ALIGNING THE PULLEY AND FLYWHEEL

The air compressor flywheel and motor pulley hub
must be in-line (in the same plane) within 1/16 in.
(1.6 mm) to assure belt retention within the flywheel
belt grooves. To check the alignment, perform the
following steps:
□
Turn the air compressor off, lock out the power
supply, and relieve all air pressure from the
air tank.
□
Remove the belt guard.
□
Place a straightedge (S) against the outside of the
flywheel (P) and the motor drive pulley hub (R).
□
Measure the distance between the edge of the
belt (Q) and the straightedge at points A1 and
A2 in the figure. The difference the between
measurements should be no more than 1/16 in.
(1.6 mm).
□
If the difference is greater than 1/16 in.
(1.6 mm), loosen the set screws holding the
motor drive pulley (R) to the shaft and adjust the
pulley position on the shaft until the A1 and A2
measurements are within 1/16 in. (1.6 mm) of
each other.
□
Tighten the motor drive pulley set screws.
□
Visually inspect the motor drive pulley to verify
that it is perpendicular to the drive motor shaft.
Points B1 and B2 of the figure should appear to
be equal. If they are not, loosen the set screws
of the motor drive pulley and equalize B1 and
B2, using care not to disturb the belt alignment
previously performed.
□
Retighten the motor drive pulley set screws.
Torque to 145–165 in. lbs.
(16.4–20.3 Nm).
□
Reinstall the belt guard.
