.080 Marine Engine as zinc's can get into a 00:00:38.95000:00:38.960 long discussion but the short version is 00:00:41.11000:00:41.120 if different types of metal and you have 00:00:44.38000:00:44.390 salt water and the salt water turns the 00:00:47.86000:00:47.870 different type of metals into a battery 00:00:49.81000:00:49.820 and eats one of the metals and that's 00:00:53.65000:00:53.660 bad because the engine needs all the 00:00:55.86900:00:55.879 metals that it has so if it starts 00:00:57.91000:00:57.920 eating one of them bad so that's a 00:01:00.54900:01:00.559 simple version if anyone's ever curious 00:01:02.88900:01:02.899 we can give you a long version but zinc 00:01:05.68000:01:05.690 is the metal that within reason burns 00:01:08.88900:01:08.899 better than everything else so there's a 00:01:11.23000:01:11.240 piece of zinc that is bolted to the 00:01:13.60000:01:13.610 engine and it's designed to sacrifice 00:01:15.99900:01:16.009 its life for the engine so that the 00:01:18.34000:01:18.350 engine continues to run today we're 00:01:21.79000:01:21.800 doing the heat exchanger which is like 00:01:23.41000:01:23.420 the radiator on a car takes ocean water 00:01:26.26000:01:26.270 up on one side engine coolant water on 00:01:30.04000:01:30.050 the other side and it transfers the heat 00:01:32.13900:01:32.149 which is why it's called the heat 00:01:33.55000:01:33.560 exchanger but because it has ocean water 00:01:36.91000:01:36.920 flowing through it and there are 00:01:38.52900:01:38.539 different types of metals in it the 00:01:40.66000:01:40.670 ocean water turns it into a battery and 00:01:42.49000:01:42.500 eats it up so it has on the ocean water 00:01:45.33900:01:45.349 side a zinc so this is the zinc for this 00:01:50.19900:01:50.209 engine and what will happen over time is 00:01:52.69000:01:52.700 that this lips called a pencil sink but 00:01:56.26000:01:56.270 this little pencil of zinc will 00:01:59.22900:01:59.239 literally burn away and get flushed away 00:02:02.30900:02:02.319 over time so we may or may not need to 00:02:05.77000:02:05.780 change it but we're at least going to 00:02:08.58000:02:08.590 check the one that's in there and in our 00:02:11.35000:02:11.360 opening conversation 00:02:12.54000:02:12.550 showing you a good one just so you know 00:02:14.28000:02:14.290 what we're talking about what you're 00:02:16.98000:02:16.990 going to look for on your heat exchanger 00:02:18.50000:02:18.510 it will probably be green and nasty 00:02:22.05000:02:22.060 looking that's the norm unless your 00:02:25.29000:02:25.300 engine to the brand-new and because it's 00:02:29.01000:02:29.020 trying to prevent corrosion and it gets 00:02:31.20000:02:31.210 corroded but you're gonna look for the 00:02:33.81000:02:33.820 head it's going to look like that on 00:02:35.97000:02:35.980 bigger engines it's bigger doesn't get 00:02:38.88000:02:38.890 much smaller than this but so you're 00:02:41.64000:02:41.650 going to look around your heat exchanger 00:02:43.10000:02:43.110 until you find something like that 00:02:46.08000:02:46.090 sticking out and then all you do is pull 00:02:49.29000:02:49.300 it out like it's a bolt and we'll do 00:02:52.80000:02:52.810 that in a second I just want you to 00:02:54.24000:02:54.250 understand what we're doing she just 00:02:56.28000:02:56.290 look around on the heat exchanger until 00:02:57.84000:02:57.850 you find something that looks kind of 00:02:59.73000:02:59.740 like that and then you pull it out a 00:03:02.49000:03:02.500 couple of things to keep in mind on this 00:03:05.13000:03:05.140 boat the engine is way up above the 