Hello, Brick House just completed a 1100 mile passage from Malaysia to Trincomalee Sri Lanka. Sri Lanka is a large island off the southeast coast of India and during the passage it just seemed like our wind speed indications weren't as high as reality even though these cups are spinning they might be a little inhibited so I'm gonna take this one screw out here that holds everything together we'll take this down to the chart table disassemble everything lube it up clean it out lube it up and then put it back together but one more thing while I'm up here I want to show you this wire I hope you can see it there's just a little broken wire right here if I had a screwdriver I could probably pull it out in a way but because of this we need a new back stay so Rebecca and I are going to fly off to Singapore in a few days that's the only place that we
01:26
can get one economically it's cheaper to fly there than to have one shipped in so we'll put on a new back stay get ready for our next passage down to Chagos way south of here. OK before we take this apart I wanted to show you the solar panels that recharge the batteries inside a few years ago these panels were opaque they were very frosted over . They had been up on top of the mast for years so to clean them up one thing you don't want to use is acetone or lacquer thinner any of those harsh cleaners but what you actually use is sandpaper and with these I started out with 400 grit paper went to 600 1000 and then ended up using 1500 grit paper and before I put this back on top the mast I'll take the 1500 grit and go over it again just to get any new corrosion off. Halfway around the world we're in Sri Lanka right now I just can't get 2000 grit paper you can
02:30
get all of these fine grit papers anywhere in America at the automotive stores and I think 200 Grit would really be the best thing to finish it off with. okay to get this apart there's one stainless steel screw right here that comes out and I'll try to take that out real quickly seems like there's a hundred threads to it one two or three four or five six seven eight nine 100 okay and as you pull it out you'll see there's a white arrow that points to the hole of course but that's because this hole is drilled at an angle and that arrow helps with realigning everything very quickly when you put it back together on the mast end side there are no markings and that's just a straight hole we'll set that aside for right now to get the bearing housing
03:34
away from the main body here we'll take a very small flat-head screwdriver and start prying up on each side and you get it up so high you'll be able to just wiggle it out like that now there's an ear here that the screw goes through and holds it down to the receiving hole down here I wanted to show this to you this half silver foil here this disc spins along with the cups and what that foil does it rides over two little sensors in here actually it's a switch there's they're all encased in plastic but if you get out you a magnifying glass and look at your own anemometer your own Raymarine an anemometer you'll see that there's two rectangular discs
04:34
in there one is a little larger than the other and as the foil passes over that switch it sends a signal to the brains inside which calculates just how fast this is spinning and turn that into a numerical figure which it sends out to the wireless instruments in the cockpit we'll set that aside for now and now to take the disk off get this out of the way there's about an eighth of an inch clearance right here we'll just pry up gently oh the stainless steel shaft when you start here it is even with the top of this round disk okay and this is just pressed on there's no threads... then we can pry this up and
05:37
pull it out there's two ears on here oh good the o-ring is already coming off there's two ears on here I'm sure you can't see because it's so black but there's an ear here and there and they line up with their receiving sockets inside. there's also an arrow which of course I'm sure you can't see but it points in the direction of the mounting tab so that helps to keep everything oriented in in proper alignment so you have the two ears and the arrow so you know just how to put this back on in this proper orientation now we want to get the cups off to do that we grab hold of the top of the shaft and give it a spin counterclockwise okay just felt it break right there now I can go ahead and
06:39
spin it very quickly there we go how nice everything fell apart that means there's no corrosion I'll pull this housing out of here so this shaft with a bearing up here goes inside and this is threaded where my thumb is for the cups to screw onto now I'll take off this bearing sometimes these get frozen on the shaft so they can be a little difficult to put on or take off in this case. In 2011 we were dismasted and what was at one time the highest part of the mast quickly became the lowest part and we dragged this whole anemometer assembly for hundreds of miles through the South Pacific up to the island of Tarawa in Kiribati
07:42
where we were able to finally stabilize everything and get the anemometer off the mast but these are the same bearings that traveled hundreds of miles and spent a week underwater in the same assembly and still they're usable today only because I've taken them apart and lube them up occasionally. So inside of this housing is another bearing just like this one to get that out I'm going to take a wood handle q-tip break it off poke it out. first time I ever did this it did not come out easily I had to use a tiny screwdriver to really shove it down and out there we go now it's coming out okay these are not hermetically sealed bearings that's just a little metal disc on top of the race so they're easy to flush out and easy to re-oil and what I'm going to do is take these and put them in this little
08:51
cup along with the housing. now I could use this contact leader for cleaning the bearings I could use mineral spirits I don't want to use this because it's under pressure it'll come back in my face I don't know think I want to deal with that today so today I'm going to use Zippo lighter fluid just put some in here I'm going to go ahead and soak this I'm going to clean it out I'm not going to a film that whole process because it takes too long in and I'll be back in a few minutes okay it's been about 45 minutes I've washed everything out I gave everything some compressed gas to try to get all the moisture out let it sit for a long time so it can dry out and evaporate and now I'm ready to put it back together you can see some of the dirt that came out of in the side of this housing and from around the
09:56
bearings themselves. Oh and one thing too, if you do have bearings that are very stiff maybe they're a bit frozen up you can take the q-tip put it down the center of the shaft and start twirling it around put it in your solution of cleaner twirl it around wash it out put more oil in and just go through that process a number of times and it'll generally free right up for you. okay for reassembly we'll start with the this metal housing will put I'm going to put just a drop of oil in first this is sewing machine oil you don't want to use anything heavier than that okay so that slides in nice and easy with that oil you're going to put two drops in okay the next thing to go is the shaft with the threads first
10:58
just drop that in now I'll squeeze that right down into the plastic housing it's just a compression fit, we'll put the cups back on and I'm okay now I just hit bottom so I'm going to give it about the same amount of torque is what it felt like when I took it apart now it just so happened on this bearing the little metal cap that seals the top of the race came off so before I put that back on I'm going to give it a shot at will directly to the bearings put the little cap on it. You can see that we just use
12:10
little pieces of tissue actually it's not tissue it's paper towels we if we could even get half sheet towels we'd hardly ever really use the whole half sheet we're so frugal on Brick House and simple things like paper towels are so difficult to get halfway around the world so we try to make all of our supplies last and don't waste anything okay now I'm pressing up from the bottom with my finger on the on the cups and down on the bearing with my thumbs it'll only go down so far anyway because the shaft is notched for it to seat at just the proper distance. okay now we're ready for this part and I'll put the o-ring on first..I want to put a little silicone grease on that will help it to seal and help preserve the rubber okay now I'm looking for the arrow and of course knowing where that hole is
13:28
next to the arrow helps to find it line that up the arrow up with the mounting tab and kind of feel around for the ears to find their holes and you might have heard it snap in okay now holding on the bottom of the cups I can put on the disc and squeeze that down and it only goes down so far so that now it's flush with the shaft I'm gonna wipe some of that silicone off of my fingertips okay now this goes back into the housing and it pretty much snaps back in place and the mounting shaft okay I'm not going to put the screw in right now I don't
14:43
want to take that time on camera to do that but what I'm going to do now is the final thing actually is to pull this cap off of the wind direction sensor there's another bearing just inside and I'm going to give that just a drop of oil I've never had this freeze up I've never had any problems with it but just in case make sure we don't have any problems just one small drop of oil put the cap back on and as soon as I put that screw in everything is done ready to put back on top the mast hey thanks a lot for watching if this was a helpful video please give us a thumbs up down there on the bottom of the screen oh also a subscribe please subscribe and thanks a lot we'll see you soon for the next video stay tuned for video number 2 where we take this part apart
