ADJUSTING BELT TENSION
1. Slide motor into original position, line 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 align-
ment.
3. The belt should deflect 1/4" (6.5 mm) at midway between
the pulley and the flywheel when a 10 pound (4.5 kg.) weight
is applied at the mid-
way point.
4. When proper belt
tension is achieved,
tighten motor mount-
ing screws. Torque to
20-25 ft-lbs
(27.1-33.9 Nm).
NOTICE: Once the motor 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 Motor Pulley/
Flywheel - Alignment.
