GENERAL INFORMATION
You have purchased a complete compressor outfit consisting of an air compressor, ASME approved air tank,
gasoline engine, and associated controls and instruments. The compressor outfit you have selected is a
two stage stationary outfit.
Your new compressor can be used for operating paint
sprayers, air tools, grease guns, air brushes, caulking
guns, and sand blasters, spraying weed killer and
insecticides, etc. An air pressure regulator may be
necessary for some of these
DESCRIPTION OF OPERATION
The gasoline engine uses a pulley and drive belt to
drive the compressor flywheel. The flywheel turns the
compressor crankshaft causing the up and down movement of the pistons in the cylinder; this up and down
movement draws and compresses the air.
On the down stroke of the piston, air is drawn in through
the air intake. The exhaust valves remain closed. On
the up stroke of the piston, both the valves are closed
and air is compressed in the cylinder. As pressure
builds in the cylinder the exhaust valve opens and the
compressed air is forced out of the cylinder through
the check valve and into the air tank. This process
continues until the air pressure reaches maximum tank
pressure.
Working air pressure becomes available when the compressor has raised the tank pressure above that required at the air discharge valve. The air intake must
be kept clear of all obstructions which could interfere
with air delivery to the compressor.
All gasoline compressor outfits are continuously running outfits controlled by tank pressure. At maximum
applications. Refer to Figure 1 for a photograph of
the compressor and to identify the major components
of the compressor.
A regularly scheduled program of preventive maintenance is necessary to insure the long life that has been
designed into your DeVilbiss compressor outfit. This
instruction manual, along with regular maintenance
will maintain your compressor outfit in good working
order. Before operating or performing any maintenance
on your outfit, refer to these publications.
tank pressure the unloader valve exhausts air to atmosphere (blowoff); tank pressure closes the check
valve retaining air pressure inside the tank. When tank
pressure drops to a pre-determined pressure, the
unloader valve closes, and air pressure opens the
check valve allowing compressed air into the tank. As
maximum tank pressure is reached, if the unloader
valve malfunctions and compressed air is not exhausted at or near its blowoff setting, the air tank safety
valve will protect the air tank against high pressure by
popping at its factory set pressure. The safety valve
popping pressure is slightly higher than the unloader
valve blowoff pressure.
This compressor outfit is equipped with a gas saving
throttle control device. When maximum tank pressure
is reached and the unloader valve opens the throttle
control is also activated, The throttle control holds the
engine at a factory set idling speed until air pressure
in the tank drops to reset or minimum tank pressure.
At reset pressure when the unloader valve closes the
throttle control is reactivated and the engine accelerates to full throttle.

INSTALLATION
PRE-INSTALLATION INSPECTION
NOTE
Each air compressor outfit is carefully checked before shipment. With
improper handling, damage may
result in transit and cause problems
in compressor operation; a bent
crankshaft, etc.
Immediately on equipment arrival, check for both concealed and visible damages to avoid expenses being
incurred to correct such problems. This should be done
regardless of any visible signs of damage to the shipping container. Report any damages to carrier and arrange for inspection of goods immediately.
VIBRATION MOUNTING KIT
(Stationary Compressor Outfits)
Bolting legs to a stiff surface can
cause tank rupture resulting in serious
injury or damage. Do not permanently
mount compressor to any surface with-
out using the vibration mount kit.
Portable compressor outfits may be permanently
mounted in one location such as a truck bed, if desired. A vibration mount kit is included with the outfit
for this purpose.
2. Insert the vibration mounts in the mounting holes.
Place a flat washer under the mounting surface
and secure each mount with a lockwasher and
nut. See Figure 3.
Figure 3 - Installation of Vibration Mounting Kit
3. Set the outfit on top of the vibration mounts
(the exposed threaded ends) and secure
each mount to the air tank legs with lock
washer and nut.
LOCATION OF THE COMPRESSOR
OUTFIT
1. In order to maintain adequate ventilation for
compressor cooling and to avoid contact with
pick-up truck bed, always mount the outfit at
least 8 inches from any vertical wall. Using the
holes in the air tank support legs as a guide,
mark and drill four 5/16 inch diameter holes in
the mounting surface.
To prevent excessive vibration which
may cause tank rupture or explosion,
never remove the engine stiffener bar
or increase the engine RPM. Make
sure the engine bolts and stiffener bar
nuts are tight. Do not operate the outfit
if the rubber feet are not attached.
