Topdeck Compressor Installation
The topdeck compressor is mounted on an oil reservoir which is bolted to the deck of the carrier
vehicle. Due to variations, use these instructions only as a guide.
1
Locate compressor position on the deck. Layout mounting hole pattern per figure. Drill six
1/2" holes for mounting. Locate the positions of reservoir ports per figure.

Using 3/8" bolts, flat washers, lock washers and nuts, secure the compressor and tank to the
deck of the truck.
3
Locate a position on the deck for a hole for the hose which runs from the pump to the control
valve. Position the hole to provide the least interference with truck frame members, exhaust
and driveshaft, and as near the compressor oil reservoir as possible. Drill a 1-3/4" hole at this
location. Place a 1-3/4" diameter grommet into the hole to help prevent hose wear.
4
Route the hose through the hole and connect it to the pump and control valve using the
fittings provided.
5
Drill a 2-1/4" hole in the bed of the truck for the hose from the cooler to the inlet side of the
return filter. Install 2-3/4" diameter grommet into hole. Position the hole to provide the least
interference with truck frame members, exhaust and driveshaft; and as near the compressor
reservoir as possible. Install hose from cooler to return filter.
6
Drill two 5/8" diameter holes through the deck for the hoses from the air driven throttle
control. Install the speed control on the engine. Route the hoses through these holes and
connect them as shown in the Parts Section.
7
Install the barbed nipples, hose and hose clamps from the suction port of the reservoir to the
suction filter.
8
Drill a 1" hole for the receiver drain as near the drain as possible and route a 1/2" diameter
hose through the hole. Connect one end to the receiver drain. This will prevent drainage of
the receiver onto the deck of the truck.
