ADJUSTING PINION
Adjusting distance "E" is calculated from known
design distance "R" = 12.10 mm + deviation "I",
which is located on face of drive pinion.
1. Install bearing assembly with shims and tighten
collared nut to specified torque.
2. Install final drive case (without shims) and
tighten all hexagon nuts to specified torque.
3. Install one side bearing cover without O-ring
and secure with two bolts.
4. Adjust setring of Special Tool VW 385/l to
distance "a".
1 = Deviation "1" in l/100 mm
2 = Pair number
Note
The design of the drive pinion will not allow use
of the 5 mm thick Special Tool VW 385/17.
normally applied for adjustments.
a = 41 mm
Since Special Tool VW 385/30 includes this
5 mm distance, it is important to add 5 mm to
adjusting distance "E".
5. Slide Special Tools VW 385/4 on to 385/l.
Install Special Tool VW 385/14 with (25 mm)
dial gauge extension 9168.
