Gearbox bearing info needed

[artman975]

Hi

I hope someone could help, any ideas where i could get hold of a list of the bearing references for the Ball race bearings in my 1150GS gearbox?

Hi there and welcome.
This should help with BWM part nos and bearing sizes (i think).

Have you tried Motorworks?They're on your doorstep and pretty reasonable.

BMW Dealer????

Hi,
I've just replaced some of the bearings in my 1150 gearbox and I bought them from the local BMW dealer - BMW dealer prices for bearings (and seals) are very reasonable and personally I don't think it's worth the bother or risk picking them up elsewhere?. The bearings in the gearbox are specific grades as regards clearances/tolerances and although a "standard" number will apply it will not be the correct "grade" - I could have just picked up the bearings at work - but because of the tolerances and the need for overall assembled shaft lengths to match BMW tolerances I stuck with originals from BMW

Good advice Grizzly

Thanks for the replies guys.
guess I will just have to wait until I have split the box for the numbers.

Cheers anyway

But don't be afraid of the bearings!! the bearings have standard external dimensions so the shaft lengths and positions should not be a problem, the only real question is "what are the internal clearances of the bearings" they will be either std or C3, C3 being a greater than std internal clearances normaly found in areas where large temperature variations are experienced.
If I was a betting man I would expect the bearings in this gearbox to be C3.

Has anyone got this info?

They are C3 .

Readily available from most bearing suppliers.

Buy them from Motorworks/Motobins or james Sherlock and you'll get BMW 'originals'.

Its what they sell... They are after all 'BMW' Dealers.. of everything apart from Brand new Bikes. They order parts from exactly the same sources as the 'Dealerships'

Yes.. they 'may' also offer 'pattern' - but you can be assured they will be an identical spec - only without the BMW premium.
