Abstract: The external oil pan magnet (10) is placed on the external surface of the oil pan (2) where it attracts and captures metallic particles suspended in a motor's oil supply. In a first embodiment, the external oil pan magnet (10) is comprised of magnet (12) coupled to a channeled shield (14). The shield (14) leaves at least one surface of the magnet exposed and amplifies the magnetic force of the magnet. The exposed surface magnetically attaches to the external surface of the oil pan (2). After the oil is drained during normal maintenance, the operator slides the magnet assembly across the bottom of the pan and over the oil pan plug hole. Metallic debris is evacuated through the oil pan plug hole. The plug is replaced and the oil supply replenished. In a second embodiment, the magnet assembly is configured to encircle the oil pan plug. The magnet temporarily magnetizes the plug which attracts metallic debris from the oil.

Abstract translation: 外部油盘磁铁（10）放置在油盘（2）的外表面上，吸引并捕获悬挂在电动机油源中的金属颗粒。 在第一实施例中，外部油盘磁铁（10）由耦合到通道屏蔽（14）的磁体（12）组成。 屏蔽层（14）离开磁体的至少一个表面并放大磁体的磁力。 暴露表面磁性地附着在油盘（2）的外表面上。 在正常维护期间排出油后，操作人员将磁体组件滑过锅底部并在油盘塞孔上方。 金属碎屑通过油盘塞孔抽真空。 插头被更换，补油。 在第二实施例中，磁体组件构造成环绕油盘塞。 磁铁暂时使塞子磁化，从油中吸收金属碎屑。
