Fitting
1. When changing engines, transfer the
necessary components to the new
engine.
The chamfered side of the spacer (3) on
the crankshaft above the pump pulley
must face the engine.
The hub collar of the pulley (5) must face
downwards.
2. Put the four upper engine mount
isolators (22) in the engine bed (small
diameter end in the engine bed hole).
3. Check that the clutch tie down (10) is not
deformed (straighten if necessary) and
lower the engine into position. The
engine weighs 40.5 kg.
4. Inserting the spacers (22), washers (28,
21) and bolts (19) from below, fit the
engine mounts. The tightening torque for
the retaining nuts (20) is 110 Nm (80 ft/

The tightening torque for the bolt (9) is 67
Nm (50 ft/lb).
With the bolt (9) tightened, there should
be perceptible play between the clutch
and the clutch tie down (10) when the
clutch flange is turned by hand. Adjust/
twist the tie down and, using the nut (1),
tighten the bolt (2).
Ensure that the cable cannot be
damaged and secure it with a cable tie.
