HYDRAULIC STARTING SYSTEM - ANCHOR WINCH COMPARTMENT (Cont)
a. The charging pump runs all during engine operation, recharging the accumulator with fluid. A pressure
operated unloading valve in the pump opens and returns the pump discharge to the reservoir when the proper amount of
fluid has been returned to the accumulator.
b. The reservoir is a steel tank with a fine mesh screen at the outlet. The filler cap contains a filter to stop dust
and dirt from entering the reservoir.
c. The engine-driven charging pump is a single piston, positive displacement type. It should run at
approximately engine speed. The pump contains ball check valves and an unloading valve operated by the accumulator
pressure. The operation is completely automatic and operates in either direction of rotation.
d. The hand pump is a single piston, double-acting, positive displacement type. Flow through the pump is
controlled by ball check valves. A manually operated relief valve is provided so the accumulator pressure may be relieved
when any servicing is required.
e. The piston-type accumulator is precharged with nitrogen through a small valve. A seal ring between the
piston and the shell prevents the loss of gas into the hydraulic system. The accumulator is supplied with the proper
precharge.
f. The starter mounts on the flywheel housing. It has a pinion gear with an overrunning clutch for engaging the
flywheel ring gear. Movement of the starter control lever engages the pinion and opens the control valve. The motor is a
multi-piston, swash plate type.
