just under 10k miles. :bawling:

Riding down to Brightonia this morning, when I felt the rear of the bike starting to twitch as I was braking for a roundabout. Checked the back wheel and I could move it from side to side without trying. :mad:

Mate of mine rode back to his place in Portsmouth to get car and trailer so we could get the bike back home.

Rear bearing definitely gone, have not adjusted chain since its service last month, but had the rear tyre changed 10 days ago at a specialist bike tyre place and I stood there while they torqued the wheel nut up properly.

I did a search on here but could not find reference. I am trying to find out if it was something that MV would cover as a technical recall under warranty ?

Any help appreciated.

Glad you got sorted out with no further accident, gets me worried too about this problem

The rear hub bearing should have been serviced at 7500 mile check. I just took mine in for the 7500 mile service and was told that the rear hub bearing grease was drying out but they caught it in time that there was no damage. If I had not done the service I probably would have ended up like you.

Cheers

Re-do your search. Lots of threads about it. Common problem.

Not another one

yep do a search , common problem.
Theres a proper way to check the bearings (again do a search).
But if the chain is tensioned correctly as is the clamp bolts, grease the bearings every 7500 mile,& keep the water out of 'em, there have been lots of cases where the bearings will do 25,000 to 30,000 miles with out replacement.
Oh & wheel nut tension has little to no bearing on the life of the bearings , only yours:)

Thanks for the feedback. I had done a search through the forums and found all the problems that had already been experienced by other users, which have been helpful especially Cruiser's.

However what I was looking for was if anyone had actually managed to get this done under warranty. I would rather not have to spend £500+ for an upgrade if there have been any successful warranty claims based on the age and mileage of my bike.

Why 500+ upgrade? Buy new bearings and replace them or have them replaced. Make sure you torque the 2 swingarm's bolts, that hold the hub in place, at 28-32 Nm.

If the hub is destroyed, than, sorry mate, you are on your own. No warranty, 7500 miles check should be done. Though, I first checked them on my Brutale at somewhere around 20,000 miles and they were OK.

My hub collapsed and after weeks of MV denying any knowledge of the problem I tried too bet a knew HUB. Mission impossible, there is now no distributor and hence no sevice or spares in OZ. I sourced a new one out of the UK, which was great service. The new hub has some major design changing which is interesting for a design that had no problem. My pursuit of the situation got ot the point of MV and the interim distributor telling me to PISS OFF>

As far as I know, MV has not issued a recall nor provided warranty service for the rear hub bearings on a bike outside of its normal warranty period.

As Miha said, you can get bearings from the knurl. Hubs are available too for not a lot of money.

They have in sweden, but thats the only country i have heard doing the recall.

If the rear hub assy was an aircraft part then at a predetermined service interval it would be taken out, stripped and refurbished with new bearings...before failure....Question is what would be the interval based on empirical evidence ?

My guess is in the real world..If you know that from new the bearings have been correctly greased and serviced in accordance with the manual..and the hub/swing arm bolts have been correctly torqued..then there won't be much of a problem.

If you buy a second hand bike or swingarm ( as I did )....How would you know ?

Who did the service ? It stands a chance the rear hub pinch bolts may have been over torqued..

Factory specifies a swap at 24000mi/36000km.

I'd suggest that dealer discretion would be required only because it is so apparently easy to screw up pinch bolt torque or check the full travel of chain adjustment. If only your dealer has serviced the bike and can trust that the owner didn't screw up adjustment/torque and it fails during warranty I'd expect coverage. Otherwise it's a grey area of trust which usually loses out to money :)

I'm at 34,000mi/55,000km or so. Original hub bearings on silkolene rg2. I've had spare bearings in the tool box for a number years but no need to swap them yet. I've done the fronts a few times in that same period but just proactively. I should probably stop pushing my luck because we normally ride very far from home.

Yes!!! Mine was the same way. The grease smelt burnt and was "cakey". I'm going to do a winter time service each year from now on. It's easy to break down the hub and axle.
The hub needs to have service/check-up every 2500 miles, at least re-pack the bearings with grease.

rear hub

lets make it entirely clear that the problem is the 3810-2RS double row ball bearing not the 5520 needle bearing

over tensioning the chain/incorrectly torquing the hub pinch bolts are definitely the cause......or using high pressure water around the rear wheel/swingarm pivot does them in sometimes too

the bearings and seals are available from;
http://www.mvagusta.net/forum/showthread.php?t=26767&highlight=rear+hub+parts

the bearings are $34 order 2.......

each time you lube your chain, check for rear wheel play.......

if when riding the rear feels 'different', a bit like a flat tire......STOP and check it!
