Pump Pressure Test with T/N 07406-001000A or T/N 07406-001A101

Special Tools Required
• P/S joint adapter (pump) 07RAK-S040110
• P/S joint adapter (hose) 07RAK-S040122
• 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 steering gearbox.
1. Check the power steering fluid level (see page
17-14).
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).

the gauge should read no more than 1,470 kPa

Do not keep the shut-off valve closed more
than 5 seconds or the pump could be
damaged by overheating.
If the pump is in good condition, the gauge should

read at least 8,140 8,820 kPa (83 90 kgf/cm ,
−
1,180 1,280 psi). A low reading means the pump
output is too low for full assist. Repair or replace
the pump.
