- Check the power steering fluid level (see «Fluid Replacement»(ref-171165-S30156302182005012800000) ) and pump belt tension (see «Pump Belt Inspection and Adjustment»(ref-171165-S40639405972005012800000) ).
- 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. Wipe off any spilled fluid at once. Install the P/S joint adapter (pump) on the pump outlet (B) with the P/S joint outlet plate.
- 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).
- Install the P/S pressure gauge to the P/S joint adapter (pump).
- Fully open the shut-off valve (A).
- Fully open the pressure control valve (B).
- Start the engine and let it idle.
- Turn the steering wheel from lock-to lock several times to warm the fluid to operating temperature at 158°F (70°C).
- 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 (15kgf/cm2 213 psi). If it reads high, check for Clogged of deformed feed of return line between the pump and gearbox Clogged valve body unit
- Close the shut-off valve, then close the pressure control valve gradually until the pressure gauge needle is stable Read the pressure. NOTE: Do not keep the pressure control valve closed more than 5 seconds or the pump could be damaged by over heating.
- Immediately open the shut off valve fully If the pump is in good condition, the gauge should read at least 8,300-8,800 kPa (85-90 kgf/cm2 1,210-1,280 psi). A low reading means pump output is too low for full assist. Repair or replace the pump.
