Drive pinion shaft Removing and fitting

Removing 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.

Fitting the outer ring of the roller bearing into the torque converter housing –  Place the torque converter casing on a workbench, so it is totally flat.

Removing the inner ring of the roller bearing   Note If the bearing cage breaks during the extraction then use the kit -T20022-with the adapter -T20022/44- to remove the inner ring.

Inserting the inner ring of the roller bearing by pressure –  Place the adapter -U 40100/3- under the driven sprocket, without damaging the inner ring /bearing of the conical rollers. –  Fit turning tool -T20024- inside tool tappet -T20052-, and rest it on the inner ring of the roller bearing.

Remove the driven sprocket by pressure –  Fit adapter -U 40100/2- between the driven sprocket and the parking lock gear. –  Place tappet -T20061- over the threaded shaft of the crown pinion shaft.

Fit the driven sprocket –  Fit the adapter -U 40300/1- of the base of the crown pinion shaft so as not to damage the bearing. –  Fit adapter -U 40200/15- above the driven sprocket so that the shaft is within the tool.

Removing the inner ring of the roller bearing –  Remove the inner ring using the kit -T20022- and the adapter -T20022/44-.

Fit the inner ring of the roller bearing –  Place adapter -U 40100/3- between the crown pinion and the conical roller bearings without damaging them. –  Fit turning tool -T20024- inside tool tappet -T20052-, and rest it on the inner ring of the roller bearing.

Remove the outer ring of the roller bearing from the gearbox casing –  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.

Fitting the outer ring of the roller bearing into the gearbox casing

Loosen and tighten the hexagon nut –  Secure gear shaft using protection clamps -A- on the bench vice. B -  Torque wrench kit -SAT 8010-

Tighten the nut: –  Secure the collar of the hexagon nut with a punch in the machined grooves of the engine shaft -arrows-.
