• Using a depth gauge with digital display (e.g. depth gauge VAS 6087 ), measure from bolting surface for drive pinion housing to highest point of universal measuring bar.

In the example, the dimension is 72.50 mm.

• Add to this dimension half the diameter of universal measuring bar VW 385/1. This value is 16.00 mm.

The second value is obtained during the measurement between outer race/large tapered roller bearing (installed in drive pinion housing) to the sanded rear side of shaft bevel gear.

• Measure this gap dimension "f" using a feeler gauge - A  -.

In the example, this measurement is 0.95 mm.

• Remove shaft bevel gear from drive pinion housing to measure third value.
