How to Replace the Injector on a 7 3 Diesel

Ford produced an eight-cylinder, 7.3-liter diesel engine from 1995 to 2002. This engine was frequently turbocharged and typically appeared in heavier trucks, beginning with the 3/4-ton pickups. Each cylinder has its own fuel injector, which delivers fuel to that cylinder at high pressure. You can remove each fuel injector on a Ford 7.3-liter diesel engine independently of the other injectors without removing the fuel rail from the engine.

Instructions

    1

    Disconnect the valve cover with a socket wrench. Unplug the electrical connector from the fuel injector and disconnect the drain plugs on the oil rail. Disconnect the oil deflector by removing its mounting screw with a socket wrench. Disconnect the outboard retaining bolt for the fuel injector.

    2

    Place the fulcrum of the Injector Remover No. T94T-9000-AH1 above the cylinder head and below the fuel injectors hold-down plate. Attach the injector remover to the cylinder head with the remover screw for the injector remover. Tighten the screw until the fuel injector comes out of the injector bore.

    3

    Discard the copper washer on the fuel injector. Use the Rotunda Injector Sleeve Brush 104-00934-A to remove any sealant residue from the injector bore and clean the injector bore with a shop towel. Coat the new fuel injector in engine oil and install a new copper washer to the injector. Place the fuel injector into its bore.

    4

    Position the end of the Injector Replacer No. T94T-9000-AH2 below the fuel injector and above the hold-down plate. Align the threaded hole in the cylinder head with the hole on the injector replacer tool. Install the bolt for the injector replacer tool to fasten the tool to the cylinder head. Tighten the bolt to fully seat the fuel injector into the injector bore on the cylinder.

    5

    Install the oil deflector, fuel rail drain plug and oil rail drain plug with a torque wrench. Torque the oil deflector mounting bolt to 108 foot-pounds. Torque the drain plug for the fuel rail to 96 foot-pounds and torque the drain plug for the fuel rail to 53 foot-pounds. Attach the electrical connector for the fuel injector and replace the valve cover with a socket wrench.