00:03:08.19000:03:08.200 waterline on most boats the engine is at 00:03:11.85000:03:11.860 or below the waterline so when you pull 00:03:14.58000:03:14.590 this thing out water will pour out of it 00:03:17.78000:03:17.790 so there's two ways to stop it one as 00:03:21.57000:03:21.580 you can kind of ignore it you pull the 00:03:24.21000:03:24.220 piece out and you stick your thumb on it 00:03:25.74000:03:25.750 because there won't be a lot of pressure 00:03:27.36000:03:27.370 you can check everything do everything 00:03:29.52000:03:29.530 but if you take a thumb off water will 00:03:31.17000:03:31.180 pour in the other is you can close the C 00:03:33.87000:03:33.880 cup for your engine cool way so on this 00:03:37.32000:03:37.330 boat we don't have to do it but don't 00:03:39.03000:03:39.040 forget on most boats you either have to 00:03:42.74000:03:42.750 close the C or not be startled when 00:03:46.22900:03:46.239 water starts pouring out and you just 00:03:48.57000:03:48.580 put your thumb on it is so low pressure 00:03:51.97900:03:51.989 there's no real pressure but it is 00:03:55.17000:03:55.180 disconcerting if you forget in water 00:03:56.82000:03:56.830 start tutorial so that's the deal on 00:03:59.16000:03:59.170 this boat magic mighty is gonna have to 00:04:01.71000:04:01.720 move around but we'll show you where the 00:04:04.80000:04:04.810 zinc is on this boat and what it looks 00:04:06.63000:04:06.640 like and then we'll pull it out she may 00:04:08.85000:04:08.860 or may not be able to get a camera angle 00:04:10.53000:04:10.540 or you can see it but hopefully she can 00:04:13.62000:04:13.630 and then we'll look at it I'll show you 00:04:16.38000:04:16.390 what the old one looks like and you'll 00:04:18.48000:04:18.490 be able to compare it to the new one 00:04:19.92000:04:19.930 we'll probably change it no matter what 00:04:22.29000:04:22.300 just so that it takes some pressure off 00:04:24.63000:04:24.640 of the boat owner and because we have 00:04:27.99000:04:28.000 spares and drive it back in and that's 00:04:31.53000:04:31.540 that you do not use grease on it or 00:04:34.05000:04:34.060 anything like that you can use a 00:04:36.33000:04:36.340 dielectric grease but me personally and 00:04:39.78000:04:39.790 there's so many opinions in the world no 00:04:41.73000:04:41.740 matter what you do 00:04:42.69000:04:42.700 somebody's going to tell you that you're 00:04:44.37000:04:44.380 wrong somebody's gonna tell you that 00:04:45.99000:04:46.000 you're right for me personally I just 00:04:48.69000:04:48.700 like to clean the threads really good so 00:04:50.31000:04:50.320 we get a good electrical connection 00:04:52.16000:04:52.170 drive the new one in that's Browns on 00:04:55.47000:04:55.480 Browns so it's not a it's a low-tech 00:04:58.68000:04:58.690 thing but some people do like to use a 00:05:01.26000:05:01.270 dielectric grease okay if that's what 00:05:05.10000:05:05.110 you want to do for me I don't but it 00:05:07.47000:05:07.480 that's an opinion thing now that 00:05:09.39000:05:09.400 mandatory things and they've give you 00:05:11.76000:05:11.770 good things to search on YouTube fifty 00:05:13.62000:05:13.630 other people's opinions on it if you 00:05:16.44000:05:16.450 want you can let me know what you decide 00:05:17.58000:05:17.590 but anyway that's the deal so we're 00:05:19.77000:05:19.780 about to end this scene and go 00:05:22.98000:05:22.990 upside-down and point to where the ugly 00:05:25.50000:05:25.510 old one is pull it out and roll on to 00:05:27.96000:05:27.970 chapter 2 so far you it'll be a fraction 00:05:30.21000:05:30.220 of a second