  1. Wash all parts in solvent and air dry. Blow out all passages. Inspect sleeve for wear or damage. Check for free operation in case bore. Check driven gear for looseness on sleeve.
  2. Ensure valve opening at entry and exhaust is .020" (.51 mm) minimum. Valve opening measurements are made with driven gear up and thrust cap down. Entry measurement is made with weights extended while exhaust is measured with weights inward.
