Where's this supposed to be?

Had the trailer in for slide out motor exchange (installed one underpowered at factory) and found this housing loose. Where's it supposed to tightened? All the way to the left? Right? Middle? What's it protecting?

I would say that it should be slid to the left. The purpose to to protect and cover the hydraulic cylinder slide to keep dust/dirt/grime from getting into the cylinder itself, via the shiny slide/ram part of it.

Does the slide move in/out correctly?
Did the slide seals make good contact when in & out?
If so I'd leave things as they are til you find out for from someone with more knowledgeable than me or any other non rv tech on here.
There are a couple of those rv techs with the knowledge on here, I'd wait til they chime in before you start running wrenches.
From what I see that may be the adjustment for the inward/outward slide movement, but just a guess.

The housing doesn't slide. Housing and locking nut are threaded and run along the threaded shaft. Everything works as it should and seems to be within specs. That's where I set it when I found that the cover and nut were loose. I'm just wondering if it's for when the slide's retracted and fits up against the frame or other flat surface to make a somewhat weather/roadproof cover.

That's the "stop can". It is located on the powered ram of your slide mechanism. The purpose of the stop can is to "stop your slide from moving in" when that can reaches the frame. It prevents the slide from "crushing the trailer sidewall" by preventing it from moving in further than it should. It is adjusted to the proper distance on the slide ram, and then when you retract the slide, that can stops further "inward movement" and the gear mechanism starts to ratchet and the slide stops moving inward.

Here's a pretty good video of what it does and how it works:

You want to be extremely careful if you start "just moving the stop can until it looks like where it used to be" or "tightening it by screwing down the stop nut (it may need to be screwed out to the stop nut instead)....

That stop can is the only thing that prevents your 8' wide trailer from becoming a 7' wide trailer if you're not quick enough on the slide button when bringing in the slide......

I'd guess than when the dealership replaced the motor and realigned the ram, they didn't "finish the job completely" and left (overlooked) adjusting and tightening the stop can....

John is spot on as usual.

Almost…see John’s reply. I have seen some pretty bent up ones.

Thanks for the replies. Now that I know what it's for, I can set it appropriately.
