General Safety Instructions • Wear eyeshields when using compressed air. • Do not allow solvents to get on skin or clothing. • Compressed air for cleaning purpose will not exceed 30 psi (207 kPa). This task covers: a. Disassembly c. Inspection b. Cleaning d. Assembly INITIAL SETUP: NOTE The fuel injection pump repair procedures for pre-1990, 1990 and above 6.2L and 6.5L engines are basically the same. Difference in procedures are noted. Refer to para. 1-10 to determine engine model before ordering replacement parts. Before disassembly, fuel injection pump should be tested (para. 2-33.c, 2-34.c, or 2-35.c) on calibration stand to determine type of pump malfunction. Do not disassemble fuel injection pump if no malfunction is found after preliminary test. Work area should be clean, well-ventilated, and free from blowing dirt and dust.
