ADJUSTING PINION
Pinion/Ring Gear Marked "N"
On these drive pinion/ring gear sets adjusting
distance "E" is calculated from known design
distance "R," = 74.70 mm + deviation "r",
which is located on face of drive pinion.
1 = Deviation "r" 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 385/l 7,
normally applied for adjustments.
Since Special Tool VW 385/30 includes this
5 mm distance, it is important to add 5 mm
to adjusting distance "E".
Example:
N 18 is the deviation "r" on face of pinion.
R, = design distance 74.70 mm
r
= deviation
+ 0.18mm
E = adjusting distance 74.88 mm

On these drive pinion/ring gear sets "DM"
is adjusting distance "E"
1 = Adjusting distance (75.00 mm in
example)
2 = Pair number
Note:
The design of the drive pinion will not allow
use of the 5 mm thick Special Tool 385/17,
normally applied for adjustments.
Since Special Tool VW 385/30 includes this
5 mm distance, it is important to add 5 mm
to adjusting distance "E".
