Put clean fuel on governor parts during assembly.1. Put flyweights (2) in position on the carrier, and install dowels (1) to hold them in place.2. Install the dowel in shaft (3). Install the shaft in the carrier. 3. Be sure dowel (4) in the shaft is engaged in the groove on the back of the carrier and that the dowel is in place when the carrier is installed on the camshaft. 4. Install timing pin (D) to hold the camshaft.5. Put flyweight assembly (5) in position on the camshaft, and install the bolts that hold it in place. Tighten the bolts to a torque of 10 1 N m (90 9 lb.in.). 6. Install one race (6), bearing (9), the other race (6) and ring (7) on riser (8). 7. Install riser (8) between the flyweights with the bearing in. 8. Put the shield in position over the flyweights. Use tool (B) to install the shield the remainder of the way on to the camshaft. Stake the metal at two places on the shield 180° 5° apart to hold the shield on the camshaft. 9. Put lever (10) in position on the dowel, and install the lockring to hold it in place. 10. Install pin (11) as shown. 11. Install contact (13), insulators (14) and shim (12) on torque control bar (15) as shown. 12.

Remove all extra thread lock from the seal and housing. Be sure the drain hole between the bushing and seal is open. 20. Use clean grease to hold O-ring seal (26) in position on the bottom of the governor housing. 21. Put lever (29) in position in the governor housing with a washer (27) on each side of the lever. Install shaft assembly (28) in the governor housing. Install the bolts that hold lever (29) to shaft (28). 22. Install seat (30) and governor springs (31) on the spring guide in the governor housing as shown. 23. Put the gasket and governor housing (32) in position on the fuel injection pump housing. 24.
