You shouldn't have to adjust the backlash on a machine with low hours like yours.
A lot of machines (Makino and Mori at least) have direct drive B-Axis. Zero backlash
I don't think there are. Personally, I'd have to think long and hard before I bought a used machine with a full 4th. That seems like a ticking time bomb.
Weird.. I couldnt see life without the full 4th for what we do... We have 5 mazaks with full 4th... I have seen very few issues with the B on these machines... One I seem to recall having an issue, but it was due to negligent "maintenance"
If you doo much heavy machining in steel - big drills especially - clear out at the ends of your X travel - you can start wishing that you had a 1* indexing.

Good luck and keep us posted with thisWell, the tech was here again today. He adjusted the backlash, but the servo load was still high. He pulled out the worm and the bearings (tapered roller) were pretty rough looking. After taking out the worm, and unclamping the brake, the table didn't want to move by hand. He's thinking the brake is dragging for some reason. That's it for today, tomorrow more disassembly.