for me I don't know I might 00:05:32.37000:05:32.380 have to pump my cigar for a while we'll 00:05:34.17000:05:34.180 see if I'm wearing a different colored 00:05:36.27000:05:36.280 t-shirt it's tomorrow but it will all 00:05:39.06000:05:39.070 Rumble bumbles tumble forward and now 00:05:40.80000:05:40.810 I'll see you in a fraction of you're 00:05:42.30000:05:42.310 safe 00:05:45.31000:05:45.320 okay so we're down in the in our little 00:05:49.79000:05:49.800 fiberglass hole here and you probably 00:05:52.49000:05:52.500 have an echo echo echo but whatever so a 00:05:56.21000:05:56.220 couple of things to watch out for this 00:05:58.37000:05:58.380 bolt on the end is never the zinc that 00:06:02.54000:06:02.550 is the bolt that holds on the end cap 00:06:04.49000:06:04.500 and you can see how there's a little bit 00:06:06.59000:06:06.600 of corrosion around that's because 00:06:08.81000:06:08.820 there's always no matter how cool you 00:06:10.46000:06:10.470 are there's always a little tiny bit of 00:06:12.53000:06:12.540 saltwater that manages to escape somehow 00:06:14.84000:06:14.850 just because saltwater does that so on 00:06:19.01000:06:19.020 one or both ends almost always both ends 00:06:22.25000:06:22.260 but occasionally not but anyway if it is 00:06:24.68000:06:24.690 a if it's on the end that is the bolt 00:06:27.53000:06:27.540 that holds on the end cap and it is not 00:06:30.08000:06:30.090 the zinc and on this one this right here 00:06:34.61000:06:34.620 is the zinc if you can see how it's kind 00:06:37.37000:06:37.380 of corroded and 00:06:38.20000:06:38.210 nasty that's one of the symptoms of it 00:06:40.76000:06:40.770 being a zinc and so that is our zinc 00:06:45.20000:06:45.210 sized bolt and when I start to put a 00:06:48.52900:06:48.539 wrench on it you may or may not be able 00:06:50.18000:06:50.190 to see it but that is how you find it is 00:06:52.88000:06:52.890 you just sort of poke around until you 00:06:54.83000:06:54.840 find your bolt that is not on the end 00:06:57.95000:06:57.960 and it is somewhere else that would be 00:07:01.85000:07:01.860 the zinc and so you make sure that you 00:07:06.15900:07:06.169 have your C closed so that water is 00:07:09.08000:07:09.090 not coming in and don't forget when 00:07:11.48000:07:11.490 you're done to reopen it or you'll burn 00:07:13.21900:07:13.229 up your engine and or just live with 00:07:16.40000:07:16.410 water pouring in and so now I'm gonna go 00:07:19.15900:07:19.169 find my wrench and pull this thing off 00:07:21.74000:07:21.750 but I just wanted to show you how to 00:07:23.12000:07:23.130 find it and make a quick mention do not 00:07:25.73000:07:25.740 pull the end cap unless you need to and 00:07:29.60000:07:29.610 today is not the day that we need to so 00:07:32.12000:07:32.130 that's it for this chapter see in 00:07:34.31000:07:34.320 another fraction of your seconds alright 00:07:38.33000:07:38.340 so 00:07:39.45000:07:39.460 this is real-world boat repairs and we 00:07:44.52000:07:44.530 don't have a socket or a box end wrench 00:07:47.75000:07:47.760 but we do have a cute little adjustable 00:07:52.85000:07:52.860 so we're doing it get little adjustable 00:07:56.76000:07:56.770 because it's what we've got and you can 00:08:01.32000:08:01.330 see it was not very tight and you 00:08:05.07000:08:05.080 remembered his Browns on bronze so you 00:08:10.29000:08:10.300 don't want to go too crazy tightening 00:08:11.94000:08:11.950 these things we are above the waterline 00:08:15.08000:08:15.090 we're gonna have a little bit of water 00:08:17.19000:08:17.200 come out oh yeah we've had no zinc