Input gear, adjusting
Special tools and equipment
- VW 382 Measuring appliance
- V.A.G 1332 Torque wrench or equivalent
- Dial indicator gauge
Work sequence
- Tighten socket head fastener to 100 Nm without dished washer and without shim.
A - Torque wrench
B - 22 mm socket
Parking lock must be engaged
- Remove socket head fastener.
- Measure distance between input gear and tapered roller bearing inner race.
- Insert dial indicator gauge and zero with a preload of 3 mm. Note reading (example 1.00 mm).
Thickness of dished washer 1.50 mm must be added to reading of = 2.50 mm.
Determining shim
The specified bearing preload is achieved if the bearing preload of 0.18 mm is subtracted from the figure obtained from the measurement (dished washer + reading) of 2.50 mm.
Example
| Dished washer + reading | 2.50 mm |
| - Bearing preload | 0.18 mm |
| = Thickness of shim | 2.32 mm |
- Determine shim on basis of table and fit onto drive shaft. Table of shims. Refer to Table of shims for drive pinion and input gear .
- Insert axial needle bearing and tighten socket head fastener including dished washer to 250 Nm.
NOTE:
Insert axial needle bearing for input shaft before tightening socket head fastener. Installed position. Refer to Removing and installing input gear,
