Bodily injury hazard. This
procedure requires specific repair
skills, lifting equipment and a
suitable workshop. Attempting
this procedure without these skills
and tools could result in death or
serious injury and significant
component damage. Dealer
service is strongly 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.
Note: Perform this procedure with the engine off
and cool.

Electrocution/burn hazard.
Contact with electrically charged
circuits could result in death or
serious injury. Remove all rings,
watches and other jewelry.

Tag and disconnect the case drain hose at the
top of the pump. Cap the fitting on the pump.
Note: Placing the open end of the case drain hose
below the hydraulic oil level in the hydraulic tank will
result in excessive hydraulic fluid leaking from the
hose. Do not lower the open end of the case drain
hose to below the fluid level of the hydraulic tank
until the hose is plugged.
4
Tag, disconnect and plug the large hydraulic
pump supply hose at the pump. Cap the fitting
on the pump.
Note: Placing the open end of the pump supply
hose below the fluid level in the hydraulic tank will
result in excessive hydraulic fluid leaking from the

supply hose to below the fluid level of the hydraulic
tank until the hose is plugged.

Tag, disconnect and plug the high pressure
hose at the pump. Cap the fitting on the pump.
Bodily injury hazard. Spraying
hydraulic oil can penetrate and

the oil pressure to dissipate
gradually. Do not allow oil to
squirt or spray.
