Looking for a pinion...

[Guillom]

howya, been looking around the web for a pinion replacement for my final drive. 2000 1150GS.
That piece in the picture. Looked at motobin where i got stuff before but they don't have it. Any idea where i could find one?

I'd go to BMW for that part unless Motorworks have from a stripped down FD although I'm not sure I'd want a secondhand item. Also that part needs to be correctly shimmed in case you didn't know.

I have a complete non abs final drive, for a r1150r somewhere!

indeed, think its time to call the local BMW mech...

Shouldn't make any difference to the pinion whether its ABS or not. But that's just my 'pinion, of course...

pinion

Why do you only need a pinion? surely it would make sense to change the bevel box or if you fancy the shimming process both crown wheel and pinon. Surely if the pinion is worn / damaged the crown wheel must also be affected?. The abs difference is the bevel box case abs has a mounting hole for the sensor the non abs dosent the former requires a plug to keep the oil in.

Matched Pair?

I'm sure the crownwheel & pinion must be a matched pair and are only sold as a pair.
You don't mention what is wrong with the pinion you have? That information might be helpful too.
As Paul Young mentions, the ABS spec only affects the casing - not the pinions.
I have a "spare" non-abs bevel box - but transferring the pinions and fitting new bearings into an abs casing would require a FULL re-shim - not an easy job.

I would not like the idea of mixing a pinion, a crown wheel and possibly a casing - would expect a noisy short-lived drive.

Buy a used FD. It's much easier.
Here
and here
and in Motorworks.

Teeth on the pinion seem to have been eaten through, the ones on th crown wheel are intact, which is strange.
I get the feeling if should be a full replacement of both pinion and crown wheel, that's probably the reason it seems impossible to source the pinion on its own.

I'll look into those links Pekka, thanks

That's correct.

Works out far cheaper and simpiler buying a used final drive.
