FIGURE B-1. PTO INSTALLATION
2-1. GENERAL
This section pertains to the installation of the IMT
DA425HA compressor, PTO and pump. The
instructions are intended as a guide to assist you with
your particular installation. These instructions will
provide only general information.
2-2. PTO AND PUMP INSTALLATION
The pump may either be installed directly on the
PTO (see Figure B-1) or, as an optional method, it
may be driven by a driveline (see Figure B-2).
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
properly.
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
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
IT IS IMPORTANT THAT ADEQUATE SPACE BE
ALLOWED FOR FULL ENGAGEMENT OF THE PTO.
MODIFY THE EXHAUST OR OTHER OBSTRUCTIONS
AS NEEDED.
CAUTION
AVOID SHARP BENDS IN THE SHIFTER CABLE. ALL
BENDS SHOULD HAVE AT LEAST A 6" RADIUS.
TIGHTERBENDS WILLCAUSEDIFFICULTOPERATION
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.

WARNING
THE INSTALLER OF THE DRIVELINE MUST INSPECT
THE FINAL POSITION OF THE DRIVELINE TO
DETERMINE WHETHER ITS LOCATION PROVIDES
SUFFICIENT PROTECTION TO AN OPERATOR, OR
OTHER PERSONNEL, FROM HAZARDSASSOCIATED
WITH A ROTATING DRIVELINE. IF PROTECTION IS
INSUFFICIENT, THE INSTALLATION OF A GUARD IS
REQUIRED. IF YOU ARE UNSURE OF METHODS TO
GUARD A ROTATING DRIVELINE, CALL IOWA MOLD
TOOLING CO., INC. FOR INSTRUCTIONS. FAILURE
TO DO SO MAY RESULT IN SERIOUS INJURY OR
DEATH.
19950922
2-2-2. DRIVELINE AND PUMP
INSTALLATION
The pump may be driven as shown in Figure B-2 as
an optional method to the one shown in Figure B-1.
The following steps are a guide in this application.
1. Install the PTO (refer to Paragraph 2-2-1).
2. Loosely bolt the pump mounting bracket (A) to
the adjustable bracket (B) in Figure B-2.
3. Bolt the adjustable bracket to the frame at a
point that will not exceed 48" (122cm) from the PTO
and will not cause a joint angle greater than 3°.
4. Check the pump rotation and install pump, pump
end yoke and PTO end yoke.
5. Size, cut and weld the driveline to the necessary
length. Ensure driveline balance. Allow 1"
(2.54cm) extra for PTO end yoke.
6. Install driveline, lock set screws and lubricate U-
joints.
7. Ensure all mounting bolts are tight.
FIGURE B-2. DRIVELINE & PUMP INSTALLATION
2-3. COMPRESSOR INSTALLATION
1. Prepare the mounting location of the compressor
by locating and drilling four (4) holes, 7/16"
diameter, as shown in Figure B- 3.
2. Position the rubber bumpers on these holes and
lift the compressor into place.
3. Using the four (4) 3/8-16x2-1/2" cap screws and
3/8" wraught washers, secure the compressor in
place by inserting the cap screws from below the
mounting surface as shown in Figure D-1.
4. Electrical Connections:
A. Connect the black wire to the vehicle frame
or other suitable ground.
B. Mount the single throw toggle switch in a
convenient location. Connect the red wire from
the compressor switch. Connect the other
terminal of the switch to the fuse holder and then
to a 12-volt power supply as shown in Figure D-
1.
C. The blue wire is to be connected to the speed
control through a relay.
CAUTION
DAMAGE MAY OCCUR IF THE COMPRESSOR IS NOT
CONNECTED TOA SPEED CONTROL.

DA425HA: 99900682: 3-119950922 SECTION 3. OPERATION
3-1. GENERAL
Each compressor is bench tested under load at the
factory to ensure proper break-in and operation.
While it is not necessary to follow any break-in
procedure, the following checks should be made
before putting the unit into service, as well as,
periodically during use.
1. Before start-up:
A. Check the oil level in the compressor
crankcase with the dipstick on the unit. If oil is
needed, use only IMT’s synthetic compressor oil.
B. Check the air intake filters on each
head to make certain that they are clean and
unobstructed. Dirty filters are a possible cause of
reduced air output.
2. With the compressor engaged:
Adjust engine speed to ensure that compressor
speed does not exceed 1400 RPM (max) under
load.
3-2. OPERATION
To use the compressor, start the vehicle engine and
engage the compressor by operating the compressor
switch.The system will now function automatically.
It will engage the compressor clutch when the air
pressure is below 120 psi, and disengage when the
air pressure reaches 150 psi.
NOTE
ON UNITS WITH MANUAL ENGINE SPEED CONTROL,
THE ENGINE RPM WILL INCREASE WHEN THE
COMPRESSOR CLUTCH DISENGAGES.
CAUTION
OPERATING THIS UNIT IN EXCESS OF 1400 RPM,
WILLVOIDTHEWARRANTY,ANDWILLSHORTENTHE
NORMAL SERVICE LIFE OF THE COMPRESSOR.
