    Series 1 Boss 3 Head Rebuild (2J Head) - Stuck Here.

    Hi Folks,

    I'm about to order a top end rebuild kit. Do these kits cover the CNC version mill with the nod and tilt head? I noticed that my top end quill assembly is longer than the typical manual machine. I'm also curious if the kits usually come with the bearings below the bull gear, which is where I am now.

    I do not know which bolts [or nuts] to remove here? I've read a few counts that one set is NOT to be loosened as that is a factory alignment. Does anyone know which set to remove here, upper bolts or lower nuts?

    Thanks for any assistance.
