Power Steering Pump: Testing and Inspection
Pump Pressure Test With T/N 07406-001000A or T/N 07406-001A101
Pump Pressure Test with T/N 07406-001000A or T/N 07406-001A101
Special Tools Required
^
P/S joint adapter (pump) 07ZAK-S7CA100
^
P/S joint adapter (hose) 07ZAK-S7CA200
^
P/S pressure gauge 07406-001000A or 07406-001A101
Check the fluid pressure as follows to determine whether the trouble is in the pump or gearbox.
1. Check the power steering fluid level.
2. Disconnect the pump outlet hose (A) from the pump outlet with care so as not to spill the power steering fluid on the frame and other parts, then
install the P/S joint adapter (pump) on the pump outlet (B) with the P/S joint outlet plate.
3. Connect the P/S joint adapter (hose) to the P/S pressure gauge, then connect the pump outlet hose to the P/S joint adapter (hose).
4. Install the P/S pressure gauge to the P/S joint adapter (pump).
5. Open the shut-off valve (A) fully.
6. Start the engine and let it idle.
7. Turn the steering wheel from lock-to-lock several times to warm the fluid to operating temperature at 158°F (70°C).
8. Measure steady-state fluid pressure while the engine is idling. If the pump is in good condition, the gauge should read no more than 1,470 kPa (15
kgf/cm2, 213 psi).
If it reads high, check for:
^
Clogged or deformed feed or return line between the pump and the gearbox.
^
Clogged valve body unit.
9. Close the shut-off valve gradually and read the pressure.
