This XCMG OEM Bushing (P/N 253100720, 800KII.8-3) is precision-machined from high-density bronze or steel-backed composite material, serving as a self-lubricating sacrificial wear layer that protects pivot pins and shafts from direct metal-to-metal abrasion in loader linkage arms, cylinder mounts, and articulation joints. Built to withstand heavy radial loads, side thrust, and constant oscillation in harsh conditions—from quarry loading to port bulk handling—it is the essential companion part to replace together with pins during scheduled 2000h/4000h linkage overhaul, eliminating joint play, restoring steering accuracy, and extending the service life of the entire front-end assembly.
