(1) Dial gauge
3) Resistance to rotation of pulley
Service limit:
Maximum load: 9.22 N (0.94 kgf, 2.07 lb) 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
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-85, 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-

• 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.
