Measure pinion rotating torque using Tools to make sure that the
measured value is within the standard. Readjust if the value is
outside the standard. Replace steering gear assembly, if the
value is outside the standard after readjusting, or adjusting
screw rotating torque is 5 N·m (0.51 kg-m, 44 in-lb) or less.

Apply recommended liquid gasket to inner socket and turn pinion fully to left with inner socket installed to

Readjust adjusting screw angle if the measured value is outside
the standard.

• If reading is outside of the specification, readjust screw angle

with adjusting screw.

CAUTION:

• If reading is still outside of specification, or if the rotating torque of adjusting screw is less

than 5 N·m (0.51 kg-m, 44 in-lb), replace steering gear assembly.

• Never turn adjusting screw more than twice.
• Replace steering gear assembly when adjusting screw is removed or turned more than twice.

CAUTION:

Make sure that belt tension is normal before starting the following procedure.
1.

Connect the oil pressure gauge [SST: KV48103500 (J-26357)]
and the oil pressure gauge adapter [SST: KV48102500 (J-
33914)] between oil pump discharge connector and high-pres-
sure hose. Bleed air from the hydraulic circuit while opening
valve fully. Refer to

ST-31, "Inspection"

Start the engine. Run the engine until oil temperature reaches
50 to 80

C (122 to 176

F).

CAUTION:

• Leave the valve of the oil pressure gauge fully open while

starting and running the engine. If engine is started with
the valve closed, the hydraulic pressure in oil pump goes
up to the relief pressure along with unusual increase of oil
temperature.

• Be sure to keep hose clear of belts and other parts when

engine is started.

Fully close the oil pressure gauge valve with engine at idle and
measure the relief oil pressure.

CAUTION:

Never keep valve closed for 10 seconds or longer.

Open the valve slowly after measuring. Repair oil pump if the relief oil pressure is outside the standard.
Refer to
