I've got my bike up on the Lift to check the rear end out as it did kinda feel like something was loose when in a corner. After getting the weight off the rear wheel I could feel a bit of slop in the rear wheel, during dissassembly I found the LHS Sprocket retainer nut was loose, no way in hell was this tensioned to 230Nm and no doubt this was the root cause for the excessive movement that would have also allowed the Double row bearing inner races to walk around and allowed water to enter trashing the bearing... BTW the Needle roller bearing is not so bad considering. All the other bearings in the swingarm are nice clean no excessive wear marks they just need a clean and some fresh grease and shes good to go. Searching the forum shows this thread with just what you need to find a replacement bearings... thank you to those who contributed and shared. https://www.ducatiforum.co.uk/threads/bearing-wheel-hub.60847/page-2 So better I ask here first before I tear shit up ...you know how this goes down sometimes !! Both bearings have the same OD so The spacer between the 2 bearings should push through from either side. My question is, with some heat applied to the Eccentric housing can I press on the Inner race of the needle bearing and the spacer ring to push out that double row bearing ? I reckon this should work out OK Thanks Breastfed
I would expect that both outer race's would sit up aganst a shoulder on each side in the eccentric housing as the circlip retains the ball bearing. Breastfed
After sleeping on this .... I pressed the Double row ball bearing out first, once the Ball bearing was out the spacer sleeve between the 2 bearings cant be removed as the spacer sleeve has a bigger OD near the needle roller bearing. I machined a tool from POM to hold the Spacer sleeve and the inner race in alignment and pressed out the Needle roller.
Here is a list of Parts that I will source.... 1 x SKF BAH-0175 (Double Row Ball Bearing https://www.123bearing.co.uk/bearing-BAH0175-SKF.php ) 1 x SKF RNA4910.2RS (Needle Roller seems readily available from any bearing supplier) 1 x INNER RING DUCATI 88110541A (50x58x38) SKF only show a 50x58x40. 1 x DUST COVER DUCATI 93010102A (58x72x4.5 GPSM SP6362 https://www.fpparis.com/en ) Hope this helps as its a much cheaper option than the OEM excentric assy from Ducati, I will check the price from the local dealer .
Hugely useful post, thank you Thought the double layer ball bearing in my Multistrada eccentric was notchy when I fitted a new disc. Followed your method to remove both the ball and roller bearings and I have clearly had a lucky escape. Given the amount of side float on both inner races, it looks like they are on the point of collapse. Andy
