1. Remove timing plug (1) from the flywheel housing. The starting motor is removed for better illustration of the timing plug.2. Use tool (A) and turn the engine crankshaft clockwise as seen from the front of the engine, until a 3/8"-16 NC bolt, 2 1/2 in. long can be installed in the flywheel through the timing hole. If the timing hole in the flywheel is turned too far, do not turn the engine crankshaft backward. Turn the engine crankshaft two full turns.3. When No. 1 piston is at top center compression position, the intake and exhaust rocker arms for No. 1 cylinder can be moved through the breather hole in the valve cover.4. If the rocker can not be moved, remove the timing bolt and turn the engine crankshaft 360° and install the timing bolt again. 5. Put tool (B) in the pump housing to hold the camshaft in the correct position for number one piston.6. Put the fuel injection pump housing and governor (2) in position on the engine. Install the three bolts and washers that hold it in position.7. Make sure the camshaft is in the correct position in the fuel pump drive gear. Install bolt (3) and washer. Tighten the bolt to a torque of 80 5 lb.ft. (110 7 N m).8. Remove tool (B) and the timing bolt. Install the timing plug in the flywheel housing.9. Put the cover over the fuel pump drive gear. Install the six bolts that hold the cover in position.10. Install the breather tube.11. Install the clip that holds the overflow tube to the frame.12. Connect the line to the governor and the fuel filter base.13. Connect the line to the fuel injection pump housing.14. Connect the rod to the governor control lever.end by:a) install fuel linesSeparation Of Governor From Fuel Injection Pump Housing
start by:a) remove fuel injection pump housing and governor 1. Put the fuel injection pump housing and governor in position on tool (A).2. Remove bolts (1) that hold the governor housing (2) to the fuel injection pump housing. 3. Remove governor housing (2).4. Remove two bolts (3) from the cover. Remove cover (4) from over the torque spring. 5. Remove spring (7), wave washer (6) and guide (5) from the governor housing.6. Remove gasket (8) from the governor housing. 7. Remove bolt (11) and nut (9) from the torque spring (10). Remove the torque spring.8. Remove pin (12) from the hole in the fuel injection pump housing. 9. Remove seat (15) and over fueling spring (16) from the shaft.10. Pull shaft (13) up and remove lever (14). 11. Remove riser (follower) (18) from the shaft.12. Remove ring and lever (17) from the dowel. 13. Remove cover (19) with tool (B). Tool (B) can cause damage to cover. Always inspect the cover for damage and install a new cover if needed. 14. Install timing pin (20) to hold the camshaft from turning.15. Remove three bolts (21) that hold the flyweight assembly in position.16. Remove flyweight assembly (22).17. Remove the timing pin from the fuel injection pump housing.Connection Of Governor To Fuel Injection Pump Housing
1. Put the fuel injection pump housing on tool (A).2. Install timing pin (1) to hold the camshaft from turning.3. Put flyweight assembly (2) in position on the camshaft.
Make sure the pin that holds the shaft in the flyweight assembly is in position before installing the flyweight assembly.
4. Install three new bolts that hold the flyweight assembly to the camshaft. The bolts for holding the flyweight assembly to the camshaft have a locking material on the threads. The bolts must not be used more then one time. 5. Install cover (3) over the flyweight assembly with tool (B). 6. Grind a taper on the bottom edge of a 1/8" screwdriver (4). Install the screwdriver through the bolt hole in the governor housing. The screwdriver must fit evenly against the flyweight assembly cover. Make a mark (stake) in four places around the cover in line with the groove in the camshaft.
Never install a used flyweight cover.
7. Put lever (7) on the dowel. Install ring (6).8. Install pin (5) in the fuel injection pump housing with the round edge down. 9. Put the riser (follower) (11) in position between the flyweights. Lift the flyweights up with a piece of wire and push the riser (follower) forward.10. Put lever (10) in position in the groove of the riser (follower) (11) and the ball end engaged in the sleeve shaft lever (8). Install shaft (9) that holds the lever in position.
If lever (10) is not installed correctly, the governor cannot operate and can cause the engine to over speed.
11. Install over fueling spring (14) and seat (13) on the shaft.12. Install the torque spring (12). Install the bolt and nut that hold the torque spring in position. 13. Install guide (18), wave washer (16) and spring (17) in the governor housing.14. Put a new gasket (15) on the governor housing. 15. Install cover (19) over the torque spring. Install the two bolts that hold the cover in position.16. Put the governor housing on the fuel injection pump housing. Install the bolts that hold the governor housing in position.end by:a) install fuel injection pump housing and governor
