Hydraulic Pump Overhaul
The manufacturer of the hydraulic pump and fan motor requires that overhaul of the pump and motor
be accomplished only by personnel trained and experienced in hydraulic system mechanics and main-
tenance. Warranty considerations may be voided if work is done by unqualified personnel. Detailed
written instruction of the type and nature of that provided for the power steering gear has not been made
available for the disassembly, repair, inspection, and reassembly of the hydraulic pump and fan motor.
It is recommended that neither the hydraulic pump nor the hydraulic
fan motor be disassembled by maintenance personnel until and unless
such personnel have been familiarized with the specific details and
techniques of the maintenance procedures on these units. Failure to
follow all proper procedures may result in damage to the equipment
with the possibility of steering or cooling system failure.
These two components require hydraulic system expertise and close attention to detail in order to ac -
complish overhaul and repair with reasonable assurance that the completed device will perform accord-
ing to expectation.
A seal and gasket kit is available from the Gillig Parts Division to use in minor overhauls of the pump or
fan motor. The user is cautioned that even this kit should be used only by those mechanics and mainte-
nance personnel who are experienced in, and familiar with, hydraulic systems and their components.
Accordingly, Gillig Corporation, in this manual, will limit repair and maintenance procedures to removal
and installation of the two components.
