Bearing Removal

[m9hundo]

I've had success by heating (heat gun) the outer part of the wheel surrounding the bearing and adding a little WD40.  I've had them fall right out with no punch.  Regardless, a little heat would help with the punch method.  When reinstalling the bearings, throw them in the freezer (they will shrink a bit) then heat up the wheel where the bearing will sit with the heat gun. Do this for about 5 minutes constantly working around the area, don't stay in one area to long.  Run to the freezer, grab a shrunken bearing and find a drift the size of the bearing (outside diameter), a piece of pipe or socket will work.  Hammer in gently and make sure the bearing goes in evenly.

Good luck

Great advice.  I've got a heat gun aready too.  Thanks.

Changed the belts and checked all my valve clearances last night.  The project is moving along.

Just an update...  I got a different punch and was able to knock the bearings right out by using the notch on the spacer.  Then, using a heat gun, I heated up the wheel and used a different punch to knock the cush drive bushings out.  I had to pound on them for a while with a small sledge hammer but they eventually came out.  What a pain in the ass.  Now it's time for the powder coaters...

I'm at the same point you were when you posted this, I'm stripping the wheels to have them powder coated. I've just run into the cush drive problem too. After you drove them out, were you able to reuse them or did you buy a new set? If you bought new, did you just get them from a Ducati dealer?
How'd the whole project turn out? Are there pics posted anywhere?

Please don't even _think_ of reusing bearings after you've had to pound them out. They'll cost you a few bucks each at a bearing supply place, even at "outrageously marked up when put into Ducati branded bag" prices at a dealer should be under $20 a piece.

Just buy new ones.

Cush drive bearings were cheap IMO around $65 for the set. Mine were toast anyway when they were replaced.

Can't ssem to find the cush bushings for the rear wheel on my 2001 S4. Any online sources? I'm in Okinawa Japan and the Duc dealer here leaves a bit to be desired.

This is from the old board's non-OEM parts thread:

Sprocket carrier bearings: Ducati part # 75162.3075 - SKF 6006-2RS (30 x 55 x 13)

If that Ducati part number matches up with your bikes numbers, you should be able to go to any bearing supply place and ask for a 6006-2RS... (from the old thread, that's the part for at least an '02 M750 as well as my '99 M750, so its quite likely to be right for your 01 S4)

Got the bearings for the axle I need the "silencers" as the manual calls them. The 6 rubber bushing type things that were a PITA to remove.
