Replace Transmission Sleeve Yoke Dust cover

[txvepr]

So I installed a 5 speed in my 78 280z. Really like it and shifts well. However, 1 problem I saw when I was installing it and replacing the rear seal to the driveshaft was the very end is bent(Sleeve yoke dust cover. Looks like it was dropped and got the bottom flattened.  

And the bend has small cracks in it.

So, naturally, it leaks fluid slowly, but annoyingly.

The manual doesn't show how to pull this off. Ican't tell if there are clip rings holding it in and don't want to damage my good one getting it out. 

Does it entail removing the rear case from the center section to get at a clip or something from the inside? I would like to swap my good 4 speed one for the bent 5 speed one if at all possible. 

Thanks,

I thought I remember it's just a pressure fit into the end. I was unable to source a replacement when I went looking and ended up just getting another 5 speed to ensure it didn't leak

If it's what I'm thinking I went around mine with a wooden wedge and tapped it with a hammer. Mine wasn't leaking but rubbing where the drive shaft sled up into that. Made a scrapping sound until I tapped it out evenly. I'm not sure we're talking about the same thing though. 8^(

You won't be able to swap the rear extension housing from the 4 spd. They don't interchange like the front section.

 

You could try to push the crushed section back out. Use something like a socket extension the hit the side of it with a hammer. Don't hit the aluminium with the hammer. That will bur it up. That section is not structural. It's only purpose is to suport the seal.

Buy a seal with a rubber outer section, not one with metal and use some hylomar sealant to seal it. It won't be perfect, but it will be better than what it is now.

Looks like two problems, the seal area and the fit of the propeller shaft yoke.  I think that steel outer shield is a press fit.  You might be able to get it off by twisting and pulling.  Nissan got rid of it in later years anyway since the propeller shaft yoke has its own shield.  Once that's off you can work on the aluminum if needed.  Once it's close though I'd take Euro's suggestion and just seal up the outer edge of a rubber seal and drive it in.  You'll break the edge off if you do too much to it.

Not an uncommon problem.
