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.

Compressor Torque 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 ve 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

nger 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 ve 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 nger tight. Tighten bolts until hand tight and torque to 18 ft-lbs. Check

twice the torque reading before nal assembly of the cylinders.

Component Installation, continued

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 specic

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 specic instructions regarding your particular

make, model, and year of vehicle. As some trucks may require modication 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” at 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 o󰀨 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.

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.

PTO Assembly:

Check with the PTO manufactures 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

insure proper installation of the PTO.

Compressor Assembly:

Prepare the mounting location of the compressor

by locating and drilling four (4) holes, 7/16”

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 washers, and 3/8” nyloc nuts,

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.

FAN

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.

The electric cable pull speed control (American

Eagle P/N 25740) is used on most gasoline engines.

The electronic speed controls are used only on Ford

7.3 and 6.0L diesel engines. Proper installation

instructions are provided with each system.

Hydraulic 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 hydraulic pumps pressure side. 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 which 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 hydraulic system consists of the oil reservoir, pump, manifold, motor, lters, and hoses. A

½” 3000psi pressure line should be connected to the pressure line tting 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 tting. A

¾” minimum low-pressure return line is to connect to the return bulkhead tting and lter before

being returned to the oil reservoir. Stellar Industries recommends a su󰀩ciently-sized reservoir

be provided that includes the proper suction and return lters. The cooler on the compressor is

designed and sized to cool the air compressor e󰀩ciently. 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 lter, 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). Stellar Industries recommends the

installation of a ten-gallon air tank (minimum) to maintain proper operation of the air compressor.
