DESCRIPTION AND OPERATION
POWER STEERING PUMP
On all vehicles equipped with power steering, the
hydraulic pressure for operation of the power steer-
ing gear is provided by a belt driven power steering
pump (Fig. 1). The TTA power steering pump is a
constant flow rate and displacement, vane type
pump.

In the event of a power steering pump drive belt
failure, manual steering control of the vehicle can
still be maintained. However, under these conditions,
steering effort will be significantly increased.

SPECIAL TOOLS
POWER STEERING PUMP
All vehicles equipped with power steering use a
remote mounted reservoir for the power steering
fluid. The power steering fluid remote reservoir is
mounted to the rear of the cylinder head on the pas-
senger side of the vehicle.
The service procedures for the TTA power steering
pump are limited to the areas and components listed
below. No repair procedures are to be done on
internal components of the TTA power steering
pumps.
• Repair of power steering fluid leaks from areas
of the power steering pump sealed by O-rings is
allowed (See Pump Leak Diagnosis). However power
steering pump shaft seal leakage will require
replacement of the pump.
• Power steering fluid reservoirs, related compo-
nents and attaching hardware.
• Power steering fluid reservoir filler cap/dipstick
assemblies.
Because of unique shaft bearings, flow control lev-
els or pump displacements, power steering pumps
may be used only on specific vehicle applications. Be
sure that all power steering pumps are only replaced
with a pump that is the correct replacement for that
specific application.
Hydraulic pressure is provided for operation of the
power steering gear by the belt driven power steering
pump id (Fig. 1). It is a constant displacement, vane
type pump. The power steering pump is connected to
the steering gear by a power steering fluid pressure
hose and return hose.
