A6 Quattro Sedan V6-2.7L Turbo (APB) (2000)
1. Using the shim tolerance variations it is possible to find the exact shim thickness required, insert two shims if necessary.
Performing check measurement
Checking dimension "r"
-
Install drive pinion with determined shims "S3" and "S4" and turn 5 turns in both directions.
-
Insert universal mandrel, "determining measurement "e" and perform check measurement.
-
Read off dial gauge anti-clockwise (red scale).
^
If the shims have been correctly selected, the deviation "r" (marked on outer circumference of ring gear) must be shown - within a tolerance of
± 0.04 mm
Note: Then, (after removing universal mandrel) check again that the dial gauge, with master gauge VW 385/30 in place, indicates "0" with 2mm
preload, otherwise correct adjustments.
Measuring friction torque (check)
Notes:
^
Drive pinion/Hollow-shafted tapered roller bearings are low friction bearings. Therefore the frictional torque has only a limited use as a check.
Correct adjustment is only possible by determining the total shim thickness "Stotal."
^
Do not additionally oil new tapered roller bearing to perform the frictional torque measurement. These bearings have already been treated with a
special oil by the manufacturer.
-
Fit torque gauge 0-600 Ncm -A- onto drive pinion.
B - Socket
-
Insert tensioning sleeve 3116.
