Information:
28. Remove ring (57) and dashpot assembly (58). 29. Use tool (C) to remove snap ring (64). Remove ring (63) and spool (62).30. Remove seat (61) from spring (60) and remove spring (60) from seat (59). 31. Remove spring (overfueling spring) (65) and riser (66). 32. Remove ring (67), races (68) and bearing (69). Make a replacement of shield (70) any time it is removed.33. Use a screwdriver to remove shield (70) as shown. 34. Remove bolts (71) and carrier (72). 35. Remove dowels (73) and flyweights (75).36. Remove shaft (74) and the dowel from shaft (74). 37. Remove races (76) and bearing (77).Assemble Governor
Put clean oil on all parts before assembly. Be sure all oil passages are clear. 1. Install one race (76), bearing (77) and the other race on the camshaft in the fuel injection pump housing. 2. Put flyweights (75) in position on carrier (72) and install the dowels to hold the flyweights in place. The flyweights must move freely on the dowels and have 0.010 to 0.23 mm (0.0004 to 0.009 in) end play. 3. Install dowel (78) in governor shaft (74) and install the governor shaft in the carrier as shown. 4. Put carrier (72) in position and install bolts (71). Make a replacement of shield (70) any time it is removed.5. Install shield (70) on the carrier and use tool (D) to push the shield against its seat. Use a hammer and punch to move the metal (stake) two places on the side of the shield 180° 15° apart next to the holes in the shield. 6. Install race (68), bearing (69), race (68). Use tool (C) to install the ring on riser (66) as shown. 7. Install riser (66) and spring (overfueling spring) as shown. 8. Assemble the dashpot as follows:a. Install spring (60) on seat (59) and install seat (61) in spring (60).b. Put spool and ring (63) in position on seat (61) and use tool (C) to install snap ring (64). 9. Install dashpot assembly (58) as shown. 10. Install ring (57) in the lower groove in the governor shaft. Install sleeve (56), spring (54), sleeve (56) and bearing (55). Spring (54) is used to put a preload on the thrust bearing on the camshaft in the fuel injection pump housing. 11. Use tool (B) to hold spring (54) in compression and install ring (53) in the groove in the governor shaft. Remove tool (B). 12. Put lever (52) in position on the governor servo and install pin (50) to hold the lever in place. Use a hammer and chisel to move the metal (stake) four places 90° apart on the outside surface on both legs of the governor servo to hold pin (50) in place.13. Install the O-ring seal on sleeve (49). Install piston (51) and sleeve (49) as shown.14. Install valve (44) as shown. 15. Install one lockring (48) in the groove near the center of valve (44). Put sleeve (45), spring (broken link spring) (46)
Put clean oil on all parts before assembly. Be sure all oil passages are clear. 1. Install one race (76), bearing (77) and the other race on the camshaft in the fuel injection pump housing. 2.
