5. Lower the front wheels.
6. Connect one end of a vinyl tube of suitable length to the
breather plug of the gear box, and place its other end in a
container.
7. Start the engine and idle it.
8. Loosen the breather plug, and then turn the steering
wheel completely to the right and left continuously until air
bubbles no longer appear in the fluid coming out of the
tube.
Caution
Do not hold the steering completely to the left or right
for IO seconds or more.
9. After completion of the bleeding, tighten the breather
plug. Check the fluid level. and refill if necessary.
10. When turning the steering wheel right and left fully, check
that the fluid level variation is less than 4 mm (.I6 in.)
OIL PUMP PRESSURE TEST
OIL PUMP PRESSURE TEST IV,sFLm.
1. Disconnect the pressure- hose from the oil pump and
connect the special tool as illustrated.
NOTE
Use the adaptor to connect the special tool to the pump.
2. Bleed the power steering system.
3. Start the engine and operate it until the fluid temperature
reaches about 55°C (131°F).
4. Run the engine at 1,000 r/min.
5. Completely close the shut-off valve of the special tool and
read the gauge pressure.
Caution
Do not close the shut-off valve of the special tool for
more than 3 seconds.
Standard value :
Valve closed 7,500-8,200 kPa (1,067-1,166 psi.)
Valve opened 980 kPa (142 psi)
Limit :
Valve opened 1,500 kPa (218 psi)
6. If the hydraulic pressureis not within the range of the
standard value, replace the oil pump.
7. Completely open the shut-off valve of the special tool and
read the gauge pressure. If the hydraulic pressure is not
within the range of then standard value, check for a
clogged or collapsed oil line, or for a clogged oil passage
inside the gear box.
8. With the shut-off valve of the special tool completely
open, and turn the steering wheel completely to the right
or left, then measure the maximum oil pressure in this
condition. If the maximum oil pressure is not within the
range of the standard value, (valve closed) the valve of the
gear box is faulty, and the gear box must be replaced.
