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 5777-1 and connecting rod 5777-2 (these are included in extractor 999 5777 Extractor 999 5777 Extractor ) 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. This consists of a puller cylinder and a compressed air driven hydraulic pump.

Removing the connecting socket
