Auxiliary and Function Pump

How to Remove the Auxiliary
Pump or Function Pump
When removing a hose assembly
or fitting, the O-ring on the fitting
and/or hose end must be replaced
and then torqued to specification
during installation. Refer to
Section 2, Hydraulic Hose and
Fitting Torque Specifications.
1 Close the hydraulic shutoff valve located at the
hydraulic tank.
Component damage hazard. The
machine must not be operated
with the hydraulic tank shutoff
valve in the closed position or
component damage will occur. If
the tank valve is closed, remove
the key from the key switch and
tag the machine to inform
personnel of the condition.
2 Tag, disconnect and plug the hydraulic hoses
from the pump. Cap the fittings on the pump.
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.
3 Remove the pump mounting bolts from the
pump. Carefully remove the pump from the
electric motor.
