Sealing ring connecting socket drive shaft/differential, replacing
Special tools:
As the illustrations in this service information are used for different model years and / or models, some variation may occur. However, the essential information in the illustrations is always correct.
Preparatory work
Remove:
- the bevel gear. See Bevel gear, replacing
- the circlip in the connecting socket.
Action for worn splines in sleeve
Cut a 40 mm diameter piece of cardboard and use as protection to prevent grinding chips from ending up in the transmission. Apply a thick bead of grease or Vaseline on the seal in the sleeve. Press the piece of cardboard against the seal.
Grind a groove in the inside of the sleeve to enable the expander 9995777 to get a hold.
The sleeve can also be heated with a hot-air gun or induction heater.
Installing tool
Install expander 5777-1 and connecting rod 5777-2 (these are included in extractor 9995777 ) for the puller cylinder.
Puller cylinder 9995575 is used together with hydraulic pump 9995576 (foot operated).
Alternatively, tool 9992615 can be used. This consists of a puller cylinder and a compressed air driven hydraulic pump.
Removing the connecting socket
Place a container underneath the gearbox.
Ensure that the piston rod in the puller cylinder is in the outer position. Position socket 9995777 between the puller cylinder and the transmission. Press in the expander so that it enters the channel on the connecting socket.
Apply the puller cylinder. Check that the socket between the gearbox and the puller cylinder is in contact with its support surfaces.
Remove the socket.
Check the mating surface for the connecting socket. The socket must be replaced if there are signs of grooves or corrosion.
Removing the sealing ring for the connecting socket
Remove the sealing ring from the gearbox.
Use extractor 9995069 and counterhold 9995656 .
Check that there are no seal remnants.
Removing the drive shaft sealing ring
Remove the sealing ring for the drive shaft and O-ring for the connector sleeve.
Use a screwdriver.
Check that there are no seal remnants.
Installing the O-ring and sealing ring
Install:
- a new O-ring for the connector sleeve on the differential housing
- a new sealing ring for the drive shaft.
Lubricate the seal using the wheel bearing grease, P/N 116 1241-3.
Use drift 9995654 .
Installing the sealing ring
Install the sealing ring for the connector seal.
Lubricate the seal using the wheel bearing grease, P/N 116 1241-3.
Use drift 9995657 .
Tap in the seal until the drift bottoms on its stop against the gearbox.
Use: Adhesive, part no. 116 1370
Installing the snap ring and connecting socket
Install:
- the circlip for the socket
- the sleeve in gearbox with the long splined section (2) toward the gearbox.
Use a rubber mallet to knock in the sleeve.
