Fuel leaked or spilled onto hot surfaces or electrical components can cause a fire. Clean up fuel spills immediately.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
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.
The 1U-5470 Engine Pressure Group or the 198-4240 Digital Pressure Indicator can be used in order to check the engine's fuel pressures.Refer to Special Instruction, SEHS8907, "Using the 1U-5470 Engine Pressure Group" for the instructions that are needed to use the 1U-5470 Engine Pressure Group. Refer to Operation Manual, NEHS0818, "Using the 198-4240 Digital Pressure Indicator" for the instructions that are needed to use the 198-4240 Digital Pressure Indicator.
Illustration 1 g01140172The fuel pressure should be in the following range when the engine is under normal operating conditions and the engine is under load:
400 to 525 kPa (58 to 76 psi)At low idle, the fuel pressure at the fuel filter's inlet should be at the following amount:
400 to 435 kPa (58 to 64 psi)The fuel pressure to the passage for fuel supply should be the same amount, if you subtract the change in pressure (delta P) across the filter. With a new filter, the pressure drop across the fuel filter typically registers the following amount:
35 kPa (5 psi)As abrasive particles collect in the fuel filter, the pressure differential across the filter will increase. When a filter becomes plugged, fuel supply pressure may drop as low as 69 kPa (10 psi) before a significant power loss is detected by the operator. Low fuel pressure will cause cavitation and internal damage to the unit injectors. The pressure differential across the fuel filter should not exceed 69 kPa (10 psi).To check the filtered fuel pressure, follow this procedure:
Remove the plug (1) from the fuel filter base.
Install the connector, the seal, and the engine pressure test group into port (1) in the fuel filter base. Refer to Special Instruction, SEHS8907, "Using the 1U-5470 Engine Pressure Group".
