NOTE: This is NOT NORMAL
. The piston shoes should always remain in contact
with the swash plate. The causes of and correction for this problem are the same as
for cavitation above.
With the pressure gauge still installed in the suction line at the pump inlet port, install
a second gauge (0-50 psig pressure gauge) in the case drain line at the pump case
port. Next, engage the PTO and operate the genset with no load for twenty minutes
to purge air out of the fluid. Note both gauge readings. If the differential pressure at
the case is greater than 7 psig, the suction side plumbing will require evaluation.
Note the following pressure measurements!
Inlet pressures:
Should always be positive.
Outlet pressure:
Approximately 500 psig with no load on the generator.
Note:
If
the gauge is fluctuating, record limits.
Case drain pressure to inlet pressure differential:
The difference between pump
inlet pressure and case drain pressure should not exceed 7 psig. Pump inlet pressure
minus case drain pressure should never be less than 7 psig.
Verify the installation of the following hydraulic generator hose diameters:
a.
Inlet hose (suction) on hydraulic pump (attaches to Port “S” on back of pump): 1
inch
b.
Outlet hose (pressure) on hydraulic pump (attaches to Port “B” on back of pump):
1/2 inch
c.
Case drain to hydraulic pump (attaches to Port “L” top side, mid-length of pump):
5/8 inch
Note:
The hose diameter appears in print along the length of the hose.
