Power Steering Pump: Description and Operation
Hydraulic pressure is provided for operation of the power steering gear by a belt driven power steering pump. The power steering pump is a constant
flow rate and displacement, vane-type pump. The internal parts in the housing operate submerged in fluid. The flow control orifice is part of the high
pressure line fitting. The pressure relief valve inside the flow control valve limits the pump pressure. The reservoir is separate from the pump. It is
mounted to the fan shroud.
The power steering pump is connected to the steering gear by the pressure and return hoses. The pump shaft has a pressed-on drive pulley that is belt
driven by the crankshaft pulley.
NOTE: Power steering pumps have different pressure rates and are not interchangeable with other pumps.
