Replace shield any time it it is removed. 42. Remove the bolts and carrier assembly (71) from the fuel injection pump housing. 43. Remove governor shaft (74) from the carrier assembly. Remove dowel (75) from the governor shaft.44. Remove dowels (72) and flyweights (73) from the carrier assembly. 45. Remove races (76) and (78) and bearing (77) from the fuel injection pump housing.Assemble Governor
1. Put the fuel injection pump housing in position on tool (A).2. Install race (3), bearing (2) and race (1) on the end of the camshaft in the fuel injection pump housing. 3. Put flyweight (4) in position on carrier assembly (5), and install the dowels.4. Use a feeler gauge to check flyweight end play. The flyweights must move freely on the dowels and have 0.01 to 0.23 mm (.0004 to .0090 in.) end play. 5. Install dowel (7) in the governor shaft (6), and install the governor shaft in carrier assembly (5).6. Install carrier assembly (5) and the bolts on the end of the camshaft. Replace shield (8) any time it is removed.7. Use tool (B), and install shield (8) on the carrier assembly until it is against its seat. Use a hammer and punch to stake two places on the side of the shield 180° 5° apart next to the holes in the shield. 8. Install race (10), bearing (12), race (9) and ring (11) on riser (13). 9.
