John I don't know if you heard my story but when my bearing failed I was on vacation. Because of the amount of damage the failure caused it effectively ended my trip.

My wife talked me into buying a new 09 KLR to finish the vacation out west.
I'll have a very hard time letting it go.
It was uber reliable

I'm a sucker for bikes and ladies. I still love that little yellow bitch. A few nights out in the cold on the side of the road and a firm hand on my part should do wonders for her attitude. Hopefully I'll get the parts tomorrow and get back out there on Thursday.

I'm not going to marry her, however. I don't want all my luck to be of the bad variety.

Austrlia got shafted aswell!

Its ok lads, we here got shafted in Australia by BMW aswell.. Quality?? what the FARK is that?
the F8 is the best bike on the planet after you sort out all the shit that BMW couldn't get right, rims, suspension, bearings only to mention a few..

BMW can piss off! they make me mad, my daughters chinese import 4 wheeler has better wheel bearings and less oil leaks than my F8, it will probably outlast the Bemma aswell

Now to the bearing issue.. ive had issues as well,one collapsed and the others were buggered, all seals and bearings were replaced, stuff BMW warranty, they will only put back in the crap they started with so i took into my own hands. they are a chinese bearing by the way,they used one NSK out of the 5 needed..

so i have replaced all seals and bearings with high speed bearings and good seals on a few mates bikes as well, dont waste your time with ceramic just use a good sealed bearing , Timken, NSK or something similar.

tell everyone you know who owns a F8 or F6 twin, replace them now no matter how many klms they have done because they will fail, whether at home or in the middle of nowhere just replace them..

F.U BMW , where has the quality gone?

Not sure that I agree with that. I have 38k miles on one of my bikes with zero issues. It's never been back to the dealer since the day I bought it. O wait, I lost a chain guard screw on the way to Great Slave Lake (after 1500 miles of dirt), so it's not perfect.

LilGS would you by chance have the part no's (not the bmw part No, the bearing code No) for those bearings and seals?
Something that has bothered me is the wheel spacers, they bear on a seal at the inner end, how is this lubed? One of the seals on my bike appears to be falling apart already.
I'm with you on the quality thing, if they didn't have BMW written on them you'd reckon they were a cheap peice of junk.
For instance the headlight support that on the boxers is steel tubing, on the F8 it's plastic, have a look at it, it is complex and no doubt hugely expensive, but it is as weak as piss, I know, I've busted mine in a low speed off, I fixed it with a bit of sheet steel and pop rivets, but it sure doesn't smack of quality.

Citation? I did a search here for DL650 vavle guides and V-Strom valve guides and only got a couple of results.

bEARING FAILURE

I just got thru reading F800Riders.org and they have mentioned several problems with the same bearing. Will BMW address this problem. I'd rather pay extra for a reliable bearing then be broke down with so little miles on the bike.

Not a problem, i will post this in the Aussie section as well so every can be aware of this problem that clearly shouldn't have been an issue in the first place.

all right, here is the details you all need to know to rectify this problem on the F800. (I cannot verify these measurements on the F650Twin with the cast wheels.)

You will need the following:
BMW F800GS 08-09 wheel bearing/seal measurements & Part numbers












5 x 6204 high speed bearings - sealedUse a good quality bearing that you can source.


3 x 30 x 47 x 7 - 30mm ID x 47mm OD x 7mm wide- seals2 in the rear and one for front.




1 x 25 x 47 x 7 -25mm ID c 47mm OD x 7mm wide- seals



Front seal, front shaft fits into this seal on the RHS






The rear wheel uses 3 bearings, one in each end of the hub and one in the cush drive.

Tools Required for job:
Internal circlip pliars, hammer and punch, flat screwdriver or seal removing tool, bearing removal tool or long punch. be gentle on the hubs.. they will be dear!

Hints and tips..
1) some bearings may be corroded into the hub as water may have gotten in past the seals as a result of pressure washing your bike or a damaged seal. apply enough force but be aware of corrosion.

2) when you remove your aluminium spacers you will probably notice they have some deep grooves in them, if they are bad replace them or use a 30mm speedi sleeve so the seal can run on a hardened surface, the seals will last a heap longer. the speedi sleeves will cost a lot more and may not be required.

3) use rubber grease on your seals lightly so the spacers aren't dry and don't rip the new seals. if they get dry they will squel

4) there are circlips retaining the bearings, remove these first.. then fit the bearing with the circlip groove first then place the spacer in between the 2 bearings then fit the outer bearing onto the spacer leaving enough preload so you can spin the bearings freely.

5) FU BMW! you should have done this!


Cheers,
LILGS..

Yes, we had the rear bearing failure also, but I caught it early. Or actually my wife reported a slight wobble feeling in corners on her 09 F650GS. At slow speed she said it was ticking.

I put it up on centerstand and moved the wheel by hand, sure enough ticking. Tested sideways force for slack, but it was only slack at one point in rotation.

Pulled the wheel, bearing very rough rolling. Took the wheel into dealer they replaced both bearings and seals and greased well under warranty.

That was about 4000 miles, now nearly 13,000 miles and all is well.

Thanks lilgs!!! Awesome post. I guess I have some work to do. I worry about the poor guy scooting along near triple digits when that rear bearing lets go. It would be next to impossible to save it. BMW has a very serious issue here. This is definitely not a random failure as I originally thought.

My GF is an attorney. As much as I hate to get attorneys involved in anything, I feel like pointing her at the NTSB to get on this before someone gets killed. I doubt BMW will be proactive judging by recent history.

New mantra: I you love someone, don't let them ride this bike until you fix the wheel bearings.

The entire thread is about the failure but you don't get to the cause until page five.
