Measure dimension "e".
Turn mandrel until tip of dial gauge makes contact with end measuring plate and indicates max. deflection (return point). The measured value is dimension "e" (red number range). Example: 1.17 mm.
-
‒ Remove universal mandrel.
Note:
Finally, check again whether dial gauge with master gauge VW 385/30 in position and with 3 mm preload points to "0", otherwise repeat measurement.

-
‒ Remove shaft bevel gear and install again with determined shim S3 and distance sleeve.
-
‒ Tighten hexagon nut as described on Page 39-135
.
Checking dimension "r"
-
‒ Rotate shaft bevel gear several times in both directions.
-
‒ Insert universal mandrel and carry out check measurement.
If correct shims have been selected, the dial gauge reading anti-clockwise (red number range) must indicate the value of the inscribed deviation "r" on bevel gear with a tolerance of + 0.04 mm.
