Test and Adjustment of Prestolite Hydraulic Pump (Refer to Figure 4)
(1) Test Equipment:
(a) Hydraulic pump and mounting base.
(b) Pressure gauge (0-1000 psi).
(c) Pressure gauge (0-3000 psi).
(d) Hoses with fittings to connect base and gauges.
(e) Power supply (14 VDC).
(f) Ammeter (0 to 100 amps)
(g) Fuse or circuit protector (100 amps).
(2) Test and Adjustment:
– NOTE –
Test gauges or gauges of known accuracy should be used when
performing the following tests.
(a) Connect the 0 to 1000 psi gauge to the low pressure port of the pump base.
(b) Connect the 0 to 3000 psi gauge to the high pressure port of the pump.base.
(c) Connect black lead of pump motor to the negative terminal of the DC power supply.
(d) Remove the filler plug located on the forward side of the pump and ascertain that fluid is
within 1/2 inch of the bottom of the filler plug hole. Should fluid be below this level, add
fluid, MIL-H-5606A, through the filler hole. Reinstall the filler plug and tighten.
– NOTE –
A small vent hole is located under the vent screw head. Retain
1/64 inch clearance between the screw head and the small vent
hole.
(e) Bleed air from the attached lines. (Lines may be bled by alternately connecting blue lead and
green lead to the positive terminal of the power supply until all air is exhausted.)
(f) Connect blue lead to positive terminal of power supply. Pump should operate and the high
pressure gauge should indicate a specific pressure, as given in Chart 2 (refer to 29-00-00).
(g) Disconnect blue lead. The high pressure reading should not drop more than 300 psi in five
minutes. High pressure may not be selected again for five minutes.
(h) Connect green lead to positive terminal of power supply. Pump should operate in reverse,
dropping reading on high pressure gauge to zero. The low pressure gauge should indicate
500 to 800 psi. Disconnect green lead. Both pressure gauges should indicate zero psi.
(i) Should it be necessary to check the pump motor, first connect the ammeter in the electrical
circuit with the positive terminal of the meter to the black lead and negative terminal of the
meter to the negative terminal of the DC power supply.
(j) Connect the blue lead from the pump motor to the positive terminal of the power supply.
With a high pressure indication on the pressure gauge, the ammeter should read 75 amperes
maximum. Disconnect the blue lead.
