Main slide out issue - 2002 Patriot Thunder 455

<< < (3/5) > >>

Steve Huber:
Pierce,
Per the Owners Manual the 02 Patriot uses an SMC hydraulic system for both leveling and slide operation. The SMC Leveling System manual in Coach Assist shows the system hydraulic block has 4 solenoids to operate the levelers so I think that is what you are looking at. A wiring diagram in the manual also shows that the slide switch activates the hydraulic pump and the bypass solenoid. Since this solenoid is not shown as part of the leveling solenoid block, it may be in a separate location.

  I am not familiar with that system. If you cannot locate the remote solenoid pack for the slide, then you may try extending the room just short of binding and jack the room up with a bottle jack and 2 x 4 to raise it 1/2" on the side you are dealing with. Fred

Joel Ashley:
In Safari (Apple) I searched “hwh hydraulic slide solenoid” and then selected the “images” tab.  There were lots of pix, illustrations, and info there that you may find helpful in identifying your solenoid pac.  A similar endeavor should work if you use a different search engine.  In some hydraulics configurations there I noted the slide ones were mounted directly under the larger hydraulic leveler solenoids, a product I’m personally thankful not to have to deal with.

Attached is one representative image from the aforementioned search result.  Also there I was surprised to see images provided by a solo travel blogger I’ve followed for years, from when he worked on his slide or jack system.  I don’t remember him relating a slideout repair, but I’m old and forgetful, and his pics are there.  He is a retired engineer with many talents, so you might check into his related venture;  search “Chaos Leaves Town” or link from his images.

Pierce,
From the following thread: ".....my coach has the SMC system.  The reservoir is aft of the battery tray as Gerald said.  The pump is there also and controls the leveling system and the LR slides."

One slight emendation, Steve:  Gerald said it is forward, not aft, of the batteries.
“ …coach just inboard and forward of the battery bay.”  Jerry misquoted him in the following post.
