Auxiliary Pump
How to Test the Auxiliary Pump
The auxiliary pump is a 2-section, gear-type pump.
Pump number 1 is the pump section closest to
the pump motor and pump number 2 is the pump
section that is farther from the pump motor. Each
section of the pump has its own relief valve located
within the pump body.
Note: 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 Specifications,
Hydraulic
Hose and Fitting Torque Specifications.
1 Disconnect and plug the high pressure
hydraulic hose from pump number 1.
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.
2 Connect a 0 to 5000 psi / 0 to 345 bar pressure
gauge to the high pressure port on pump
number 1.
3 Turn the key switch to ground control and
pull out the Emergency Stop button to the
on
position.
4 Activate any function using auxiliary power.
Result: If the pressure gauge reads 2500 psi /
172 bar, immediately stop. The pump is good.
Result: If pressure fails to reach 2500 psi
/ 172 bar, the internal relief valve setting is
incorrect or the pump is bad and will need to be
serviced or replaced.
5 Turn the key switch to the
off
position.
6 Remove the pressure gauge and reconnect the
hydraulic hose.
7 Disconnect the hydraulic hose from the high
pressure port from pump number 2.
8 Connect a 0 to 5000 psi / 0 to 345 bar pressure
gauge to the high pressure port on pump
number 2.
9 Turn the key switch to ground control and
pull out the Emergency Stop button to the
on
position.
10 Activate any function using auxiliary power.
Result: If the pressure gauge reads 3000 psi /
207 bar, immediately stop. The pump is good.
Result: If pressure fails to reach 3000 psi
/ 207 bar, the internal relief valve setting is
incorrect or the pump is bad and will need to be
serviced or replaced.
11 Remove the pressure gauge and reconnect the
hydraulic hose.
How to Remove the Auxiliary
Pump
1 Open the ground controls side turntable cover.
2 Tag, disconnect and plug the hydraulic hoses
from the pumps.
3 Remove the pump mounting fasteners and
remove the pump from the pump motor.
