Installing a reinforced sealing ring with a corresponding protrusion
1 - protrusion: 1.5 mm on the right side, 1 mm on the left side, 2 - crankcase, 3 - sealing ring, 4 - shaft
Since May 1988, the sealing rings of the axle shafts in the drive housing have been protected "connected cover", which prevents cutting of the sealing lip of the rings during the installation of the drive shafts.
To replace O-rings, you must use the appropriate mounting shanks to keep the ring lugs (modified).
