Following the recommendations of the Operation and Maintenance Manual will allow the injectors to achieve a full service life. The recommended replacement of the injectors is at the top end overhaul. Follow the recommendations of the OMM in order to maintain the engine's full performance capability.

Use clean fuel and the proper fuel filter in order to increase the life of fuel injectors. Refer to the following publications:

• Booklet, SENR9620-02, "Improving Fuel System Durability" Available through Media Logistics. Package of ten

• Operation and Maintenance Manual, SEBU6250-14, "Caterpillar Machine Fluids Recommendations"

• Applied Failure Analysis, SEBD0717-02, "DIESEL FUELS and your engine"

Note: Poor fuel quality is the major factor in reducing the service life of injectors. Use fuel that meets the recommendations of the engine's OMM.
