HWH hydraulics

I need a bit of help from the experts and I know that there are some of them here. I have a 2008 Winnebago Aspect. I have had trouble with the rear jacks returning to the "docked" position in the past, but they did so...until now. The passenger side rose about half way to its place. I helped it go to full return with a floor jack. It did so without resistance. The driver's side came up about an inch from the ground and stopped. I used the floor jack to raise the coach high enough to get the head of a sledgehammer under the pad of the jack, then after placing the sledge head under, released the floor jack. All of this was done while I had the system active for auto-store. The HWH jack did return a bit, but not to the highest level. When I used the floor jack to raise the coach again, the HWH extended the inch or so back to the original position of being stuck. If I turn the auto-store feature on and off it sounds as if a solenoid is clicking in and out, but the jack will not return to the "stored" position. I have also tried the manual retract button to raise the rear jacks. Nothing seems to work. Comments, opinions, suggestions?

Larry if you tell us what kind of a MH you have, you'll get more answers. You should have release valves near your hydraulic pump. There should be 4 of them. You can try to open the valve which will allow the cylinder to retract. A sticking valve can cause this.

Open the T handles on the rear jacks. This allow the fluid to return to the tank. If they still stay down, the trouble is in the jack itself. The packing is binding or the shaft is bent. Either way, they will have to be rebuilt.

I was just under my neighbors Winnebago MH and he was having issues with the jacks not retracting... while the jacks were extended I washed off each jack with a rag soaked on acetone... as I started this process... the wet rag would drag in the ground/chrome surface... as I worked the rag I'd get the rag to slide smoothly across the surface and on each jack the rag would come back black from dirt... in his case this dirt was not allowing the springs to push the jack leg up into the housing.. the dirt would drag on the seal and it would either run so slow or stop...

If you've tried this.. and the rag runs across the ground/chrome surface easily than of course the seal is damage and you'll need to rebuild the jack...

Hope this helps...

HWH hydraulics

I assume from you signature block you are not the first owner of this coach.

The first thing to do is clean the ram (the silver piece). Get a clean rag and WD-40, DO NOT USE ANYTHING ELSE or you stand a good chance damaging the seals!!!! Spray WD-40 on the ram and wipe it with the clean rag. Do this until the rag comes away clean after you wipe it. Then spray the ram one more time, leaving the WD-40 on the ram. Do this to all the rams. Now place the system in auto store. The jacks should all be retracted in about 2 minutes (the travel light will come on). When they are retracted they are sitting in hydraulic oil being lubricated, the seals wipe the excess oil off the rams as they extend and dirt off as the ram is retracted. If this resolves the problem extend and retract the jacks several more complete cycles. Be sure to allow the retract cycle to run until the system shuts down by itself each time, this is over 5 minutes.

If this does not fix the problem you most likely have a bent jack or something else wrong with the system and need to get it to a HWH service center. I assume you have sufficient fluid in the tank. You could also go to the HWH site http://www.hwh.com/homeland4.html and get the manuals.

Or call Stewart's HWH service in Elkhart. He is very knowledgeable and helpful. He is listed on the HWH website.
