Fluid Pressure Testing

  1. Remove pressure hose from oil pump and attach adapter for pressure gauge (C3309E). Tighten to 22-29 ft.lbs. (30-39 N.m). Start engine and place thermometer in reservoir. Close the gauge valve fully 3 times to bleed air from gauge. Check fluid level and add if necessary.
  2. When oil temperature reaches 170°F (76.6°C) for type "A" pumps, or 122°F (50°C) for type "B" pumps, check pressure. With valve closed, type "A" pumps should read 1066-1210 psi (75-85 kg/cm2 ). Type "B" pumps should have a pressure of 925-1066 psi (65-75 kg/cm2 ).
  3. Valve open pressure for both types of pumps should be 142 psi (10 kg/cm2 ). Reinstall pressure hose, taking care not to twist hose or interfere with adjacent parts.
    CAUTION: Do not keep shut-off valve closed more than 3 seconds at a time. Do not keep steering wheel turned more than 10 seconds at a time.
