Excessive movement or "clunking" noises are usually caused by a worn 166-1901 bushing or a damaged bucket pin. If the internal diameter exceeds the wear limit from the original 160mm, it puts stress on the excavator arm. We recommend immediate replacement with our 1661901 parts to prevent costly damage to the main structure.
OEM-standard tri-metal structure ensures superior load-bearing capacity. Our parts are trusted by repair shops and equipment fleets worldwide because they match the exact metallurgy of original components at a more competitive price point.
