We have a Hawk 200 lathe that had the spindle drive motor pulled and checked before we purchased it. Evidently the motor shop lost or broke the drive pulley and replaced it with a 44 tooth pulley instead of the original 42 tooth. This is a 1:1 machine and obviously when trying to do any operation that requires spindle synchronization, tapping, threading, etc it cannot. I see a parameter in the service screen that asks for drive ratio, but it will not accept new entries. Are we stuck with purchasing the correct pulley or ???
