Power Assisted System (Power Steering)
2. SERVICE LIMIT
S601070A1001
Make a measurement as follows. If it exceeds the
specified service limit, replace the parts with new
ones.
CAUTION:
¼ Fix oil pump on a vise to make a measure-
ment. At this time, hold oil pump with the least
possible force between two wood pieces.
¼ Do not set outside of flow control valve or
pulley on a vise; otherwise outside or pulley
might be deformed. Select properly sized wood
pieces.

NOTE:
Read the value for one surface of V ditch, and then
the value for another off the dial.
(1) Dial indicator

3) Resistance to rotation of pulley

Service limit:
Maximum load; 9.22 N (0.94 kgf, 2.07 lb)
or less
NOTE:
¼ A rather higher value may be indicated when
pulley starts turning.
¼ Measure the load during rotation and make a
judgment.
(1) Spring balance

3. HYDRAULIC PRESSURE

CAUTION:
¼ Be sure to complete all items aforemen-
tioned in "INSPECTION", prior to measuring
hydraulic pressure. Otherwise, pressure can
not be measured correctly. <Ref. to PS-103
INSPECTION, General Diagnostic Table.>
¼ 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 damaged due to long keep of
these conditions.
¼ Put cotton cloth waste at a place where fluid
drops before pressure gauge is installed. Wipe
off split fluid thoroughly after the measure-
ment.