for a 00:08:21.09000:08:21.100 while so here you can see the way it's 00:08:29.16000:08:29.170 supposed to look compared to the way it 00:08:32.04000:08:32.050 does look huh so that's the gig and 00:08:37.14000:08:37.150 since we're here and we got the good one 00:08:39.15000:08:39.160 in the right place at the right time I 00:08:41.75000:08:41.760 can't see it from my angle but just kind 00:08:46.17000:08:46.180 of jabs up in there hey wait okay this 00:08:51.60000:08:51.610 is a sometimes problem that you have 00:08:53.58000:08:53.590 you'll notice I said water is gonna pour 00:08:56.13000:08:56.140 out yeah I didn't see it either that is 00:09:00.00000:09:00.010 because the remnants of the old zinc is 00:09:04.94000:09:04.950 still in there so we're going to do and 00:09:09.96000:09:09.970 unwanted this is why you check it 00:09:11.94000:09:11.950 regularly is to prevent from happening 00:09:14.46000:09:14.470 what just happened that the old zinc was 00:09:18.69000:09:18.700 soft but there was not enough water flow 00:09:21.81000:09:21.820 to wash away all the pieces and so 00:09:24.96000:09:24.970 there's a big piece that's stuck in 00:09:26.94000:09:26.950 there and making our life more difficult 00:09:30.09000:09:30.100 than it needs to be so now we're going 00:09:33.18000:09:33.190 to get some pic type things you can use 00:09:36.66000:09:36.670 a little screwdriver like an eyeglass 00:09:39.06000:09:39.070 screwdriver one of the tips that's my 00:09:41.58000:09:41.590 favorite as I will if I can reach it on 00:09:44.40000:09:44.410 bigger engines 00:09:45.63900:09:45.649 often easier to reach you can drill a 00:09:48.57900:09:48.589 little hole in it run a screw into it 00:09:51.24900:09:51.259 and pull it out with the screw there's a 00:09:54.06900:09:54.079 couple of tricks but basically you just 00:09:55.72000:09:55.730 pick at that little puppy until it comes 00:09:59.43900:09:59.449 out then the water will come out and 00:10:01.56900:10:01.579 then you can put the new one in the only 00:10:06.69900:10:06.709 things I have to warn you about is as we 00:10:08.71000:10:08.720 have mentioned a few times it is bronze 00:10:11.49900:10:11.509 and bronze is not a hard metal so if 00:10:14.29000:10:14.300 you're using a hard metal screwdriver 00:10:15.87900:10:15.889 with bronze threads you want to make 00:10:18.40000:10:18.410 sure you don't mess up the threads cos 00:10:20.07900:10:20.089 that gets expensive fast so I'm gonna 00:10:23.88900:10:23.899 run away and find out what kind of picky 00:10:25.68900:10:25.699 type tools we have and there's not going 00:10:28.90000:10:28.910 to be room to drill it on this engine so 00:10:32.35000:10:32.360 I'm going to run away find out what 00:10:33.91000:10:33.920 tools we have maybe even come at it from 00:10:36.42900:10:36.439 the other side so there's some hope of 00:10:38.25900:10:38.269 seeing it see if we can find a mirror 00:10:39.97000:10:39.980 mirrors are very handy just a little 00:10:42.75900:10:42.769 tidbit since you've made it this far in 00:10:44.31900:10:44.329 the video should you find yourself in 00:10:46.80900:10:46.819 Sears or any place where they sell those 00:10:49.32900:10:49.339 fun little mirrors on a stick if you own 00:10:52.26900:10:52.279 a boat and you don't have one you've 00:10:54.10000:10:54.110 made a mistake go buy one you can poke 00:10:56.71000:10:56.720 that thing around and see what's 00:10:58.15000:10:58.160 happening in all kinds of places and so 00:11:01.29900:11:01.309 we're going to see if we have one on the 00:11:02.43900:11:02.449 boat and that's it so we're gonna 00:11:06.12900:11:06.139 