6B-2 POWER STEERING PUMP
DESCRIPTION AND OPERATION
GENERAL DESCRIPTION
The power steering pump is a multivaned hydraulic
pump. The serpentine accessory drive belt on the en-
gine drives the power steering pump. The power steer-
ing pump provides the hydraulic pressure to the power
steering gear.
The power steering gear uses the hydraulic pressure
to assist in steering the vehicle.
When steering conditions exceed maximum pressure
requirements, such as when the wheels are turned
against the stops, the pressure built up in the steeringgear exerts pressure on the spring end of the flow
control valve. The high pressure lifts the relief valve
ball from its seat and allows oil to flow through a trigger
orifice located in the outlet fitting. This reduce pressure
on the spring end of the flow control valve which then
opens and allows the oil to return to the intake side of
the pump. This action limits maximum pressure output
of the pump to a safe level.
No repair procedures are to be done on the internal
components of the power steering pump. The only ser-
viceable components of the power steering pump are
the power steering pump pulley and the pump itself.

DIAGNOSTIC INFORMATION AND PROCEDURES
POWER STEERING PUMP DIAGNOSIS
Foaming or Milky Power Steering Fluid (Air in Fluid)
Low Pressure Due to Power Steering Pump
Check for a scored housing bore.
Check for leakage at the valve rings or the seals.ChecksActionReplace the housing bore.
Repair the leak.
Bleed the system.
Low Pressure Due to Power Steering Gear
Check for internal leakage in the power steering pump,
causing an overflow.
Clean for a low fluid level.ChecksActionRepair the internal pump leakage.
Bleed the system.
Repair the internal pump leakage.
Bleed the system.
Cold temperatures will cause the air bubbles in the
system if the fluid level is low.
Check for an external leakage of the power steering
pump at the seals.
Check for a worn serpentine accessory drive belt.ChecksActionReplace the seals.
Repair the leak.
Bleed the system.
Replace the serpentine accessory drive belt.
Check for air in the power steering fluid.
Check for a low level of power steering fluid.
Check for a loose mounting of the power steering pump.ChecksActionPerform the checks listed in “Foaming or Milky Power
Steering Fluid (Air in Fluid)” above.
Repair any internal or external leaks.
Bleed the system.
Tighten the pump mounting to specifications.