PAGE 8
Engine exhaust contains toxic carbon
monoxide. Operate the engine in a well
ventilated area only. If inhaled, it can
cause dizziness, unconsciousness and
possibly death.
The air compressor outfit should be located as close
as possible to the point where the compressed air is
to be used. The area selected should be dry, clean,
cool, and well ventilated. Make certain that the outfit
is mounted level on a solid foundation so no strain is
imposed on the support feet or base. Keep the outfit
away from areas which have dirt, vapor, and volatile
fumes in the atmosphere which may clog and gum
the intake filter and valves causing inefficient
operation. Where this not practical a remote air
intake is recommended.
Page 9
NOTE
Where a remote air intake is used, enlarge
the side of the air intake piping by one pipe
size for each 10 feet of length.
Pipe thread sealant must be used on all threads, and
all joints are to be made up tight, since small leaks in
the piping system are the largest single cause of high
operating costs.
Stationary outfits must be bolted or lagged to the floor
to prevent movement. When lagging down, leave a minimum of 1/8 inch between the bolt and support feet.
The use of vibration pads at each support foot is required to eliminate the possibility of tank rupture.
The flywheel side of the outfit should be placed toward
the wall and protected with a totally enclosed belt
guard. In no case should the flywheel be closer than
12 to 18 inches from the wall or other obstruction that
will interfere with the flow of air through the fan blade
flywheel. See Table 1 for recommended distances. The
area should allow space on all sides for air circulation
and for ease of normal maintenance.
The compressor outfit must not be operated in any confined area where
heat from the outfit can not readily escape. Damage to the outfit may result.
The compressor crankcase and head are designed
with fins which allow for proper cooling. Clean or blow
off the fins and any other parts of the compressor outfit that collect dust or dirt. A clean compressor runs
cooler and provides longer service. Do not place rags,
containers, or other material in or against the belt guard
which will obstruct ventilation openings necessary for
proper compressor operating temperatures.
All piping should be sloped to an accessible drain
point and all outlets should be taken from the top of
the main distribution air line so that moisture cannot
enter the outlet.
The main distribution air line should not be smaller
than the compressor air discharge valve outlet. A
smaller line will restrict the flow of air. For long air
lines, refer to Table 2, Pipe Sizes for Compressed
Air Lines, for recommended pipe sizes. It is recommended that a flexible coupling be installed between
the air discharge valve outlet and main air distribution line to allow for vibration.
To remove entrained dirt, oil and water, install separator in the main distribution line, a sufficient distance
from the compressor. This will allow the air to cool to
room temperature before passing through the separator.
Additional separators or filter may be used depending on the application.
NOTE
For underground installation, bury air
lines below the frost line and avoid
pockets where condensation can
gather and freeze. Apply pressure before underground lines are covered
to make sure all pipe joints are free
from leaks.
AIR LINE PIPING
(STATIONARY COMPRESSOR OUTFITS)
The use of plastic pipe, soldered joint,
or failure to insure system capability
of flex joints and flexible hose can
result in mechanical failure, property
damage, and serious injury.
Plastic or PVC pipe is not designed for
use with compressed air. Regardless
of its indicated pressure rating, plastic
pipe can burst from air pressure. Use
only metal pipe for air distribution lines.
A typical compressed air distribution system as shown
in Figure 4, page 10 should be of sufficient pipe size
to keep the pressure drop between the supply and
point of use to a minimum. All pipes and fittings used
must be certified safe for the pressures involved.

OPERATION
Operator Controls
The unloader valve for the operation of the gasoline
compressor outfit is located between the compressor
pump and gasoline engine. The air discharge valve
can be located on the end of the air tank. The safety
valve and pressure gauge are attached to the tank
below the unloader. See page 7.
Unloader Valve
Pressure loads beyond the design limits
may cause tank rupture or explosion. Do
not attempt to adjust, remove, or defeat
the unloader valve, or change and modify
any pressure control device. If replacement is necessary, the same rated valve
must be used.
The unloader valve, Figure 6, is controlled by tank pressure. Compressors with unloaders run continuously
and maintain air pressure within set limits. At maximum tank pressure the unloader valve opens and the
compressed air is exhausted to atmosphere. This
prevents the compressor from continually building more
pressure if air is not needed. When the tank pressure
drops to a predetermined minimum pressure, the
unloader valve closes and the compressor again builds
up the tank pressure. Pressure continues to build until maximum tank pressure is achieved. The cycle
then repeats itself.