disappear for a while and see you in the 00:11:09.06900:11:09.079 fraction of your seconds all right so 00:11:13.62900:11:13.639 you may or may not be able to hear me 00:11:15.30900:11:15.319 I'm coming in from the other side and 00:11:18.46000:11:18.470 I'm just certain scraping this thing the 00:11:22.29900:11:22.309 one thing that you do not want to do 00:11:24.66900:11:24.679 heavy on the do not want to do is shove 00:11:29.28900:11:29.299 the old piece up in it's very hard to 00:11:33.03900:11:33.049 get it out oh yeah 00:11:34.85000:11:34.860 so I'm just very lightly scraping at it 00:11:38.04000:11:38.050 staying away from the threads as much as 00:11:40.38000:11:40.390 I can and then you could probably see 00:11:45.36000:11:45.370 little pieces falling down and we are 00:11:52.16000:11:52.170 just kind of working away at this thing 00:11:56.42000:11:56.430 and the videos gonna stop because what 00:12:01.86000:12:01.870 my beautiful whitee did was she took a 00:12:04.38000:12:04.390 picture of this and I could see what was 00:12:06.93000:12:06.940 happening just stuck her phone down in 00:12:08.85000:12:08.860 there took a picture and then I could 00:12:10.14000:12:10.150 look at that picture we're gonna do that 00:12:12.57000:12:12.580 again because we don't have the mirror 00:12:14.55000:12:14.560 on the boat and I want to make sure that 00:12:17.40000:12:17.410 I don't shove this thing in but this 00:12:20.73000:12:20.740 looks like one axis or no axis and we're 00:12:24.42000:12:24.430 gonna have to drill it screw it pull it 00:12:26.61000:12:26.620 out but I'm not gonna bore you while I 00:12:29.12000:12:29.130 reach for my phone to take a picture I 00:12:31.71000:12:31.720 did the initial clean I can see things 00:12:34.47000:12:34.480 falling and the rear angle you can 00:12:36.66000:12:36.670 probably see things falling but you'll 00:12:38.25000:12:38.260 notice things have stopped falling I 00:12:41.07000:12:41.080 have cleaned as much as I can clean 00:12:43.35000:12:43.360 without pushing real hard without put 00:12:45.78000:12:45.790 your heart and you do not want to push 00:12:49.35000:12:49.360 hard because 00:12:50.96000:12:50.970 if there's a chunk of this zinc left and 00:12:53.79000:12:53.800 you shove it up inside bad bad juju mom 00:12:57.74000:12:57.750 so I'm gonna take a break grab my camera 00:13:01.17000:13:01.180 take a picture of this 00:13:02.43000:13:02.440 we might even give you a little video of 00:13:04.26000:13:04.270 the pictures because you can see what 00:13:08.63900:13:08.649 we're looking at and there but this is 00:13:10.92000:13:10.930 definitely looking like one where we're 00:13:12.72000:13:12.730 gonna have to figure out some way to 00:13:14.67000:13:14.680 drill it and put a screw in it and cut 00:13:17.55000:13:17.560 it out do it you give you the salute and 00:13:21.53000:13:21.540 see you in a few of your seconds all 00:13:27.32900:13:27.339 right so I'm still coming at this thing 00:13:30.00000:13:30.010 from upside down but you can see we've 00:13:32.76000:13:32.770 got our drill ended up Bazaar angle as a 00:13:36.30000:13:36.310 matter of fact I'm gonna ask my T do I 00:13:38.07000:13:38.080 look from side to side I can see but up 00:13:40.44000:13:40.450 and down but I look pretty straight 00:13:41.76000:13:41.770 going into that thing yeah okay cool so 00:13:44.97000:13:44.980 now we're gonna drill here hey we're 00:13:52.11000:13:52.120 gonna go the direction though so we 00:13:53.63900:13:53.649 actually drill 00:13:54.48000:13:54.49000:13:58.24000:13:58.250 now one thing when you're doing this you 