Yes, all part numbers listed on these sites are updated from time to time, and the same diagrams can also be found on Yamaha's website. Typically the diagrams on the OE's website are the most trustworthy. The new parts work the same as the old, but the part numbers will change due to revisions in the overall part design or change in material type, or maybe even a supplier change. From personal experience I have found that the earlier part numbers generally are of better build quality, due to the fact that as time progresses, suppliers must find cheaper and less costly ways to manufacture the more recent parts. This is not saying that new number = bad part.