The unloader is used because frequent start-ups and
stops are impractical with a gasoline engine. The
unloader valve is preset at the factory. Never attempt
to make adjustments to the unloader valve.
The toggle lever on the front of the unloader valve should
be pulled out or in the horizontal position when starting up the compressor. This prevents the compressor
from starting under load. Once the engine has reached
full throttle, the lever should be pushed to the side,
returning it to its original position to allow the compressor pump to build pressure in the air tank.
Toggle
Lever
Figure 6. Unloader Valve
PAGE 11
Page 12
The unloader then reactivates the throttle control
and accelerates the engine to full throttle.
Over-pressurization of the air tank
may cause tank rupture or explosion.
The air tank is protected from overpressurization by a safety valve. Do
not eliminate, make adjustments or
substitutions to this device. Occasionally pull the ring on the safety valve
to make sure it operates freely. If it
doesn’t, the safety valve must be
replaced. Innercooler safety valves
used on two stage outfits must be
similarly checked.
The safety valve, Figure 7, is set at the factory to be
pressure approximately 15 pounds higher than the
rated pressure of the outfit. If the unloader valve malfunctions and does not exhaust compressed air automatically at maximum tank pressure the safety valve
will protect the air tank against excessive air pressure
by popping off at its preset pressure.
Two stage compressors with unloader controls will have
a safety valve on the intercooler, set 50 to 55 pounds.
The purpose of this safety valve is to prevent the full
tank pressure building up in the large, low pressure
cylinder or intercooler.
THROTTLE CONTROL
A gas saving throttle control has been incorporated
on some compressor outfits. During normal operation,
as maximum tank pressure is obtained, the unloader
exhausts compressed air and activates the throttle
control of the engine. The throttle control holds the
engine at a factory set idling speed until air pressure
in the tank drops to reset or minimum tank pressure.
ADDITIONAL REGULATORS AND
CONTROLS
Since the air tank pressure is usually greater than
that which is needed, a separate regulator is usually
employed to control the air pressure ahead of any
individual air driven device.
The gasoline engine and air compressor
pumps on all compressor outfits are
shipped without oil. Do not attempt to
operate for any reason without first adding oil to the engine and compressor
pump crankcase. Serious damage can
result from even very limited operation
unless filled with oil and broken in
correctly. Make sure to closely follow the
initial startup procedures.
NOTE
The compressor outfit should be placed
on a level surface in a dry, clean, well
ventilated, area. Do not place any material on or against the belt guard. This
blocks ventilator openings necessary for
proper compressor cooling.
1. Remove the oil fill plugs on the gasoline engine
and air compressor pump and slowly add oil
until the units are full. Refer to the “Gasoline
Engine Owners Manual” for recommended oils
and fill capacities for the engine. The compressor pump holds approximately 60 fluid oz..

BREAK-IN PROCEDURES
Perform steps 1-8 of the Daily Startup Procedures.
Open the air discharge valve.
DAILY STARTUP PROCEDURES
4. Check the engine fuel tank level. Add fuel if
necessary.
Before starting the compressor outfit, check the
following:
5. Close the air discharge valve.
6. Set the toggle lever of the unloader valve in
the vertical position to relieve compressor
head pressure.
7. Move the control lever or choke lever to the
CHOKE position.
8. Turn the engine lever or key switch to the
ON position.
NOTE
If the engine is warm or the air temperature is high, move the control
lever or choke lever away from the
CHOKE position as soon as the engine
starts.
Perform the following checks before starting the
compressor outfit.
1. Ensure that nothing is blocking the belt
guard air openings.
2. Pull the ring on the safety valve to make
sure the valve moves freely and smoothly.
3. Check the engine and compressor oil levels.
Add oil if necessary.
Gasoline is extremely flammable and
explosive. Refuel in a well ventilated
area with engine stopped. Allow engine
to cool before refueling.
Do not smoke or allow flames or sparks in
the area where the engine is refueled or
where gasoline is stored.
Do not overfill the tank and make sure
the filler cap is securely closed after
refueling. Be careful not to spill fuel
when refueling. Fuel vapor or spilled
fuel may ignite. If any fuel is spilled,
make sure the area is dry before
starting the engine.
