2-1. GENERAL
This section pertains to the installation of the IMT
DA435HA compressor, PTO and pump. The
instructions are intended as a guide to assist ou
with our particular installation. These instructions
will provide onl general information.
2-2. PTO AND PUMP INSTALLATION
The pump ma either be installed directl on the
PTO (see Figure B-1) or, as an optional method, it
ma be driven b 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. Check with the PTO manufacturers
representative for specific instructions regarding
our particular make, model and ear 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
properl .
19980930SECTION 2. INSTALLATION
2. Temporaril install the PTO with the proper
gaskets and onl two studs. Snug the PTO down
and check the backlash for maximum allowance of
.006" to .012". If the backlash is excessive, remove
gaskets and check backlash again until it is
corrected.
3. Remove the PTO and appl Permatex® to the
gaskets. If the holes for the studs are tapped through
the transmission housing, appl 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.
Alwa s allow for a slight overshift on lever or knob
to ensure the PTO is full 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.

OF THE SHIFTER KNOB.
6. Replace the transmission oil. If the PTO is
located below the transmission oil level, an
additional quantit of oil will be required.
7. Start the engine, engage the PTO and check for
proper PTO rotation. Allow it to run for 5 - 10
minutes. Check for leaks, unusual noise and proper
operation.
8. Retorque the mounting bolts.
FIGURE B-1. PTO INSTALLATION

DA435HA: 99901219: 2-2 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 HAZARDS ASSOCIATED
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.
19980930
2-2-2. DRIVELINE AND PUMP
INSTALLATION
The pump ma 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.
NOTE
BEFORE INSTALLING DRIVELINE, REFER TO
PARAGRAPH 2-4 FOR PROPER DRIVELINE
INSTALLATION TECHNIQUES.
1. Install the PTO (refer to Paragraph 2-2-1).
2. Loosel 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 oke and PTO end oke.
5. Size, cut and weld the driveline to the necessar
length. Ensure driveline balance and run out meet
specification. Allow 1" (2.54cm) extra for PTO end
oke.
6. Install driveline in phase with proper operating
angle calculations, lock set screws and grease U-
joints and mating spline.
7. Ensure all mounting bolts are tight.
2-3. COMPRESSOR INSTALLATION
See Installation Kit Drawing in the Parts Section for
specific installation and parts information.

2-4. DRIVELINE INSTALLATION
TECHNIQUES
2-4-1. U-JOINT OPERATING ANGLES
Ever U-joint that operates at an angle creates
vibration.
U-joint operating angles are probabl the most
common cause for driveline vibration in vehicles
that have been reworked or that have had auxiliar
equipment installed.
When reworking a chassis or installing a new
driveshaft in a vehicle, make sure that ou follow
the basic rules that appl to u-joint operating angles,
as follows:
1. U-joint operating angles at each end of a shaft should
always be at least 1°.
2. U-joint operating angles on each end of a driveshaft
should always be equal within 1° of each other.
3. U-joint operating angles should not be larger than 3°. If
more than 3°, make sure they do not exceed the
maximum recommended angles for the RPM at which
they will be operating.
A u-joint operating angle is the angle that occurs at each
end of a driveshaft when the output shaft of the
transmission and the input shaft of the pump are not in
line. See figure.
The connecting driveshaft operates with an angle at
each u-joint. It is that angle that creates a vibration.
REDUCING AND CANCELING VIBRATION
A ke point to remember about u-joint operating
angles: To reduce the amount of vibration, the
angles on each end of a driveshaft should alwa s be
SMALL.
To cancel an angle vibration, the u-joint operating
angles need to be EQUAL within 1° at each end of a
shaft. See figure.
2-4-2. SINGLE PLANE AND COMPOUND
U-JOINT OPERATING ANGLES
There are two t pes of u-joint operating angles,
single plane and compound.
SINGLE PLANE
Single plane angles occur when the transmission and
pump components are in line when viewed from
either the top or side, but not both.
Determine the u-joint operating angle in an
application where the components are in line when
viewed from the top, but not in line when viewed
from the side, is as simple as measuring the slope of
the components in the side view, and adding or
subtracting those slopes to determine the angle. See
figure.
These angles should be SMALL and equal within 1°.
Determine the u-joint operating angles on a shaft
that is straight when viewed from the side and offset
when viewed from the top requires the use of a
special chart (See accompan ing chart). In this t pe
of application, the centerlines of the connected
components must be parallel when viewed from the
top, as shown. These angles should also be SMALL
and equal within 1°. See figure.
Look at the angle chart and note that the smaller the
offset, the smaller the resultant angle.
To reduce the possibilit of vibration, keep an
offset between connected points to a minimum.

DA435HA: 99901219: 2-419980930
There are two things which can be done to make
certain single plane angles are SMALL and
EQUAL:
Make sure that the transmission and pump are mounted
so that their centerlines are parallel when viewed from
both the side and the top.
Make sure the offset between them is mall in both views.
COMPOUND ANGLES
Compound u-joint operating angles occur when the
transmission and pump are not in line when viewed
from both, the top and side. Their centerlines,
however, are parallel in both views. See figure.
TRUE U-JOINT OPERATING ANGLE
The true u-joint operating angle, which must be
calculated for each end of the shaft with compound
angles, is a combination of the u-joint operating
angle in the top view, as determined from the chart,
and the measured u-joint operating angle in the side
view.
To determine the true u-joint operating angle for one
end of a shaft, (compound angle C° in the formula
shown in figure below) insert the u-joint operating
angle measurement obtained in the side view and the
u-joint operating angle obtained from the chart into
the formula.
Do the same for the other end of the shaft. Compare
the resultant calculated u-joint operating angle for
each end. The should be EQUAL within 1°. If the
are not, the driveshaft will vibrate.
2-4-3. ELIMINATING COMPOUND
ANGLE INDUCED VIBRATIONS
Compound u-joint operating angles are one of the
most common causes for driveline vibration. To
avoid thease problems, remember these important
considerations:
When setting up an application that requires compound u-
joint operating angles, always keep the centerlines of the
transmission and pump parallel in both views.
Always keep the offset between their horizontal and
vertical centerlines small.
NOTE
CENTERLINES OF TRANSMISSION AND AXLE MUST
BE PARALLEL IN BOTH TOPAND SIDE VIEWS TO USE
THIS METHOD OF DETERMINING TRUE U-JOINT
OPERATING ANGLE. CONTACT IMT TECHNICAL
SUPPORT IF YOU HAVE AN APPLICATION WHICH
CANNOT BE INSTALLED WITH THEIR CENTERLINES
PARALLEL.
