Went to set the backlash comp on a new to me Tree Journeyman 325 and was not happy with the numbers already set into the controller...time for new balls.
The maintenance manual (only one I got witht the machine) describes the X and Z ball screw removal, but skips the Y axis (an ominous indicator).
Just for anyone else wanting to travel the path...here is what I found.
Everything related to Y axis:
Remove the drive belt cover, remove the servo motor and belt.
Remove setscrew at front of metal way covers and slide covers out front of machine (ref picture). My machine doesn't have soft way covers yet...so you will have to deal with those as necessary. Note that the picture shown already has the ball nut unfastened and is hanging...at this point, just screw the screw out the front of the machine and you will have decent acess to the ballnut fasteners and oiler nut through the top of the knee opening. Gifted with long arms, I could touch the end of the screw while turning the screw out to ensure I stopped flush with the ballnut and not out of it just yet.
