Fitment Notes

Always confirm final fitment by checking the Komatsu part number, machine model, serial range, dimensions, and arrangement before ordering. The same part number can appear across multiple models or serial ranges depending on the machine configuration.

For best results, inspect the related bushings, bores, seals, and retainers during installation. Pins and bushings are often replaced together when wear is uneven, since installing a new pin into worn bushings can shorten service life and create excess movement in the joint.
