2-3. TOP-DECK COMPRESSOR
INSTALLATION
Due to the large variety of carrier vehicles, the
instructions in this paragraph should be used as a
guide only. Refer to Figure E-2 for reference.
1. Position the compressor across the frame of the
truck in the desired location. The location selected
should provide adequate ventilation while at the
same time affording access to the compressor.
2. Lift the compressor base into position. Check
for belt clearance and approximate drive shaft
length.
3. Using the base as a template, drill four 17/32"
diameter holes. The 3/4-ton/RH will be drilled
through the top of frame rails. The 1-ton/LH will be
drilled through the sides of the frame rails.
4. On the 3/4-ton/LH, insert spacers between base
and frame rails. No spacers are used with the 1-ton/
RH. Bolt the compressor base to the frame of the
truck using the 1/2" hardware.
5. Using the appropriate driveshaft with knuckles
in place, measure the exact length required, cut off
excess shaft and weld in place (1/4" weld all
around).
6. Install the driveshaft to the PTO and the
compressor, tighten the lock bolts and tie-wire in
place.
7. Tighten all bolts per Torque Data Chart.
8. Connect the 3/4" air hose from the compressor
to the air tank.
9. Install the engine speed control and connect the
hoses from compressor to speed control.
