Maintenance (continued)
MOTOR PULLEY/FLYWHEEL ALIGNMENT
The air compressor flywheel and motor pulley 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 front belt guard.
□
Place a straightedge (4) against the outside of
the flywheel (1) and the motor drive pulley (3).
□
Measure the distance between the edge of the
belt (2) and the straightedge at points A1 and A2.
The difference 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 screw holding the
motor drive pulley (3) to the shaft and adjust the
pulley's 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 screw.
□
Visually inspect the motor drive pulley to verify
that it is perpendicular to the drive motor shaft.
The points (B1 and B2) should appear to be
equal. If they are not, loosen the set screw of
the motor drive pulley and equalize B1 and B2,
using care not to disturb the belt alignment
performed previously.
□
Retighten the motor drive pulley set screw.
Torque to 145-180 in. - lbs. (16.4-20.3 Nm).
□
Reinstall the front belt guard.
