Re: Why not smaller chain?
Orbit, I think that you have a valid point about the left drive chain,although a #41 chain is too wide between the plates (1/4")
A #42 chain has the correct dimensions; 1/2" between pins and 3/16"
width between the plates. That is the proper size to fit the front and
rear sprockets. The weight of the chain is really of little concern, but
the quality of the chain will make a difference.When a chain stretches,
it's stretching the side plates of the chain, and only on approximately
1/2 of the chains total length. This causes the chain rollers to try to
climb up the sprocket teeth instead of setting into the sprocket grooves. Besides creating noise, it wears the sprocket teeth very fast!
