Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat products. Dispose of all fluids according to local regulations and mandates. |

Do not let the tops of fuel nozzles turn when the fuel line nuts are loosened or tightened. The nozzles will be damaged if the top of the nozzle turns in the body. The engine will be damaged if a defective fuel injection nozzle is used because the shape of fuel (spray pattern) that comes out of the nozzles will not be correct. |
Note: The removal procedure is similar for the two cylinder, the three cylinder and the four cylinder engines. The illustrations show the C2.2/3024C and C2.2/3024CT engines.
- Disconnect the union nuts (1) for the fuel injection lines (2) from the fuel injection nozzles.
- Disconnect the union nuts (1) for the fuel injection lines (2) from the fuel injection pump.
- Remove the fuel injection lines (2) from the engine as a unit.
Note: Place identification marks on all tube assemblies for installation. Plug all tube assemblies in order to prevent contamination.
- Install suitable plastic plugs to the outlet connections of the fuel injection pump.
- The C1.5/3013C, C2.2/3024C and C2.2/3024CT engines have a rigid fuel return line.
For engines with a rigid fuel return line, remove the banjo bolt (4) from the fuel return line (3). Remove the washers (8) from the fuel return line (3). Discard the washers.
The C0.5, C0.7, C1.1/3011C and C1.6 engines have a flexible fuel return hose.
For engines with a flexible fuel return hose, disconnect the union nut from the banjo piece.
