Removing the outer ring of the roller bearing from the torque converter housing –  Remove the outer ring of the small roller bearing with tool -T20140- Procedure for extracting the outer ring → , General instructions for gearbox repairs.

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 on extraction, use tool -T20022- with claws -T20022/44- to remove the internal bearing ring

Inserting the inner ring of the roller bearing by pressure –  Place tool - U-40100/3- under the driven sprocket, without damaging the inner ring of the roller bearings. –  Fit tool -T20024- inside tool -T20152-, and rest it on the inner ring of the roller bearing.

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

Fit the driven sprocket –  Fit tool -U-40300/1- to the layshaft under the crown pinion shaft so as not to damage the bearing. –  Fit tool -U-40200/15- above the driven sprocket so that the shaft in within the tool.

Removing the inner ring of the roller bearing –  Place the engine shaft in a vice with protected jaws. –  Remove the inner ring with tool -T20022- and claws -T20022/44-.

Fitting the inner ring of the roller bearing –  Place tool -U40100/3- between the crown pinion and the roller bearing without damaging them. –  Fit tool -T20024- inside tool -T20152-, and rest it on the inner ring of the roller bearing.

Remove the outer ring of the roller bearing from the gearbox casing –  Remove the outer ring of the small roller bearing with tool -T20140- Procedure for extracting the outer ring → , General instructions for gearbox repairs.

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

Loosen and tighten the hexagon nut –  Hold the engine shaft in a vice with protected jaws -A-. –  Tighten with torque spanner -SAT 8010--B- to 145 Nm.

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