I have a Grizzly g 7948 drill press. There is a nylon nut that holds the pulley on. Does any one know what that should be torqued at? I read one article and fellow said Grizzly didn't know. I can't believe that you cant get any info from Grizzly. They say the G7948 has been discontinued and no parts available. I can't believe the would not make that part available. Don't know why they ever uses a nylon nut to even start with.
