DAYTON 4Z290B Speed Reducer Gearbox. Ratio 10:1. 3/4 HP. Output Torque 230 in. lbs. INPUT speed 1725 RPM. Output speed 173 RPM. This gearbox was used with a pulley to help grind chunks of wax using a meat grinder. It had minimal use and hasn't been used for the last 15 years. I have sold 5 others already and have 2 left. There is a pulley wheel attached . Overall , very good + pre-owned condition. Thanks.
