The main shaft oil seal often no longer seals completely after the engine has been dismantled. This is only noticed after everything has been reassembled, which is why we recommend replacing it during assembly.
Original BMW mainshaft oil seals (clutch/flywheel) for the crankshaft.
A complete kit with O-ring can be found below.
Fits all BMW models R45/R65/R80 and R100.
