Usage:
Separation Of Governor From Fuel Injection Pump Housing
start by:
a) remove fuel injection pump housing and governor
1. Install the fuel injection pump housing on tool (A).
2. Remove the bolts (1) that hold the governor housing (2) to the fuel injection pump housing.
3. Remove the governor housing (2).
4. Remove the two springs (4) and the seat (3) from the governor housing. Remove springs (4) from seat (3).
5. Remove spring (6), seat and piston assembly (9) and spring (8) from shaft (7).
6. Remove cover (5).
7. Remove the shaft (10) and the lever (11) from the pump housing.
8. Remove the thrust collar (13) from the shaft.
9. Remove the cover (12) from the pump housing.
10. Loosen the two bolts (14) that hold the torque spring assembly (15) and remove it from the pump housing.
11. Remove the pin (16) from the pump housing.
12. Remove the screw (18) and nut (19) from the pump housing.
13. Remove the ring that holds the lever and remove the lever (20) from dowel (17).
14. Remove the shield (21) from the camshaft with tool (B).
| NOTICE |
|---|
Pull on the shield only a small amount in each location, so it will not have distortion or damage. The shield is staked in place and can be damaged when removed. If the shield is damaged, a replacement must be made. |
15. Install the timing pin (C) to hold the camshaft.
16. Remove the bolts (22) that hold the flyweight assembly (23) to the camshaft.
17. Remove the flyweight assembly (23) from the camshaft.
Connection Of Governor To Fuel Injection Pump Housing
1. Put the fuel injection pump housing on the bracket assembly (A).
2. Install the timing pin (B) to hold the camshaft.
3. Put the flyweight assembly (1) in position on the camshaft.
NOTE: Be sure the pin that holds the shaft (2) is in position on the back of the flyweight assembly.
4. Install the bolts that hold the flyweight assembly to the camshaft and tighten to a torque of 10 ± 2 lb. ft. (13.6 ± 2.7 N·m).
5. Remove the timing pin (B).
6. Put the shield (3) in position over the flyweights.
7. Use the driver (C) to install the shield the remainder of the way on to the camshaft.
8. Put a new O-ring seal on the dowel (4) and install the dowel in the pump housing. Make the dowel even with the machined surface of the counterbore on the outside of the housing.
9. Put the lever (8) on the dowel (4) and install the ring that holds it on the dowel.
10. Install the screw (6) and the nut (7) in the pump housing.
11. Install the pin (5) in the pump housing.
12. Put the torque spring assembly (10) in position on the housing and tighten the two bolts (11) that hold it to the housing.
13. Install the cover (9) on the pump housing.
14. Put the thrust collar (13) in position between the flyweights. Lift the flyweights up with a piece of wire and push the thrust collar (13) forward.
15. Put the lever (14) in position in the housing and in the groove of the thrust collar (13). Put a new O-ring seal on the shaft and install the shaft (12) down through the housing and into the holes in lever (14).
16. Install the cover (18) on the pump housing.
17. Install the spring (15) on the shaft.
18. Install seat and piston assembly (16) on the shaft.
19. Turn spring (17) on the piston and seat until it just contacts the shoulders on the piston and seat. The piston and seat must be in alignment after spring (17) is installed. If not, remove the spring and install again.
20. Install the seat (19) and two springs (20) in the governor housing.
| NOTICE |
|---|
Both springs must make a full seat on seat (19) before installing in governor housing. If springs do not make a full seat, high idle speed will not be correct. Low idle governor surge can be caused by springs not making a full seat. It can also prevent getting a low idle setting with stability. |
21. Install the governor housing (21) on the pump housing.
end by:
a) make an adjustment of the fuel system setting ( See FUEL SYSTEM in TESTING AND ADJUSTING)
b) install fuel injection pump housing and governor
