摘要：
An anti-rotation oil filter system to prevent inadvertent release of the oil filter from a lubrication system is provided. The system includes a ratchet gear attached to one of either the oil filter or the engine's oil filter attachment base. In both embodiments, a spring-loaded ratchet release pawl is provided to engage the ratchet and to thereby hold the filter in place against the attachment base until such time as the filter needs to be changed. Where the ratchet gear is fitted to the filter, a ratchet release pawl is associated with the engine's oil filter attachment base. The teeth of the ratchet ring gear extend outwardly from the filter. Alternatively, where the ratchet gear is fitted to the engine's filter attachment base, a ratchet release pawl is associated with the filter. Regardless of the embodiment, the ratchet gear and pawl arrangement restricts filter rotation to maintain clamp load.
