1-20. WINCH HYDRAULIC SYSTEM.
RESERVOIR. Contains oil which is used for winch lubrication and hydraulic control systems.
PUMP. Driven directly off the engine, the pump is responsible for the circulation of the oil.
MAGNETIC STRAINER. Oil is pulled from the reservoir and goes through the strainer before it enters
the lubrication system and the hydraulic control system. The strainer removes harmful large metallic
particles from the oil which could cause damage to the systems.
FILTER. Removes smaller harmful particles from the oil before the oil returns to the reservoir.
CONTROL VALVE. This valve responds to the winch control lever. When you move the lever, the
valve sends pressure oil to engage or disengage directional clutches which permit the drum to turn.
DRUM. The gears which turn the drum are powered by the transmission. The direction the drum turns
is controlled by moving the winch control Iever.
