The rear oil seal for the crankshaft is a fundamental component that prevents the leakage of lubricating oil from the engine’s crankcase. With a thickness of approximately 12.7 mm and an inner diameter of 132.46 mm, it fits precisely into the crankshaft housing, providing a reliable barrier against oil seepage. Its outer diameter of 165.46 mm ensures a secure fit within the seal housing, maintaining tightness even under high engine speeds and thermal cycles. Proper functioning of this seal is essential for maintaining proper lubrication, reducing engine wear, and preventing oil contamination of other engine compartments. Regular inspection and replacement are necessary to sustain engine efficiency.
