Hydraulic System
Connect a 1500 psi (100 kg/cm2 ) pressure gauge to power steering pump pressure line. Start engine and let idle. Turn steering to full lock. Exert pressure on steering gear. Pressure should be 1100-1200 psi (77.5-84.4 kg/cm2 ). See Fig 1 .
NOTE:
If pressure is less than 1100 psi (77.5 kg/cm2
) at idle, but rises with engine speed increase, problem is either a defective pump control valve or internal leakage in rack and pinion.
