Maybe you run a store where you sell Widget and Deluxe Widget. The only difference is Deluxe Widget has a higher max RPM, but the operating instructions for Widget and Deluxe Widget are identical.
As a consumer, if I came to the website looking for instructions on how to use my [Deluxe] Widget, I would reasonably expect to find the same operating guide on both product pages.
Maybe you should collapse these admittedly identical items into variations of the same product, which will reduce the useless duplicated clutter I'd experience when searching your catalogue.
