12. Apply master gage and set dial gage
(3 mm range) to zero with 1 mm preload.

13. Place gage plate VW 365117 on pinion
head.
14. Turn universal gage carefully unit1 dial
gage extension is perpendicular to face of
pinion head. At this moment the dial gage
needle reaches its reversing motion point,
at which the dial gage must be read.

Note
The measured value will always deviate from
the set distance "E" in antilockwise direction
(small needle of dial gage will be between 0
and i), i.e. if the dial gage has a preload of 1
mm the value deviating from 1 must be added
to shim thickness 53.
15. The determined amount of deviation is
shim thickness S3 and this shim is in-
stalled between the bearing cap and trans-
mission case. Round of this value to the
nearest 0.05 mm (e.g. 0.22 mm rounded
off to 0.25 mm).
16. Determine shim thickness S5 (see page
39 - 215).
17. Recheck adjusting distance "E" after install-
ing the shims of determined thickness. A
deviation of + 0.03 mm is acceptable.
