HWH Leveling System Tank Fill
« on: April 09, 2021, 12:44:02 pm »
I finally found the reservoir tank for the leveling system.  Check the level.  It is low.  Question is:  how the heck are you supposed to fill when it has to be filled at the top and you have only about 2 inches-maybe?

Thank you very much for the answer.  At the time I posted the original I just wasn't thinking.  At lunch I thought of how many times I have used a pump.  Gotta start thinking before typing.  Again thanks.

I cannot find the reservoir tank for the HWH system. Can someone give me a clue as to where it is located on a 2551.  A picture might help me as well.

Thanks

Where was your reservoir located?  It might give me a clue as to where to look.

SUCCESS-Thanks everyone, finally found it.  Took awhile because we kept looking from the drivers side and could not see it but coming at it from the passenger side it was easily recognizable.

Boy the fancy leveling system surely looks complicated with all those wires and hydraulic lines.

There are a lot of things in life that look complicated but are nice to have.   HWH called me back yesterday and was on the phone for about 40 minutes walking me thru an issue.  Very nice company to work with.  Makes things less complicated when  a company actually has customer service.

I FINALLY found the hydraulic fluid tank for our jacks. It was my third trip wiggling around under the rig on sharp gravel so it feels like a big win. For those still hunting theirs, I had John work the jacks while I was under there and tracked the motor whine (saw a comment to do this somewhere on this forum). Add in several lights glowing red when I watched from the front driver area and I had a happy Eureka moment. Our set up has a welded frame attached to the left "beam" that holds everything up. It's behind our propane tank when looking from the driver's side. I was not tool equipped and it's hot here so one more painful exploration will be needed to determine if low fluid is our lazy jack problem. They do extend but then one or two will sink at random times.

Holly--

Certainly worthwhile to check the fluid level (especially after all the effort you invested to find the tank!).

However, while I'm not a hydraulics expert I have worked on and repaired a lot of hydraulic systems in the past. Typically, low oil level would not result in the problem you describe. In your system, the pump pumps oil through lines into the hydraulic cylinders to extend them. If you have low oil level, and the pump runs out of oil and begins ingesting air before the cylinders are fully extended, they would simply quit extending.
If your cylinders are all extending properly--but later one or more "sinks" that would indicate that there is adequate oil to fully extend the cylinders, but later some oil "leaked out" of one or more cylinders. The leak usually wouldn't be an external one--it would usually be an internal bypass within that cylinder or (more likely) an oil leak back through the valve that closes to "lock" the oil within the cylinder after it is pumped in and hold the cylinder extended. Either fault would allow the cylinders to fully extend normally, but then let one or more sink over time.

Good info Mike. I guess we need a repair shop that can troubleshoot jacks. We'll add it to the list.
