Set of two crankshaft bearings for 150cc 4T scooters, part no. 0032 (manufacturer TATA). The bearings hold the crankshaft in the crankcase and let it rotate.
Replace them if the engine hums, vibrates, or the shaft has play. The job involves splitting the crankcase — combine it with replacing the oil seals and other worn parts. When buying, compare the markings on the old bearing: they define the size unambiguously.
