Hi Folks,

Help please, with my '11 660XTZ Tenere. I have the same symptoms as Kinloo in that after a visit to a 3rd party garage and new front wheel bearings and tyre my calliper is rubbing against my disc on the right hand side.

I have removed the wheel, and found that the right side straight axle collar was pushed right inside the hub against the bearing, and so giving no spacing at all. The collars are correctly sided with the straight collar on the right side and the top hat collar on the left looking forward. I'm wondering if the wheel was rebuilt and fitted back to front but with the spacers on the correct side, and so putting the wheel off centre?

I have taken out the bearing seals and checked that the internal central spacer is there, but can't really see in which direction it's been fitted without removing and thereby knackering the bearings.

So, to help my diagnosis, can anyone please have a look and tell me if the hub side with the writing cast into it ("Grimeca") etc, and the bearing nearest the surface, should be on the left or right of the bike looking fwd? I know the top hat spacer goes on the left - is that where the bearing should be sunk farthest into the hub?


thanks a lot,

PW

Pepsi, that's great thanks -

I reckon it'll solve the problem once I turn the tyre around too, as that seems to have been fitted in the wrong direction!

It wasn't Bill Smith actually - I stopped going there after they screwed me around during a simple service and caused me a lot of hassle. I'm guessing you've some experience with them?

This is normal and how it should be. The RHS collar should have no spacing effect; if it does, you'll have alignment issues. There is no fixed spacing on the RHS, the fork position (and caliper) is completely determined by where the axle is in relation to the fork leg when the pinch bolts are nipped up.

As it is only your RH disc and caliper that are making contact (I'm assuming the LH is fine?) it can only be the fork alignment causing the issue. If it was on the left (or both sides) then the spacer could be blamed - there is only ONE spacer on the front axle and that is on the left and is held in place/position by the axle's tightening torque. Both the disc's positions are fixed in relation to the LH fork leg. The spacer however has no effect on the relationship of RH disc and caliper position; that is governed by the axle clamping position only.

I would guess that the garage that did the work didn't align the forks carefully enough by tightening the axle, compressing and releasing the forks several times and then tightening the pinch bolts. Even if they did follow the correct procedure, alignment can still get fouled up if the mudguard was not removed which, if left in place, causes the forks to splay out (and the inner side of the LH disc will contact the caliper).

As mentioned, lettering on the RHS. Also look closely at the hub - the LHS has a longer 'nose' casting (bearing carrier) protruding out from the webbing than on the RHS.

An exploded diagram might help too:

Pleides,

Thanks to you too. The hub had been installed back to front. I've swapped the tyre round and will remove the mudguard and do as you say when refitting.

I'm surprised they could crowd everything in and the wheel actually turned? I also can't really believe that they hadn't cottoned on to the fact something was amiss when they assembled it?
