DESCRIPTION & OPERATION
NOTE: Some vehicles are equipped with Variable Effort Steering
(VES) system, identified by a solenoid on the power steering
pump at the pressure line outlet. See appropriate ELECTRONIC
article.
RACK & PINION ASSEMBLY
Pump pressurizes fluid and sends it through the pump’s flow
control valve to the pinion and valve on the rack and pinion assembly.
See Fig. 1. Pinion and valve direct fluid to either side of the piston
and rack, depending on turning direction of steering wheel. Piston and
rack converts hydraulic pressure into linear force, reducing turning
effort.
POWER STEERING PUMP
Two types of power steering pumps are used, CB series or TC
series. These pumps are constant displacement vane-type pumps. See
Fig. 4 and Fig. 5. When pressure exceeds set limits, a flow control
pressure relief valve opens, allowing fluid to return to the inlet
side of the pump. Some pump applications have remote fluid reservoirs
or reservoir attached to pump assembly, to enable different pump
mounting locations. Some models have a reverse rotation pump,
depending upon location and belt routing.
LUBRICATION
FLUID TYPE
Use GM Power Steering Fluid (1050017). Failure to use proper
fluid will cause hose and seal damage, resulting in fluid leaks and
