2. The compressor needs to be cycled on a regular
basis. Run the compressor with air flowing,
weekly for 15-20 minutes. This will insure the
compressor rotors are coated with lubricant and
eliminate any moisture that may be present in the
compressor.
3. The oil should be changed after the first 30 hours
of system operation. After that, the oil should be
changed annually. There is a drain plug located at
the bottom of the oil cooler (see Oil Cooler Drain
Locations). The oil fill cap is located on top of the
sight gauge.
4. Change the compressor system spin-on oil filter
at the same time as the oil is changed.
5. Run the compressor for two minutes after chang-
ing the oil, then re-check the oil level and add oil
as necessary.
Do not overfill
.
6. Visually inspect the compressor oil system weekly
for signs of leaks.
7. A water strainer is installed on the oil/water cooler
inlet (see Oil Cooler Drain Locations). The water
strainer should be checked and cleaned weekly.
A plugged strainer will restrict cooling water and
cause overheating of the compressor system.
8. Check the air compressor PolyChain
drive for
damage or excessive wear semi-annually or more
frequently as dictated by the amount of use. Belt
tension may be checked by applying a 10-12 lb.
load to the belt, mid-span between drive and
driven sprocket. The belt should deflect .250 to
.313”.
Towing
When towing, disconnect the drive shaft that connects
the pump transmission’s rear output (coupling) shaft
to the vehicles differential. Failure to do so may result
in damage from lack of lubrication.
Poly Chain Replacement and Adjustment
9. The belt tension is set at the factory. No further
adjustment is required unless the belt is loosened
or removed to service other components.
When installing a synchronous belt, be sure it ten-
sioned adequately to prevent tooth jumping (rachet-
ing). Avoid extremely high tension which can reduce
belt life and possibly damage other drive components.
a. Remove the belt cover.
b. Loosen idler sprocket.
c. Turn the adjustment screw clockwise to
increse the belt tension. Adjust spring
height to 1-1/8 in.
d. For a new belt, set the tension to allow
1/4 - 5/16 inch of belt deflection when
10-12 lbs of force are applied at the cen-
ter of the greatest span. Do not over-
tighten the belt.
e. Apply loctite #242/243 (blue) to threads
and tighten the idler sprocket. Torque to
230 ft-lbs.
f.
Install the belt cover.
