differential AUDI A4 2000 B5 / 1.G 01W Transmission Pinion Shaft Ring Gear Adjustment User Guide

39-59

- Determine play between teeth flanks as
follows:

- Turn ring gear until it contacts a tooth flank
(end of backlash travel).

- Set dial indicator to 0 with 2 mm preload.

- Turn ring gear back until it contacts opposite
tooth flank (backlash).

- Read backlash and note.

-
Turn ring gear another 90 and repeat
measurement 3 times.
Notes:

If pinion shaft turns when turning differential, install 3177 clamp -A- so
that an exact backlash measurement can be made. Loosen clamping piece to turn the ring gear further.Differential must be installed with cutout for differential bevel gears
facing pinion shaft.
-
If 3177 clamp is installed, install differential 180 to final position and
repeat measurements.

Checking measurement
Note:
For transmissions without polygon bearing, use VW521/8 bushing instead
of VW521/12 shown.
Notes: - After installing shims "S1" and "S2," turn differential 5 rotations in each
direction to seat tapered roller bearings.
- Measure backlash 4 times on circumference.
Specification: 0.12-0.22 mm
If backlash lies outside tolerance, repeat adjustments. Do not change
total shim thickness "Stotal." The individual measurements must not vary more than 0.06 mm from
each other.
