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" to
prevent excessive belt wear. Verify the alignment by performing the follow-
ing 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" to prevent
excessive belt wear.
The air compressor flywheel and motor pulley must be in-line (in the same plane)
within 1/16" to assure belt retention within flywheel 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 against the outside of the flywheel and the motor
drive pulley.
4.
Measure the distance between
the edge of the belt and the
straightedge at points A1 and A2
in figure. The difference between
measurements should be no more
than 1/16".
5.
If the difference is greater than 1/16"
loosen the set screw holding the motor drive pulley to the shaft and adjust
the pulley's position on the shaft until the A1 and A2 measurements are
within 1/16" of each other.
6.
Tighten the motor drive pulley set screw. See Parts manual for torque
specifications.
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. See Parts manual for torque
specifications.
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. Retighten if
necessary. See Parts manual for torque specifications
