Determining thickness of shim "S1"

Formula:
"S1"
=
"Stotal" - "S2"

Example:

Total shim thickness "Stotal" for "S1
+ S2" 2.12
mm
- Thickness of shim "S2" 1.06
mm
= Thickness of shim "S1" 1.06
mm

- Determine shim(s) according to table. Part
numbers parts catalog
Available shims for "S1"

Shim thickness (mm) 1)
0.45 0.65 0.85
0.50 0.70 0.90
0.55 0.75
0.60 0.80

1) Using shim tolerances it is possible to find the
exact shim thickness required; insert two shims if

Checking measurement
Note:
For transmissions without polygon bearing, use VW521/8 bushing instead
of VW521/12 shown.
Notes: - After installing shims "S1" and "S2," turn differential 5 rotations in each
direction to seat tapered roller bearings.
- Measure backlash 4 times on circumference.
Specification: 0.12-0.22 mm
If backlash lies outside tolerance, repeat adjustments. Do not change
total shim thickness "Stotal." The individual measurements must not vary more than 0.06 mm from
each other.
