Camshaft bearing set for 50cc 4T scooters, models 6002 and 16002. They support the camshaft in the cylinder head and let it rotate smoothly.
Replace them if there is a metallic knock in the head, noise at idle, or play in the camshaft. Replace both bearings, and when disassembling, check the condition of the shaft journals. Press the new bearing in by the outer ring, without striking the cage or the inner ring.
