Remove two bolts (25), cover (26), and the gasket. 16. Remove spring (27) and valve (28) from the rotary servo body.17. Remove bolt (29) and body assembly (30). 18. Remove three O-rings (31) and shaft assembly (32). 19. Separate shaft (36) from star gears (33) and (34).20. Remove key (35), if necessary. 21. Remove two bolts (38) and fuel transfer pump (37). 22. Remove eleven bolts (39) and drive housing (40). 23. Remove bolt and washer (41). Remove rack control bar (42). 24. Remove two bolts (43) and servo piston assembly (44). 25. Remove retaining ring (45), spring seat (46), link spring (47), rack control sleeve (48), and ring (49) from servo piston assembly (44). 26. Remove sleeve (52), piston (51), and valve (50) from servo piston assembly (44). Remove the O-ring seal from sleeve (52). 27. Remove two bolts (53) and pump drive gear (54). 28. Remove the bolt and plug (58) and rack link (57).29. Remove two bolts (56), support assembly (55) and the pin. 30. Loosen twelve washers (59) with tool (B). 31. Install two rack zero pins, tool (E) in the pump housing. Hold the racks against tool (E).32. Install tool (C) and compress the fuel pump spring. Remove twelve washers (59). 33. With the regulator racks held against tool (E) install tool (G), and remove twelve fuel injection pumps (60). Mark each fuel injection pump so the pump can be returned to the original location assembly. Do not handle or mark the internal finishes of the fuel injection pumps. This will cause damage to the pumps. 34. Mark for identification at assembly right and left hand rack regulators (61). Remove the rack regulators. 35. Remove six bolts (62), two bolts (63), the plate assembly, and the gasket from the fuel injection housing.
Typical Example36. Remove bypass valve (64) and the O-ring seal. If necessary, press out adapter (65). 37. Remove bypass valve assembly (66) from valve body (70).38.
