NOTE: This compressor will mount on the right
(passenger) side of the engine. It may be necessary to
relocate or remove the air conditioning lines. If the oil is
low in the compressor, use Polyol Ester (P.O.E.) P.A.G. oil
and fill to specified amount.
I. AssemblingtheCompressor
1. Attach the clutch to the compressor using the four bolts that
come in the box with the clutch (Figure 2). Tighten the bolts
securely. NOTE: Make sure that the wire is at the bottom right
hand side of the compressor.
2. Placethe pulley(E) overthe clutch and align thekeyway. Attach
the pulley (E) using the provided hardware. Tighten securely to
the shaft (Figure 4).
3. Attach the small clamp that came with the clutch using bolt (FF)
andflat washer (GG). Route the wirethroughtheclamp (Figure
3).
4. Attach the plate (L) to the left side of the compressor (engine
side) using bolts (II), lock washers (JJ), and flat washers (GG).
Be sure to insert the carriage bolt (HH) before bolting the plate
down (Figure 5). NOTE: The long tab at the bottom of the
bracket faces the rear of the compressor (Figure 5).
5. Removethesmallboltontheopensideofthecompressorabove
the line clamp previously installed and check the oil level in the
compressorwith the supplied dipstick(AH). The oil levelshould
be from 1”to 11/4" on the dipstick. The compressor should have
a total of 8 fl. oz. (237 ml). Use Polyol Ester (P.O.E.) P.A.G. oil
only. Attach the plug and tighten.

1. Remove the belt, belt tensioner, positive battery cable, back
and side alternator bolts, computer and bracket, and radiator
overflow.
2. It will be necessary to slightly bend the inner fender to obtain
adequate clearance for the compressor. Use a pry bar or a 2 x
4 and pry using the frame (Figure 6).
3. Unbolt and move the evacuation line from the front of the
manifold to the rear of the manifold (Figure 7).
4. Removeandreplace the idler pulley with thepulley (F)supplied.
5. Attach bracket (P) and idler pulley back onto the vehicle using
the existing bolts removed (Figure 8). Tighten securely.
6. Install the upper bracket (N) using the existing bolt previously
removed (Figure 9). Leave loose at this time.
7. Installthebackbracket(O) using the 8mm bolt (LL), lockwasher
(NN), and flat washer (MM) provided. NOTE: The flange faces
to the rear of the vehicle. Leave loose at this time.

alternator, idler pulley, etc.).
6. Installthenewserpentinebelt(withair(B), NAPApart#25060945
or without air (C), NAPA part #25060849). Route the belt per
Figure 11. NOTE: Figure 11 is without air conditioning.
7. Be sure that the compressor and belt is fully aligned before
securing the mounting hardware. If not aligned, unattach the
beltandadjust the compressor as needed. Tighten all mounting
and bracket hardware only when all is fully aligned.

V. Installing theRadiatorOverflow
Reservoir
1. Remove the two bolts on the ABS/brake bracket on the driver
side fender (Figure 14) and attach the bracket (M) to the ABS
brake bracket using existing bolts removed.
2. Loosely attach the reservoir (G) to the bracket using bolts (PP),
flat washer (RR), and nuts (TT).
3. Mark the fender at the bottom using the bottom hole on the
reservoir, center punch and drill a 1/4" hole, being careful no to
drill the tire. Reattach the reservoir in all three mounting
locations.
4. Pull the overflow hose out of the clamps under the radiator.
Reroute to the bottom of the reservoir. Cut and attach the hose
usingclamp (UU) provided. Filltheradiatorhalf way with radiator
fluid (Figure 14).
VI. Checking the Belt
1. Attach the positive battery cable.
2. Check all hardware to be sure that it is secure.
3. Start the engine and observe the belt and pulley for alignment.
NOTE: DO NOT ENGAGE CLUTCHYET. Adjust if necessary.
VII. Installing the Filter
1. Using the provided thread sealant, assemble the bushing (Z)
and relief valve (W) to the brass street tee (EE). Install a 1/2"
NPTM x 1/2" tube straight fitting (Y) to the tee (Figure 1).
2. With the arrow pointing in the direction of the flow, assemble
the coelescing filter (H) to the brass tee assembly using the
supplied sealant (Figure 1). Tighten securely.
3. Securelyattach a 1/2" NPTM x 1/2" tube straightnipple (AI) to the
port on the coelescing filter (Figure 1).
4. Looselyattach the filter bracket (Q)tothefilterusing the provided
screws (SS).
5. Find a remote location on the frame or in the rear with enough
clearance to install the filter assembly and use filter bracket as
atemplate to mark mounting locations. Removefilterassembly
and drill the mounting hole locations with a 1/4" bit.
6. Remove the filter from the bracket and install the bracket using
the self tapping bolts (QQ). Tighten securely (Figure 15).
7. Reattach the filter to the bracket and tighten screws securely
(Figure 15).

