HYDRAULIC PUMP INSTALLATION

A mounting bracket for the hydraulic pump is shipped with the spreader. It may be necessary to
modify this bracket to fit your truck since many variable factors such as PTO make and model, muffler
position, transmission make and model, etc., all affect the mounting position. DO NOT WELD THE
BRACKET TO THE TRUCK FRAME. To do so may void the truck manufacturer's warranty.
Position the mounting bracket so that the pump drive shaft will be as straight as possible. In no case
should the angle of any universal joint exceed 15º. The pump shaft and PTO shaft should be parallel.
(Figure 1)

HYDRAULIC PUMP DRIVE SHAFT INSTALLATION

The pump drive shaft included may be too long for some installations. It may be cut and redrilled as
necessary. When redrilling the shaft, be sure that universal joints are properly "timed", as shown in
Figure 1.
Install the slip joint at the end of the pump drive shaft. Failure to install the slip joint will result in
bearing failure in pump, PTO or both.
RADAR & CONTROLLER INSTALLATION

See control manual for installation instructions of radar, control box and cable routing.
