Solenoid Valve for hydraulic slide

<< < (2/5) > >>

KC Snellgrove:
Thank you all so very much. I will get out there tomorrow am to check it out. As for the solenoids they are on back order several weeks. Cannot get them..awh.

Joel Ashley:
Here's the way I think things are arranged for those of us with several slideouts, as partially plagiarized from another resource:

The slides are numbered one, two, three, four in a counter-clockwise direction starting with the one behind the driver.   So if you had 4 slides hydraulically operated then the streetside frontmost is #1 and the front one on the curbside is #4.

The hydraulic solenoid valves are numbered similarly starting with the set closest to the pump and moving outward. So the set closest to the pump would be for slide #1 and the set furthest away is for slide #4.

The wrinkle for us with 4 slides is that slide #2, usually the bed, is electric and that implies slide #3, curbside bedroom scissors-type, would be run by the second solenoid set.  Set 3 would then be for the curbside front slide.  I think solenoid #4 is for hydraulic jacks if you have them.

Hi I have a similar problem on my 2005 3 slide Monterey. I believe that there is also a check valve in the system, somewhere. I find that I can create the problem if I do not move the slide 100% and out and build a little pressure then retract it. When the slide does creep cycling it all the way out and back reseats something and it functions fine until I don't completely cycle it again. Also in the hydraulic loop when creep occurs, I think there is some diagnosis required as to which solenoid may not be sealing or if it is the check valve.  You might want to look at page 8 of the attached document if this is the system that you have.   

Just a thought.

Best

Joel,

I have a 4 slide 2005 Monty and have a creeping bedroom slide, but mine seems to be attributable to a leaking solenoid evidenced by a recent puddle of hydraulic fluid on the ground to the left of the front step.  I wasn't sure which one was leaking so I used Gunk and my pressure washer and to clean the manifold.  Reading your helpful posts I was expecting to find four solenoids each for in and out including my hydraulic jacks, but my rig only has three of each.  After a bit of head scratching it occurred to me my RVA jack system is completely independent from the HWH slide system with it's own pump, reservoir and solenoids.  Nothing is a given with these custom coaches, year, model and options all can and will throw us curve ball.

And then there is the unexplainable; it's been over a month and no leak is evident and the slide is not creeping. I didn't know Gunk was a sealant, go figure.  Now if only the Hydrohot will fix itself and fire up.  The adventure continues!  Happy holidays to all.

On our 2005 Monterey, the bedroom slides are electric, so no hydraulic solenoid. We have only 4, 1 in for curbside front slide, 1 out for the same; 1 in for the street side front slide, 1 out for the same. We have air leveling only, so no hydraulics for any jacks.
