Pump
1. Disconnect the power steering pressure hose from the steering gear. Allow fluid to drain into the drain pan.
2. Unclip the power steering pressure hose from the retainer on the frame, and position the hose upward.
3. Install the analyzer fitting into the steering gear.
4. Install the analyzer fitting into the power steering pressure hose that was removed from the steering gear.
5. Hook up the power steering analyzer in series between the two power steering analyzer fittings.
6. Fill the system.
CAUTION: Make sure the valve on the power steering system analyzer is open, allowing the system to function normally.
7. Place the dial thermometer in the power steering oil reservoir.
8. With the engine running, raise the fluid temperature to 50-60° C (122-140° F) by turning the steering wheel fully left and fully right several times.
CAUTION: Do not hold the steering wheel against the stops for an extended period of time. Damage to the pump can occur.
9. Measure the power steering pump output pressure by closing the valve and increasing the engine speed to 1000-1500 rpm.
CAUTION: Do not leave the valve on the power steering analyzer closed for more than 15 seconds.
10. If the pressure recorded is lower than the minimum specified pressure, replace the pump. If the pressure is too high, inspect for a kinked hose and repair as necessary.
11. Increase engine speed from idle to 2500 rpm. If the flow exceeds the maximum free flow specified, replace the power steering pump.
12. Measure the pressure generated at the steering gear by leaving the valve on the analyzer open and increasing engine speed to 1000-1500 rpm. Turn the steering wheel fully left or fully right and read the pressure.
13. If the pressure is not within specifications, replace the steering gear.
^ Min Flow @ 740 psi and
76° C ± 15° C is 5.3 LPM.
170° F ± 5° F is 1.4 GPM.
^ Minimum Pressure Relief is 960 kPa (1400 psi)
^ Maximum Pressure Relief is 10550 kPa (1530 psi)
