Carry out a visual inspection of the crankshaft (1) on the power take off
side. Slide drive gear (2) onto the crankshaft (3).
◆ NOTE: Due to the restricted tolerances it can occur that it is
difficult to slide the drive gear onto the crankshaft. In
such a case try to slide on the drive gear in a different
position. Don't use tools - don't press or strike the
drivegear onto the crankshaft.

crankshaft together with the friction washer (5) VS30. Tightening
torque 200 Nm (147.5 ft.lb). Then measure the run out (CS24).
