Quality of the fuel
Quality of the filtration of the fuelThe wear of the unit injectors can result in elevated levels of exhaust emissions and/or poor engine performance. The misfire of a single cylinder is not typically attributed to normal wear. This condition can be repaired by replacing the faulty unit injector.The following list of circumstances indicates that the unit injectors should be inspected more frequently:
Use of fuels that are not recommended in this Operation and Maintenance Manual, "Fluid Recommendations"
Extreme ambient temperatures that reduce the ability of the fuel to provide lubrication
Frequent plugging of the fuel filters
Insufficient maintenance of the fuel tank or the fuel storage tank that can allow excessive water, sediment, and other contaminants
Insufficient maintenance of the fuel filtersOil Suction Screen
Clean the oil suction screen after the oil has been drained.Note: Approximately 1 L (1 qt) of oil will remain in the housing after the sump has been drained. This oil will pour out of the housing when cover (1) is removed. Prepare to catch the oil in a pan. Clean up any spilled oil with absorbent towels or pillows. DO NOT use absorbent particles to clean up the oil.
Remove the screen assembly according to the instructions in the Disassembly and Assembly Manual, "Engine Oil Pan - Disassemble". Discard the used O-ring seals.
Wash the screen assembly in clean nonflammable solvent. Allow the screen assembly to dry before installation.
