This check assembly is a Single Check Assembly for 805 Series, and 2nd Check Assembly for 825 Series. The check covers were also redesigned and in turn the cover O-rings are different. All rubber repair kits include both old and new style cover O-rings. Check disc rubbers remained the same through all the years of changes.
