Preparatory work
Remove:
- the bevel gear according to Bevel gear, replacing Bevel Gear
- the circlip in the connecting socket.
Carry out corrective action at worn splines in the sleeve
Cut out a -40 mm cardboard disc and use it to prevent swarf entering the gearbox. Apply a thick bead of grease or petroleum jelly on the seal in the sleeve. Press the cardboard disc 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 using a hot air gun or induction heater.
Installing tool
Install expander 5777-1 and connecting rod 5777-2 (these are included in extractor 999 5777) on 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 locating pin 5779-1 in the end of the differential. Lubricate the sealing ring lip and the locating pin using ATF oil. Tap in the seal using drift 999 5779 Drift 999 5779 Drift. Tap the drift in until it is contact with the end of the connecting sleeve.
Install the circlip for the connecting socket.
Finishing
Install the bevel gear according to Bevel gear, replacing Bevel Gear
Check the gearbox oil level according to Oil level, checking Checking Oil Level
