Inspection
1. Check the plate assembly (8) composed of a ribbon spring
and coil spring for cracks and any other damage.
2. Check the valve shaft for wear, and also make sure that it
rotates smoothly when mounted in the body.
3. Check the piston for damage. Check also the valve fit-in
section of the shaft for damage.
4. Grease packed needle bearings are press-fitted at both
ends of the valve shaft hole of the governor body. Avoid
cleaning the body in gasoline or any other solvent.
