2) Ditch deflection of pulley
Service limit:
1.0 mm (0.039 in) or less
NOTE:
Read the value for one surface of V ditch, and then
the value for another off the dial.
(1) Dial gauge
3) Resistance to rotation of pulley
Service limit:
Maximum load: 9.22 N (0.94 kgf, 2.07 lbf) or
less
NOTE:
• A rather higher value may be indicated when pul-
ley starts turning.
• Measure the load during rotation to make a judg-
ment.
(1) Spring balance
Oil Pump
POWER ASSISTED SYSTEM (POWER STEERING)
3. HYDRAULIC PRESSURE
NOTE:
• Be sure to complete all items aforementioned in
"INSPECTION", prior to measuring hydraulic pres-
sure. Otherwise, pressure cannot be measured
correctly. <Ref. to PS-92, INSPECTION, General
Diagnostic Table.>
• Do not leave the valve of pressure gauge closed
or hold the steering wheel at stop end for 5 seconds
or more in any case, as the oil pump may be dam-
aged due to long keep of these conditions.
• Put cloth at a place where fluid drops before
pressure gauge is installed. Wipe off spilt fluid thor-
oughly after the measurement.
1) Regular pressure measurement
(1) Connect ST1, ST2 and ST3.

ST2 34099AC020 ADAPTER HOSE B
ST3 34099AC010 ADAPTER HOSE A
(2) Remove the air intake duct.
(3) Disconnect the pipe C from pump.
(4) Using the gasket (Part No. 34621AC021)
and bolt (Part No. 34620AC010), install the ST2
to pump instead of pressure hose.
