Set of two crankshaft bearings for 50 4T engines (manufacturer TATA). The bearings hold the crankshaft in the crankcase and let it rotate without binding.
Replace them if you hear a hum, notice increased vibration or play in the crankshaft. The job requires splitting the crankcase, so it is convenient to combine bearing replacement with an engine repair and replacement of the oil seals. When buying, compare the markings on the old bearing: they define the size unambiguously.
