SAFE MAINTENANCE PRACTICES
WARNING! PLEASE READ AND FOLLOW
THESE INSTRUCTIONS TO AVOID
PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following general
precautions should be observed at all times:
1. Park the vehicle on a level surface, apply the parking
brakes, and always block the wheels. Always wear safety
glasses. Where specifically directed, the parking brakes
may have to be released, and/or spring brakes caged,
and this will require that the vehicle be prevented from
moving by other means for the duration of these tests/
procedures.
2. Stop the engine and remove ignition key when working
under or around the vehicle. When working in the engine
compartment, the engine should be shut off and the
ignition key should be removed. Where circumstances
require that the engine be in operation, EXTREME
CAUTION should be used to prevent personal injury
resulting from contact with moving, rotating, leaking,
heated or electrically charged components.
3. Do not attempt to install, remove, disassemble or
assemble a component until you have read and thoroughly
understand the recommended procedures. Use only the
proper tools and observe all precautions pertaining to use
of those tools.
4. If the work is being performed on the vehicle's air brake
system, or any auxiliary pressurized air systems, make
certain to drain the air pressure from all reservoirs
before beginning ANY work on the vehicle. If the vehicle
is equipped with an AD-IS
reservoir module, be sure to drain the purge reservoir.
5. Following the vehicle manufacturer's recommended
procedures, deactivate the electrical system in a
manner that safely removes all electrical power from the
vehicle.
6. Never exceed manufacturer's recommended pressures.
7. Never connect or disconnect a hose or line containing
pressure; it may whip. Never remove a component or
plug unless you are certain all system pressure has been
depleted.
8. Use only genuine Bendix
and kits. Replacement hardware, tubing, hose, fittings,
etc. must be of equivalent size, type and strength as
original equipment and be designed specifically for such
applications and systems.
9. Components with stripped threads or damaged parts
should be replaced rather than repaired. Do not attempt
repairs requiring machining or welding unless specifically
stated and approved by the vehicle and component
manufacturer.
10. Prior to returning the vehicle to service, make certain all
components and systems are restored to their proper
operating condition.

These instructions are included along with the various
sub-kits that are necessary to install the compressor on
the vehicle. Note: Not all components supplied (e.g. pipe
plugs, etc.) will necessarily be used in all installations.
Typical kits supplied with the compressor are a flange
gasket(s) and/or o-ring kit, cylinder head gaskets kit,
and pipe plugs kit.

rpm, while Bendix
up to 2400 rpm. Both compressors are rated to operate
in temperature ranges from -40
maintained to spec. Factors that may affect the compressor
performance include:
1. Lubrication oil quality and quantity. For example,
it is important to maintain low levels of soot in the
lubrication oil; sufficient oil supply; as well as sufficient
return drainage to the engine (to prevent sump overfull
conditions).
Check the condition of the oil supply line, making certain
no kinks or obstructions exist. Replace as necessary.
Oil return lines to the engine should not be restricted
- check for excessive bends, kinks, and restrictions
since oil contaminants could potentially plug the line.
The minimum recommended oil return line size is
O.D. tubing or equivalent I.D. (
lines must constantly descend from the compressor to
the engine crankcase. Make certain oil drain passages
in the compressor and mating engine surfaces are
unobstructed and aligned. Special care must be taken
when sealants are used with, or instead of, gaskets.
Check the engine oil pressure with a test gauge and
compare the reading to the engine specifications.
Minimum oil supply line size is
