Chapter 2 - Installation
Component Installation
This section pertains to the installation of the air compressor, PTO, pump and other related
items. The instructions are intended as a guide to assist you with particular installation.
These instructions will provide only general information.
Compressor Torque Procedure
Pulsation Chamber Assembly:
Torque Value: 31 ft-lbs
Procedure: See Head Assembly Procedure
Head Assembly:
Torque Value: 34 ft-lbs
Procedure: Assemble head on the cylinder with head bolts
started only, not tight. Working in the pattern shown, torque
three times, increasing the torque each time as follows:
First Torque: 10 ft-lbs
Second Torque: 20 ft-lbs
Third Torque: 34 ft-lbs
After five hours of use re-torque bolts to 34 ft-lbs.
Cylinder Assembly:
Torque Value: 20 ft-lbs
Procedure: After assembling cylinder over pistons and setting into place, tighten (6) cap
screws finger tight. In a criss-cross pattern, tighten bolts evenly so all bolts are hand snug.
Again in a criss-cross pattern torque each bolt to 20 ft-lbs, checking each bolt twice. After
five hours of use, re-torque bolts to 20 ft-lbs.
Connecting Rod Control:
Torque Value: 18 ft-lbs
Procedure: Assemble rod onto the crankshaft taking care to align the machined surfaces
together and tighten cap screws finger tight. Tighten bolts until hand tight and torque to 18
ft-lbs. Check twice the torque reading before final assembly of the cylinders.

Pump Assembly:
The pump assembly may either be installed directly on the PTO or as an optional
method, may be driven by a driveline from the PTO. Pump manufacturers provide specific
installation information for their products and should be consulted if questions arise.
Note: A dual or tandem hydraulic pump is recommended when additional hydraulically
operated equipment are added to the hydraulic system.
PTO Assembly:
Check with the PTO manufacturer’s representative for specific instructions regarding your
particular make, model, and year of vehicle. As some trucks may require modification of
the transmission cross member and the exhaust system, the manufacturer’s instructions
should be followed to ensure proper installation of the PTO.
Compressor Assembly:
Prepare the mounting location of the compressor by locating and drilling four (4) holes,
1/2” diameter as per the mounting pattern of the air compressor base. Using four (4) 3/8” x
1.25 GR-5 cap screws, 3/8” flat washer, and 3/8” nyloc nut, secure the compressor in place.
The compressor is air cooled, and must have a clean supply of cooling air to the fan with
minimum restrictions. Adequate space must be provided for proper circulation of air.
Electric Speed Control:
An optional electric or electronic speed control must be used to maintain proper
operating speed of the air compressor. The engine speed control will automatically
increase from idle to preset speed when engaged and decrease when disengaged.

Electrical Connections:
Supplied with the compressor is a wire harness pigtail which has 4 leads coming off of it.
Connect the black wire to the vehicle frame or other suitable ground. Connect the red
lead to a fused power source. Mount a single throw toggle switch in a convenient location
and connect the green wire from the compressor to this switch. Connect the other switch
terminal to a fuse holder and then to a 12V power supply. The yellow wire is required from
the compressor when connecting the speed control into the system.

The hydraulic system consists of the oil reservoir, pump, manifold, motor, filters, and
hoses. A ½” 3000psi pressure line should be connected to the pressure line fitting on the
bulkhead. This line is plumbed though an internal manifold block, and then to the motor.
After the motor there is an internal cooler which the oil passes through before going to
the return line bulkhead fitting. A ¾” minimum low-pressure return line is to connect to
the return bulkhead fitting and filter before being returned to the oil reservoir. American
Eagle recommends a sufficiently-sized reservoir be provided that includes the proper
suction and return filters. The cooler on the compressor is designed and sized to cool the
air compressor efficiently. An auxiliary oil cooler is required when additional hydraulically
operated equipment is added to the hydraulic system. Pressure on the return line
exceeding 200PSI can and will cause damage to the filter, cooler, and components of the
compressor’s hydraulic system.
The airline is routed using a ¾” 200 psi air/steam hose. This delivery line should be free from
all obstructions. Note: There should be no check valve installed between the compressor
and the air tank (One is already included in the compressor package). American Eagle
recommends the installation of a ten-gallon air tank (minimum) to maintain proper
operation of the air compressor.
