Me again,
I got some good info. regarding the fridge "flue" tube so I though I would try this one.
Our coach has HWH straight acting hydraulic jacks. One of them does not retract without prying it up with a six foot 2x4 and little old 220 lb. me busting a gut. If I forget to put a block under it (which I don't anymore) I will be in a world of hurt.
The jack seems to retract slightly better in cold weather.
Stuck valve or new piston?
If I need a piston, how do I get the foot off the old one?
Thanks again, Paul

The HWH jack is retracted by the Spring. You could need a new spring. The foot comes off by pulling down on the spring and unhooking it from the foot. Before doing anything I'd call HWH. They are very helpful and have talked me through a couple of problems. (800)321-3494 Bill Trout

I had the same type of HWH jack on my '99 Suncruiser. When it got to the point that I had to pry the jack up in place, I called HWH and they said that there was really nothing that I could do, except replace the jack. They indicated that it would likely just get worse and eventually it would not retract at all. I asked about putting in new springs and they said, "That's not the problem unless there is a broken spring." There was not. I had purchased an extended warranty when I bought the coach and they paid all but the deductible without any hastle. I assumed that it was common enough that the extended warranty folks were use to getting such requests. I now have an '04 Winnebago Journey that was new in April of this year and it has both rear HWH straight jacks that do not want to fully retract. I was 2,000 miles from home when it began and I went to Wal-Mart and bought a small hydraulic jack to put under the foot pad of the HWH to push it back in place. Lot easier than the steel bar I used with the previous coach. Of course, were the condition to worsen, I would not be able to get the new little jack in place until the jack was pried up to some degree. The coach is currently at the dealer and I have asked them to deal with the problem, since the coach is under warranty being only 6 months old. I am wondering if quality control is a problem with HWH. I agree that they are very helpful and sympathetic on the phone. On the new coach that I have mentioned, two weeks after taking delivery, the left front jack began to leak fluid. I thought a lose connection or a bad line to the jack. Nope. Turned our that the main housing from which the jack exits on its way down (or back up) had a small (and I mean small) hole right through the side. Of course, HWH provided a new jack, but each of these occurences requires a 140 mile round trip to the dealer and then, of course, there is the turn around time while the part arrives. HWH won't take the customer's opinion and send the jack. Has to be the dealer who certifies that the problem is what the customer states. So the coach has to be left (we tow the toad to get back home and then go back when the work is finished). Long story, but makes me question HWH and their great reputation has begun to decline with me. (On the caravan we just completed, one of the coaches with HWH equipment would let the street-side slide drift out going down the road (pulled out the strap). Turned out that it was poor workmanship. There are valves at the main pump. One valve was over tightened and had broken the seal (O-Ring, I believe) and the other one had been cross-threaded and began to leak. Air entered the system, so when it was retracted, the air compressed, but then it expanded going down the road and pushed the slide out. The owner lost three days of the caravan having the repair. Can't go down the highway with the slide sticking out from the side of the coach. Anyway, you can see why I begin to question quality control at HWH.)

Its pretty easy to check to see if its the jack or the valve that controls it. When the jack is not retracting, loosen one of the fittings on the jack, or at the valve. If fluid comes out of it and the jack retracts, you know its either the valve or a kinked line.

Have had similar experiences with HWH jacks. The problem occurs after sometime due to rust accumulating on the very inside edge of the cylinder ram end. This starts applying pressure to the seal located just inside of the cylinder on the ram end. There is very little room between the ram and the cylinder diameter. The rust growing increases pressure on the seal resulting in more friction between the ram and seal that cannot be overcome by the springs. HWH removes the cylinder and installs a rebuilt one that is usually taken off someone elses RV and rebuilt. This consists of removing the seal and cleaning the rust out and installing new seal and reassembly. This is ready for the next RV that has a slow ram. They do treat people very good at their facility. I have always been satified with how they do things. Charles

Very common problem with HWH. They replaced a slow jack under warranty when the rig was two years old. I have been putting up with both rears being slow, and listening to the annoying alarm. So much that I installed a cut off switch for the alarm, I still have a red light indication, but when the jacks are only one inch from being all the way up, I don't have to wait to leave and I don't have to listen to the noise going down the road.
About a month ago, I bit the bullet and brought two rebuilt jacks and put them on myself. They are up in less than 10 seconds now. They cost 152.00 each with shipping to Fl.
Based on my experience, they aren't going to get any better with time. If you are having trouble, just order a rebuilt one and enjoy them working normal. Big Bad John & Runaround Sue
