Information:
1. Disconnect two fuel lines (1) from the transfer pump.2. Disconnect three lines (2) from the fuel injection pump housing and air-fuel ratio control. 3. Remove bolt (3) from the governor linkage.4. Remove three bolts (5) from the brackets that hold the fuel injection pump housing to the cylinder block.5. Remove four bolts (4). 6. Fasten a hoist to fuel injection pump housing and governor (6). Slide the fuel injection pump housing to the rear and remove it. The weight of the fuel injection pump housing is 110 lb. (49.5 kg). 7. Remove two O-ring seals (8) and O-ring seal (7).Install Fuel Injection Pump Housing And Governor
Make sure the outer surface of the fuel system and the surfaces that come in contact with it are clean.
1. Inspect the O-ring seals for wear or damage. Make a replacement if necessary. 2. Install O-ring seals (1) and (2) on the fuel injection pump housing. 3. Fasten a hoist to fuel injection pump housing and governor (3) and lower it into position. Install the four bolts that hold the fuel system to the cylinder block. 4. Install three bolts (5).5. Connect governor linkage (4) to the governor. 6. Connect line (6) to the air-fuel ratio control.7. Connect two lines (7) to the transfer pump.8. Connect two lines (8) to the fuel injection pump housing.end by:a) install fuel injection linesb) install automatic timing advance
