Determining thickness of shim"S2"

Formula:
"S2"
=
"S2*" - backlash + lift

Example:

Inserted shim "S2*" 1.20 mm
- Average backlash 0.49 mm
+ Lift (constant) 0.15 mm
= Thickness of shim "S2" 0.86 mm

- Determine shim(s) from table.

1) Using the shim tolerance variations it is
possible to find the exact shim thickness
required, insert two shims if necessary.

Determining thickness of shim "S1"

Formula:
"S1"
=
"S
total
" - "S2"

Example:

Total shim thickness "S
total
" for "S1"
+ "S2" 2.07
mm
- Thickness of shim "S2" 0.86
mm
= Thickness of shim "S1" 1.21
mm

Performing check measurement
Note: - After installing shims "S1" and "S2," turn differential 5 turns in both
directions so that the 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. But the total shim thickness "S
total
" must remain the same.
The individual measurements must not differ by more than 0.06 mm
from each other.