00:14:01.61000:14:01.620 do not every on the not want to push 00:14:05.66000:14:05.670 very hard on this because eight you can 00:14:07.79000:14:07.800 push the piece of zinc in but be you can 00:14:11.06000:14:11.070 go through what's left 00:14:12.65000:14:12.660 we're very often there's not much left 00:14:14.72000:14:14.730 and you do not want to poke a hole 00:14:17.87000:14:17.880 anything that's in there there's a bunch 00:14:19.49000:14:19.500 of tiny little bronze tubes very easy to 00:14:23.36000:14:23.370 poke a hole in them and you do not want 00:14:25.85000:14:25.860 to do that so this is a very very gentle 00:14:28.79000:14:28.800 this is more dental type drilling than 00:14:31.10000:14:31.110 it is engine type drilling so make that 00:14:34.88000:14:34.890 mention before it start going to cutting 00:14:37.82000:14:37.830 away here 00:14:39.55000:14:39.56000:14:49.02000:14:49.030 real into this movie 00:14:55.79000:14:55.800 I just felt to go through the other 00:14:58.00900:14:58.019 water who we are through that's all you 00:15:07.46000:15:07.470 want it's just enough to be able to get 00:15:10.54900:15:10.559 the screw in 00:15:13.04000:15:13.05000:15:18.75000:15:18.760 now we're gonna find this groove 00:15:24.26000:15:24.27000:15:29.96000:15:29.970 Hey 00:15:31.18000:15:31.19000:15:32.38000:15:32.390 we're gonna go into that same a hole 00:15:34.50900:15:34.519 that we just made you hook around a 00:15:36.31000:15:36.320 little bit for that hole screw into that 00:15:41.31900:15:41.329 zinc 00:15:45.05000:15:45.06000:15:49.78000:15:49.790 not to fire the same thing don't wanna 00:15:52.48000:15:52.49000:15:54.69000:15:54.700 already so that think is so torn up now 00:15:59.35000:15:59.360 that I have a a hole in there I'm just 00:16:05.83000:16:05.840 gonna pull out the last of the chunks of 00:16:08.92000:16:08.930 it with the threads of the screw cuz 00:16:10.77000:16:10.780 it's not even firm enough to be able to 00:16:16.41000:16:16.420 pull out now this is actually probably 00:16:20.65000:16:20.660 it's no fun for me but it's a good video 00:16:23.32000:16:23.330 for you because you get to see pretty 00:16:27.31000:16:27.320 much the worst case scenario you can't 00:16:29.50000:16:29.510 get to it all that well and it's way 00:16:34.87000:16:34.880 beyond neglected and it broke it needed 00:16:41.83000:16:41.840 to be drilled it needs to be browned out 00:16:46.08000:16:46.090 is about all of the worst-case scenarios 00:16:51.10000:16:51.110 here you can see the old zinc oxide 00:16:53.89000:16:53.900 coming out on the screw to just remember 00:16:58.57000:16:58.580 watch out for your threads dumped in 00:17:00.93000:17:00.940 don't mess up your threads don't push 00:17:03.43000:17:03.440 this thing too far in because it will 00:17:05.64000:17:05.650 poke those little tubes what's bad 00:17:08.80900:17:08.819 kill your heat exchanger but just sort 00:17:13.49000:17:13.500 of clean this thing up No 00:17:22.00000:17:22.010 unfortunately the way that you tell if 00:17:25.01000:17:25.020 it's cleaned out is whether or not the 00:17:28.22000:17:28.230 new sink will fit in so if somebody will 00:17:31.94000:17:31.950 put into my other hand we have other 00:17:34.64000:17:34.650 people out of camera here putting the 00:17:38.15000:17:38.160 new sink into my hand I'm gonna just a 00:17:42.32000:17:42.330 little bit more and then if the new 00:17:47.72000:17:47.730 zinc-rich in it's clean if the new Zink 00:17:51.59000:17:51.600 does not fit in it's not clean it's just 00:17:55.64000:17:55.650 late that's one of the cool things about 00:17:58.49000:17:58.500 