There was a lot of rust on my swingarm and thus I have sanded and beadblasted it clean. I did not have the tools for removing the driveshaft from the swingarm so I taped it all up pretty good to keep the media out, but will need a good cleaning when I'm all done.
I'm a little confused on the driveshaft diassembly. I cannot press down (by hand) the drivehshaft to note a spring in there. My bike is a 5/1980 build. Do all of them have a spring? I'm going by Cycleworks site: http://www.cycleworks.net/index.php?main_page=index&cPath=29_33_54 My preference is to not take this apart, since I'll just be painting, not powdercoating. It's getting spendy. :) Anyone know?
I'm going to replace the swingarm bearings since the races look pretty worn. Aside from the race removal tool and new bearings, what else do I need? I see something about a seal, but I'm lost. The right side is blocked by the driveshaft tube, the other has a plug...do I need to worry about that?
thanks

I believe so...a very strong spring which I doubt you could push on. I think it was introduced on the R45/R65 and then made available for other airheads.

Yes Steve, there is a spring, and no, you can't press it by hand.
You need a tool that resembles a shock compressor, I believe. Hopefully someone will chime in with more information. I've seen pictures of it on these pages, before. If you have a drill press, you can make your own, I think.
It might not be a bad idea to remove it and have the universal joint checked. It would be the perfect time to have it replaced, if necessary.
-
If you have a Haynes manual there is picture of the compressor tool. As Rob says You could probably devise something to do the same job. The splined coupling appears to be held on against the spring pressure by a wire circlip in a similar manner to the fork springs so the principle of removal is the same ... except the spring looks to be very much stronger.

There's an independent BMW shop near me... I'm going to drop it off and have him pull it apart so I can clean it right.
What about the parts list for the swing arm bearings?

Go here. Have your VIN number handy. Find all the parts you'll need.

That sounds great!
The parts list is pretty short - two new bearings. They come with races, so you don't have to worry about that.
The only thing you need is a special tool to pull the races.
$36 from Cycle Works (http://www.cycleworks.net/index.php?main_page=product_info&cPath=29_33_50&products_id=57)

And a tapered fitting for your grease gun. You should be able to find something similar at one of the better auto parts stores near you.

Even my favorite NAPA could not assist with the greaser fitting but Tractor Supply had 'em hanging on the rack next to the John Deere grease.

Tractor Supply is a cool store, as long as you live somewhat close to a farm!
