Drive Pump
The drive pump is a bi-directional variable
displacement piston pump. The pump output is
controlled by the electro-proportional controller,
located on the pump. The only adjustment that can
be made to the pump is the neutral or null
adjustment. Any internal service to the pump
should only be performed at an authorized Eaton
Hydraulics center. Call Genie Industries Service
Department to locate your local authorized service
center.
How to Remove the Drive Pump
Component damage hazard. The
work area and surfaces where
this procedure will be performed
must be clean and free of debris
that could get into the hydraulic
system and cause severe
component damage. Dealer
service is recommended.
Note: When removing a hose assembly or fitting,
the O-ring (if equipped) on the fitting and/or hose
end must be replaced. All connections must be
torqued to specification during installation. Refer to
Specifications, Hydraulic Hose and Fitting Torque
Specifications.

the tank valves are closed,

Tag and disconnect and plug the hydraulic
hoses from the drive and function pumps. Cap
the fittings on the pumps.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and
burn skin. Loosen hydraulic
connections very slowly to allow
the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.

Support the pump with a lifting device and
remove the two drive pump mounting
fasteners.
