Notes:
^
The preset value S2* (1.00 mm) should contribute to fast adjustment of the backlash.
^
The total shim thickness S total must be maintained.
^
Shims supplied as replacement parts go to parts catalog microfiche.
^
Measure turning torque.
A = Torque gauge, standard commercial = 0 - 600 Nm.
Turning torque specifications
Notes:
^
The tapered roller bearings for the differential gear are low-friction. Therefore, the turning torque can only be used conditionally as an inspection
value. Correct adjustment is only possible by determining the total shim thickness "S total."
^
Do not additionally treat new tapered roller bearings to measure turning torque. For this purpose, the bearings are already pre-treated with a
special oil.
^
If the ring gear and pinion set is being adjusted, a pinion adjustment (with checks) should be carried out next.
Thickness of Shim "S3," Determining
S3 = e - r
e = value determined
r = dimension (specified on ring gear in 1/100 mm)
Example:
Value "e" read on indicator 1.60 mm
Dimension "r" inscribed on ring gear -0.42 mm
Shim thickness "S3" = 1.18 mm
