Title: spacer on drive shaft Press fit? or just stuck?
Post by: dcoffey48 on May 16, 2011, 06:12:30 AM
I'm replacing the drive shaft on my 89 GS500.  (The splines that hold the drive sprocket were wore out).  I have the old drive shaft out and disassembled  all except for the bearing and spacer on the sprocket end.  The Clymer manual simply says to remove the spacer, nothing about special tools or techniques ect.  I can not get it to move at all.  Is this supposed to be a press fit or is it just stuck?  Its not a big deal except that I did not order a new one because I was going to use the old spacer on the new shaft.  I can order a new one but if it is press fit i will need to get a shop to put it on for me.

Put the whole shaft in the freezer for about an hour or so...While waiting set up a nice clutter free work area, get a MAP torch or Oxy/Acetlyne set-up ready along with some heat resistant gloves and pliers...

After an hour or so quickly get the shaft to your work area and begin to heat just the outside of the spacer, quickly. With it expanding it should just fall right off or only need a bit of persuasion.

Thanks for the advice on the freezer trick.  I tried it but was still unable to remove the spacer.
I decided to go ahead an order a new one.  I was notified today it is on back order.   :cry:

I will either need to wait or see if I can locate another one myself.

Have you tried penetrating oils (like PB Blaster or Kroil)?

OK, if you have the whole shaft out, with the stuck spacer on it, get a piece of pipe that is longer then the shaft with an inside diameter wide enough to slide over the shaft but not the spacer. Soak the spacer with a penetrating oil of your choice, slide the pipe over the shaft and up against the spacer, proceed to beat the crap out of the pipe, hammering the spacer off.

Are you near Mass?

The spacer will press off together with the bearing. Its an interference fit and will be moderately tight, it has to be.....otherwise oil would leak between the I/D of the sleeve and the O/D of the shaft itself.

Update.

My local bike shop was kind enough to remove the old bearing and spacer for me.

I was able to get the new bearing on the new shaft by using the cold shaft hot bearing trick but not the spacer.  I guess I will make another trip to the bike shop today.

Warm the sleeve up to about 120 in your oven! or play some heat on it with a gas torch, assuming there are no scratches or other damage it should easily go on.
