Extracting small inner ring/tapered-roller bearing –  Before fitting the extractor, position pressure plate - MP3-467 (40-105)- on the differential housing.

Pulling off large inner ring/tapered-roller bearing –  Remove drive gear for speedometer –  Before fitting the extractor, position pressure plate - MP3-467 (40-105)- on the differential housing.

Press on small inner ring/tapered-roller bearing –  Press inner ring/tapered-roller bearing onto the differential gear housing up to the stop.

Pressing on large inner ring/tapered-roller bearing –  Press inner ring/tapered-roller bearing onto the differential gear housing up to the stop. –  Mount drive gear for speedometer

Remove crown wheel from differential gear housing

Heat crown wheel to around 100 °C and mount. –  When mounting, guide crown wheel with locating pins -A- (self-tapping).   Caution Wear protective gloves! –  Allow to cool for a while before tightening the fixing bolts. Then tighten to required torque.

Install the differential bevel gears –  Insert thrust washers for small differential bevel gears, with a little grease. –  Insert large differential bevel gears with selected adjusting washers → Fig.. –  Insert the small differential bevel gears offset at 180°, then swivel into position -arrow-. –  Insert threaded pieces. Fitting position: Heel towards the large differential bevel gear –  Place the the thrust washers so that they are aligned with the hole. –  Insert the differential bevel gear shaft up to end position and secure.

Adjust differential bevel gears –  Insert large differential bevel gears with the thinnest adjusting washers (0.5 mm). –  Insert small differential bevel gears with thrust washers, and press in the shaft.   Note Large differential bevel gears and thrust washers are no longer interchangeable. –  Push small differential bevel gears outwards and check the play in the large differential bevel gears with the hand -arrows-. –  Adjust the play by inserting the appropriate adjusting washer → Anchor.    Specified value: max. 0,10 mm   Note

The setting is correct if no more play can be detected with the hand, but the bevel gears can just be turned -arrow-. Assign the adjusting washers via → Electronic Catalogue of Original Parts. Available adjusting washers:

Adjusting washer thickness (mm)
0,50	0,70	0,90
0,60	0,80	1,00

Extracting small outer ring/tapered-roller bearing from gearbox housing

Inserting small outer ring/tapered-roller bearing in gearbox housing –  Drive in outer ring for tapered-roller bearing with thrust plate -30-205 (MP3-464)- and drift -VW 295 (MP3-403)- into the gearbox housing.

Drive outer ring/tapered-roller large out of cover of final drive –  Use a suitable shim block, for example extraction cup for secondary shaft bearings -T30067 (VW 470)- with gap in cover for final drive.

Drive outer ring/tapered-roller bearing large into the cover for final drive
