PISTON PUMP PRESSURE TEST AND ADJUSTMENT - CONTINUED
c.
Connect another hose to pressure tap (6) for
pump output located on top of bank valve (7).
Connect pressure gage to other end of hose
assembly.
427-B0956
d.
Run engine until normal operating temperature is reached (TM 5-3805-290-10).
e.
Raise lift arms slowly (TM 5-3805-290-10).
f.
Maximum signal oil pressure should be 3,450 50 psi (23,750 350 kPa). Maximum pump output pressure
should be 3,750 50 psi (25,850 350 kPa). Difference between two gages is margin pressure. Margin pressure
should be 290 15 psi (2,000 103 kPa).
g.
If margin pressure is correct, lower lift arms to ground. Stop engine (TM 5-3805-290-10). Remove diagnostic
equipment.
h.
If margin pressure is not correct, stop engine (TM 5-3805-290-10). Proceed to step 6.
