Differential, adjusting, 02J, 5 Spd. M/T

Special tools and equipment:

- VW 387 Universal dial gauge bracket
- VW 385/17 End measuring plate
- 30-205 Thrust plate
- VW 407 Press tool
- Measuring dial gauge
- The differential must be adjusted, when
- Transmission housing
- Clutch housing
- Differential housing or the
- Differential tapered roller bearing have been replaced.
- Adjustment overview.
- Press tapered roller outer race into clutch housing using press plate 30-205.

Note: Tapered roller bearing inner and outer races are paired. Do not interchange!

- Press tapered roller outer race into transmission housing, without adjustment shim, using press plate 30-205.
- Insert differential into clutch housing.
- Install transmission housing and tighten 5 bolts to 25 Nm.





- Mount dial gauge and "0" with 1 mm preload.
- Move differential up and down and recall play indicated on dial gauge (Example: 0.70 mm)

Determining shim thickness
The specified bearing preload is obtained by adding a constant figure (0.40 mm) to the reading obtained.
Example:





- Remove transmission housing and pull tapered roller bearing outer race out from transmission housing.
- Insert shims of correct thickness, thickest shim first.
- The following shims are available:





- If the size of shim required is larger than those listed in the table, insert two shims totaling the correct figure.
- Varying tolerances make it possible by measuring the shims to obtain the exact shim thickness required.
- Press outer race in again and tighten transmission housing securely.
