Adjustment Overview.

  • Press the outer race/tapered roller bearing with the shim into the clutch housing.

Note

  • Pay attention to the shim installed position.
  • The collar on the inner circumference faces the seal.

Volswagen Tiguan. N39-0734

  • Press the outer race/tapered roller bearing without the shim into transmission housing.
  • Insert differential into clutch housing.
  • Mount transmission housing and tighten 5 bolts.
  • Press differential in direction of clutch housing and rotate 8 times at the same time.
  • Press differential in direction of transmission housing and rotate 8 times at the same time.
  • Attach the measuring tools to the transmission housing.
  • Set the dial gauge with 1 mm pretension to "0".

Volswagen Tiguan. N39-0727

  1. 30 mm dial gauge extension
  • Move the differential up and down and read the play on the dial gauge and note it (example: 0.70 mm).

Volswagen Tiguan. N39-0759

Determining the Shim

The specified bearing pre-load is obtained by adding a constant pre-load figure of 0.25 mm to the reading obtained.

Example:

Measured value 0.70 mm
+ Preload (constant value) 0.25 mm
Shim thickness = 0.95 mm
  • Remove the transmission housing.
  • Removing the outer race/tapered roller bearing from the transmission housing
  1. Counter Support, for example, Puller - Kukko Counterstay -22/2-
  2. Internal Puller 46 to 58 mm, for example, Puller - Kukko Internal - 46-56mm -21/7-
  • Shim part number. Refer to the Parts Catalog.
  • Insert shim with the correct thickness.

Volswagen Tiguan. N39-1102

The following shims are available:

Shim Thickness (mm)
0.65 0.85 1.05 1.25
0.70 0.90 1.10  
0.75 0.95 1.15  
0.80 1.00 1.20  

If the measured shim thickness is larger than those listed in the table, then install two shims that add up to the necessary thickness. Install the thicker shim first.

Tolerance variations make it possible to find the exact shim thickness required.

  • Install the outer race again and tighten the transmission housing.

Tightening Specifications

  • Transmission housing to clutch housing.

Adjustment Overview

Note

A readjustment of the output shaft for 1st to 4th gears, output shaft for 5th/6th gears and reverse gears or differential is only required if components that directly influence the transmission adjustment, have been replaced. Note the following table to avoid unnecessary adjustments:
