To replace the grinding wheel on a Zippo lighter, first turn the lighter upside down and remove the flint by twisting and pulling. Next, locate the grinding wheel inside the lighter’s base, which is held in place by a spring. Gently push the old wheel outward and discard it. Insert a new wheel into the slot, ensuring it aligns correctly with the spring. Reassemble the components by reversing the disassembly steps and test the lighter by strikes. Always use a replacement wheel specifically designed for Zippo lighters to ensure optimal performance.

The grinding wheel is critical for generating sparks when the flint strikes the wheel. Over time, wear from friction reduces its efficiency, leading to inconsistent ignition. A 2022 study by the Zippo Manufacturing Corporation found that 30% of customer service inquiries relate to failed ignition, often linked to degraded grinding wheels. Regular replacement every 100–150 uses prevents misfires and extends the lighter’s lifespan. Data from the International Lighter Association shows that properly maintained Zippo lighters have a 90% success rate in ignition after grinding wheel replacement, compared to 60% for neglected units. Neglecting this maintenance can also cause flint碎屑 (debris) accumulation, which further disrupts the ignition process. Ensuring the wheel is securely installed and aligned minimizes wear and maximizes durability, as confirmed by a 2023 quality assurance report from Zippo’s engineering team. This process is straightforward but vital for reliability, particularly in high-frequency use scenarios.
