Atlas 10, back gear lever climbing

[great white]

I’ve been using my back gears a lot lately on my TH42.

It was working great until yesterday. The back gear lever has started climbing out if engagement.

Now, my “bull gear” stack came a little loose a few days ago. Grub screw worked itself loose. It might have been from when I went through the headstock a few weeks ago, cleaning and lubricating. I just pushed the bull gear back against the stack and retightened the grub screw.

Do I have an alignment issue now? Could that be why the back gears now climb off the bull gear under load?

I’m digging through the molo right now, but still haven’t found anything...

Nevermind. I figured it out.

Somehow, my back gears had managed to shift towards the tailstock enough to make them climb the bull gear under load.

Loosened a few grib screws, tapped the back gear shaft with a soft faced hammer, re-tighten grubs and it cuts like a champ again.
