Drive Pinion, Adjusting

Drive pinion, adjusting, 01M, 4 Spd. A/T
Special tools and equipment required

VW 385/17 End dimension plate:

VW 387 Universal dial indicator bracket:

^ Dial indicator gauge

Conditions
^ Supporting ring for drive pinion bearing is installed and secured.
^ Parking lock mechanism and parking lock gear are installed.

Adjusting





- Place two shims (each 1.5 mm thick) (arrow) onto drive pinion.
- Place output gear with tapered roller bearing onto drive pinion and tighten hex nut (41 mm AF) to 250 Nm. Engage parking lock when performing this step.





- Insert dial indicator gauge -A- and zero with a preload of 1 mm. Move drive pinion up and down. Read play at gauge and note (example 0.93 mm).

Determining shims
The specified bearing preload is achieved if the reading (0.93 mm), the preload of the bearings 0.12 mm and the amount for compression 0.10 mm are subtracted from the 2 x 1.5 mm thick shims.

Example





Shims inserted 3.00 mm

- Remove output gear. Determine size of shim on basis of table and fit onto drive pinion.
- Re-install output gear and tighten hex nut to 250 Nm and secure with drift.

Different tolerances enable the required shim thickness to be measured precisely.
