I need information concerning the difference between the v belt outdrive pulley on a 9in. tool room cabinet model and the outdrive v belt pulley on a 9in. horizontal lathe. The part number is the same on the spindle cone pulley for both but the part numbers for the outdrive pulley are the same except the tool room cabinet has a 1 on the end and the horizontal has a 2 on the end. I have a set of v belt pulleys from a horizontal but I really need to know if there is any difference before I start the tear down to install them. Any help is appreciated.
