Hi all, Putting a set of new belts on the '97 900ss. The bearings seem to roll OK but they haven't been changed in my 15 years of ownership so thought I'd give it a go whilst I'm there. Is there a "best way" to remove the old bearings. They seem pretty tight on the shaft but I've offered no force at all as yet. The circlip comes off easy. Do they need to be heated or pressed off at all. Any suggestions grateful received. Does anyone have the tightening torque setting handy at all. Thanks.
They should just come off with a bit of physical persuasion...no heat required. If you decide to replace the follower bearings, they are quite expensive unfortunately. Torque is 26Nm
When replacing the cambelt tensioner bearings on a 1997 Ducati 900SS, the old bearings can be removed by first taking off the circlip, then using heat (around 100°C/212°F) to expand the surrounding metal for easier removal. If necessary, a Crossed Roller bearing puller or press can be used to push the bearings off the shaft, ensuring no force is applied to the outer race. New bearings should be lubricated lightly before pressing them onto the shaft using a suitable tool.
as said, the "tandem" conventional bearings normally come off easily, it's the bespoke, smaller diameter bearing removal that you need to be careful with, as they are often still attached with Loctite or equivalent, and removing without heating to "neutralise" Loctite can compromise the aluminium female thread.
Hi, Thank you for your replies with this. I completed this task a short while ago after advice from forum members here. I do have the tandem bearings and after removing them with the adjuster bracket and soaking them in WD40 and a relaxing ultrasonic bath...they came off with a slight tap from a toffee-hammer. All sorted.. Grateful as ever.. Kenny.
