Remove oil supply line for the turbocharger. Remove oil drain line for the turbocharger (140 only).5. Remove the bolt that holds breather pipe (3) to fuel injection pump housing.6. Remove the bolts (5) that fasten the fuel injection pump housing to the accessory drive housing.7. Remove the two bolts (4) that hold the fuel injection pump housing to the elbow.8. Remove the fuel injection pump housing and governor as a unit. Weight is 50 lb. (23 kg).Install Fuel Injection Pump Housing And Governor As A Unit
1. Turn crankshaft until No. 1 piston is at top center on compression position. See LOCATING TOP CENTER COMPRESSION POSITION FOR NO. 1 PISTON in TESTING AND ADJUSTING. Install the timing fixture plate (A) on rear face of the accessory drive housing.2. If plate (A) can be installed with dowels in housing in alignment with dowel holes in plate, the accessory drive shaft is in correct timing position, do step 7 next. If plate (A) can not be installed, do step 3 next.3. Remove the small cover from front of timing gear cover. Remove the nut and washer that fasten the timing gear to the shaft. 4. Use tool setup (B) to make a separation between the gear and shaft. Turn the shaft until plate (A) can be installed with dowels and holes in alignment. 5. Install the washer on shaft so the outside diameter of washer is against the gear. Install and tighten the nut to 100 10 lb.ft. (13,8 1,4 mkg).6. Install the cover on timing gear cover.7. Remove timing fixture plate (A) from housing. Put injection pump housing and governor into position, and install bolts.8. Turn the valve for fuel supply (at the tank) to the "ON" position. Install the side cover for the engine.9. Install the oil supply line and the oil drain line for the turbocharger (140 only).10. Install bolt that holds the crankcase breather pipe to fuel injection pump housing. Fasten the control linkage to governor.end by: a) install fuel injection linesSeparation Of Governor From Fuel Injection Pump Housing
start by: a) remove fuel injection pump housing and governor as a unit 1. Remove the cover (1).2. Remove the screw (2) from the rack stop collar.3. Remove rack stop collar (3). 4. Remove the bolts (4) that fasten the governor to the fuel injection pump housing.5. Remove the governor housing (5).6. Remove the governor spring and seat assembly from the guide in housing (5).7. Remove the washer-type spring (6) from bolt.8. Remove the three bolts (7) and lock that fasten the cylinder and weight assemblies (8) to the fuel injection pump housing.9. Pull the cylinder and weight assemblies straight out until they are free of dowels. 10. Slide the cylinder and weight assemblies to the side to free the piston from rack (9).Connection Of Governor To Fuel Injection Pump Housing
1. Put the cylinder and weight assemblies (1) in position on the fuel injection pump housing so the piston (2) is in correct position on the rack (3).2. Push the cylinder and weight assemblies on to the location dowels. 3. Install the three bolts (4) and lock.4. Install the washer-type spring (5) on bolt (6).5. Put the seat assembly and governor spring on guide in governor housing. The washer-type spring (5) should be installed so the inside diameter of spring will be against the guide in governor housing (7).6. Put the governor housing (7) in position on fuel injection pump housing, and install the bolts. 7. Install the rack stop collar (8) on bolt (6).8. Put the idle screw cover (10) in position on the governor housing so the dowel (11) in housing is engaged with slot (12) in the rack stop collar.9. Install the bolts that fasten the idle screw cover to the governor housing.end by: a) install fuel injection pump housing and governor as a unitb) make an adjustment to the rack and governor (See FUEL RACK SETTING AND GOVERNOR ADJUSTMENTS in TESTING AND ADJUSTING)
