SECTION 2. INSTALLATION
FIGURE B-1. PTO INSTALLATION
2-1. GENERAL
This section pertains to the installation of the IMT
DA435HAR 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.
TIGHTER BENDS WILL CAUSE DIFFICULT OPERATION
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.
