Needle cage bearing d10 — a needle bearing in a cage (retainer). Used in assemblies with a piston pin; the number in the name is the diameter, 10 mm.
Replace it if the pin has play in the small end of the connecting rod, if the engine knocks, or if the needles are worn. Before ordering, compare the diameter with the size of your pin. When buying, compare the markings on the old bearing: they define the size unambiguously.
