Main slide out issue - 2002 Patriot Thunder 455

<< < (2/5) > >>

Joel Ashley:
As I recall, the solenoids are in an order on the manifold relative to the slideout position around the coach, with streetside front being #1 slide.  On ours the bed slide is electric, so the curbside bedroom slide (scissors action) is hydraulic slide #2, and the curbside front is slide #3.  The genset slide may be #4 unless it’s electric.  Forgive the limitation that I’m unsure, after all that, which side of the manifold is solenoid pair #1 🤔.  Each slide has an extend solenoid and a retract solenoid, opposing one another.

The manifold is atop the tank, darn it, and not as clean to get at as illustrated in the owners manual.  But yours is a very different model of coach than mine, and the subject arrangement may be quite different.

Great stuff guys,
I now know what to look for and how to relieve that pressure.  Pictures and written instructions super helpful too Joel!  From reading description, it seems to indicate loosening the "nuts".  I took that to mean just loosening all 8 nuts (both sides of all 4 solenoids).  Do either of you see any problem with just doing that as opposed to trying to decipher which one in particular controls that main slide?

Fred Brooks:
    Pierce,
  I guess you could do it that way, personally if you choose that method you may disturb the inner needle and seat arrangements and create another issue. I would identify the 2 opposing solenoids that operate the slide room. Once you relieve the hydraulic pressure in that system, you can t-shoot your issue. Hope this helps, Fred

Joel Ashley:
A slight correction in my photo, Pierce;  the arrow identifying the pump motor should point more to the left.  The motor can be seen hiding behind the “S” in the yellow word,“Steps”.

Keep us advised of your repair adventure.

Joel

Pierce LeFevre Jr:
More thanks Fred and Joel.  Good call Fred not to unseat anything unnecessarily.  Crawled underneath today and my setup is totally different.  Found the hydraulic distribution block at the curbside rear.  Has 8 hoses coming into the top of it with 2 hoses coming out of the bottom that run to a nearby large cylindrical reservoir.  4 solenoids are mounted horizontally sticking out of the side of that distribution block with one large nut on the end of each solenoid that appears it could be turned with a socket.  Above those 4 solenoids and hard to see and photograph appears to be one cylindrical block coming out of that main block with a nut which would also accept a large socket.  With no service manual my latest challenge is now figuring out exactly what to turn on this device to relieve pressure.  A sticker inside a rear bedroom cabinet door lists many of my coach's systems, but unfortunately no mention of slide or slideouts.  It lists the Levelers manuafacturer as RVA Jll, but don't know if that's the company that might have also supplied the slide mechanisms?  Anyway, that's where I am at the moment.
