02.42 THE FANSHROUD - TS/TR
An aluminium fanshroud is fitted to all engines
except Build 16 which has one of sheet metal.
Removing the Fanshroud
1. Remove the flywheel.
2. Remove the two nuts and then remove the rectifier/
regulator cover.
3. Carefully noting the position of the electrical cables,
disconnect all four cables.
4. Remove the two nuts, washers and distance pieces
and remove the rectifier/regulator unit from the
fanshroud.
The unit will be fitted to either, the manifold side of
the shroud or above the starter motor.
5. Remove the cable clip securing the cable inside
the fanshroud.
6. Remove the six screws securing the stator and
remove it, gently easing the cable through the
fanshroud.
7. Remove the two bolts that are fitted through the
lower end of the fanshroud securing it to the sump.
8. Remove the self-lock bolts.
a. On older engines ease back the tab washers and
remove the bolts.
9. Lift off the housing.
Refitting the Fanshroud
Refitting is carried out in the reverse order and it is
recommended that new tabwashers are fitted and
correctly locked after the bolts have been torque
loaded to 43.5Nm (32.0lbf ft).
The tabwashers and bolts can be replaced with
the current self-locking setscrews which must be torque
loaded to 88.0Nm (65.0lbf ft).
CAUTION
If the sump has been removed, the procedure detailed
in "Replacing the Oil Sump" must be followed when
refitting the fanshroud to prevent the possibility of distorting
it resulting in excessive flywheel to shroud run-out. This is
particularly important on Build 16 engines.
