555E Injection pump leak

Steve12000 · 2023-12-02 06:10

Hi, I have a 1997 New Holland 555E back hoe. VERY NEW to this stuff. I have a slow drip on a circular pieceon what I believe is where the throttle connects to the injection pump. Is this a gasket behind/inside the ring that holds this brass piece on? Thank you. --Steve

    Not sure if these are the correct illustrations for your pump but looks like it could just be a 0-ring. They give the size and part number in the manual. Maybe thepumpguysc will come along and confirm?

    Yes.. it’s an oring.. Remove snap ring, grab knob w pliers and wiggle it out.. change oring, lube and tap in w a hammer.. reinstall snap ring. Done..
