CHECKING AND ADJUSTING BELT
TENSION
Serious injury or damage may occur
if parts of the body or loose items get
caught in moving parts. Never oper-
ate the compressor outfit with the belt
guard removed. The belt guard should
only be removed after the spark plug
wire has been disconnected.
The drive belt should be kept in proper tension as a
loose belt will slip and wear faster. An over tightened
belt will place an excessive load on the engine and
compressor pump bearings causing premature failure.
The belt tension should be checked as follows:
1. Disconnect the spark plug wire and drain all air
pressure from the air tank.
2. Remove the belt guard.
3. Loosen all engine mounting hardware and slide
the engine either toward or away from the
compressor until correct belt tension is
achieved.
a.
On compressors equipped with standard
V-belts, each belt should deflect 1/4” at the
midway point between the engine pulley
and flywheel when a downard force of 8
pounds, is applied at the midway point.
Refer to Figure 4.

4. Hold the belt tension until the engine mount-
ing hardware can be tightened.
5. Ensure that the belts are centered on the
engine pulley and compressor flywheel.
NOTE
Once the engine has been moved
from its factory set location the engine
pulley must align to within
1/16 inch to the compressor flywheel.
6. Torque engine mounting bolts to 20-25 ft. lbs.
7. Reinstall the belt guard.
8. Connect the spark plug wire.
