Gear Fluid Pressure Test

  1. Ensure steering pump pressure is within specification. To measure steering gear fluid pressure, open gauge valve completely. Increase engine speed to 1000-1500 RPM.
  2. Turn steering wheel from lock to lock. Measure steering gear fluid pressure. Ensure gear pressure is within specification. See HYDRAULIC SYSTEM FLUID PRESSURE SPECIFICATIONS  table. If pressure is not within specification, replace gear.
