Power is transmitted from the manual transmission to the wheels thru the bevel final drive (12 : 33).

The pinion shaft runs in 3 cast iron bearing cover with two pre-assembled taper roller bearings. The bearings cannot be replaced separately, the entire bearing cover must be replaced as a unit.

The bearing cover is bolted to the transmission case. The shims (0.10 . . . 0.50 mm) for adjustment of the pinion are located between the case and the surface of the bearing cover.

The adjustment of the pinion shaft is easy done with available Porsche special tools i. e. universal master gage VW 385/1 with attachments.

Torque is transmitted from the pinion shaft (16) to the ring gear (15) and to the differential (14).

The differential (14) is bolted to the ring gear (15). The differential runs on two identical taper roller bearings (13), whose outer races are located in bearing covers (2) in transmission case (11). The shims (12) (0.10 . . . 0.50 mm) for adjustment of the ring gear are located between the side covers and the transmission case.
