Lift/Steer Pump
How to Remove the
Lift/Steer 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 Two,
Hydraulic
Hose and Fitting Torque
Specifications.
1 Locate the two hydraulic tank valves at the
hydraulic tank through the access hole
underneath the turntable, then close the valves.
Component damage hazard. The
engine must not be started with
the hydraulic tank shutoff valves in
the
CLOSED
position or component
damage will occur. If the tank
valves are closed, remove the key
from the key switch and tag the
machine to inform personnel of the
condition.
2 Tag, disconnect and plug the lift/steer pump
hydraulic hoses. 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. Carefully
remove the pump.
Component damage hazard.
Be sure to open the two hydraulic
tank valves and prime the pump
after installing the pump.
