Action for worn splines in sleeve




Cut a - 40 mm 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 expander999 5777 Extractor 999 5777 Extractor to get a hold.
The sleeve can also be heated with a hot-air gun or induction heater.

Installing tool




Install expander 999 5777 Extractor 999 5777 Extractor and puller rod 999 5777 Extractor 999 5777 Extractor (included in extractor 9995777) for the puller cylinder.
Puller cylinder 999 5575 PULLER CYLINDER USED WITH HYDRAULIC PUMP -5576 999 5575 Puller Cylinder Used With Hydraulic Pump -5576 is used together with hydraulic pump 999 5576 HYDRAULIC PUMP 999 5576 Hydraulic Pump (foot-operated). Alternatively tool 999 2615 Hydraulic pump 999 2615 Hydraulic Pump can be used, which 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 sleeve 999 5777 Extractor 999 5777 Extractor between the puller cylinder and the transmission. Press in the expander so that it enters the groove on the connecting sleeve.
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.

Removing the sealing ring from the gearbox




Use a screwdriver to pry out the seal.
Position drift 999 5779 Drift 999 5779 Drift on the end of the differential to protect the sealing face from damage when removing the seal. Do not damage the surfaces in the transmission housing.

Removing the sealing ring from the connecting socket




Use a screwdriver to tap the sealing ring out of the socket.
Check the mating surface for the connecting socket. The socket must be replaced if there are signs of grooves or corrosion.

Installing the connecting socket




Heat the sleeve to 150°-175°C in an oven and place the sleeve in drift 999 5778 Drift 999 5778 Drift. Set it against the transmission and tap in the sleeve until contacts the differential.
The above operation must be carried out quickly to prevent the heat spreading to the differential and causing the differential to expand.
Control measurement: the distance from the end of the connecting socket to the flat surface outside the sealing ring seat on the gearbox housing must be approximately 41 mm.

Note! Use protective gloves when handling the heated socket.Care must be also taken to prevent burns in the remaining operations.

Installing the sealing ring for the connecting socket




Lubricate the sealing ring lip and the mating surface on the socket. Use ATF fluid.
Insert the seal ring to the sleeve. Tap the sleeve into place with drift 999 5780 Drift 999 5780 Drift. Tap in the drift until it contacts the transmission housing.

Installing the sealing ring for the differential




Position guide pin 999 5779 Drift 999 5779 Drift in the end of the differential. Lubricate the seal ring's lip and the guide pin with ATF oil. Tap in the seal using drift 999 5779 Drift 999 5779 Drift. Tap in the drift until to contact with the end of the connecting sleeve.
Install the circlip for the connecting socket.