9. Start the compressor outfit by pulling the
starter handle or by depressing the starter
button. Return the toggle lever on the unloader
valve to the horizontal position and allow
outfit run for 10 minutes without building any
pressure. Check that the unloader exhausts
air at maximum tank pressure.
If these break-in procedures are not
followed, premature pump failure may
result and void your warranty.
10.Check the following:
a. Make sure all controls are operating
correctly. Refer to the "Operator Controls"
section of this manual. A separate
gasoline engine instruction manual is
provided detailing engine operation.
b. Check all air lines, fittings and pipes for
leaks. Even minor leaks can cause the
compressor to overwork resulting in
premature breakdown or unsatisfactory
performance.
PAGE 13
Page 14
c. Check for excessive vibration and noise.
Correct any defects found.
2. Turn the engine lever or key switch to the OFF
position.
d. Check for oil leaks. Correct any leaks
found.
SHUT DOWN PROCEDURES
To stop the engine in an emergency, turn the engine
ON/OFF lever or key switch to the OFF position. Under normal conditions, use the following procedures.
1. Allow the tank pressure to build to maximum
and the engine to throttle down to idle speed.
MAINTENANCE
To ensure efficient operation and longer life of the air
compressor outfit a routine maintenance schedule
should be prepared and followed. The following routine maintenance schedule is geared to an outfit in a
normal working environment operating on a daily basis. If necessary , the schedule should be modified to
suit the conditions found with your compressor outfit.
The modifications will depend upon the hours of operation and the working environment. Compressor
outfits in an extremely dirty and/or hostile environment
will require a greater frequency of all maintenance
checks. The maintenance label mounted on the air
tank also lists the required maintenance checks.
For additional maintenance instructions, recommended
oil and fuel on the gasoline engine, refer to "Gasoline
Engine Owners Manual".
3. Close the air discharge valve.
4. Remove air tool or accessory.
5. Open outlet valve or regulator to allow air to
slowly bleed from the tank. Close the outlet
valve or regulator when the tank pressure is
approximately 20 psig.
6. Drain water from tank.
NOTE
Drain and refill the compressor pump
crankcase after the first 100 hours of
operation. Add approximately 60 oz..
to pump.
Drain and refill the gasoline engine crankcase
after the first 20 hours of operation. See “Gasoline
Engine Owners Manual” for engine crankcase
capacity.
2. Drain water from the air tank and any
moisture separators or transformers.
3. Check for any unusual noise and/or vibration.
4. Manually check the safety valve to make sure
it is operating properly.

CLEANING THE AIR COMPRESSOR
OUTFIT
The external components of the compressor outfit
should be cleaned at least once a week. The air compressor crankcase and head are designed with fins
which allow for proper cooling. Clean or blow off fins
and any other parts of the outfit that collect dirt or
dust. A clean compressor runs cooler and provides
longer service.
MONTHLY
1. Check the alignment of the engine pulley to the
flywheel if necessary, align to within 1/16 inch.
2. Inspect for and correct any oil leaks.
3. Check drive belt tension adjust if necessary.
4. Inspect air lines and fittings for leaks; correct as
necessary.
EVERY 50 HOURS OF OPERATION
1. Clean the gasoline engine air cleaner.
EVERY 100 HOURS OF OPERATION
1. Drain and refill the gasoline engine crankcase
with clean oil.
2. Clean and set gap or replace spark plug.
3. Clean fuel sediment cup.
CHECKING AND CHANGING OIL
Overfilling with oil will cause premature
air compressor failure. Do not overfill.
1. Check oil level in compressor crankcase
before each use.
For two stage compressors the oil level should
be to the middle of the oil sight glass.
NOTE
The compressor pump oil must be
changed after the first 100 hours of
operation.
Changing Oil:
1. Remove the oil fill and drain plugs. Collect the oil
in a suitable container.
2. Replace the oil drain plug and refill the crankcase
with recommended oil. Refer to page 14 of this
manual for recommended compressor oil.
EVERY 500 HOURS OF OPERATION
1. Drain and refill compressor crankcase with clean
oil.
EVERY 2000 HOURS OF OPERATION, OR IF
A PROBLEM IS SUSPECTED
1. Check condition of compressor pump intake
and exhaust valves. Replace if damaged or
worn out.
NOTE
It is important to maintain the proper
oil level. A low oil level reduces
proper cylinder wall lubrication and
increases ring wear.
3. Replace the oil fill plug.
4. Start the engine and run the compressor outfit
for several minutes. Shut the compressor down
and check the oil level. If necessary add more
oil.
