Rear bearing failure

Need some help. Yesterday took my recently acquired 06 910S for only the second major ride. It has 11k miles on the clocks. Rolled up a hundred or so fairly quick miles and pulled in for a break. When I got back on and headed home, the rear started wobbling noticeably. I pulled over and grabbed the wheel and the thing rocked back and forth about a half inch, clearly bearing failure. at the speeds I was just riding, it might have been very ugly indeed. I had read these bearings were weak in early models. Now the question: can I repair it myself if no other damage has been done? I called Fay Myers in Denver (6 hours away) and they said don't attempt it, bring it in. The parts guys said I had to order some $900 bearing package with all the necessary bits from MV. Sounds sketchy. Anyone had this failure and how did it come out and can it be done in my garage or not?

There are lots of threads on this subject here, try contacting Noel (the knurl) he has some modified hub assemblies for sale. It's fairly straightforward to remove the hub if you are reasonably efficient with spanners.

If you can't fix it with a hammer you've got an electrical problem!


No MV's in the garage anymore

rear hub?

wheeliegeezer;
yeah they're trying to sell you the "updated hub and axle" that has 2 needle bearings in it and a ball bearing that has less capacity than the one that just failed

as long as the snap ring groove is still there you can fix it for $34 + postage

remove the hub and inspect the damage 1st.....haven't heard of a needle bearing going bad yet but you never know

here is where the bearings come from;
http://www.mvagusta.net/forum/showth...rear+hub+parts

here is most of the procedure'
http://www.mvagusta.net/forum/showth...t=39392&page=2

the part about removing the bearing wasn't included

remove the Seeger ring with a sharp scribe and tap the old bearing out from the other side
heat the hub with a hot air gun, chill the bearing and drop it in
relube the needle bearing, put some waterproof on the axle and the end of the new bearing and back together it goes

if you want a hub that won't fail PM me;

bearing failed

Mitch,
thanks for the concern and offer. I am trying to decide if this is a long termer or just a summer fling. I talked to Knurl about your upgrade too. If I was racing, there'd be no question. I think for now I'm going to replace with stock from CRG and keep my eye on it regularly. If I do decide to stay with an MV I will PM you for your upgrade.
Ciao',
Andy

18k miles on mine, no problems....knock on wood. They don't ALL fail. Get Mitchy's redesign...looks good.

I used to be fast....now I just dream about it.

Bad luck mate, if we bought a new car and the wheel bearings went in the first six months of driving.... the car manufacturer would soon be out of business!!!

I don't know why we put up with it!!

These MVs are more than the average car out here!!!
