ok! i got it. my biggest problem was my home made press needed to be made a little better. i started with 1/2" plates and with the holes i was to weak and bent a little. so a couple pieces of channel, some welds and new holes cut and drilled. i took pixs of everything so i will get them loaded onto photobucket and do a whole write up on what i made and how it comes apart for others.

..........However, personally I think changing the swingarm oil at every normal service, could be a bit of a "over kill" . When I changed my bike's swingarm oil at the first service (5000 km) - since the advice, the oil was still in a very good condition.

Mine gets changed twice a year as I switch oil grades from winter to summer.  I consider this essential preventive maintenance that allows me to detect real trouble early (Water in the tranny, drive shaft, rear end) and to fix it before I have much worse problems.  Latte colored oil = Water degredation.

A couple of years ago my final drive oil came out "black" during one of these seasonal changes.  I realized that I was pushing grease (and dirt) from the final drive spine past the seal into the final drive when putting the rear wheel back on.  Twice a year - Yesh!

I don't know if this would be worth the effort or not, but if you have a good drive train repair shop near you, that replaces universal joints for automotive applications, it may be a more cost effective approach to replacing the universal joint itself, rather than replacing the whole 'propellor shaft' ( that's the term that is used by BMW ).

I found this out after I replaced mine about 8 years ago.

I inquired at a local 'mom and pop' repair shop near me, and was given a price quote of $40, that included the universal joint and labor charge.

Heck no I am not buying a whole new shaft!
(this has been on my mind for some time)

But it is a good heads-up for those that do not know.

The universal joint is not 'easily replaceable' like they are on automobile driveshafts.  
BMW recommends replacing the whole shaft...

There are places that advertise in The Airmail for this service.

About the only thing that may be a bit difficult, is to remove the 'staked' metal that holds the universal joint in, after that, you can press out the old universal joint with a common arbor press, and a couple of sockets.

I've been told that the universal joint bathed in gear oil, should not have any issues for a long time, a lot longer than you get out of the OEM universal joint.

The joint design isn't the most robust.

i will get them posted up when i get home, work has a block on photobucket so i cant get the links i need to post the pixs.

its real simple, two 3 inch steel channels that are cut to about 4 inches long, a couple of all thread with some nuts and washers. in the two i drilled two 5/8 holes for the all thread about three inches apart in the center and then the one i cut a 1 3/4" inch hole to dig out the snap ring.

it will make a alot more sense when i post the pixs.

I will keep that in mind, Jon.

But with postal rates these days, it may be cheaper to make one. :(

dont worry about the shipping cost. like i said i can ship it in a usps flat rate box for like $8. $8 isnt anything i would lose sleep over, so if you want it send me your address.

We can wait until I am ready to do the work.  Right now, I don't want to touch any of my tools! If I licked my socket wrench, my tongue might stick to it!  :P

So if anyone else wants to use it before me, that is fine!
