Exhaust nuts often seize due to corrosion forming on the exhaust studs that hold the exhaust clamp in place. The corrosion that forms is rust. The heat generated by the exhaust coupled from humidity and water causes the rust to form thick on the threaded section of the exhaust studs. To remove difficult exhaust nuts, you often have to use heat from a torch. If you cannot use a torch to release the nuts due to the proximity of the nuts to a fuel line, there is another option.

Instructions

  1. 1

    Spray penetrating oil onto the difficult exhaust stud and allow the penetrating oil to soak into the exhaust nut for at least three-hours before you proceed to the next step.

  2. 2

    Select a socket from the socket set that fits onto the difficult exhaust nut.

  3. 3

    Place the socket onto the 1/2-inch drive ratchet and slide the nut onto the difficult exhaust nut.

  4. 4

    Set the 1/2-inch drive ratchet to loosen and turn the handle of the ratchet counter-clockwise to attempt to loosen the exhaust nut. If the nut does not loosen, proceed to step four.

  5. 5

    Insert the handle of the 1/2-inch drive ratchet into the 24-inch long piece of 5/8-inch I.D. pipe.

  6. 6

    Continue to push the pipe attached to the ratchet counter-clockwise to attempt to release the difficult exhaust nut.

  7. 7

    Reverse the direction and attempt to tighten the exhaust nut. If the nut does not move, slide the pipe slightly down the ratchet handle to give you more leverage and push as hard as you can. The seized nut will snap the threaded section of the exhaust stud.

  8. 8

    Repeat the process to snap other difficult exhaust nuts that will not release and turn off the threaded exhaust studs.
