Looking for some info on disassembling a knee mill spindle.
I have a 10 year old Grizzly knee mill that has something broken in the spindle assembly. It does not feel like a bearing as the mill still works and sounds fine. The problem is when I do a "Z" move up or down something in the assembly seems to slip, grab and bind up. You can on occasion move the spindle up and down rapidly and everything slips loose and back into place and works for a short time.
I would like to tear into it but can seem to find any instructions anywhere. I really dont want to start ripping it a part as possibly doing way more than whats necessary.
Can anyone point me in a direction to get me started? Thanks.