PAGE 15
Page 16
CHECKING AND CHANGING AIR
INTAKE FILTER
NOTE
Keep the air filter clean at all times. Do
not operate compressor outfit when
the filters are removed.
The condition of the air intake filter should be checked
once a week. A dirty air intake filter will not allow the
compressor to operate at full capacity and will increase
oil usage.
Open the drain valve. Continue operating outfit until
all moisture is removed from the tank. Close the drain
valve tightly.
NOTE
If the draincock is clogged, release
the air pressure in the tank. Remove
the drain valve and clean or replace.
Apply sealant to the threads before
reinstalling the drain valve.
When the air filter becomes dirty, oily, or covered with
paint overspray it must be replaced. To check and/or
replace the air intake filter, remove the screw securing
the filter assembly to the air compressor pump. Remove the filter. Inspect condition of filter; replace if
necessary.
NOTE
Felt and foam intake filters can be
washed in non-explosive solvent.
Allow to dry and reinstall. DO NOT OIL
INTAKE FILTERS.
DRAINING WATER FROM AIR TANK
Water will condense in the air tank.
If not drained, the water will corrode
and weaken the air tank. A weakened
tank may explode or rupture causing
personal injury. Drain the tank as
instructed below.
Water should be drained from the air tank daily. If
humidity is high the tank should be drained at regular
intervals during the day. Operate the compressor
outfit to allow 15 to 20 psi air pressure in the tank.
CHECKING AND ADJUSTING BELT
TENSION
Serious injury or damage may occur
if parts of the body or loose items get
caught in moving parts. Never operate
the compressor outfit with the belt
guard removed. The belt guard should
only be removed after the spark plug
wire has been disconnected.
The drive belt should be kept in proper tension as a
loose belt will slip and wear faster. An over tightened
belt will place an excessive load on the engine and
compressor pump bearings causing premature failure. The belt tension should be checked as follows:
1. Disconnect the spark plug wire and drain all air
pressure from the air tank.
2. Remove the belt guard.
3. Loosen all engine mounting hardware and slide
the engine either toward or away from the
compressor until correct belt tension is
achieved.
PAGE 16
Page 17
4. Hold the belt tension until the engine mounting hardware can be tightened.
5. Ensure that the belts are centered on the
engine pulley and compressor flywheel.
NOTE
Once the engine has been moved
from its factory set location the engine
pulley must align to within 1/16 inch
to the compressor flywheel.
Figure 8. Checking Belt Tension
On compressors equipped with standard V-belts,
each belt should deflect 1/4” at the midway point
between the engine pulley and flywheel when a
downward force of 4 pounds, or equivalent finger
pressure, is applied at the midway point. Refer to
Figure 8.
SERVICE INSTRUCTIONS
6. Torque engine mounting bolts to 20
foot pounds.
7. Reinstall the belt guard.
8. Connect the spark plug wire.
+3
Moving parts, unexpected engine start-up and compressed air can cause serious injury.
Always disconnect the spark plug wire and relieve pressure from the air tank before
performing any of these service procedures. Never operate the air compressor with the
belt guard removed.
REPLACING DRIVE BELT
The gasoline engine is mounted to the tank assembly saddle. By loosening engine mounting hardware,
the engine can be moved to allow for easy removal
of the belt. Replace the drive belt as follows:
1. Disconnect the spark plug wire and drain all air
pressure from the tank.
2. Remove the belt guard.
3. Loosen the engine mounting hardware and
slide the engine toward the compressor.
4. Remove the belt and replace with a new one.
On compressor outfits with matched Vbelts, both belts must be replaced at the same
time.
NOTE
The belts should be centered on
the flywheel and engine pulley. Once
the engine has been moved from its
factory set location, the engine
pulley must align to within 1/16
inch of the flywheel.
PAGE 17
Page 18
REPLACING DRIVE BELT (cont’d)
5. Slide the engine back into its original position
and adjust the belt tension, Figure 8.
For compressors equipped with standard V-belts,
the proper tension for each belt is approximately
1/4 inch belt deflection measured midway between
the engine pulley and flywheel when a 4 pound
downward force, or equivalent finger pressure, is
applied at that point.
6. Hold the belt tension until the engine mounting
hardware can be tightened.
7. Torque engine mounting bolts to 20
pounds.
