New components need to be installed to improve the front linkage reliability on certain 992G Wheel Loaders. The 'E' and 'C' joints of the linkage (both ends of the bucket link) have been redesigned to grease pins to improve operation of the linkage. The 'E' and 'F' joints (both ends of the boom links) have improved pin flags to reduce wear.
