Pulley and Flywheel Alignment

The air compressor flywheel and engine pulley must be in-line (in
the same plane) within 1/16" (1.6 mm) to ensure belt retention within
flywheel belt grooves. To check alignment:
1. Ensure engine ON/OFF switch (C) is in the OFF Position.
. Allow the unit to cool.
3. Disconnect spark plug wire.
4. Drain air tank.
5. Remove outer belt cover.
6. Place a straightedge
(Q) against the outside
of the flywheel (R) and
the engine drive pulley
(S).
7. Measure the distance
between the edge of the
belt (T) and the straightedge at points A1 and A in Figure. The
difference between measurements should be no more than
1/16" (1.6 mm).
8. If the difference is greater than 1/16" (1.6 mm), loosen the
setscrew holding the engine drive pulley to the shaft and adjust
the pulley's position on the shaft until the A1 and A measure-
ments are within 1/16" (1.6 mm) of each other.
9. Tighten the engine drive pulley setscrew. Torque to 145–165 in.-lbs.
(16.4– 18.6 Nm).
10. Visually inspect the engine drive pulley to verify that it is
perpendicular to the drive motor shaft. Points B1 and B of Figure
should appear to be equal. If they are not, loosen the setscrew of
the engine drive pulley and equalize B1 and B, using care not to
disturb the belt alignment performed in Step 8.
