AIR INDUCTION

The 360cc Single Cylinder Compressors are only permitted
to be naturally aspirated – use of engine turbocharger as
an air source is not permitted.

PREVENTATIVE MAINTENANCE

Regularly scheduled maintenance is the single most
important factor in maintaining the air brake charging
system. Refer to Table A in the Troubleshooting section on
page A-3, for a guide to various considerations that must be
given to maintenance of the compressor and other related
charging system components.

Important Note: Review the warranty policy before
performing any intrusive maintenance procedures. An
extended warranty may be voided if intrusive maintenance
is performed during this period.

EVERY 6 MONTHS, 1800 OPERATING HOURS
OR AFTER EACH 50,000, MILES WHICHEVER
OCCURS FIRST, PERFORM THE FOLLOWING
INSPECTIONS AND TESTS.

AIR INDUCTION

A supply of clean air is one of the single most important
factors in compressor preventive maintenance. Since the
air supply for 360cc Single Cylinder Compressor and engine
is the engine air cleaner, periodic maintenance of the engine
air

fi lter is necessary.

Inspect the compressor air induction system each time
engine air cleaner maintenance is performed.

1. Inspect the intake hose adapters for physical damage.

Make certain to check the adapters at both ends of the
intake hose or tubing.

2. Inspect the intake hose clamps and tighten them if

needed.

3. Inspect the intake hose or line for signs of drying, cracking,

cha

fi ng and ruptures and replace if necessary.

4. Inspect the compressor’s cast inlet tube for physical

damage.

COMPRESSOR COOLING

Inspect the compressor discharge port, inlet cavity and
discharge line for evidence of restrictions and carbon
buildup. If more than 1/16" of carbon is found, thoroughly
clean or replace the affected parts. In some cases, carbon
buildup indicates inadequate cooling. Closely inspect the
compressor cooling system. Check all compressor coolant
lines for kinks and restrictions to

fl ow. Minimum coolant line

size is 3/8" I.D. Check coolant lines for internal clogging
from rust scale. If coolant lines appear suspicious, check
the coolant

fl ow and compare to the tabulated technical

data present in the back of this manual.

LUBRICATION

The compressor utilizes an internal oil feed design. Check
the exterior of the compressor (i.e. around the mounting
face) for the presence of oil seepage and refer to the
Troubleshooting section for appropriate tests and corrective
action. Refer to the tabulated technical data in the back of
this manual for oil pressure minimum values.

OIL PASSING

All reciprocating compressors pass a minimal amount of oil.
Air dyers will remove the majority of oil before it can enter
the air brake system. For particularly oil sensitive systems,
the Bendix PuraGuard system can be used in conjunction
with a Bendix

®

air dryer.

If compressor oil passing is suspected, refer to the
Troubleshooting section (starting on page A-1) for the
symptoms and corrective action to be taken. In addition,
