Component Installation
Chapter 2 - 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.
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:
From the air pressure switch there are two (2) wires, red and black, running to the outside
of the compressor housing. Connect the black wire to the vehicle frame or other suitable
ground. Mount a single throw toggle switch in a convenient location and connect the red
wire from the compressor to this switch. Connect the other switch terminal to a fuse holder
and then to a 12- volt power supply. A third wire is required from the air compressor switch
when connecting the speed control into the system.

The hydraulic system consists of the pump, oil reservoir, filters and hoses. Installed on the
compressor is a valve block assembly that controls the flow to the hydraulic motor. To this
block, a 1/2” high-pressure hose must be attached. This hose comes from the pressure
side of the hydraulic pump. A 3/4” minimum low-pressure return line is connected to the
oil cooler outlet and is routed to the oil reservoir. American Eagle recommends a sufficient
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 are added to
the hydraulic system. Pressure on the return line exceeding 200 PSI can and will cause
damage to the filter, cooler, and components of the compressor hydraulic system.
The airline is routed using a 3/4” (200 psi) air 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. American Eagle recommends the installation of a ten gallon air tank
(minimum) to maintain proper operation of the air compressor.

Pressure Setting Instructions:
1. Always set the kick out pressure setting first. Adjust the kick out screw setting to 145 psi
minimum/150 psi maximum.
2. After kick out pressure is set, adjust the kick on screw setting to 115 psi minimum/120 psi
maximum.
3. Cycle compressor to verify correct settings.
4. For questions about this procedure, please contact American Eagle Customer Service at
