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 flow. 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.

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 beltafter running engine for five minutes.
Inspection
Attach the special tool to the belt and measure the ten-sion of the belt.

Measure the clearance between the gearbox andvalve body unit using a feeler gauge as shown.
NOTE: Measure the clearance at the point midwaybetween the two mounting bolts.
Determine the required thickness of the 32 mmshims by subtracting the clearance obtained in thestep "c" from the total thickness of the four shims.(Total thickness of the 4 shims) - (Clearance) =
Required thickness of the shims
NOTE: Select the shims so that the total thicknessis close to. but less than, the required thickness,

Example:
Measurement is 0.28 mm (0.011 in):0.70 - O.28 = 0.42 mm (0.028 - 0.011 = O.Ot7 inl
The selected shims should be 0.28 mm lO.OtO in) and0.15 mm {0.006 in} in thickness.
lf the r€quired shim thickness is 0.10 mm or less, noshims are necessarv.
