start by:a) remove fuel injection pump housing, governor, and governor drive as a unitb) remove governorc) remove shutoff control1. Remove the governor drive housing from the fuel injection pump housing with a hoist. Weight of governor drive for G379 is 80 lb. (36 kg); for G398 and G399 is 125 lb. (56 kg). Remove coupling.2. Remove ring, plunger, spring, and retainer for shutoff control. 3. Remove pin that holds shaft assembly. Remove lever (2), spring (4), key and shaft assembly (5). Remove the seal from housing.4. Remove governor drive pinion (3).5. Use tooling (A) to remove gear from thrust washer (1). Remove the bearing from housing. 6. Remove ring (9). Remove bolts, locks, and gear (8).7. Remove thrust plate (10) and shims. Keep shims together for installation. 8. Turn puller bolt (12) counterclockwise and remove drive gear (11).9. Remove locknut (6), gear (7) and key. Remove the drive shaft (13). Remove bearings for the shaft from the housing.Assemble Governor Drive Housing
1. Install the bearings (1) in housing with tooling (A). Put clean engine oil on bearings. 2. Install the drive shaft (2) and locknut, key and gear (3).3. Install the drive gear. Turn the puller bolt to hold gear on shaft. 4. Heat the thrust washer to a temperature of 250°F (120°C). Install bearing and gear (4) in housing. Push thrust washer over gear until washer is even with top of gear. There must be .015 to .045 in. (0.38 to 1.14 mm) end clearance. 5. Install seal (6) in housing with lip of seal to inside. Install lever and shaft assembly (5). Install spring, key and pin. Be sure the pin is engaged with groove in shaft and shaft turns freely. The spring must hook over the pin and around shaft lever.6. Install plunger, spring, retainer and ring for shutoff control.7. Install governor drive pinion (8). Install shims and thrust plate (7). Install bevel gear (10) and ring. End play of drive shaft with new parts is .005 to .009 in. (0.13 to 0.23 mm). Maximum permissible end play with used parts is .015 in. (0.38 mm). 8. Use the tool group (B) to check the clearance (backlash) between pinion and bevel gear (10). Make adjustment of backlash by removing or adding shims (9) behind thrust plate (7). Amount of free movement (backlash) between bevel gear and pinion must be .002 to .006 in. (0.05 to 0.15 mm).9. Install coupling on shaft. Fasten a hoist and install governor drive housing on the fuel injection pump housing.end by:a) install shutoff controlb) install governorc) install fuel injection pump housing, governor, and governor drive as a unit
