the motor up with the mark made
earlier on saddle.
2. Tighten two outside motor mounting
screws enough to hold the motor in
place for checking pulley and flywheel
alignment.
3. The belt should deflect 3/16” (4.8 mm)
at midway between the pulley and the
flywheel when a 5 pound (2.26 kg.)
weight is applied at the midway point.
4. When proper belt tension is achieved,
tighten all four motor mounting screws.
Torque to 20-25 ft-lbs
(27.1–33.9 Nm).
NOTICE:
Once the engine
pulley has been moved from its
factory set location, the grooves
of the flywheel and pulley must
be aligned to within 1/16”
(1.6 mm) to prevent excessive
belt wear. Verify the alignment by
performing the following
