F800GS - Wheel Removal - spacer bushings?

[mystic]

Removed my front & rear wheels last week to change over to some Conti TKC80's. All done in a bit of a rush, I admit!

Today went to refit the reshod wheels to the bike. Looking closely at the Page 97/Section 8 of the Rider's Manual - for front wheel removal - it refers to a left & right side "spacing bushing" (referenced as parts 6 & 7 in the manual).

For the rear wheel - (Page 101/Section 8) - it states:

"The spocket and the pacer sleeves on left and right are loose fits in the wheel. Make sure that these parts are not damaged or lost on removal"

Here's my question: I appear to have a total of only 3 spacers for both wheels! Have I lost one in my rush to take the lose wheels over to the tyre fitters?

To add to the mystery - I did a Google search and pulled up BMW Motoradd's Pdf file of the bike's Rider Manual - see HERE

Discovered that the online manual doesn't mention anything about:

removal of spacer from the right-hand side of the front wheel hub

also - the Pdf file mentions nothing about "The spocket and the pacer sleeves on left and right are loose fits in the wheel. Make sure that these parts are not damaged or lost on removal", as described in the paper version supplied with the bike!?

Am I getting paranoiac? ...... being a numpty ..... or missing something here

Should I have four spacers? - have I lost one?

Could anybody who's had both wheels out recently put me straight please?

you should have 4! mine are all broken up and are being replaced under warranty in a couple of weeks. you should get that sorted!

When I did mine at the weekend I'm pretty sure there was only one spacer on the front axle..

 

[BM_donator]

I had exactly the same panic

Do not worry - there are only 3 spacers.

The spacer on the side the front axle is fed in from is built into the axle itself. There is no additional spacer that side.

Put it together and you'll see all should be OK.

Have not had my front wheel off as yet but find it odd that all 3 answers are different. Assume the first two are wrong.

sorry, i was talking about the rear wheel. i haven't checked my front. definitely 4 for the rear.

First -thanks to all who posted

Now know the answer to my question, having examined the dealer's Micro-fiche of the relevant bits in detail:

On the 800GS there are:

Front Wheel: ONE external spacer bushing to the right side (as you're sitting on the bike!)

NB. the left side doesn't require one as the axle is shaped / stepped ..... and simply slides in as far as it will go!

Rear Wheel: TWO external spacer bushings - (note they are not identical)


Note to myself - next time wheels removed note CAREFULLY what goes where!

Has anyone had this much wear on these spacer bushings? Is it normal for a bike with 2700 miles?
I am thinking of asking the dealer to check them out and replace them.. I need to get the radiator hose fixed as it's starting to come out now as well so I was giving the bike a check and found these spacers like this .

Cheers!

Hi
That is way to much wear,I have never seen anything like this on any Bmw bike I have owend (since 2000 6 bikes)
On my F800 gs which have done 22000 km,there is wear in the grease,and on the spacer itself,almost nil.
Must be made out of cardboard.Should be canged for free ,by dealer.

Rear wheel problem.

Hi all,

I went to a tyre place to have mine replaced recently.
I was informed part way through the re-fit that on placing the rear wheel back on the bike, it had ceased!

I watched as they took the wheel back off, and removed the bearings to try to work out what was going on. Note that the rear wheel bearings had been replaced just a couple of thousand miles before under warrantly, but the bike is a few months out of warranty now.

So the bearings came out, and the guy then noticed a ring-like thing floating within the hub space but which couldn't be pulled out - seemed to be a ring with a greater diameter than the axel hole which was now just floating in there.

The guy then blamed the recent wheel-bearing change, stating that sometimes rear wheel bearing fitters use heavy machines to re-fit. He felt that the floating/loose ring was part of the rear hub responsible for seating the bearing that had been pressed too hard and broken off the hub and was now floating inapproriately in the hub.

He replaced the wheel bearings and put the rear wheel back on - one was slightly damaged. The wheel ended up spinning fine, but I was told I should look into getting a new rear hub re-build!!!

Now I'm not THAT mechanically minded, for example, I'm not even sure what you guys were talking about with respect to these spacers, etc.

Has anyone had any experience like this? Its it possible that some thin ring-like thing to do with holding the rear bearings flush has broken off and is now compromising safety or risking rear wheel ceasing? Or is this just some sort of spacer / fairly irrelevent / may just require replacement or looking into cheaply by someone who know BMW wheels?

Any help GREATLY appreciated, even if its just helping me with my terminology or giving any clues whatsoever.

Cheers,
Jon.

I can't think that it can be anything that's supposed to be there ...

Unless it's the seal from the bearing - but you should be able to pull it out if it was - the only other thing I can think of is that it actually is part of the hub ...

If too much force has been used to install the new bearing, I guess it would be possible to just crack the bearing seat off the hub (that's the 'ledge' inside the hub that the bearing sits against to stop it being pushed straight through). If that's the case then I'd hot-foot it back to the dealer who fitted the last bearing and have a quiet word ...

hmmm.. certainly the guy at the tyre place seemed to think it might be the bearing seat!
Slight problem with going back to the dealer: I've since moved to Australia, shipping the bike across and picking it up from the import contractor in Melbourne in a week or two.. quite a long way from Vines South London!! Arrgh!

 

[Greggers]

Bummer ...

But - on the bright side you've put a few miles on it with the problem, so it's at least stable ..

The answer is a new hub of course, but I know from experience that the bearings are a very tight fit (when I did my rear the bearing didn't release until the outer race had fractured ...) so as long as it is pushed into the hub properly, i.e. so that the inner spacer tube isn't too tight and can still move a little, I guess you'll be ok...

All the best

Greg

Thanks Greggers -

Yeah, I've done another 50 miles or so on it with the new bearings without any problems so far, I was there when they banged the new bearings in and it all looked pretty tight. I can't really mechanically see how it would be dangerous even with the seat missing?!? Eg- worst case scenario is bearings could wear out again prematurely but there would be warning; back wheel suddenly ceasing = not very likely.?

 

[Greggers]

Well, the bearing seat is only there to ensure that the bearing,isnt over pushed into the hub, so its not a load bearing area. As long as you have one seat then the bearing spacer tube will index the other bearing in ths correct position... But pushing it too far (eg so that the spacer tube is tight) might squeeze the bearing too much laterally when the spindle nut is tightened which will cause failure quite quickly.

It goes without saying that this doesnt work if the bearing isnt a tight fit in the hub...
