Default Y axis "rattle"

After greasing the Y rails, I "jogged" the machine around and heard some noise from the one Y axis. The noise only seemed to occur when moving in one direction. After taking off the black motor and gear housing/protection, it looks like the gear (transmission?) is not sitting as it should be:


I loosened the 4 screws for the motor and am able to pull the gear/transmission and hold it with my hand where I think it should be:


The hand holding the gear is where it should be, correct? (or at least closer to where it should be)

Before taking any more actions, I wanted to take the safe route and ask here first on what should be done.

It looks like there may have been some abuse here:


I am the second owner of this machine and would appreciate any help on how to adjust things appropriately and get this machine back to its optimal operation.

Took the gear assembly off. Loosened the set screws on transmission and gear, pushed them both in closer to each other on the shaft, re-tightened set screws and noise is now gone. Hopefully that solved the issue until next maintenance cycle.

The gear looked like it could be replaced. Guess I should figure out how to take it off eventually.

Interestingly, today was "Stinger maintenance day" in my shop and just for grins, I pulled off the covers over my Y axis so I could see more directly what you had been working on. It wasn't just on a whim as I had a stall and some wonky cuts recently so taking a look, particularly on the right side made sense. The left side was perfect, but the right...way loose on the belt. I'm thinking it may have been that way all along as I had the loose belt thing on the X axis motor early on after delivery, or it could have gotten jared when I had the stall a few weeks ago. (which was totally my fault for not measuring properly when surfacing a slab)

So I thank you for the idea to check them!!

The other y axis motor assembly on my machine was tight without issue as well.

Glad you were able to get your belt tightened up!

Edit:
Just realized you are a fellow commonwealther over in Bucks. Hello from Montgomery County. Hope retirement is treating you well
