Title: Main shaft needle bearing replacement
Post by: ian48th on June 02, 2024, 11:03:45 AM
While trying to remove the clutch pushrod of my 2000 M900Sie I discovered wear near the right side end, then when trying to get the pushrod out the left side of the engine I noticed that the needle bearing inside the right end of the main shaft is shot.  As in needles falling out.  Not the bearing in the pressure plate.  Did I explain that clearly enough?

Looks like #31 in this diagram: https://oem-parts.hu/en/parts/ducati/2000/900/gear-box-3679231

So, how bad is this?  Any chance it can be replaced without removing the shaft?

FWIW, 53,000 miles on the bike, which is otherwise still in great shape.  Thanks!

Not sure, but I would want to inspect the whole transmission anyway.
