BELT TENSION AND PULLEY ALIGNMENT

the compressor and relieve all air pressure from the system before
performing any service on the air compressor.
NOTE: Drive belt tensioning and pulley alignment are done at the
same time. They are discussed separately for clarity.
ADJUSTING DRIVE BELT TENSION
Proper belt tension and pulley alignment must be maintained for maximum drive
efficiency and belt life. The correct tension exists if a deflection (A) of 1/4"
(6.5 mm) occurs by placing 10 lb (4.5 kg) of force (B) midway between the motor
pulley and the pump flywheel (See Fig. 8). This deflection can be adjusted by the
following procedure. The pulley should be carefully aligned with the flywheel, and
all set screws should be kept tight. A spring loaded belt tensioning gauge can be
used to measure this.
1. Remove the outer belt guard.
2. Loosen the motor mounting bolts.
Shift the motor to the point where the correct deflection exists.
3.
4. Re-tighten the motor mounting bolts.
5. Check to ensure that the tension remained correct.
6. Reinstall the outer belt guard. All moving parts must be guarded.
MAINTENANCE
To avoid personal injury, always shut off and unplug
