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 rack actuator package 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 governor 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). 6. The weight of the fuel injection pump housing and rack actuator package is approximately 57 Kg (125 lb.). Attach a hoist to the full injection pump housing and remove bolts (9). 7. Remove two nuts (one 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).3. Connect wiring harness to bracket (7). 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 rack actuator package and aftercooler housing. For timing of the fuel injection pump, see Install Timing Advance Unit.End By:a. install timing advance unit.
