position.
2. Allow the unit to cool.

the engine in place for
checking pulley and
flywheel alignment.
7. The belt should deflect
1/2” (13mm) at mid-
way between the pul-
ley and the
flywheel when a 5
pound (2.26kg.)
weight is applied at the
midway point.
8. When proper belt tension is achieved, tighten all four engine
mounting screws. Torque to 15-22 ft-lbs
(20.3–29.8 Nm).
9. Reconnect spark plug wire.
Pulley and Fly wheel Alignment
NOTE: 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.
The air compressor flywheel and engine pulley must be in-line
(in the same plane) within 1/16” (1.6 mm) to assure belt retention
within flywheel belt grooves. To check alignment, perform the fol-
lowing steps:
1. Ensure engine
START/RUN/OFF
switch (C) is in the
OFF Position.
2. Allow the unit to cool.
3. Disconnect spark
plug wire.
