HARNESS AS-WIRING 2577447 - Caterpillar

Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility.
To improve the reliability and performance of its products, Cat Reman has replaced the entire product line of HI315B Injectors with a version that includes a pre-screen that will capture a portion of the debris trapped in the fuel system during service. The pre-screen will not change the fit, form, or function of the injectors. If a Reman injector order has been filled with new injectors, the new injectors will not have the screen. Injectors both with and without the pre-screen can be used interchangeably.
