Boston Gear 300 Series Model 711 Reducer Ratiomotor FWC318-2000-?1 We are listing this as a used item. However, it may have been a new spare or refurbished unit at some point and not put back into service, because there are no bolt marks on the mounting tabs on the base. It has a lot of scuffs and shelf wear. The last two numbers of the catalog number are faded and difficult to read and may have been .11 or 11, but we are not sure. It is also marked, "Input 1750RPM, Input HP .167, Output Torque 590 LB In.". The motor is labeled, "EC 0650-00-075, Electro-Craft". We are not able to find any marking about the ratio of this unit. The keyed shaft has some surface rust. The shaft measures about 1 7/8" long X 7/8" diameter. It has a 5 pin circular male connector as shown in the pictures. We are not able to test it. It only comes with what is shown in the pictures. WB S4-4 d 8419198 rl fdk 80821238
