Information:

1. Disconnect fuel line (1) from the fuel transfer pump. Disconnect fuel line (2) from the fuel injection pump housing. Remove line (3) from the transducer module and aftercooler housing.2. Disconnect fuel injection lines (4) from the fuel injection pump housing.
Do not disconnect the air line from the air compressor until the air pressure is zero.
3. Loosen the bleed valves, and release the air pressure in the air tank.4. Remove air line (5). Remove coolant line (6). 5. Disconnect wiring harness from bracket (7). Disconnect wires at connectors (8).
Typical Example6. The weight of the fuel injection pump housing and rack actuator package is approximately 57Kg (125 lb.). Attach a hoist to the fuel injection pump housing and remove bolts (9).
Typical Example7. Remove two nuts (on shown) and two bolts (10). Remove bolt (11). Remove the fuel injection pump housing and rack actuator package (12).
Typical Example8. Remove O-ring seals (13) from the fuel injection pump housing.Install Fuel Injection Pump Housing And Rack Actuator Package
1. Attach a hoist to the fuel injection pump housing and rack actuator package (12). Be sure that the three O-ring seals are in position in the fuel injection pump housing. Install the fuel injection pump housing and rack actuator package on the timing gear housing. 2. Connect the wires at connectors (8).
Transducer Module3. Connect P5 to J5 connector, J11 to P11 connector, and P10 to J10 connector. 4. Install air line (5) and coolant line (6).5. Connect fuel injection lines (4) to the fuel injection pump housing. Tighten the fuel injection line nut to a torque of 40 7 N*m (30 5 lb.ft.) with tool (A).6. Connect the fuel line (1) to the fuel transfer pump. Connect fuel line (2) to the fuel injection pump housing. Install line (3) to the transducer module and aftercooler housing.
