Information:
To prevent possible personal injury, care must be taken when pin (17) is removed. The spring and plunger behind pin (17) are under spring force.
11. Remove pin (17), the spring and the plunger from the control lever.12. Remove band assembly (18) from the lever assembly. 13. Remove two seals (20) and bearing (19) from the governor housing. 14. Remove spring (22) from governor bolt (21).15. Remove seat (23) from riser (24).16. Remove the dowel from riser (24).17. Remove riser (24) and governor bolt (21) as a unit from governor plate (25).18. Remove governor bolt (21) from riser (24). 19. Remove spring (27) and washer (26) from the sleeve.20. Remove sleeve (28) from the servo piston valve. 21. Remove ring (32), large race (31), bearing (29) and small race (30) from sleeve (28). 22. Remove lock (34) from flyweights (33).23. Remove flyweight (33) from the governor plate. 24. Turn the governor plate over, and bend locks (36) down. Remove bolts (37), bracket (35) and the servo piston assembly from the governor plate. 25. Remove dowel (43), lever (44) and the servo piston assembly from bracket (35).26. Remove pin (42) and piston (38) from sleeve (40).27. Remove valve (39) from piston (38).28. Remove O-ring seal (41) from sleeve (40). 29. Tap lightly on cylinder (45) to remove it from the governor plate. 30. Remove O-ring seals (46) from cylinder (45). 31. Use Tool (A) to remove retaining ring (47) from the gear assembly. 32. Remove ring (51), spring (50), drive assembly (48) and ring (49) from gear assembly (52). 33. Use Tool (B) to remove ring (53) from drive gear assembly (52). Remove drive gear assembly (52) from the governor plate. 34. If dowel replacement is needed remove dowels (55), (56) and (57) from the governor plate.35. Remove bearing (54) from the governor plate.Assemble Governor
1. If a replacement of the dowels in the governor plate is necessary, see the illustration for correct installation dimensions. 2. Install bearing (1) for drive gear (2) in governor plate (3) with Tooling (A) until it is 0.51 0.25 mm (.020 .010 in) below the top surface of the governor plate. 3. Put clean engine oil on the inside diameter of bearing (1). Install drive gear (2) in governor plate (3). 4. Turn governor plate (3) over, and install snap ring (4) that holds drive gear (2) in place. 5. Install O-ring seals (6) on cylinder (5). 6. Put clean engine oil on the O-ring seals on cylinder (5). Install cylinder (5) in the governor plate with the notch in the cylinder in alignment with the bolt hole in the governor plate as shown.7. Install the O-ring seal on sleeve (9).8. Put clean engine oil on piston (7), sleeve (9) and valve (8). Install sleeve (9) on piston (7) and valve (8) in piston (7) as shown.9. Install the servo piston assembly in cylinder (5). Valve (8), sleeve (9) and piston (7) are parts of the servo piston assembly. 10. Put lever (11)
