how do you get the drive shaft out
« on: January 13, 2008, 04:41:57 PM »
ok i'm a little stumped :-?

i read my book and it said to remove the nut and then press the shaft out. my problem is a dont see a nut on the end of the drive shaft. there is a fastener that has some small splines and what looks like a snap ring. is it just a snap ring holding it in? then press it out? a special tool?

come on rob i know you have a pix of this ;D

i need to remove it so i can weld to the swing arm and then strip for powder coat.

Well, I don't remember what year bike you have, and I think the pre '81 model year it may be a different procedure, but here it is for the 'cush driveshaft'.

You need to remove the swingarm from the bike.

Then remove the swingarm from the final drive, remove the 4-12 point nuts.

You need a fixture similar to the spring compression tool used to dis-assemble McPherson struts in cages.

I think I've seen homemade tools that were just 2 plates of steel, and 2 threaded rods with nuts.

You have to compress the spring in the  drive shaft to get to a wire circlip, I believe it's at the end that mates to the final drive.

After you get the circlip out , relax the pressure on the driveshaft, by loosening the nuts, and it should come right out.

Sorry Jon, I have never had my drive shaft out...

Nor have I ever helped remove one.

As far as the early R65's being different from the later ones, I don't think so.  The R65/45 was also the test-bed for the spring cush drive on the driveshaft.

Rob,

 You're right, I just found my manual, and it is the same procedure for the earlier model year R65's.

I made one using a couple of 10" by 1 1/2" by 1/2" pieces of wood,  one for either end of the drive shaft.  I then drilled holes to connect them together with some studding with nuts on either end of the pieces of wood to compress the shaft.  You need to drill a whole in the top batten to get access to the snap ring.

did not take long.....

I whimped out on this one and had Dean at Boxerworks do it for me.  At the time I was in a hurry.  8-)

I removed the swing arm and unscrewed the final drive from the swingarm and took the assembly to him.  Best 20 bucks I ever spent!

My R65's driveshaft has been changed quite recently - by a local retired Bmw mechanic,  who worked on Bmw motorcycles all his life. He told me that the universal joint failure on my bike was due to the poor condition of the oil inside the swingarm.

According to this retired mechanic, the swingarm oil should always be changed, during normal services. I must admit - I have never changed the swingarm oil before, and it really was in a poor condition.

..........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.

I have always change final drive oil, drive shaft oil and transmission every 10,000 or once a year. Same with fork oil. Lube Transmission splines every 10,000/once a year or anytime transmission is removed. Lube wheel bearing and apply grease to final drive splines once and year or anytime the wheels are removed.

Is there any way that you can post a pic of your device and the swingarm ?   It may be hard to tell what you might be doing wrong without some sort of visual assistance..
