Oil drain bolt for Active mopeds. The bolt closes the drain hole in the crankcase. The used oil is drained through it during an oil change.
Replace it if the thread is stripped, the corners are rounded, or it leaks. After draining the oil, tighten the bolt carefully with a new sealing washer. Overtightening can strip the thread in the aluminum crankcase. When replacing it, inspect the neighboring parts of the assembly: they often wear out at the same time.
Country of origin: China.
