Gearbox BE 1
Input shaft shims | 39 x 46.8mm These gaskets are available in 18 thicknesses, from 0.7 to 2.4mm every 0.1mm |
Differential bearing shims | 55 x 62 mm These gaskets are available in 12 thicknesses, from 1.1 to 2.2 mm every 0.1 mm |
Differential O-rings: | |
- left | 40 x 58 x 10 mm |
- right | 29.8 x 47 x 9.9 mm |
O-rings with casing
Since May 1988, the O-rings of the drive shafts in the drive housing have been protected "connected cover", which prevents cutting of the sealing lip of the rings during installation of the drive shafts. To replace O-rings, you must use the appropriate mounting shanks to keep the ring lugs (modified).