boat repair it's not brain surgery no 00:18:04.82000:18:04.830 offense to the brain surgeons out there 00:18:07.36000:18:07.370 maybe people would live longer if they 00:18:11.84000:18:11.850 let boat people through the brain 00:18:13.28000:18:13.290 surgery but oh yeah there you can see 00:18:18.26000:18:18.270 we're cleaning that up that's all the 00:18:20.78000:18:20.790 old zinc oxide that we're cleaning out 00:18:26.14900:18:26.159 we'll see how lucky we are here's the 00:18:32.31000:18:32.320 news incan and how that goes in there it 00:18:34.47000:18:34.480 doesn't and it doesn't so we're cleaning 00:18:38.61000:18:38.620 somewhere and I'm not gonna bore you to 00:18:42.12000:18:42.130 tears cos this could be two or three 00:18:44.54900:18:44.559 minutes or it could be a half an hour 00:18:46.39900:18:46.409 but whether it's two or three minutes or 00:18:50.07000:18:50.080 half an hour it'll be the exact same 00:18:52.16900:18:52.179 thing all you're gonna see is my little 00:18:55.23000:18:55.240 screw if you had an awesome rat tail 00:18:57.48000:18:57.490 file that would be the correct tool but 00:19:00.68000:19:00.690 this is real-world boat repairs we have 00:19:05.94000:19:05.950 a sheet metal screw so that's what we 00:19:08.76000:19:08.770 use them but if you had a cute little 00:19:13.62000:19:13.630 rat tail file that would be better and 00:19:18.26900:19:18.279 we hurt your fingers a lot less that's 00:19:22.76900:19:22.779 it so I'm gonna let my T turn off the 00:19:24.77900:19:24.789 camera I'm just gonna be doing more of 00:19:27.00000:19:27.010 the same this way this way this way 00:19:29.97000:19:29.980 that's me and over and over and over 00:19:33.72000:19:33.730 trying to clean this stuff out and then 00:19:38.21000:19:38.220 stick the new sink in and when I have it 00:19:41.85000:19:41.860 cleaned enough with the new zinc will go 00:19:44.34000:19:44.350 in and I'll have magic my t turn the 00:19:48.53900:19:48.549 camera back on yep thanks Lou salute you 00:19:52.23000:19:52.240 guys 00:19:53.75000:19:53.76000:20:02.82000:20:02.83000:20:21.98000:20:21.990 all right so we started this job in 1964 00:20:27.53000:20:27.540 it's now 2019 and it is all cleaned out 00:20:32.04000:20:32.050 that didn't take too long and as you can 00:20:34.92000:20:34.930 see the new one is in it moves freely 00:20:37.04900:20:37.059 and so at this point all you do is just 00:20:40.56000:20:40.570 slide it up in till the threads meet 00:20:43.59000:20:43.600 make sure you don't cross thread just 00:20:45.78000:20:45.790 this is a water seal and screw it in 00:20:51.21000:20:51.220 that's it that's the totality of the job 00:20:53.78000:20:53.790 so I'm gonna do the rest of the screwing 00:20:56.70000:20:56.710 and well you don't see it just because 00:20:59.58000:20:59.590 it takes a while it's a weird angle to 00:21:01.50000:21:01.510 try to do it but one thing if it does 00:21:05.40000:21:05.410 not screw easily get a wire brush one of 00:21:08.46000:21:08.470 those tiny little bronze wire brushes 00:21:10.62000:21:10.630 and clean the threads because they do 00:21:15.69000:21:15.700 not want to call and mess up the threads 00:21:17.46000:21:17.470 this is a water seal and that's it then 00:21:20.97000:21:20.980 you have your new zinc in it's all 00:21:22.56000:21:22.570 pretty they don't stay pretty for long 00:21:24.51000:21:24.520 so enjoy it while you have it and then 00:21:27.57000:21:27.580 you have changed your heat exchangers 00:21:31.32000:21:31.330 zinc so until the next video the small 00:21:35.37000:21:35.380 salute enjoy your folks 00:21:37.51000:21:37.520
