Crankshaft bearings for Let's, sizes 6204 and 6000 (manufacturer TATA, country of origin: China). They secure the crankshaft in the crankcase and let it rotate while the engine runs.
Replace them if the engine hums and vibrates. The job requires splitting the crankcase; during the repair, replace both bearings together with the oil seals. Press the new bearing in by the outer ring, without striking the cage or the inner ring.