8. Reinstall the belt guard.
9. Connect the spark plug wire.
+3 foot-
6. Reinstall the drive belt. Make sure the belt
is centered on the engine pulley and flywheel.
7. Slide the engine back into its original position
and adjust the belt tension, Figure 8.
For compressors equipped with poly-V-belts, the
proper tension is approximately 1/4 inch belt
deflection measured midway between the engine
pulley and flywheel when a 3 pound downward
force, or equivalent finger pressure, is applied at
that point.
For compressors equipped with standard V-belts
the proper tension for each belt is approximately
1/4 inch belt deflection measured midway between
the engine pulley and flywheel when a 4 pound
downward force, or equivalent finger pressure, is
applied at that point.
8. Hold the belt tension until the engine mounting hardware can be tightened.
ENGINE PULLEY AND FLYWHEEL
ALIGNMENT
The engine pulley and flywheel must be aligned to
prevent excessive wear of the drive belt and to keep
the belt from coming out of the pulley and flywheel
grooves. Align the belts as follows:
Serious injury or damage may occur if
parts of the body or loose items get
caught in moving parts. Never operate
the compressor outfit with belt guard
removed. Remove belt guard only after
the spark plug had been disconnected.
1. Disconnect the spark plug wire and drain
all pressure from the air tank.
2. Remove the belt guard.
3. Loosen all engine mounting hardware and
slide the engine toward the compressor. Remove the drive belt.
4. Loosen the engine pulley set screw and move
the pulley toward or away from the engine until
the pulley aligns with the flywheel within 1/116
inch.
5. Torque the engine pulley set screw to 75 +5
inch-pounds.
9. Torque the engine mounting bolts to 20
pounds.
10. Reinstall the belt guard.
11. Connect the spark plug wire.
CHECK VALVE INSPECTION AND CLEANING
Remove and inspect the check valve at least once a
year and more often if the compressor is heavily
used. Moisture and other contaminates in the hot
compressed air will cause an accumulation of
carbon-like residue on the working parts. If the valve
has heavy carbon build-up, it should be replaced.
Use the following procedure to inspect, clean, or
replace the check valve:
1. Disconnect the spark plug wire and release all air pressure from the air tank.
2. Loosen the top and bottom tube nuts
and remove the outlet tube.
3. Unscrew the check valve (counterclockwise) from the air tank using a socket
wrench.
4. Check that the valve and disc moves freely
inside the check valve and that the spring
holds the disc in the upper closed position.
The check valve may be cleaned with a
solvent.
5. Apply pipe sealant to the check valve threads.
+3 foot-
PAGE 18
Page 19
6. Reinstall the check valve. DO NOT OVER-
TIGHTEN.
SERVICING INTAKE AND EXHAUST VALVES
Many solvents are highly flammable
and a health hazard if inhaled. Always
observe the solvent manufacturers
safety instructions and warning.
The intake and exhaust valves as well as the valve
plates and cylinder head will, over a period of time
accumulate residue of carbon-like material on their
surfaces. The material will decrease the efficiency
of the compressor. These components should be
inspected, whenever a problem is suspected, and
cleaned or replaced with new parts. Use the following procedure to inspect the parts.
During service or repair activities
always disconnect the spark plug wire
before attempting repair maintenance
on compressor outfit. Make sure the
pressure is released from the air tank.
1. Disconnect the spark plug wire and drain
all air pressure from the air tank.
2. Service two stage compressor valves
as follows:
a. Remove the screws securing the
intercooler to the cylinder head and
remove the intercooler.
b. Disconnect the outlet line from the
aftercooler.
e. Clean carbon deposits in head cavities and
valves plates with lacquer thinner or
other suitable solvent.
f. Remove the intake and exhaust valve
assemblies from the valve plate. Clean and
inspect the valves, and valve retainers.
Replace any defective components as
necessary.
g. Reassemble the intake and exhaust
valves.
NOTE
Do not use gasket cement on any
gasket surface as this may clog the
compressor valve cavities and flow
areas.
h. Reinstall the valve plate. Use a new
valve plate gasket.
i. Install the cylinder head. Use a new
head gasket. Snug the mounting screws
tight then torque to 35 foot-pounds
using a criss cross pattern when torquing.
j. Install a new after cooler gasket. Secure
the aftercooler with the mounting screws
removed.
c. Remove the screws securing the
aftercooler to the cylinder head and
remove the aftercooler.
d. Remove the hardware securing the
cylinder head and remove the
