Mechanical Pencil Spring Replacement

はじめに

If your mechanical pencil no longer produces lead - either no lead is produced from pressing the dispenser, or the dispenser cannot be compressed - this guide can help you restore function. An Xtra Strong Mechanical Pencil is used in this guide, although the process is similar for other brands. This fix targets the replacement of broken or jammed springs, which anyone of any technical skill level can accomplish. Your mechanical pencil will need to be disassembled, the old spring removed and replaced, and then reassembled. No special considerations or tools are required.
