2-1. GENERAL
This section deals with the installation of the PTO
and pump and the IMT hydraulic compressor. The
instructions are intended as a guide to assist you
with your particular installation. We can not cover
every make, model and year of truck manufactured
world-wide, so these instructions will provide only
general information. Use this section as a guide
only.
2-2. PTO AND PUMP INSTALLATION
The pump may either be installed directly on the
PTO or, as an optional method, it may be driven by a
driveline.
2-2-1. PTO INSTALLATION
Power take-off manufacturers provide specific
installation instructions for their products. Those
instructions should be followed when installing a
PTO. Some trucks may require modification of the
transmission cross-member to provide clearance and
the exhaust pipe may need modification. Check
with the PTO manufacturers representative for
specific instructions regarding your particular make,
model and year of vehicle. The following
instructions are a guide in this application.
1. If the vehicle is new, drain the transmission oil
into a clean container for reuse. If the vehicle is
used, drain and dispose of the transmission oil.
2. Temporarily install the PTO with the proper
gaskets and only two studs. Snug the PTO down
and check the backlash for maximum allowance of
1/32" to 1/16". If the backlash is excessive, remove
gaskets and check backlash again until it is
corrected.
3. Remove the PTO and apply Permatex® to the
gaskets. If the holes for the studs are tapped through
the transmission housing, apply Permatex to the
studs and tighten them down. Make certain that the
studs do not interfere with the transmission gears.
CAUTION
AVOID CONTACT OF PERMATEX WITH AUTOMATIC
TRANSMISSION FLUID.
4. Install the PTO and gaskets. Torque the nuts to
30 - 35 ft-lbs (4.14 - 4.84 kg-m) for a 6-bolt PTO
and 45 - 50 ft-lbs (6.22 - 6.91 kg-m) for 8-bolt
PTOs. Recheck the backlash.
5. Install the shifter cable to suit conditions.
Always allow for a slight overshift on lever or knob
to ensure the PTO is fully disengaged.
CAUTION
ITISIMPORTANTTHATROOMBEALLOWEDFOR FULL
ENGAGEMENT OF THE PTO. MODIFYTHE EXHAUST
OR OTHER OBSTRUCTIONS AS NEEDED.
CAUTION
AVOID SHARP BENDS IN THE SHIFTER CABLE. ALL
BENDS SHOULD HAVE AT LEAST A 6" RADIUS.
TIGHTERBENDS WILLCAUSE DIFFICULTOPERATION
OF THE SHIFTER KNOB.
6. Replace the transmission oil. If the PTO is
located below the transmission oil level, an
additional quantity of oil will be required.
7. Start the engine, engage the PTO and allow it to
run for 5-10 minutes. Check for leaks, unusual noise
and proper operation.
8. Retorque the mounting bolts.

DA440HU: 99900782: 2-2 WARNING

Oil coolers vary in their installation dependent on
available space and other considerations. Install the
oil cooler either in front of the carrier vehicle’s
radiator or, as an alternative, in a protective structure
which is cooled by an electric fan. Refer to Figure
B-4 for general location within the hydraulic system.

DA440HU: 99900782: 3-119950719 SECTION 3. OPERATION
3-1. INTRODUCTION
This section deals with the proper methods of
system operation and shutdown. These procedures
should be followed to prevent damage and ensure
efficient operation.
3-2. OPERATION
The compressor has an operating time limit of
approximately 3-hours depending upon ambient air
temperature (outside air temperature), weather
conditions and whether an oil cooler has been
installed.
CAUTION
THE HYDRAULIC OIL TEMPERATURE MUST NOT BE
ALLOWED TO EXCEED 190°F (88°C). IF THE OIL
TEMPERATURE REACHES THIS LIMIT, THE SYSTEM
MUST BE SHUT DOWN AND ALLOWED TO COOL.
Oil coolers will extend the 3-hour limit.
To start the compressor:
1. Ensure the PTO is disengaged, control valve is
open (pull the compressor switch out) and the
receiver drain cock is open.
2. Start the truck engine and allow it to idle until it
reaches the proper operating temperature (refer to
the Owners Manual).

DA440HU: 4-199900782: 19941223
Section 4. PREVENTIVE MAINTENANCE
FIGURE D-1. HYDRAULIC FLUID SPECIFICATIONS
4-1. INTRODUCTION
Proper maintenance on a regular schedule is
essential to keep your unit operating efficiently.
Proper maintenance procedures and required service
intervals are outlined in this section. Personnel
responsible for unit upkeep should become familiar
with frequency and type of maintenance required
and perform these tasks at recommended intervals.
4-2. LUBRICATION
The only lubrication required is on the carrier vehicle
and the compressor itself. Refer to the appropriate
Owners Manual for information on the truck and
compressor for the type and frequency of lubrication
required.
4-3. HYDRAULIC SYSTEM
4-3-1. HYDRAULIC FLUID SELECTION
Minimum viscosity specifications for hydraulic oil to
be used in the hydraulic system are given in Figure
D-1. Any major oil company can supply products
which meet these requirements.
Oils selected for use with this class of equipment, in
addition to meeting viscosity requirements, should
have the following additives:
1. Antifoam Inhibitors
2. Antioxidant Inhibitors
3. Rust Resistant Additives
4. Antiwear Additives
4-3-2. HYDRAULIC FLUID
SPECIFICATIONS
Figure D-1 states oil specifications for a full range of
operating temperatures encountered in the temperate
zones. Arctic conditions present special
requirements which are not in the scope of the table
and must be analyzed individually. Consult your oil
supplier for the proper hydraulic fluids for working
under these severe conditions. Electric reservoir
heaters are available to improve conditions at
extremely low temperatures.
4-3-3. HYDRAULIC FLUID
DETERIORATION
Contamination of the hydraulic fluid by solvents,
water, dust or other abrasives will cause deterioration
of the fluid. Sustained presence of the impurities will
result in premature breakdown of antifoam,
lubrication, anti-rust and viscosity properties.
Introduction of water to the system and operation at
high temperatures (above 180°F) will result in an
increase in the oil oxidation rate. Oxidation produces
varnish forming materials and sludge in the oil.
Operating the system on a sustained basis with
contaminated or broken down oil will increase wear
and can significantly shorten the efficient service life
of the unit.

