-
Fit torque gauge 0-600 Ncm -A- onto differential.
-
Read off frictional torque.
Frictional torque specifications:
Notes: Differential with shims "S1*" + "S2*" installed
-
Insert differential in final drive housing, install cover and tighten all bolts to 25 Nm.
-
Turn differential 5 turns in both directions to settle the taper roller bearings.
-
Assemble measuring equipment.
-
Use dial gauge extension VW 382/10 (6 mm flat).
-
Set measuring lever VW 388 to dimension "a" = 60 mm.
-
Determine play between the teeth flanks as follows:
-
Turn ring gear until it makes contact with a tooth flank (end of backlash travel).
-
Set dial gauge to "0" with 1 mm preload.
-
Turn ring gear back until lying against an opposite tooth flank (backlash).
-
Read off 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.
