If you have a door hinge with non-removable pins and need to remove it for maintenance or other reasons, you can follow these steps:
Check for set screws: Some non-removable hinge pins may have set screws that hold the pin in place. Look closely at the hinge barrel and see if there are any small set screws. If there are, use a suitable screwdriver or Allen key to loosen and remove them.
Tap out the pin from the bottom: Place a nail or a sturdy pin punch (a metal rod with a pointed end) at the bottom of the hinge pin. Tap the pin punch gently with a hammer to create a slight gap between the hinge knuckle and the pin.
Leverage the pin out: Insert a flat-head screwdriver into the gap you created in the previous step. Carefully apply upward pressure to lift the pin out of the hinge. Be gentle to avoid damaging the door or the frame.
Use a nail set or punch: If you find it challenging to create a gap between the hinge knuckle and the pin, you can use a nail set or another slender, strong tool to tap the pin upward. Place the nail set or punch on the top of the pin and tap it with a hammer to drive the pin up and out of the hinge.
Alternate method (if applicable): Some non-removable hinge pins are designed with a groove or notch near the bottom of the pin. In such cases, you can use a flat-head screwdriver or chisel to push the pin sideways slightly and align the groove with the edge of the hinge knuckle. Then, use a hammer and nail punch to tap the pin out sideways.
Be prepared for resistance: Non-removable pins can be more challenging to remove than standard removable ones. It may take some effort and patience to remove the pin successfully.
Replace the pin: Once the pin is removed, you can decide whether to replace it with a new pin or keep the hinge without the pin. If you choose not to reinstall the pin, make sure the hinge is securely attached to the door and frame.
Remember, if you are unsure about removing a door hinge pin or encounter any difficulties during the process, it's best to seek assistance from a professional carpenter or handyman. They will have the necessary expertise and tools to handle the task safely and effectively.
