Golf L4-2.0L (ABA) (1996)
-
Set up the dial indicator and zero with 1 mm preload
-
Move the differential assembly up and down and record axial play indicated by dial indicator - example: 0.90 mm
CAUTION: Do not rotate the differential during the measurement as this will cause the bearings to settle, which will result in incorrect reading.
Determining thickness of shim S1
-
The thickness of shim S1 is determined by adding:
^
Specified bearing preload (a constant, 0.40 mm)
^
The measured axial play (example: 0.90 mm)
Example:
Measured axial play (0.90 mm)
+ Preload (constant) (0.40 mm)
= Thickness of shim S1 -- (1.30 mm)
-
Remove the transmission housing and drive out tapered roller bearing outer race
-
Install shim or shims S1 of correct thickness (determined above), installing thickest shim (1.0 mm when possible) first
NOTE: Varying tolerances make it possible to select the precise shim thickness required
Available shims:
0.15mm
