Differential: Removing and fitting

Removing and fitting the oil pipe -1- –  Remove the bolts -arrows- from the oil pipe clamps. –  Remove the oil pipe from the torque converter casing. –  On fitting, press the oil pipe into the torque converter box by hand as far as it will go.

Fit planet gears –  Lubricate the satellite thrust washers and the satellites and fit them. –  Fit the satellites and insert the satellite shaft by tapping. –  Tap in a new tensioning sleeve. –  Lubricate the planet gear thrust washers and fit them. –  Fit the threaded component to the planet gears. –  Insert the satellite gears at 180° and rock them -arrow-.

Removing the inner ring of the roller bearing –  Place the adapter -U 40300/11- on the base and remove the inner ring of the roller bearings using the bolted strut -U 40100/1-.

Press the inner ring of the roller bearing into the gearbox casing –  Use pressure tool -T20047- with the tappet -T20152- to fit the inner ring /bearing of the conical rollers. –  Bolt up pressure tool -T20047- until the inner ring of the roller bearing is fitted.

Remove the outer ring of the roller bearing –  Fit the adapter -U 40300/13- to the shaft, supporting the bolted strut -U 40100/1- on this and remove the outer ring/ bearing of the conical rollers.

Fitting the outer ring of the roller bearing into the differential housing –  Use the tappet -T20152- together with the tappet -T20027- and fit the outer ring.

Removing the inner ring of the roller bearing –  Locate adapter -U 40300/13- on differential. –  Place the bolted strut -U 40100/1- on the adapter -U 40300/13-. Remove the bearing.   Note If the bearing cage breaks during the extraction then use the kit -T20022-with the adapter -T20022/48- to remove the inner ring.

Inserting the inner ring of the roller bearing by pressure –  Fit the inner ring of the roller bearing into the differential housing using the tappet -T20052-

Remove the outer ring of the roller bearing from the torque converter housing –  Use an allen key to screw open the hooks until the outer ring/ conical roller bearings are secured –  Screw the nut to remove the outer ring /conical roller bearings.

Press fit the outer ring of the roller bearing into the torque converter housing
