Table 3-71. Anchor Winch Engine - Hydrostarter - Loss of Fluid
Pressure When Engine is Not Running - Troubleshooting.
MALFUNCTION
TEST OR INSPECTION
CORRECTIVE ACTION
1. Loss of fluid pressure when engine is not running.
Step 1.
Check for ambient temperature decrease.
A drop in temperature will decrease the nitrogen pressure. Adjust the
pressure as needed for cranking requirements by use of the hand pump.
Step 2.
Check engine driven pump check valves not holding.
Disconnect the return hose and inlet hose from the engine-driven pump.
Leakage from the inlet fitting means that both check valves are defective.
Leakage at the return fitting means that only outlet check valve is defective.
Replace the defective check valve assembly(s). Refer to paragraph 3-178.
Step 3.
Check for hand pump valves not holding.
Disconnect the inlet hose from the hand pump. Leakage from the inlet fitting
means that either the relief valve alone or both the inlet and outlet check
valves are defective. Stone and clean the ball seats in the pump body and
replace the balls and springs if necessary. Refer to paragraph 3-179.
Step 4.
Check for damaged seal ring in starter control valve shown by external
leakage.
Refer to Direct Support Maintenance.