DA440HU: 4-299900782: 19941223
Periodically, draw off a sample of the oil and check
the oil for breakdown. To check oil quality:
1. Place the oil in a clean glass.
2. Smell the oil to detect a burnt or rancid odor.
3. Visually examine the oil for a dark or cloudy
appearance.
4. Allow the sample to stand for several minutes.
Inspect the sample for water which will settle to the
bottom of the glass if present. Water can result from
a system leak or condensation due to temperature
extremes.
When any of these conditions is observed, the
system should be purged and filled with new oil. In
addition, the oil should be changed in the reservoir
and complete system:
1. After every 800 hours of operation or every six
months, whichever occurs first.
2. After pump or other major hydraulic component
failure, drain the hoses.
4-3-4. HYDRAULIC SYSTEM PURGING
Purging the hydraulic system requires a new oil
supply sufficient to completely fill the reservoir,
hoses, filters, valves, etc., and an extra allowance for
loss during this procedure. To reduce oil loss,
operate the engine at a low speed (idle).
When purging, new oil is supplied to the pump
suction line via the reservoir, and the old oil is
discharged through the reservoir return line.
Two operators will be required; one to operate the
compressor and the other to regulate pump flow
(engine speed).
Purging is accomplished as follows:
1. Drain the hydraulic reservoir and disconnect the
suction hose to the pump. Drain the hose and
reassemble. Change the suction filter cartridge
(Paragraph 4-3-5).
NOTE
THE METHOD OF WASTE DISPOSAL IS LEFT TO THE
DISCRETION OF SERVICE PERSONNEL.
2. Disconnect the reservoir return line at the
reservoir and direct the discharge into a sump or
waste container. Plug the return line port on the
reservoir and fill the reservoir with clean oil (refer to
Paragraph 4-3-1).
NOTE
BE THOROUGHLY FAMILIAR WITH THE FOLLOWING
STEPS AND PREPARED TO PERFORM THEM IN AN
UNINTERRUPTEDSEQUENCE. IFTHIS IS NOTDONE,
EXCESSIVE OIL WASTE WILL OCCUR.
CAUTION
DO NOT ALLOW THE RESERVOIR LEVEL TO DROP
BELOW 1/3 CAPACITY DURINGTHIS OPERATION.
3. Start the engine and engage the PTO. Slowly
release the clutch. Activate the control valve so that
the fluid passes through the motor. Allow fluid to
discharge for about 15 seconds. Kill the engine.
4. Reconnect the return line to the reservoir port
and change the return line filter. All components of
the system are now purged.
5. Check the reservoir oil level and add oil as
necessary.
4-3-5. FILTER ELEMENT
REPLACEMENT
To avoid residue accumulation in the reservoir and to
protect the hydraulic components (valves,
pumps,motors, etc.), the filters must be serviced on a
regular basis.
They must be changed after the initial 50-hours of
new unit operation and every 200-hours thereafter.To
change filter elements:
1. Shut the gate valve and remove the filter
element.
2. Install the new filter ensuring proper rubber seal
seating and tighten as much as possible using both
hands.
3. Open the gate valve and check for leaks.

SECTION 5. REPAIR
19941223
5-1. INTRODUCTION
This section deals with the disassembly and repair of
the components as well as troubleshooting
information.
5-2. HYDRAULIC SYSTEM
COMPONENTS
Disassembly and repair of components in the
hydraulic system requires special consideration for
proper functioning and service life of the unit.
These steps are to be followed whenever a hydraulic
component is removed from the system.
1. ALWAYS relieve internal hydraulic pressure
before proceeding with a repair, carefully loosen a
fitting and allow the pressure to bleed off.
2. NEVER allow foreign matter (dirt, water, metal
particles, etc.) to enter the system through the open
connections. Cap or plug any openings. If dirt does
get in, a filter change is required after 50 hours of
operation.
3. ALWAYS check for high pressure leaks after
completing a repair. A high pressure leak is
hazardous and must be repaired.
5-3. DRIVE BELT
To adjust the drive belt tension and alignment:
1. Loosen the four bolts securing the motor
mounting bracket to the base plate.
2. Turn the drawbolt in a clockwise direction to
tighten the belt until there is 1/4" - 1/2" play at the
center of the belt between the pulleys.
3. Adjust the alignment drawbolt until the motor
pulley is square with the compressor. Use a
straightedge across the compressor pulley (Figure E-
3) and check the gap between the motor pulley and
the straight edge. The gap (1-3/4") on the
compressor side of the motor pulley should be the
same as on the far side of the pulley.
