AIR INDUCTION

The Bendix

® 

360cc Single Cylinder Compressors is 

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:  Maintenance Schedule and 

Usage Guidelines in the troubleshooting section (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 Bendix

®

 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 Bendix

®

 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, 

chafi 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)
