7. While holding the Adjust Nut, retighten the Jam Nut.
8. Retighten the Engine Bolts.
9. Check the alignment of the Clutch with the Drive Pulley by placing a
Straight Edge across the face of the Drive Pulley (Figure 18). The Straight
Edge should be parallel with the Belt. If adjustment is necessary, correct
the alignment as follows:
a) Remove the two Set Screws in the Drive Pulley Hub with a 5/32" Allen
Wrench and set them aside.
b) Using a Straight Edge, align the Drive Pulley (Figure 18) to be parallel with
the Belt, by moving the Drive Pulley in or out on the Rotor Shaft (Figure 15
on page 18).
NOTE: If the Drive Pulley cannot be moved in or out enough to obtain parallelism,
you will have to swap the shims behind or in front of the Drive Pulley. This will
necessitate removing the Belt and the Snap Ring on the Rotor Shaft (Figure 15 on
page 18), swapping the shims and reinstalling the Drive Pulley, Snap Ring and
Belt. Once you have obtained parallelism, continue with step c).
c) Apply Loctite ® 243 to the threads of the Set Screws and reinsert them into
the Drive Pulley Hub.
d) Tighten the Set Screws while maintaining the parallelism between the
Drive Pulley face and the Belt.
e) Recheck the alignment after tightening the Set Screws.
10. Reinstall the Belt Guard.
NOTE: Check and re-tighten the Drive Belt, if necessary, after an initial break-in
period of one (1) hour.
