BELT TENSION AND PULLEY ALIGNMENT
WARNING
I
unplug 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 (see A) of 1/2"
(13 mm) occurs by placing 5 lb (2.3 kg) of force (see 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 setscrews should be kept tight.
1.
Remove the belt guard.
2.
Loosen the motor mounting bolts.
3.
Shift the motor to the point where the correct deflection exists.
4.
Retighten the motor mounting bolts.
5.
Check to ensure that the tension remained correct.
6.
Reinstall the belt guard. All moving parts must be guarded.
