Pressure Test

CAUTION: DO NOT hold valve closed for more than 5 seconds as pump damage may result.

Disconnect high pressure line from pump. Connect Tool (J-5176-11) to pump. Using Pressure Gauge (J-5176-02), and Adapter Fitting (J-5176-12), connect gauge to other hose.
Open valve fully and run engine until fluid reaches normal operating temperature. Check fluid level and add, if necessary. When engine is at normal operating temperature, pressure reading on gauge (valve open) should be 80-125 psi (5.6-8.8 kg/cm² ).
If pressure is above 200 psi (14 kg/cm² ), check hoses for restrictions and poppet valve for proper assembly. Close valve on gauge fully 3 times. Record highest pressure attained each time.
If 3 pressures recorded are within 50 psi (3.5 kg/cm² ) of each other, pump is functioning properly. If 3 pressures are high, but do not remain within 50 p[psi (3.5 kg/cm² ) of each other, flow control valve in pump is sticking. If 3 pressures are constant, but more than 100 psi (7.0 kg/cm² ), or below 1350 psi (94.9 kg/cm² ), replace flow control valve and recheck.
If pump meets specification, leave valve open and turn steering wheel from stop to stop. Record highest pressures and compare with maximum pump pressure recorded.
If pressure is not alike (at both stops) as maximum pressure, steering gear is leaking internally. Shut off engine, remove equipment, check fluid level, or make necessary repairs.
