I know nothing about these.. I bought it a set of belts. Tried it out – Runs great. Everything that is here works and works well. The motor runs well – and the power feed assembly works well. There is a piece cracked off of the largest pulley wheel that drives the lathe shaft – It still runs fine and the missing piece does not seem to interfere with the belt. That’s about all I know!
