INSTALL REMOTE VALVE CONTROL
CAUTION: WHEN DRILLING THE TRUCK FRAME BE CAREFUL OF
BRAKELINES, WIRING, ETC. INSIDE THE TRUCK FRAME.
Drill 17/32” holes in the truck frame and bolt the reservoir/valve assembly in place using 1/2 x 1 3/4” cap
screws, lock washers and hex nuts.
Temporarily assemble the valve control head to the pedestal using 5/16 x 2 1/4” machine screws and hex
nuts. Place this assembly on the floor of the cab. Make sure there is enough room to operate the valve con
-
trol and the gear shift lever and to adjust the seat. Check below the floor for obstructions and cable routing.
Relocate the valve control if necessary. Mark the floor using the pedestal as a template and drill 1/4” holes
for the mounting screws and a 3/4” hole for the control cable. Assemble the control cable to the valve
control head and assemble the valve control head and cover to the pedestal using 5/16 x 2 1/4” machine
screws, lock washers and hex nuts. Insert the control cable through the hole in the floor and mount the
pedestal to the floor using 5/16 x 3/4” self-tapping screws. Make sure the valve control lever is in its center
detent position. Keep the control cable away from hot exhaust pipes and rotating drive shafts. The control
cable should not have any sharp bends or kinks in it (these will make the control harder to operate).
Install the 3/4” hex jam nut onto the valve end of the control cable and turn past the threads. Insert the end
of the cable through the bonnet clamp. Install the bonnet onto the control cable and turn it past the threads
also. Install the 1/4” hex jam nut and terminal eye on the core rod of the cable. Lock the terminal eye to
the core rod using the hex jam nut. Place the terminal eye in the slot of the valve spool; insert the short pin
through the valve spool and terminal eye and secure it in place with the cotter pin.
Thread the bonnet onto the end of the cable so it firmly touches the end valve. (Do not over or under
tighten the bonnet as either would move the valve spool out of its neutral position.) Remove two cap
screws from opposite corners of the seal retainer plate. Slide the bonnet clamp onto the bonnet and secure
it to the valve using the 1/4 x 1 1/4” cap screws, lock washers and flat washers. Lock the bonnet to the
cable using the 3/4” hex jam nut. See Fig. 6.
INSTALL HOSES - 1900
Study Fig. 7 very carefully before connecting the hoses. Install a 3/4’’ 90° street elbow and a 3/4” hose
barb in the suction port on the bottom of the reservoir. Install a 1 1/16 ORB x 3/4” hose barb in the suction
port on the pump and install the suction hose. Secure the suction hose in place using hose clamps. Install
a 1 1/16 ORB x 7/8 ORB adapter in the pressure port of the pump and install a 90° swivel adapter in the
`IN’ port on the control valve. Install the 72” long 1/2” hose from the pump to the valve.
Install 90° swivel adapters in the work ports of the control valve and the ports on the base end of the cyl-
inders; install straight swivel adapters in the ports on the rod end of the cylinders. Connect 18” long 3/8”
hoses from the rod end ports of the cylinders to a swivel nut tee; connect a 60” long 3/8” hose from this tee
to the ‘A’ port on the control valve. Connect 18” long 3/8” hoses from the base end ports of the cylinders
to a swivel nut tee; connect a 60” long 3/8” hose from this tee to the ‘B’ port on the control valve. This
will raise the hoist when the control lever is pulled back and lower it when pushed forward. Secure the 18”
long hoses to the cylinder mount using the tie straps provided.
NOTE: The `A’ port is the `power-down’ port and has a pressure of only 500-1000 PSI at engine idle; the
`B’ port has full system pressure.
Study Fig. 8 very carefully before connecting the hoses. Install a 1 1/4’’ 90° street elbow and a 1 1/4”
hose barb in the suction port on the bottom of the reservoir. Install a 1 5/16 ORB x 1 1/4” hose barb in the
suction port on the pump and install the suction hose. Secure the suction hose in place using hose clamps.
Install a 1 5/16 ORB x 1/2 NPT adapter in the pressure port of the pump and install a 90° swivel adapter
in the `IN’ port on the control valve. Install the 72” long 1/2” hose from the pump to the valve.
Install 90° swivel adapters in the ‘B’ work port of the control valve and the ports on the base end of the
cylinders. Connect a 60” long 1/2” hose from the control valve to the swivel nut tee; connect 24” long 1/2”
hoseS from the tee to the ports on the base end of the cylinder. This will raise the hoist when the control
lever is pulled back and lower it when pushed forward. Secure the 24” long hoses to the cylinder mount
using the tie straps provided.
