Determining thickness of shim S2

Formula:
S2 = S2* - backlash + lift

Example:

Inserted shim S2* 1.20 mm
- Average backlash 0.29 mm
+ Lift (constant value) 0.15 mm
= Thickness of shim S2 1.06 mm

- Determine shim(s) according to table. Part
numbers parts catalog
The following shims are available for S2

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) By using shim tolerances it is possible to find
exact shim thickness required, insert two shims if
necessary.

Checking measurement
Notes: - After installing shims S1 and S2, turn differential 5 turns in both
directions so that tapered roller bearings settle.
- Measure backlash four times on circumference.
Specifications: 0.12-0.22 mm
If the backlash lies outside the tolerances, the adjustments must be
repeated. The total shim thickness Stotal must remain the same. The individual measurements must not differ by more than 0.06 mm
from each other.
