NOTES: - To install the new fuel lines reference Images 1.5.1 through 1.5.5. For more detailed images reference the fuel lines groups in SIS WEB. When installing fuel lines that incorporate a hose assembly, a back-up wrench must be used to prevent any hose twisting and undo stress to the fuel lines. - When installing these new fuel lines the wiring harness will need to be re-routed in some areas to prevent interference. - Fuel line installation best practices should be followed. All fuel line connections should first be installed hand tight, all clips and clamps should then be installed, and finally all fuel connections should be tightened to the correct torque value. - All of the fuel lines metal surfaces and mounting hardware must be painted to match the engine prior to installation to prevent rusting. Ensure that all ends of the fuel lines are capped during the handling and paint process to prevent fuel system contamination. |

If you encounter a front housing dissimilar to the images in this service letter please contact your Marine Customer Service Representative or DSN for guidance. For torque specifications reference media number SENR3130. Note: It is critical that the correct rework group is identified by engine serial number and that the rework is followed step by step to ensure that incorrect assembly does not occur. Caution: Ensure the engine is shut down and steps have been taken to prevent any attempt to start the engine while fuel hoses are being updated. 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, "Caterpillar Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Caterpillar products. Dispose of all fluids according to local regulations and mandates. Keep all parts clean from contaminants. Contaminants may cause rapid wear and shortened component life. |
