d. Inspection.

(1) Examine the pilot valve plunger and its bore in the ball head for scoring and burrs. If slightly scored, the

area may be cleaned up with a fine India stone. Care must be used to prevent rounding off the edges of

the plunger.

(2) Examine the oil pump gears and driven gear bushing for excessive wear and damage.

(3) Examine the power piston and its cylinder (bore) in the governor housing for scoring and burrs. If slightly

scored, the areas lay be cleaned up with a fine India stone. Care must be taken to prevent stoning flat

areas and round off edges of the piston.

(4) Examine the ends of the power piston-to-terminal lever pin for wear and scoring. Also, check the pin seats

in the terminal lever and power piston for wear and scoring.

(5) Inspect the ends of the terminal lever cross pin and holes in the terminal lever for wear and scoring.

(6) Inspect the finished radius (thrust bearing contact surfaces) of the flyweights for excessive wear or flat

spots. The flyweights must operate freely on their support pins for satisfactory governor operation.

(7) Inspect the terminal lever and speed adjusting lever shaft bushings in the governor housing. If scored or

worn excessively, the bushings should be replaced.

(8) Check the speed adjusting lever retracting spring and the shut down and fuel rod springs for fractured coils.

(9) Examine gear teeth of the drive and driven shafts in the governor drive for chipping or scoring.

(10) Revolve bearings by hand to check for excessive wear, bind, or rough spots.

e. Repair. Governor repairs are accomplished by the replacement of defective parts.

f. Reassembly.
