Iíll keep you posted on what I find.
This is why you donít leave your slides open all the time. If you do make sure to coat them with some sort of corrosion preventive.

Yes you definitely need a new rod. I found some cylinders like that on Ebay, but shorter rods. An extension would work or a take a longer rod from another cylinder and put it in the short cylinder.

Well got the new cylinder installed and bled. The pump is still not working properly. Not building enough pressure to move the slides.
Gonna bits the bullet and buy one I found on EBay.
Picture of cylinders side by side and the extension, I used a coupling nut and Red Loctite.

Was it a Dewald pump on EBAY? If not, how are you going to connect the manifold with the valves and emergency hand pump?

That looks good. Lippert has test procedures posted to see if any other cylinders are bypassing. After looking at the piston seal in my kitchen slide, only half there, I decided to replace all 3 cylinders.

I found the culprit!
So I disconnected the lower slide hoses and just ran the bedroom slide. Wouldnít hardly move and wouldnít build any pressure. So the switched the hoses and just ran the lower end and the kitchen and living room went right out and the pump maintained pressure when closed.
So just ordered another slide cylinder for the bedroom.
The culprit.

Yep, that's it. You needed to get rid of the rusty one too.

Fixed it! Works great now.
I did have to cut 1” off the end of the shaft.

Looks just like mine except for extra bracing I added to the slideout wall years ago when the bed became detached from the slideout.

Being in the pump business I should have known it wasnít the pump.
So if you are having slide issues hereís hereís the simple way to test them. The fitting sizes are a 1/4 JIC. Get two 1/4 jic caps then you can isolate the bedroom slides from the lower slides. You can then see if the slides work. My bedroom would only go out a foot or so, but when I isolated the bedroom slide and ran the lower slides they worked fine.
I also got two test port fittings (1/4 jic )and gauges.
Hope we learned something from this. I think Iíll keep my Montana for a couple more years.
