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. Verify the
alignment by performing the following
Pulley and Flywheel - Alignment.
MOTOR PULLEY/FLYWHEEL
ALIGNMENT
NOTE: Once the motor 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 motor
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 follow-
ing 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 against the
outside of the flywheel and the
motor drive pulley.
4. Measure the distance between the
edge of the belt and the straight-
edge at points A1 and A2 in figure.
The difference between measure-
ments should be no more than
1/16" (1.6 mm).
5. If the difference is greater than
1/16" (1.6 mm) loosen the set
screw holding the motor drive pul-
ley to the shaft and adjust the pul-
ley's position on the shaft until the
A1 and A2 measurements are with-
in 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 perpen-
dicular 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 pul-
ley setscrew. Torque to 145-165
in- lbs.
9. Reinstall belt guard.
AIR COMPRESSOR PUMP
INTAkE AND ExHAUST VALVES
Once a year have a Trained Service
Technician check the air compressor
pump intake and exhaust valves.
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
fittings and connections/piping.
3. Correct any leaks found.
IMPORTANT: Even minor leaks can
cause the air compressor to overwork,
resulting in premature breakdown or
inadequate performance.
AIR COMPRESSOR HEAD
BOLTS - TORqUING
The air compressor pump head bolts
should be kept properly torqued. Check
the torques of the head bolts after the
first five hours of operation. Torque to
32.5 ft.-lbs.
