Built for demanding jobsite conditions, this replacement bucket pin is made for strength, durability, and long service life when installed correctly and maintained with proper lubrication. It is intended to meet the fit and performance requirements needed for high-wear Komatsu pivot joints.

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