Wondering the interchangability of #41 chain and sprockets with #40. In other words will a #41 Chain work on a #40 sprocket? I ask this as my equipment has #41 chain, but I see you only have #40 on these sprockets

A: #41 chain is narrower between the plates than #40, though they have the same pitch length. You can use #40 chain on #41 sprockets, but cannot use #41 chain on #40 sprockets.

Is this for 41 chain

A: No. This is for 40 pitch, which has the same pin to pin measurement, but 41 is a narrower chain between the link plates. A 41 sprocket will work with 40 chain, but 40 sprockets will not work with 41 chain.
