- Turn ring gear back until lying against an
opposite tooth flank (backlash).

- Read backlash and note value.

-
Turn ring gear through 90 and repeat
measurements a further 3 times.
Note:
If the individual measurements differ by more
than 0.06 mm from each other, the installation of
the ring gear or the final drive set itself is not
correct. Check installation, replace final drive set
if necessary.

Determining average backlash

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 4 =
0.29 mm

Performing check measurement
Note:
Drive pinion with shim "S3" installed Differential with shims "S1" + "S2" installed
- 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, but the total shim thickness "S
total
" must remain unchanged.
The individual measurements must not differ by more than 0.06 mm
from each other.
