Heat ring gear to approx. 100 C (212 F) and install.

Fig. 11 Installing differential bevel gears
- If large differential bevel gears have been replaced, measure and
select new shims Fig. 12
.
- Insert large differential bevel gears with measured shims.
-
Install small differential bevel gears (turned 180 ) from their final
position, and rotate into place (arrow). - Install and align thrust washers.
- Insert threaded pieces.

Note:
From this point on, do not interchange differential bevel gears and their
respective thrust washers. Fig. 12 Adjusting differential bevel gears
- Insert large differential bevel gears with thinnest shims (0.5 mm).
-
Insert small differential bevel gears (turned 180 ) together with thrust
washers. - Drive in differential bevelgear shaft.
- Press small differential bevel gears outward.
- Press large differential bevel gears in direction indicated (arrows), and
check play.
- Determine thickest shims for large differential bevel gears (on each
side) which still just fits.
- Shims for both sides should be of equal thickness.
- Identify shims according to table. Part numbers parts catalog

0.50 0.70 0.90

Note:

The adjustment is also correct if no further play is perceptible, as long as
the differential bevel gears can still be turned (arrow).
