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 following steps:

Set the Auto/Off lever to "Off", unplug unit and relieve all air pressure from the

air tank.

Remove belt guard.

Place a straightedge against the

outside of the flywheel and the motor

drive pulley.

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" (1.6 mm).

If the difference is greater than 1/16" (1.6 mm) 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" (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. 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.

Retighten the motor drive pulley setscrew. Torque to 70-100 in-lbs

(7.9-11.3 Nm).

Reinstall belt guard.
