B10 Biturbo - pilot bearing

[Stirling]

So the mechanic is finally putting the new clutch in and... now it needs a new pilot bearing as the old one is knackered.

Can't seem to find an Alpina-specific part number. Does anyone know if this is a standard E34 535 bit, or is indeed specific to the B10 BT?

I tried to find out what a "pilot bearing" is. In german it is "pilotlager" - and should be a part of the gearbox. So you may contact Getrag, as it's maybe a special part.

If it's a part of the Clutch it's maybe a "Drucklager" an that's a standard BMW-Part (21 51 1 223 366)

The Drucklager is what we call the thrust bearing, which is a different part.

Here is a picture of a standard E34 pilot bearing. Unfortunately this does not fit.
