Idle Pressure Test

Remove high pressure hose at steering pump and connect spare hose to pump fitting. Connect opposite end of spare hose to Pressure Test Gauge (C-3309E). Connect pressure hose from valve side of steering gear to valve side of gauge. Valve must be installed on outlet side of gauge. See Fig 1 .

NOTE: Replacement fittings are required on Pressure Test Gauge(C-3309E) for adapting to "O" ring type hose tube ends.
Fully open shutoff valve on test gauge. With thermometer in fluid reservoir, start engine and warm fluid to 150-170°F (66-77°C). Turning wheels from stop-to-stop will aid in warming fluid. DO NOT hold wheels against stop.
With engine at idle speed and gauge valve open, check initial pressure. See POWER STEERING PUMP PRESSURE TEST SPECIFICATIONS table. If pressure is more than 125 psi (9 kg/cm² ), check for restricted hoses or crimped lines. Repair as necessary.

POWER STEERING PUMP PRESSURE TEST SPECIFICATIONS

Application	Pressure - psi (kg/cm² )
Idle Pressure	50-80 (3.5-5.6)
Relief Pressure	1200-1300 (84.4-91.4)

CAUTION: DO NOT leave shutoff valve closed or force pump to operate against stops for more than 5 seconds. Pump damage will result.
