2.4 Inspect contact reflection between toothed wheel cone and drive shaft cone by spot-
grinding. A uniformly distributed contact reflection must be offset to the thicker end.
2.5 Heat up toothed wheel (Fig. 1/3) to approx. 150 °C and fit onto the corresponding drive
shaft cone up to stop (conical surfaces of the cones free from grease and dry) and
immediately lubricate thread and contact surface of the hexagon screw (4) and washer
with Molykote paste “G-Rapid Plus” and tighten with a torque of
M = 60 Nm.
Insert drive housing (2) into cylinder block and crankcase carefully with toothed wheel (3)
(tooth profiles of the drive toothed wheels must mesh with each other) and mount at
the pump carrier plate with sealing compound (backlash = 0.24 mm - 0.5 mm).
2.6 Mount fuel feed pump (1) and connect fuel lines.
2.7 Check lube oil supply of the toothed wheels.