VIII. InstallingtheHoseAssembly
1. Install the brass cross bracket (AA). Using the bracket (R) as a
template, mark and drill the two 1/4" mounting holes and attach
using two bolts (PP) and two nuts (TT).
2. Attach the bushing (CC) and pressure switch (X) to one leg of
the brass cross (AA) and plug (BB) to the other leg directly
across from the pressure switch (Figures 1 and 16).
3. Attach the brass cross to the bracket using a 1/2" NPTM x 1/2"
tube straight fitting (Y) on each side (Figures 1 and 16).
4. Install a 1/2" NPTM x 1/2"tube straight fitting(Y) to oneendof the
check valve (V) (Figure 1). Tighten securely. The check valve
will be installed to the filter assembly. NOTE: The arrow points
inthedirectionofthe flow and the fitting goes onto thedischarge
end of the check valve.
5. Use the provided hose cutter (AG) to cut a length of ½" hose
long enough to run from the cross assembly to the air fitting on
the filter assembly. Do not attach at this time.
6. Being sure that the arrow on the check valve points in the
direction of the flow, attach one end of the hose into the push-
to-connect fitting on the check valve. Route the other end to
the fitting on the cross assembly (Figure 1).
7. The open leg on the cross routes into a 1/2" hose going to the
existing air tank (Figure 1).

8. Using the thread sealant provided, assemble two of the brass couplings (DD) to both ends of the steel leader hose
(J). Tighten securely (Figures 1 and 17).
9. Remove the caps to the discharge and supply ports on the top of the compressor.
10. Slide the O-rings (U) around the two sleeve inserts (T). Set the inserts into the port holes on top of the compressor.
11. Set the compressor fittings (S) over the inserts and loosely attach using the existing bolts removed.
12. Attach a coupling (DD) and filter (I) to the supply side (the side closest to the engine) using the provided sealant.
Position the filter and tighten the compressor fitting bolt securely.
13. Firmly attach the steel leader hose to the remaining compressor fitting using the provided sealant (Figures 1 and
11).
14. Attach a 1/2" NPTM x 1/2" tube (Y) fitting to the opposite end of the leader hose.
15. Tighten the bolts on both compressor fittings securely.
16. Attach a length of hose (AF) from one end of the leader hose to the fitting on the relief valve assembly on the filter
(Figure 1).
IX. Checking the Oil
Use a dipstick (AH) to check the oil depth. The depth must be between 1" and 11/4" (Figure 13). If this is not done, the
warrantywill be void.

ImportantWarranty Information
1. If the compressor or engine is run without having oil in the compressor, then the warranty
is void.
2. If the belt is misinstalled or the belt does not have the proper tension, then the warranty is
void.
3. Failure to use included installation components properly voids the warranty.
4. Failure to check proper oil level and conditions will void the warranty.
5. This compressor must only be used in an air compressor application only, not an air
conditioning application. No freon is required.
6. It is necessary to periodically check the filter for trapped oil. This needs to be performed
three or four times a year. Failure to do so will result in reduced component life.
X. Wiring the Electrical System
1. The hot lead to the compressor is the black wire on the clutch. Cut off the fitting on the end of the black wire and
using butt connector (ZZ), splice a length of the red wire (WW) to the black wire. Run red wire to spade terminal on
the pressure switch. Attach a blue spade connector (AB) to the red wire and attach to one of the terminals on the
pressure switch.
2. Splice the 20 amp fuse in the fuse box using the adapters provided into a hot keyed power source and run it to the
other terminal on the pressure switch.
3. After all hardware has been secured and oil level is within range, the system is now ready to operate. See Figure
18 for a finished installation.
4. We recommend purchasing a spare belt to carry in the vehicle in case of a belt failure.
5. Check all fittings and air line connections for leaks with a solution of 1/5dish soap to 4/5water in a spray bottle.
