7. With the pump secure, roll the belt over the flywheel and the
pulley.
8. Check the belt tension again. See Step 7 in Checking Belt
Tension under Maintenance.
9. When tension is correct, torque four pump mounting nuts (Torque
to 6–8 ft.- lbs./8.1–10.8 Nm), stiffener bracket bolt (Torque to
10–12 ft.- lbs./13.5–16.3 Nm), and replace belt cover.

Pulley and Fly wheel Alignment

The air compressor flywheel and motor 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 On/Off switch is in the OFF position.
2. Allow the unit to cool.
3. Remove air compressor plug from outlet.
4. Drain air tank.
5. Remove outer belt cover.
6. Place a straightedge (T)
against the outside of
the flywheel (U) and the
motor drive pulley (V).
7. Measure the distance
between the edge of
the belt (N) and the
straightedge at points A1 and A2 in Figure. The difference between
mea sure ments 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 motor drive pulley to the shaft and adjust
the pulley's position on the shaft until the A1 and A2 mea sure-
ments are within 1/16" (1.6 mm) of each other.
9. Tighten the motor drive pulley setscrew. Torque to 145–165 in.-lbs.
(16.4– 18.6 Nm).
10. Visually inspect the motor drive pulley to verify that it is perpendicular
to the drive motor shaft. Points B1 and B2 of Figure should appear
to be equal. If they are not, loos en the setscrew of the motor drive
pulley and equal ize B1 and B2, using care not to disturb the belt
align ment per formed in Step 8.
11. Retighten the motor drive pulley set screw. Torque to
145– 165 in.-lbs. (16.4–18.6 Nm).
12. Reinstall belt guard.
