8. Fitting the Drive Belt
NOTE: It is now most important that the motor pulley be aligned so that it is directly in line with the driven pulley (J).
8.1 A piece of 6mm rod is provided which is
used to align the pulleys as follows:
Hold the rod firmly in the ‘Vee’ of the upper,
driven pulley, then rotate the pulley and
rod together so that the other end of the
rod comes into contact with the vee of
the motor pulley.
The rod should come to rest perfectly
symmetrically in the motor pulley vee’.
Move the motor pulley in or out, as
appropriate, until this condition is met.
When satisfied, tighten the motor pulley
grub screw.
It is important that time is taken to ensure
this adjustment is correct, otherwise
premature failure of the drive belt could
occur.
8.2 Slip the drive belt over the top pulley, then
over the motor pulley.
NOTE:
The gap between the cover and top pulley is small
but the operation is possible by rotating the upper
pulley whilst easing the belt between the cover and
pulley rim.
8.3 Slacken off the two nuts, previously nipped
up to secure the Engine Mounting Plate in
position, then push down on the engine
so that tension is applied to the belt.
Tension is correct when there is approximately ½" total movement at the centre of the belt
run when using moderate thumb pressure.
The Support Plate should be as near parallel to the ground as possible when making this
adjustment.
8.4 When satisfied, secure the Engine Support Plate by tightening the nuts behind the Securing
Plate, ensuring the Support Plate remains perfectly parallel to the ground.
CAUTION: The nuts MUST tightened progressively.
8.4 Finally, lower the Outer Cover so that the channel formed on the rim of the cover engages
over the rim of the Inner Cover. Slide the cover down as far as possible and secure with the
screws provided.
