The Komatsu 13Y-50-12130 pin is a replacement wear component for compatible Komatsu heavy equipment assemblies. It helps maintain alignment and provides a durable connection between moving or pivoting machine components.
Pins should be inspected for scoring, corrosion, bending, uneven wear, and loss of diameter. Continued operation with a worn pin can increase joint clearance, damage bushings, and eventually contribute to wear in the surrounding mounting bores. Replacing the pin and inspecting the related bushings together can help extend the service life of the complete joint.
Always verify the part number using the correct Komatsu parts book for your machine model and serial-number range.
Common machine models include: D355A, D61EX, D61EX-23M0, D61EXI, D61PX, D61PXI.
