Alright guys, welcome back to the Monserdy Special Edition 4B service series. On this episode I'm going to show you how to separate the transmission, I'm sorry, the lower unit, the foot, the drive, however you guys want to call it, separated from the whole entire transmission. I like to call this the drive, the mid section which some of you guys call it's the transmission which goes from here to here and obviously the power head. Those six, there is obviously six nuts right here, they are 916s nut. I actually created a special tool for it and it's not so special because it is just a 916s impact socket that I turned down on the lathe. For you guys that have 4Vs and have actually had to mess with it, these tolerances right here, the room that you have behind, the room that you have behind these nuts and the studs, it's very, very tight. So what I did, I just put my socket on the lathe and I turned it down all the way. Now I understand if you guys don't have a lathe and you're garage or you know, but what I have seen done, this is really, I actually didn't think of this or I would have done it myself but you can grab an angle grinder and then just grind it down. One moment just grind it until you can put it back here and as you can tell, there is, it goes all the way in. Okay so on this one, again if you want to use power tools you can if not do it by hand. I will remind you I have not done this prior, prior to this video because I wanted to show you in real time what it is like and how long it would take with the tools that we most of us have in the little tiny toolbox with the garage and what not. Me personally I like to remove the cavitation plate just because so it's not too bulky and it doesn't get in the way of anything. So the same, nice 16ths. Okay, some of this will be harder to come out but it is pretty much all the same. Okay then you have this and I do leave the this cake on because we are going to you. I'm going to show you this later on the later on the video I'm going to show you. I'm going to use this cake to hold it onto the vice so we can take it all apart. Alright so most of you noticed I took the six nuts out and it has not fallen. Why is that because we there is an O-ring there's quite a bit of a thick O-ring in here that sits on the top of the drive but also we use black RTV or this the black silicone and I need a I need a reminder right here when reinstalling this you do want to use the black RTV. There is a reason for that because one it seals really good it's really flexible when it when it hits stuff on the bottom and whatnot but also when you need to remove it again it's not going to be sticky. You can once you break a little bit it'll break and it'll fall down. If you I have had one occasion I had a guy that sent it all the way back here because he could not take it apart. This is this is a few years back they whoever did it whether it was the previous owner or hated I don't know they used red RTV and let me tell you that was a nightmare. He actually had to buy a whole new transmission casting because there was no way we could not pull it apart and what I did I grabbed the pneumatic hammer and I cut all around the transmission right here and that's the only way I could get it out. So just go to the auto part store get you some black RTV I believe it is called the ultra black from Permatex it is going to be money well spent because it is going to be super easy to remove very easy to apply and you will not have issues with it and yeah so once I have removed those nuts we want to break the RTV I'm just going to hold on to the shaft right here just in case that it breaks with the first hint. Rubber mallet don't use anything harder than rubber because you will have to buy a new lower unit and those are not cheap and you cannot find them very easy right now. So actually you can see it moves a little bit so I don't think I'm going to have to hit it really hard here we go. All right now that I know it's you can tell right here it's already separated very carefully I'm going to use my flat blade screwdriver and rock it upside down okay now this is going to be tricky normally I have another person with me helping me but it's coming down and we're all good back and forth that's it there we go now this is what you're going to have I can tell that nobody has taken this thing apart ever this thing's got several hundred hours and look at the condition of it I honestly don't think they have even replaced the oil which is good because I can tell there is no metal residue there's no no nothing like I can tell that it's been overheated or anything there's no funny noises it's been perfectly fine so I'm going to go ahead and put it on the vice um I'm gonna start picking it apart see you guys back when I'm over on the vice you
