oil AUDI A4 1998 B5 / 1.G 01A Transmission Total Shim Thickness Workshop Manual

39-48


Note:
Make sure gauge contact surface is precisely installed and free of oil. - Place end gauge on face of pinion shaft.

- Remove master gauge and install measuring mandrel into transmission
housing.
Dial indicator extension -A- = 6.5 mm long must be installed. The VW385/3 centering disc faces cover for final drive
- Install differential cover and tighten 4 bolts to 22 Nm (16 ft lb).
- Using adjustable ring, pull 2nd VW385/3 centering disc out as far as
possible, so mandrel can only just be turned by hand.

Measuring friction torque

Notes:

Pinion shaft/hollow shaft tapered roller bearings
are low friction bearings. Therefore the friction
torque has only a limited use as a check.
Correct adjustment is only possible by
determining the total shim thickness Stotal.
Do not additionally oil new tapered roller
bearings to perform the friction torque
measurement. These bearings have already
been treated with a special oil by the
manufacturer.

Friction torque specification: - Install torque gauge, 0-600 Ncm (53 in. lb) on pinion shaft.
- Read off friction torque.

Measuring friction torque

Notes:

Differential tapered roller bearings are low
friction bearings. Therefore the friction torque
only has a limited use as a check. Correct
adjustment is only possible by determining the
total shim thickness Stotal.
Do not additionally oil new tapered roller
bearings for friction torque measurement. The
bearings have already been treated with a
special oil by the manufacturer.
