Yes and it looks pretty warn out. Is this the source of the wobbly sprocket?Have you ever checked the sprocket retainer plate (or whatever it's called)?
I'm guessing yours looks a lot like this:

EDIT: This of course assumes they were still using these plates in 2000, and that you're talking about the bike in your sig.
Auumining you hav ethe same locking plate we have been discussing, there also s/b a shim behind the sprocket, there are 5 available sizes, 0.7, 0.8, 0.9, 1 and 1.1 (i presume mm). Do you have one behind your sprocket? Right size?My front sprocket rocks quite a lot on the splines. Shaft does not look worn and it is the same with brand new sprocket. I would have expected a new sprocket to be much more rigid than this. New locking plate does not control the rock.

Yes I do. I have never seen a shim behind sprocket on my bike.Auumining you hav ethe same locking plate we have been discussing, there also s/b a shim behind the sprocket, there are 5 available sizes, 0.7, 0.8, 0.9, 1 and 1.1 (i presume mm). Do you have one behind your sprocket? Right size?
That might work. I haven't found out what the acceptable variance is, I bought a full set, and went with what felt best.Yes I do. I have never seen a shim behind sprocket on my bike.
Do you just lock sprocket to shaft with keeper plate and then feeler gauge the gap behind sprocket to get shim size?
OK listen... I am not totally sure, but I bought my bike with the original sprocket installed. I definitely didnt have the shim. So I am really confused. Is it supposed to be rigid? or is there float in the sprocket?I dont have a shim behind the sprocket on my bike? I assumed all the shaft shimming was done inside the cases?
** Just had a look in the parts manual, there is a shim listed!
0670.16.170 shim.th. 0.8
0670.16.171 shim.th. 1.0
0670.16.172 shim.th. 1.2
Bizarre... There are a lot of parts on my bike missing I never knew were missing because they were never there![]()
Oops, spelt Ducati wrong must get new batteries in keyboard!Thinking about this some more, I think that shims behind the sprocket could prevent the teeth edges on the inside of the keeper plate from getting hammered. But this would still leave the teeth on the outer edge of the plate vulnerable. This side is where I usually see the wear.
Does anyone have an official view on this from Dutai themselves?
There IS a shim inside the cases (no.3), there is also one outside, no.26 shown here?On either my 1997 or my 1998. Some side play is normal. The shim goes inside the case, not behind the sprocket.
