Pump Pressure Test With T/N 07406-001000A
Pump Pressure Test with T/N 07406-001000A
-
Special Tools Required
-
P/S joint adapter (pump), 07RAK-S040110
-
P/S joint adapter (hose), 07RAK-S040121
-
P/S pressure gauge, 07406-001000A
Check the fluid pressure as follows to determine whether the trouble is in the pump or gearbox.
1. Check the power steering fluid level and pump belt tension.
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).
3. Connect the P/S joint adapter (hose) to the P/S pressure gauge, then connect the pump outlet hose (A) to the P/S joint adapter (hose).
4. Install the P/S pressure gauge to the P/S joint adapter (pump).
5. Open the pressure control 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.
8. Measure steady-state fluid pressure while the engine is idling. If the pump is in good condition, the gauge should read less than 1,500 kPa (15
kgf/ cm2, 213 psi). If it reads high, check for:
-
Clogged or deformed feed or return line between the pump and gearbox
-
Clogged valve body unit
9. Close the pressure control valve gradually and read the pressure.
