Motor Pulley/Flywheel
Alignment (Figure 8)
The air compressor ywheel and motor pulley
must be in-line (in the same plane) within
1/16" (1.6 mm) to assure belt retention
within ywheel belt grooves. To check
alignment, perform the following steps:
1. Turn air compressor off, lock out
the power supply, and relieve all air
pressure from the air tank.
2. Remove belt guard.
3. Place a straightedge (S) against the
outside of the ywheel (P) and the
motor drive pulley (R).
4. Measure the distance between the edge
of the belt (Q) and the straightedge
at points A1 and A2 in gure. The
difference between measurements
should be no more than 1/16" (1.6 mm).

Air Compressor Pump
Intake and Exhaust Valves
Once a year bring the compressor to a
service center. and have a Trained Service
Technician check the air compressor pump
intake and exhaust valves.

5. If the difference is greater than 1/16"
(1.6 mm) loosen the set screw holding
the motor drive pulley (R) to the shaft
and adjust the pulley's position on the
shaft until the A1 and A2 measurements
are within 1/16" (1.6 mm) of each other.
6. Tighten the motor drive pulley set screw.
7. 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, loosen the setscrew of the
motor drive pulley and equalize B1 and
B2, using care not to disturb the belt
alignment performed in step 2.
8. Retighten the motor drive pulley
setscrew. Torque to 145–165 in lbs
(16.4–20.3 Nm).
9. Reinstall belt guard.

INSPECT AIR LINES AND
FITTINGS FOR LEAKS
1. Turn air compressor off, lock out
the power supply, and relieve all air
pressure from the air tank.
2. Apply a soap solution to all air line
ttings and connections/piping.
3. Correct any leaks found.
NOTICE: Even minor leaks can
cause the air compressor to
overwork, resulting in premature
breakdown or inadequate
performance.
