GENERAL SAFETY GUIDELINES

WARNING! PLEASE READ AND

FOLLOW THESE INSTRUCTIONS

TO AVOID PERSONAL INJURY OR DEATH:

When working on or around a vehicle, the following

guidelines should be observed AT ALL TIMES:

▲Park the vehicle on a level surface, apply the parking

brakes and always block the wheels. Always wear personal

protection equipment.

▲Stop the engine and remove the 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.

▲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.

▲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 a Bendix

DRM

dryer reservoir module, or a Bendix

™

dryer, be sure to drain the purge reservoir.

▲ Following the vehicle manufacturer's recommended

procedures, deactivate the electrical system in a manner

that safely removes all electrical power from the vehicle.

▲Never exceed manufacturer's recommended pressures.

▲Never connect or disconnect a hose or line containing

pressure; it may whip and/or cause hazardous airborne

dust and dirt particles. Wear eye protection. Slowly open

connections with care, and verify that no pressure is

present. Never remove a component or plug unless you are

certain all system pressure has been depleted.

▲ Use only genuine Bendix

components and kits. Replacement hardware, tubing, hose,

ﬁ ttings, wiring, etc. must be of equivalent size, type and

strength as original equipment and be designed speciﬁ cally

for such applications and systems.

▲Components with stripped threads or damaged parts should

be replaced rather than repaired. Do not attempt repairs

requiring machining or welding unless speciﬁ cally stated

and approved by the vehicle and component manufacturer.

▲Prior to returning the vehicle to service, make certain all

components and systems are restored to their proper

operating condition.

▲ For vehicles with Automatic Traction Control (ATC), the ATC

function must be disabled (ATC indicator lamp should be

ON) prior to performing any vehicle maintenance where

one or more wheels on a drive axle are lifted off the ground

and moving.

▲The power MUST be temporarily disconnected from the

radar sensor whenever any tests USING A DYNAMOMETER

are conducted on a vehicle equipped with a Bendix

Wingman

system.

▲You should consult the vehicle manufacturer's operating

and service manuals, and any related literature, in

conjunction with the Guidelines above.

DISASSEMBLY

1. Remove the discharge line from the discharge port of

the cylinder head and push the discharge line out of the

way.

2. Remove the governor or the air line from the governor

mounting pad on the head of the compressor. Remove

and discard the governor mounting gasket (9) if the

governor is mounted on the head.

3. Remove the inlet fitting or air strainer and discard the

gasket (10).

4. Remove the inlet and outlet water lines after draining

the radiator.

5. Remove and retain the four hex head cap screws from

the head. Tap the head with a mallet to break the gasket

seal and remove the head. Remove the head gasket (12).

6. Before disassembling the discharge valve mechanism,

measure and record the discharge valve travel (from

closed to completely open). If the measured discharge

valve travel DOES NOT EXCEED .032 inches,

the discharge valve stop need not be removed. It

is recommended that the cylinder head assembly

be replaced if the discharge valve stop requires

replacement. Using a 9/16" Allen

and o-ring assembly (1 & 2). (Refer to the unloader kit

instruction sheet included in this kit).

8. Insert the lugs of a spanner wrench into the holes of

the inlet valve stop (5) and remove the inlet valve stop

along with the inlet valve spring (6), inlet valve (15),

valve seat (7), inlet valve gasket (13), and unloader

spring (16). (NOTE: Reference Williams

face spanner #483.)

9. With a pair of needle nose pliers remove the unloader

piston and o-ring assembly (3 & 4).

10. Discard components 1 through 16.

CLEANING

Remove all carbon deposits, rust, and scale from all cavities

in the cylinder head. Use shop air to clear any loose particles

from these recesses. Scrape the gasket surfaces of the

head and the crankcase taking care not to allow foreign

material to fall into the cylinder.

INSPECTION

Inspect the inlet bushing and discharge valve stop for

excessive wear, nicks, and scratches. These surfaces

can be "dressed" with a lapping stone to improve their

condition.
