Hope someone can help, I have an old Enco 12 36 lathe model 92030 DOM 1983 and it looks as if someone has changed the motor and has put a single pulley on it. It came with a 2 step and I have no clue what size to shop for. I have checked with Enco and they cannot help. Everything else on the lathe works great so I would like to put the correct pulley on it. Does anyone have one that they can measure or a manual that will help or better yet some experienced knowledge. The best I can find is a part number for a similar lathe pulley , part # 3G-17 but no clue what size the pulleys are. Any help will be greatly appreciated.
