System Description
Fluid Flow Diagram
The system is a compact rotary-valve-type power steering, connected to the steering gearbox. The fluid pressure is pro-
vided by a vane-type pump which is driven by the engine crank pulley. The amount of fluid and pressure is regulated by
the flow control valve built into the pump. The fluid pressure from the pump is delivered to the valve body unit around the
pinion of the steering gearbox. The valve inside the valve body unit controls the hydraulic pressure and changes the direc-
tion of the tlow. The fluid then flows to the power cylinder, where rack thrust is generated. Fluid returning from the power
cylinder flows back to the reservoir, where the fluid is "filtered" and supplied to the pump again

Flow Control
The flow control valve in the pump performs the follow-
ing steps O through aE ro control the flow of fluid, i.e. to
increase the discharge volume when engine speed is
low and to decrease it when the engine speed increases
The assistance thrust of the steering gearbox changes in
compliance with the change in the discharge volume.
When the engine starts, fluid discharged from the
discharge port starts to run through the metering
ori{ice in the pump. The discharge volume increases
as the engine speed increases.
As the flow has already been regulated by the
metering orifice when the engine speed ls at or near
the idle speed, a constant and regulated amount of
fluid is discharged until the engine speed reaches
the middle speed range. As the engrne speed
increases, the pressure difference between the ends
of the metering orifice increases. A pressure differ-
ence is created between the top and bottom ends of
the flow control valve, too, pushing the flow control
valve to open the by-pass passage. This allows the
excess fluid to return to the inlet port preventing
pressure at the discharge port trom rising exces-
As the engine speed continues to increase, the flow
control valve is pushed back further' When the
engine speed reaches a given speed, the return pas
sage outside the melering orifice is connected to
the inlet port, and the opening to the inlet port
widens in prooortion to the increase in engine
speed. This makes part of the fluid regulated by the
metering orifice return to the inlet port of the pump;
there by discharged Iluid lrom the pump rs
decreased slowlv by this amount
The orifice in the return passage regulates and
maintains the flow of fluid discharged from the
pump at a given level untilthe engine speed reach-
es the high speed range.

Inspection and Adjustment
Pump Belt
NOTE: When using a new belt, first adjust the deflection
or tension to the values for the new belt, then readjust
the deflection or tension to the values for the used belt
after running engine for five minutes,
Inspection
Attach the soecial tool to the belt and measure the ten-
sion of the belt.
Tension:
Usad Belt: 390 - 54O N {/10 - 55 kgf. 88 - 120 lbf}
Nsw Belt: 740 - 880 N {75 - 90 kgf. 170-2(X)lbf)
NOTE:
. lf there are cracks or any damage evident on the belt,
replace it with a new one.
