PART 2-6 - AIR SUPPLY SYSTEM 2-73
INSTALLATION
Fuel Pump and Air Compressor—
F-, H-, T- and N-Series Trucks
1. Clean the gasket material from
the compressor, gear case, and accessory
drive rear support plate.
2. Position the air compressor with
a new gasket to the front side of the
gear case so that the timing marks
on the air compressor drive gear are
aligned with the marks on the camshaft
gear (Fig. 12). Be sure that the
gears mesh properly.
3. Position the accessory drive
rear support plate with a new gasket
to the rear side of the gear case, then
secure the support plate and air compressor
to the gear case with the
lockwashers and retaining bolts.
4. On F-, T- and N-Series trucks,
clean the gasket material from the
water crossover pipe and the rear of
the cylinder heads. Position the crossover
pipe to the cylinder heads with
new gaskets and install the retaining
bolts.
5. Connect the two water lines
(compressor - to - cylinder block and
compressor-to-water crossover connection).
6. Connect the main air outlet
line to the compressor.
7. Connect to the governor all air
lines that were disconnected during
removal.
8. On F- and T-Series trucks, connect
the compressor air intake hose
and secure with two clamps.
9. Secure any water or air line-tosheet
metal clamps that were disconnected
during removal.
10. On F-, T- and N-Series trucks,
install the floor pan cover at the gear
shift lever.
11. Clean the gasket material from
the pump mounting surfaces, position
a new gasket, install the fuel pump to
the front side of the compressor, and
connect the throttle linkage and lines
as described in Group 10.
12. On F- and T-Series trucks, fill
the cooling system, charge the reservoirs
and check for leaks.
On H- and N-Series trucks, first install
the air intake system components
as outlined in the following procedure.
Air Intake Lines-H- and N-
Series Trucks Only
1. Install the right air cross-over
manifold to the engine intake manifold,
connect the compressor air intake
hose to the cross-over manifold
and to the compressor, and
position the connection hose on the
right and left cross-over manifolds
(Fig. 11).
2. Install the air cross-over manifold
retaining bolts, and tighten the
two clamps on the compressor air intake
hose.
3. Tighten the clamps on the connection
hose.
4. Connect the air intake duct to
the air cross-over manifold and
tighten the clamp.
5. Fill the cooling system, charge
the reservoirs, and check for leaks.
GOVERNOR
REMOVAL
The governor is mounted to the
compressor with two retaining bolts.
Mating ports in the governor and
compressor bodies connect governor
pressure to the unloading pistons in
the compressor. Reservoir pressure
is connected to the governor through
a hose or tube.
1. Exhaust the air brake system.
2. On vertically-mounted units,
disconnect the governor hose (end
opposite governor) from the fitting
in the reservoir pressure line. On
side-mounted units, disconnect the
pressure line at the governor.
3. Remove the two mounting
bolts, then remove the governor.
INSTALLATION
1. On vertically-mounted units,
transfer the hose to the replacement
governor.
2. Install the governor and gasket
and the two retaining bolts to the
compressor. Apply sealer.
3. On vertically-mounted units,
connect the hose to the fitting on the
reservoir pressure line. On sidemounted
units, connect the pressure
line to the governor.
4. Test the governor as outlined
in Part 2-1.

dash panel (Fig. 13), and taps into a
reservoir pressure line on the engine
side of the panel.
REMOVAL
1. Turn the ignition switch to the
"off" position and exhaust the air
from the brake system.
2. Disconnect the wire at the
buzzer switch.
3. Disconnect the air line to the
dash gauge and the line to the windshield
wiper control. On some full
air systems, also disconnect the lines
to the tractor protection valve, to the
manual emergency valve, and to the
hand control valve (Fig. 13).
4. Unscrew the pressure indicator
fitting at the engine side of the dash
panel, and remove the assembly from
the passenger side.
INSTALLATION
1. Mount the replacement unit to
the passenger side of the dash panel
and secure it to the panel by screwing
on the pressure indicator fitting
at the engine side.
2. Connect the wire to the buzzer
switch, and connect the dash gauge
and windshield wiper control lines.
On some full air systems, connect the
other lines as shown in Fig. 13.
MAJOR REPAIR OPERATIONS
Major repair operations are not
applicable to this section. If the compressor,
reservoirs, governor, low
pressure indicator, and/or dash
gauge is defective, the component
must be replaced.
