Assemble Governor
1. Install detent plunger, spring and pin in levers.2. Install bearings in each side of the governor housing with tooling (A).3. Install levers and shaft in governor housing. The position of the bearings can make a difference in the position of the levers. With the levers pushed against the bearings on the boss side, clearance (X) between the guide for the governor spring and levers must be approximately .135 in. (3.43 mm). With levers pushed against other side the clearance (Y) on the other side must be approximately .100 in. (2.54 mm). If the measurements are not correct make an adjustment to the bearings in the governor housing.4. Install the bolt and lock.5. Install the speed limiter plunger, spring and plug in the governor housing.6. Install the high idle screw and low idle screw. 7. Install the O-ring seal (3) on sleeve (4).8. Install piston (2) and sleeve (4) in cylinder (1). 9. Put weight assembly (6) in place on cylinder (7) and install retaining ring (5). 10. Install valve (9) in piston (10).11. Install the bearing, races and retaining ring on the sleeve. Install the bearing assembly (8) on the valve (9). 12. Put seat (12), bolt (11), washers and spring in place on valve (9). Install pin (14) and ring (13).end by: a) connection of governor to fuel injection pump housingb) make adjustments to rack and governor (See FUEL RACK SETTING AND GOVERNOR ADJUSTMENTS in TESTING AND ADJUSTING
