- Recording (backlash) indicated on gauge.
-
Turn ring gear 90 further each time and
repeat measurement 3 times.
Notes:
Determining average backlash
CAUTION!
If the individual measurements differ by more than 0.06 mm from
each other, the installation of the ring gear or the final drive gear set
Install VW386A clamping piece if the pinion shaft rotates when the
differential is turned. This way the exact backlash can be measured. Loosen clamping piece in order to turn the ring gear further.
- Add four measured values together and divide by four.
Example:
1st measurement 0.28 mm
+ 2nd measurement 0.30 mm
+ 3rd measurement 0.30 mm
+ 4th measurement 0.28 mm
= Sum of measured values 1.16 mm Result: the average backlash is 1.16 mm 4 = 0.29 mm

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.
