Governor Assembly: Inspection
Check valves and bore for scoring. Check free length of springs. Measure clearance between seal ring and groove. See GOVERNOR SPECIFICATIONS table. With governor reassembled, apply less than 71 psi (5 kg/cm2 ) for no more than 5 seconds to oil passage between seal rings. Valve should move slightly and a vibrating sound should be heard.
