Use Again - if there is no wear step on the shaft, which can be felt with a seal pick. If a step is present, it will generally occur near the center of the shaft.

Flyweight toe wear.
Do Not Use Again - if there are any signs of "flat spots". Worn flyweight toes may be highly polished so that flat spots are difficult to feel. Hold the flyweight toe surface in bright light and watch for changes in reflection in worn areas. Use a new flyweight toe for comparison.

Acceptable wear on flyweight dowel.
Use Again - if wear cannot be felt with a seal pick.

Heavy wear on flyweight dowel.
Do Not Use AgainNote: Examine the dowel seating area on the flyweight carrier. If there is any apparent wear, reinstall dowels in the unused positions, 90 degrees from original position.Bearing Assembly

Use Again - if there are no gouges to surfaces (1) on the spring seating area.Spring Pack
Illustration 57 g06346618
End view of governor spring pack.
Use Again - after realignment.Note the off-center position of the internal springs with respect to the outside spring. This can cause governor instability, which results in surging. Rotate the springs on their seat so that the inner springs are aligned (centered) with respect to the outer spring. Remove sharp edges (A) from the inside diameter of the flat surface on the springs to ensure springs seat properly.
