System Pressure Test
- Install pressure gauge (US1074/2 ) between pressure hose and pressure pipe of valve housing, with pressure gauge valve open. Run engine at idle. Turn steering wheel lock-to-lock several times.
- Pressure should be 986-1189 psi (69-84 kg/cm2 ) on Quantum. All other models should be 1100-1200 psi (77.33-84.36 kg/cm2 ). If pressure is not within limits, check pump pressure. If pump is good, replace steering gear.
