Information:

Use Again - if wear on contact surfaces cannot be felt with a seal pick.

Use Again - if wear on contact surfaces cannot be felt with a seal pick.Riser Shaft and Pin
Illustration 47 g06346580
Riser shaft.
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.
Illustration 48 g06346583
Normal wear on pin at end of riser shaft.
Use Again
Illustration 49 g06346588
Pin with material eroded away near the center relief.
Do Not Use AgainFlyweight and Dowel
Illustration 50 g06346593
Flyweight toe with gouges near dowel hole.
Do Not Use Again - if wear marks can be felt with a seal pick.
Illustration 51 g06346599
Flyweight toe wear.
Do Not Use Again
Illustration 52 g06346602
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.
Illustration 53 g06346609
Acceptable wear on flyweight dowel.
Use Again - if wear cannot be felt with a seal pick.
Illustration 54 g06346611
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
Illustration 55 g06346614
The bearing (white collar) shown in position on the FARC diaphragm retainer (Type V, VI, and VII Governors) shows wear.
Do Not Use AgainGovernor Spring Seat
Illustration 56 g06346615
Governor spring seat with typical wear.
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.
