Ducati Monster Forum

So after getting my rims all fancy (powdercoated) a new tire put on and all new wheel bearings I went to remount my rim. Everything went together fine until I started to torque my rear axle nuts. The swingarm is pinching down on the wheel to the point that it won't turn. I have double checked everything including the spacer on the cush drive side of the wheel and it is all right as far as any of us can tell. Now this is where this really gets strange not only could my local Duc shop not help they are having the exact same problem with a 2001 monster and are equally confused it seems. By the way my bike is a 1995 m900 anyone with a idea or has had this troubling experience let me know what I am doing wrong before I loose my freaking mind. THANKS

Was the spacer between the bearings installed?

Sure was I double checked i when I changed the bearings

Is there a right and a wrong way to put that spacer back in or does it not matter?

I don't believe it matters.

The spacer on the sprocket side is conical and it does matter which way it goes on. Remove the wheel and turn it around. It's a common mistake.

No that spacer I am sure is correct. We were talking about the bearing spacer inside the hub of the wheel. But thanks for the input anyway.

What bit of the swingarm is "pinching down"  on what to stop the wheel turning ? 

Really It is pinching on both sides of the wheel. The left side on the spacer and on the right side the caliper mount. Anyone know what part of the wheel should the caliper mount be pressed against? The hub itself or the outer edge of the bearing? Should the bearing sit flush with the outer most lip of the wheel? The bearing Ducati sold me sits in just a bit but enough to make a difference if that's what the caliper mount is supposed to ride on. Thanks again.

Did you check to see if the numbers on the new and old bearings matched?

The caliper mount presses against the inner part of the bearing and on the other side, the narrower part of the spacer #25 presses against the inner part of the bearing.
When it's torqued down, there isn't much room between the swingarm and wheel.
I actually scanned the manual larger. Apparently, Picassa has resized them smaller.

So yesterday I was back a my local shop with the original bearings and the packaging that the new bearings came in and everything matched up just fine. I'm beginning to think about having a spacer made or just stacking a few of the right size washers behind that bearing unless the shop can come up with a better solution. Thanks for the help and suggestions.

I would quadruple check the conical spacer sprocket side to make sure the point of the cone is contacting the inner diameter of the bearing.  There is also a spacer on the inside of the sprocket carrier that does the same for the left wheel bearing.  Is it possible your rear break rotor, caliper, carrier are misaligned?  Is it possible the brake side wheel bearing is pressed in too far or not enough that when things are torqued down it is forcing the rotor to drag against the inner/outer pad?

Bearings, or their installation have to be the issue if you are assembling everything correctly.  That is the only thing that has changed.
