YIKES... the slide is racking!

We keep the coach at the house with slides in, so the toppers don't get weathered. Coach has been parked since October with occasional engine and genset starts, but no slide activity.

Yesterday I wanted to open the slides and the main slide's front section hesitates before it begins it's travel. That makes about a 3-4" rack and when the rear gets to the end of it's travel, everything stops; leaving the front about 3-4" from fully extending.

HWH pump with fluid full. Coach is fully leveled. How to diagnose??

If your slide is electric, check the drive tube (square) that connects to the motor, check the tube near the part of the slide that didn't come out all the way and see if there is a shear bolt that broke. This would cause that part of the drive tube to free spin.....Bruce

Slide is hydraulic. Equalizer system. Nothing impeding movement that I can see. Fluid level in reservoir (with BR slide extended) is about 1/2" below the Full line.

I'll add fluid up to the Full line and see if that changes anything.

I believe you should check and/or add fluid only when all slides and jacks are retracted.

It's a larger reservoir, so I added a quart of ATF. Enough to cover the Full line no matter what, and not enough for the pump to puke excess.

No change. Matter of fact, the racking seems to get progressively worse.

I think the first clue is needing to top off fluid. That isn't normal.

Thanks OO7. I'll give them a call in the morning in order to trouble-shoot the system. Tubes and slide rails a bright and shiny, so nothing obvious.

The fluid level drops as it's used to extend the the slide(s). If you fill the reservoir when slides are extended you will have a mess unless there is sufficient expansion area above the fill line in your reservoir. Check fluid and only fill when slides are retracted. I'm recommending this based on personal experience.

Agreed. The reservoir hold several gallons and the FULL line is about 2/3 of the way up; leaving a lot of space.

In this case, fluid isn't the problem. The front of the slide seems to hang a bit while the rear moves as it's supposed too. This racks the box and eventually the box can't move any more.

OK, a call to Equalizer got me onto a path. The tech said that...are you reading this????????????????....

...whenever we Extend our slides, do not Retract them in the middle of the run. They should fully extend before we retract them; otherwise the timing can get thrown off.
I remembered doing just that a week ago while showing somebody the MH. It was raining and so I just extended the slide about half-way and then brought it back in to avoid getting the topper wet

He gave me the drill for how to re-set the timing, but I'm taking it to the shop just to be sure that I don't mess something up.

This is a new one to me, since I Assumed that the hydraulics applied equal pressure to both cylinders. I guess not.

Sounds like setting the timing Ina Schwintek electric system

Do you have slide toppers that could be hanging up the movement? We did.

Our toppers are fabric on rollers, so I really doubt it. We keep the slides in just to prevent the toppers from getting weathered.

Of course, in a perfect world, the tech would find something like that and free it up...charge us $20 and then offer to buy lunch.

Like I said, in a perfect world
