Hydraulic legs.

What type of levelers do you have? Was it all the way up or was it still touching the ground? It is not unusual to have to adjust level after sitting for a while. If the jack comes all the way up and you have HWH levelers, then I think you're going to need a new jack.

Or just maybe a new solenoid. We had this happen on our right front jack on our HWH system. The solenoid for that jack would not close all the way, and even though the jack would go down, it would slowly come back up.

Although I don't have a Class A, like many with large 5'ers I have hydraulic levelers. If you'll permit one of us "trailer trash" folks to post in your Class A forum, I had a similar experience with my HWH levelers and it turned out to be a solenoid.

It would seem from what you say that you have a three point system, with two rear and one front jack. That then would indicate that one jack has begun to leak. I would check first to make sure that no leakage was to the outside of the jack, leaving fluid all about it and the pad. The next thing to check is the valve that releases the fluid from the jack to return back to the reservoir. If yours are power down with spring return, there may be only one valve with two positions for supply and release. As part of the testing, I would check to see if the jack will level back or must you retract it and then put it down?

 

The make and model of leveling system would help to give more specific information.

Its a Power Gear system, 3 legs. I just checked the reservoir with legs retracted and seems a bit low. Going to add a little fluid and try it again as we go down the road. I did notice one time some fluid on the ground under that leg but it hasnt leaked since. Wiped off the leg as it looked like there was some grit on it.

It could be more than "a bit low". The leaked fluid/oil may have been enough to allow air to enter the system. Since air compresses, the jack will respond to the pump, but over time the air allows the jack to respond to the return springs.Top-off the resevoir, operate the system several times, recheck oil level.

That of course will not resolve the leak, for that the cylinder must be rebuilt. Any good hydraulics shop should do that, or have Power Gear replace with a rebuilt one.

That said, Paul may be right.

Well the saga continues......went to retract the legs today and they retracted but the indicator light shows " legs down" and alarms if I try to move. Checked fluid level and even tried adding some but its full. Checked the float switch for continuity as per troubleshooting instructions and everything is checking out as normal. So I made sure the legs were indeed up , double checked , and pulled the fuse to disable the system and continued on our way. I need to download a comprehensive troubleshooting guide so I can figure this out. Starting to wonder if it is air in the system. These Power Gears are not spring return or at least not with external springs.

 

Drove to our next destination and went to dump the air to settle the coach for the evening and the dumpswitch decided to not work. So I had to reinstall the fuse for the power gear system and dump the air that way. They must be connected.

It may help if you use this Power Gear info to compare to what you have. It tells us that Power Gear jacks that are powered both ways will have a hydraulic line at both the top and the bottom, while spring returned ones have only one line at the top. You may also be able to get more technical data from this website.

 

I would inspect the jacks to see if there may be some sort of sensor on each jack to indicate that the jack is up. If there is a sensor there should be wires to it also and you may be able to test for a failure there.

Well.....huge learning curve here......feel kinda dumb but I was looking at the wrong reservoir. LOL. I thought the little reservoir up front was for the legs...nope....its for the hydraulic ram that pushes out the front of the MH for getting at the gen.

 

The actual Power Gear reservoir is at the rear of the coach by the air cleaner. It was down on fluid....ended up adding a quart and a half of ATF and then the light went out on the dash. This system works with a float in the reservoir so when the fluid goes out for jacks down the float switch closes. Then when the legs are retracted the fluid returns to the reservoir and the float rises and opens the switch.

 

The dump switch is also working again so all is good. I do have a hydraulic leak on a rear leg so will have to address that along the way somewhere but I rarely need to use the legs as I can usually park on a fairly level spot so I dump the airbags and settle the coach on the frame and call it a day. I am hoping that these hydraulic rams are normal rams that can be rebuilt. If so I will do it myself when the opportunity arrises.

Not bitter at all. Just pointing out what several people who campaigned against separate forums for different types of vehicles felt; that most of the systems are the same. This question would probably have been better asked in the general forum or in the technical forum. This kind of issue is not unique to Class A's.
