Remove bolts (8) and remove governor housing (9) from the fuel injection pump housing. 7. Remove high idle adjustment screw (11) and low idle adjustment screw (10) from the governor housing. Remove the high idle adjustment screw first. 8. Remove bolts (12) and torque control (13) from the governor housing. 9. Remove bolt (14) and the lock. Remove shaft (15) and lever assembly (16) from the governor housing.
Pin (19) holds spring (17) in compression. Use caution to prevent injury when pin (19) is removed. Release the tension in spring (17) slowly.
10. Remove pin (19), spring (17) and plunger (18) from the lever assembly. 11. Remove seal (21) from the governor housing. Use tooling (A) to remove the plug and bearings (20) from the governor housing. If a replacement of spring guide (22) is necessary see SPECIAL INSTRUCTION Form No. SMHS7356 - USE OF 6V22 TOOL GROUP FOR REPLACEMENT OF GOVERNOR SPRING GUIDE. 12. Remove seat, washer, wave-washers and governor spring (23) from the weight assembly. Remove spring washer (26) from the weight assembly.13. Remove bolts (24) and the lock that hold weight assembly (25) to the fuel injection pump housing. Pull the weight assembly out and to the side to disengage it from the rack. 14. Remove ring (27) and the dowel under the ring that holds seat (28) in place. 15. Remove seat (28), bolt (29) and spring (30) from the weight assembly. Remove washer (31) from spring (30). 16. Remove guide (32), the two races and bearing from the sleeve. 17. Remove the second dowel (33) that holds sleeve (34) in place and remove the sleeve. 18. Remove valve (37) from the weight assembly and cylinder (35).19. Remove lock (36) and make a separation of the weight assembly and cylinder (35). 20. Remove sleeve (38) and piston (39) from cylinder (35). Remove the O-ring seal from the sleeve.Assemble Governor
Put clean oil on all parts before assembly and be sure all oil passages are clear. 1. Install the O-ring seal on sleeve (2). Install piston (1) in sleeve (2). Install sleeve (2) in cylinder (3). 2. Install cylinder (3) in weight assembly (4) and install lock (5) to hold them together. 3. Install valve (7) through the cylinder and install sleeve (6) on the valve with the second hole in the sleeve in alignment with the hold in the valve. Install dowel (8) to hold the sleeve on the valve. 4. Install larger race (9), bearing (10), smaller race (11) and guide (12) on sleeve (8). Put the hole in guide (12) in alignment with the first hole in sleeve (8). 5. Install washer (16) in spring (13). Install bolt (17) in seat (14). Put spring (13) and seat (14) in position on guide (12) with the hole in seat (14) in alignment with the hole in guide (12). Install dowel (18) through seat (14) and guide (12). Install ring (15) on the seat to hold the dowel in place. 6. Install the weight assembly on the fuel injection pump housing with piston (1) engaged over the groove in rack (19). Install lock (20) and the bolts that hold the weight assembly to the fuel injection pump housing. 7. Install spring washer (26) on the bolt as shown.8. Install spring (25), one wave washer (24), flat washer (23), other wave washer (22) and seat (21) on the bolt as shown. 9. Put plunger (28) and spring (27) in position in lever assembly (30) and install pin (29) to hold the spring and plunger in place. 10. Dimensions (X) and (Y) are controlled by the depths of bearings (32) and (33) in the governor housing. Install bearings (32) and (33) with tooling (A). Install lever assembly (30) and shaft (31) in the governor housing. With lever assembly (30) pushed against bearing (33) on the detent side, the clearance [dimension (Y)] between the guide for the governor spring and lever assembly (30) must be approximately 2.49 mm (.098 in.). Push lever assembly (30) against bearing (32) on the other side. The clearance [dimension (X)] between the guide for the governor spring and lever assembly must be approximately 3.40 mm (.134 in.). If the measurements are not correct, remove the lever assembly and the shaft and move the bearings as necessary to get the correct measurement. After the bearings are installed, there must be approximately .38 mm (.015 in.) end play in the lever assembly. Remove the shaft and lever assembly.11. Install the plug on the detent side of the governor housing with tooling (A) to a depth of 2.3 0.5 mm (.091 0.20 in.). Install the lip type seal in the opposite side of the governor housing with tooling (A). Install the lip type seal with the lip toward the inside of the governor housing.12.
