Note!
Check the valve timing before the engine is started.
13.3
Crankshaft gear wheel
If only the split gear wheel has to be changed, one half of the wheel
can be removed/mounted at a time. Hereby the valve timing will
be unchanged and it will not be necessary to adjust it. However
the timing should be checked.
13.3.1 Removing of the split gear wheel
After the gearing is removed according to section 13.2.3, the split
gear wheel (6) can be removed from the crankshaft.
1 Lower the bearing cap
for main bearing No.1, see chap-
ter 10., section 10.3.1.
2 Loosen the fastening screws (27).
3 Unscrew the axial screws (26).
4 Unscrew the fastening screws (27)
and remove the gear
wheel halves.
13.3.2 Mounting of the split gear wheel
1 Clean the parting surfaces of the wheel halves
and the
contact faces of the gear wheel and the crankshaft.
2 Lower the bearing cap for main bearing No.1,
see
chapter 10, section 10.3.1.
3 Lubricate the threads
of the screws (26) and (27) with
engine oil.
4 Mount the gear wheel halves on the crankshaft
with
the parting face at right angles with the crank of cylinder No. 1
and fasten the screws (26) and (27) by hand.
5 Tighten the axial screws (26)
to a torque of 10 Nm and
check that contact is established between the gear wheel and
the crankshaft flange.
6 Tighten the fastening screws (26)
to a torque of 40 Nm.
The screws closer to the crankshaft flange are to be tightened
at first.
7 Tighten the fastening screws (27)
to stated torque. The
tightening order is the same as in the previous point.
8 Tighten the axial screws (26)
to the stated torque.
