Adjusting Pinion
Note
There are different marks and codes for adjustment of the drive pinion/ring gear from
1985 models on.
1 = Pcrsche trademark
2 = Manufacturing code
3 = Serial pair number from 001 to 999
4 = Manufacturing month and year, four digits (e.g. 1084)
5 = Adjusting distance E (e.g. E 71 ,151
6 = Backlash F (e.g. F 0.18)
R,= Design distance 70.70 mm
E = Adjusting distance (R, + r)
r = Deviation from R,
With the new system (e.g. E 71.15) it is no longer necessary to look for the corresponding
design distance R. E, the adjusting distance, can be applied direct on the master gage without
calculations.
Note
In older model manual transmissions the complete drive pinion had been installed before
adjusting the pinion in the case.
This is no longer possible from 1985 models on (Transm. Type G 28/10 and G 28/l I), since
shim thickness S5 can only after determining the pinion position (shim thickness S3).
