25. POWER STEERING PRINCIPLES
Power steering is a hydraulic device which utilizes engine power to reduce steering effort.
Consequently, the engine is used to drive a pump to develop fluid pressure, and this pressure acts
on a piston within the power cylinder so that the piston assists the rack effort. The amount of this
assistance depends on the extent of pressure acting on the piston. Therefore, if more steering
force is required, the pressure must be raised. The variation in the fluid pressure is accomplished
by a control valve which is linked to the steering main shaft.
NEUTRAL (STRAIGHT-AHEAD) POSITION
Fluid from the pump is sent to the control valve. If the control valve is in the neutral position, all
the fluid will flow through the control valve into the relief port and back to the pump. At this time,
hardly any pressure is created and because the pressure on the cylinder piston equal an both
sides, the piston will not move in either direction.
POWER STEERING
DESCRIPTION
-STEERING POWER STEERING
SR-24
26. SERVICE HINT
Troubles with the power steering system are usually concerned with hard steering due to the fact
that there is no assist. In such cases, before attempting to make repairs, it is necessary to
determine whether the trouble lies with the pump or with the gear housing. To do this, an on-
vehicle inspection can be made by using a pressure gauge.
ON-VEHICLE INSPECTION
Power steering is a hydraulic device and problems are normally due to insufficient fluid pressure
acting on the piston. This could be caused by either the pump not producing the specified fluid
pressure or the control valve in the gear housing not functioning properly so that the proper fluid
pressure can not be obtained.
If the fault lies with the pump, the same symptoms will generally occur whether the steering
wheel is turned fully to the right or left. On the other hand, if the fault lies with the control valve,
there will generally be a difference between the amount of assist when the steering wheel is
turned to the left and right, causing harder steering. However, if the piston seal of the power
cylinder is worn, there will be a loss of fluid pressure whether the steering wheel is turned to the
right or left and the symptoms will be the same for both.
Before performing an on-vehicle inspection, a check must first be made to confirm that the
power steering system is completely free of any air. If there is any air in the system, the volume
of this air will change when the fluid pressure is raised, causing a fluctuation in the fluid pressure
so that the power steering will not function properly. To determine if there is any air in the
system, check to see if there is a change of fluid level in the reservoir tank when the steering
wheel is turned fully to the right or left.
For example, if there is air in the system, it will be compressed to a smaller volume when the
WHEN TURNING
When the steering main shaft is turned in either direction, the control valve also moves, closing
1 of the fluid passages. The other passage then opens wider, causing a change in fluid flow
volume and, at the same time, a differential pressure is created between both sides of the piston.
Consequently, the piston moves in the direction of the lower pressure so that the fluid in the
cylinder is forced back to the pump through the control valve.
-STEERING POWER STEERING
SR-25
27. VANE PUMP
The main component parts of the vane pump, such as the cam ring, rotor, vanes and flow control
valve are high precision parts and must be handled carefully. Also, because this pump produces
a very high fluid pressure, O-rings are used for sealing each part. When reassembling the pump,
always use new O-rings.
In the flow control valve, there is a relief valve which controls the maximum pressure of the pump.
The amount of this maximum pressure is very important; if it is too low, there will be insufficient
power steering assist and if too high, it will have an adverse effect on the pressure hoses, oil
seals, etc. If the maximum pressure is either too high or too low due to a faulty relief valve, do not
disassemble or adjust the relief valve, but replace the flow control valve as an assembly.
The clearance between the flow control valve and pump body installation hole is very important.
After manufacture, the factory measures the size of the installation hole and outer circumference
of the flow control valve, and punches a mark accordingly. Therefore, when replacing the flow
control valve, be sure to do so with one having the same mark in order to insure the proper
clearance.
turned fully to the right or left.
If there is air in the system, it will be compressed to a smaller volume when the steering wheel is
turned, causing a considerable drop in the fluid level. If the system is free of air, there will be very
little change in the level even when the fluid pressure is raised. This is because the fluid, being a
liquid, does not change volume when compressed. The small change in the fluid level is due to
expansion of the hoses between the pump and gear housing when pressure rises.
Also, air in the system sometimes causes abnormal noise in the pump or gear housing when the
steering wheel is fully turned in either direction.
This on-vehicle inspection must be performed every time after overhauling or repairing the
pump or gear housing to ensure that the power steering is working properly.
-STEERING POWER STEERING
SR-26
28. The oil seals on both sides of the power cylinder are for the prevention of leakage of the high
pressure fluid which acts on the piston. Always use new oil seals when reassembling and be very
careful not to scratch or damage them.
Because of the high pressure, even the slightest scratch will cause fluid leakage, resulting in an
inoperative power steering system.
Also, be very careful not to scratch the sliding portion of the rack which makes contact with the
oil seals. When removing the rack ends from the rack, it is very easy to cause a burr when holding
the tip of the rack with a wrench. Therefore, before assembling the rack, first check the tip for
burrs and remove any with an oil stone.
Teflon rings are used for the piston and control valve. These teflon rings are highly durable
against wear, but if it is necessary to replace them, be careful not so stretch the new ones. After
installing a teflon ring into its groove, snug it down into the groove before assembly of the
cylinder or housing to prevent possible damage.
The functional parts of the pump which produce fluid pressure are the cam ring, rotor and vanes,
and these should be checked for wear. If the clearance between each is not within standard when
reassembling, any worn parts should be replaced.
In this case, the replaced cam ring and rotor should be of the same length (have the same mark),
and the vanes should be replaced with those having a length corresponding to that mark,
otherwise the proper thrust clearance cannot be obtained. If there is too much thrust clearance,
there will be insufficient fluid pressure at low speeds. If there is too little thrust clearance, it may
result in seizure of the vanes.
GEAR HOUSING
If the gear housing is secured directly in a vise during overhaul, there is danger of deforming it,
so always first secure it in the SST provided (rack and pinion steering rack housing stand) before
placing it in the vise.
-STEERING POWER STEERING
SR-27
29. IDLE-UP DEVICE
The pump produces the maximum fluid pressure when the steering wheel is turned fully to the
right or left and, at this time, there is a maximum load on the pump which causes a decrease in
engine idle rpm. To solve this problem, vehicles are equipped with an idle-up device which acts
to raise the engine idle rpm whenever there is a heavy load on the pump.
On EFI engines, when the piston of the air control valve is pushed by fluid pressure, the air valve
opens and the volume of air by-passing the throttle valve is increased to regulate engine rpm.
As with the rack and pinion type steering, preload is very important. If the preload is not correct,
it could result in such trouble as steering wheel play or shimmy or lack of durability, so always
make sure that it is correct.
