Crankcase, Oil Pump for 50cc ATVs & Dirtbikes

Crankcases and oil pumps form the foundation of the lubrication and lower-end structure in 50cc Honda-type ATVs and dirt bikes. The crankcase supports internal engine components, while the oil pump circulates oil to keep everything properly lubricated. When these parts wear out, crack, or fail, riders may experience leaks, overheating, or engine damage. Replacing damaged crankcases or worn oil pumps helps restore dependable engine performance on youth models from brands like TaoTao, Coolster, and SSR.
