I canít seem to find a thread on this. Thereís a needle bearing inside of the input shaft. Could someone tell me how to remove/replace it without taking the engine apart?
Sometimes you can pull them out from the clutch side with a pick, or wind a tap into it and pull it out, if you have access to a small blind bearing puller that would be best. Failing that you can tap it out using a long rod or similar, take the slave cylinder off, remove the pushrod and do it from that side.
Some times you drill it out, others you need to split the outer sleeve .Engine never needs to come apart there is no benefit unless you plan to change the input shaft.
It almost never is fun, good luck
Thank you all for the response. I so sucked at googling last night, and couldn't find the old posts, so thanks so much for all the information. Now I need to find a replacement!
Ducati part # for the bearing is 70250441A and it's probably advisable to replace the little seal in front of it part # 93040491A
Also, the two little o-rings on the pushrod are part # 88641731A (1.78x4.76 if you want to source them elsewhere but they should only be about US$1 each)
Well - thanks for all the input. My local (local-ish, just 45 minutes away, and open till 7pm) Ducati dealer had the bearing, but they didn't have the small seal. I'm trying to source the seal right now. In a meantime, I pulled the old bearing out, and thanks to the information on the forum, my goodness, I was at least prepared for the nightmare. Bearing pins were falling off from the race, so I picked them out, and tried to punch it out from the other side, but I couldn't get to the lip of the bearing, so took other suggestion and used a tap, let it bite into the bearing case/race, and punched it out from the other side. "Medieval" was right, and fun it wasn't, but I got weird sadistic pleasure out of this.
