Motor (See Fig. 1-14)
The hydraulic motor is a dual displacement vane-type
motor for high-performance winches and single-displace-
ment for self-rescue winches. Full or half displacement is
selected at the motor by shifting an integral two position

spool. The default position is full displacement when
pressure is not signaled by the winch to the spool. Output
speed is proportional to input fl ow from the pump and
inversely proportional to the motor displacement.
