Belt - Replacement
(Refer to the Parts Manual for
replacement belt part number.)
Serious injury or
damage may
occur if parts of the body or loose
items get caught in moving parts.
Never operate the outfit with the
belt guard removed. The belt
guard should be removed only
when the air compressor power is
disconnected.
1.
Turn air compressor off, lock out
the power supply, and relieve all
air pressure from the air tank.
2. Remove the belt guard.
3. Mark pump position on saddle.
4. Loosen the motor mounting
screws and slide the motor
toward the air compressor.
5. Remove the belt and replace
with a new one.
6. See the "Adjust Belt Tension"
before tightening motor mounting
screws.
Adjusting Belt Tension
1. Slide motor into original position,
line the motor up with the mark
made earlier on saddle.
2. Tighten two outside motor
mounting screws enough to hold
the motor in place for checking
pulley and flywheel alignment.
3. The belt should deflect 3/16" at
midway between the pulley and
the flywheel when a 5-10 pound
weight is applied at the midway
point.
3. When proper belt tension is
achieved, tighten all four motor
mounting screws. See Parts
manual for torque specifications.
NOTE: Once the engine pulley has
been moved from its factory set
location, the grooves of the
flywheel and pulley must be
aligned to within 1/16" to prevent
excessive belt wear. Verify the
alignment by performing the
following Pulley and Flywheel -
Alignment.
