Use only genuine Bendix

®

replacement parts,

components and kits. Replacement hardware,
tubing, hose,

fi ttings, etc. must be of equivalent

size, type and strength as original equipment and
be designed speci

fi cally 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.

11. For vehicles with Antilock 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.

REMOVAL

In many instances it may not be necessary to remove the
compressor from the vehicle when installing the various
maintenance kits and service parts. The maintenance
technician must assess the installation and determine the
correct course of action. These instructions are general
and are intended to be a guide. In some cases additional
preparations and precautions are necessary. In all cases
follow the instructions contained in the vehicle maintenance
manual in lieu of the instructions, precautions and procedures
presented in this manual.

1. Block the wheels of the vehicle and drain the air pressure

from all the reservoirs in the system.

2. Drain the engine cooling system and the cylinder head

of the compressor. Identify and disconnect all air, water
and oil lines leading to the compressor.

3. Remove as much road dirt and grease from the exterior

of the compressor as possible.

4. Remove the discharge

fi tting, if applicable, and note their

position on the compressor to aid in reassembly.

5. Remove any supporting bracketing attached to the

compressor and note their positions on the compressor
to aid in reassembly.

6. Remove the 6 mounting bolts that retain the compressor

to the side of the engine block. Note the position of the
6 mounting bolts. Two of the 6 bolts are shorter and
must be installed in their original locations. Remove the
compressor from the vehicle.

7. Inspect drive gear and associated drive parts for visible

wear or damage. If the compressor drive gear is worn

or damaged, the compressor must be replaced.
Refer to the Engine Manufacturers service manual
to address the associated engine drive parts.

8. If the compressor is being replaced stop here and

proceed to “Installing the Compressor” at the end
of the assembly procedure. (Note: Replacement
compressors come with the drive gear pre-
assembled on the compressor.)

PREPARATION FOR DISASSEMBLY

Refer to Figure 8 during the entire disassembly and
assembly procedure.

Place a clean rag over the openings that expose the
gear and crankshaft / connecting rod assembly. No
contamination is permitted in these areas.

Remove the balance of the road dirt and grease from the
exterior of the compressor with a cleaning solvent. If the
rear end cover (8) is being removed from the compressor
being worked on, mark it and the 2 cap screws (7) in
relation to the crankcase. It is also recommended to
mark the relationship of the cylinder head (15), cooling
plate (14), valve plate assembly (13), and crankcase.

A convenient method to indicate the above relationships
is to use a metal scribe to mark the parts with numbers
or lines. Do not use marking methods such as chalk that
can be wiped off or obliterated during rebuilding.

Prior to disassembly, make certain that the appropriate
kits are available.

CYLINDER HEAD, COOLING PLATE & VALVE
PLATE ASSEMBLY

1. Remove the washer (3) and discharge safety valve

(2) from the cylinder head (15).

2. Remove the four hex head bolts (1) from the cylinder

head (15).

3. Gently tap the cylinder head (15), cooling plate (14)

and valve plate assembly (13) with a soft mallet
to break the gasket seal between the valve plate
assembly (13) and the crankcase. Lift the cylinder
head (15) with cooling plate (14) and valve plate
assembly (13) off the crankcase.

4. Remove the metal inlet reed valve/gasket (5).

5. Remove the crankcase o-ring (12) from a countersunk

hole on the crankcase (11) deck.

6. Gently tap the cylinder head (15), cooling plate (14)

and valve plate assembly (13) with a soft mallet to
break the gasket seals. Then separate the cylinder
head (15) from the cooling plate (14) and valve plate
assembly (13), and remove and discard the two head
gaskets (4) between them.
