1-88. HYDRAULIC STARTING SYSTEM - ANCHOR WINCH COMPARTMENT.
a. The Anchor Winch Compartment (Figure FO-29) contains a Hydraulic Starting System for the Anchor Winch
Engine. The Hydraulic Starting System is used for cranking internal combustion engines. The system is automatically
recharged after each engine start. It can also be manually recharged in an emergency. The ability to start does not
decrease after sitting for a long time. Hot or cold climates do not have nay harmful effects upon the Hydraulic Starting
System.
b. The Hydraulic Starting System (Figure 1-71 ) consists of a reservoir, an engine-driven charging pump mounted
on the anchor winch engine, and a hand pump with pressure gage. It also consists of two piston type accumulators with
pressure gages, a starting motor, high and low pressure filters, connecting hoses and fittings, and solenoid valves with
manual overrides.
c.
Hydraulic fluid flows by gravity or slight vacuum from the reservoir to engine-driven pump inlet or the hand
pump inlet. The hand pump is to supply the initial charge or to recharge the system. The fluid is discharged from the
pump outlet at a high pressure and flows into the accumulator. There it is stored at 3250 psi (228497.8 gm sq cm) under
the pressure of compressed nitrogen gas. When the starter is engaged and the control valve is opened, the expanding
nitrogen gas forces the fluid out of the accumulator at a high pressure. It then flows into the starting motor which quickly
speeds up the engine to a high cranking speed. The fluid returns from the starter to the reservoir.
