CONTROL GP-ELECTRONIC 4334675 - Caterpillar

1. Put the fuel injection pump housing on bracket assembly (A).2. Install timing pin (C) to hold the camshaft. Be sure the pin that holds shaft (22) is in position on the back of the flyweight assembly.3. Put flyweight assembly (21) in position on the camshaft.4. Install the bolts that hold the flyweight assembly to the camshaft and tighten them to a torque of 13.6 2.8 N m (120 24 lb in) for earlier governor and 10.2 1.1 N m (90 10 lb in) for later governors with thin bolt heads.5. Remove timing pin (C). 6. Put shield (19) in position over the flyweights. 7. Use driver (D) to install the shield the remainder of the way on to the camshaft. Move the metal (stake) at two places on the shield 180° 5° apart to hold the shield on the camshaft. 8. Put a new O-ring seal on dowel (17) 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 lever (18) on dowel (17) and install the ring that holds it on the dowel.10. Install screw (14) and nut (16).11. Install pin (15). 12. Put torque spring assembly (12) in position on the housing and install bolts (13). 13. Install cover (10).14. Put thrust collar (11) in position between the flyweights. Lift the flyweights up with a piece of wire and push thrust collar (11) forward. 15. Put lever (9) in position in the housing and in the groove of the thrust collar. Put a new O-ring seal on the shaft and install shaft (8) down through the housing and into the holes in lever (9). 16. Install cover (3).17. Install spring (6) and seat (7).
Both springs must make full contact on seat (5) before they are installed in the governor housing assembly. If the springs do not make full contact on the seat, high idle speed will not be correct and low idle governor surge can be the result. Low idle setting without stability can also be the result.
18. Install seat (5) and two springs (4) in the governor housing.19. Install governor housing (2) and bolts (1).End By:a. make an adjustment of the fuel system setting (See Fuel System in Testing & Adjusting)b. install fuel injection pump housing & governorSeparate Fuel Injection Pump Housing & Governor (Serial Numbers 90N6121-Up, 75V1-Up)
Start By:a. remove fuel injection pump housing & governor 1. Install the fuel injection pump housing on tool (A).2. Remove bolts (1) and governor housing (2). 3. Remove two springs (4) and seat (3). 4. Remove spring (6), seat and piston assembly (9), and spring (8) from shaft (7).5. Remove cover (5). 6. Remove shaft (10) and lever (11). 7. Remove thrust collar (13).8. Remove cover (12). 9. Remove two bolts (14) and torque spring assembly (15). 10. Remove pin (16).11. Remove screw (18) and nut (19).12.
