Slide won't open completely on one side...

[steelheadbluesman]

My bedroom slide is off a little, has become a little noisier, and locks up with one side not out enough to seal on the inside. So the outside gasket is functional, but I can get my fingers between the wall and the inner seal at the bottom left. The top is tight, and the other side is tight all the way up. The machinery is under the bed. Can an adjustment be made? I'm concerned that this could get worse... Thanks for any advice!

you don't say what brand of slide you have. it sounds to me like you are low on fluid and have air in your system.
check for hydraulic leaks in the lines. repair any leaks found. then, the next time you have both slides (front and rear) retracted fully and the jacks retracted fully, make sure that the hydraulic reservoir is full. mine uses dexron 3 atf. hwh fluid is the same thing without the pink coloring and is much more expensive.
operating the slide several times with a cooling off period between times for the hydraulic pump motor will eventually bleed any air out of the hydraulic system.

Make sure you consistently use the techniques explained in the coach user manuals and HWH website concerning extending the time the retract or extend button is presses. You need to give the slides an extra 10 to 20 seconds of actuation time after they are fully extended or retracted in order to alleviate any unequal pressures/quantities between the forward and aft extension cylinders.

Paul, can you tell me where you saw info about the "extra" actuation time? I've held the buttons, but no help. There is a manual method to "realign" the two drives, but I'm waiting to discuss it with a Kwikee tech before I do it. Thanks for the help.

Also Dan, are you saying a good quality ATF is the fluid to use in topping off the reservoir? I'm also wondering how the system can bleed itself? Thanks for your assistance as well!

Adding to Paul's response, recommend that you check for updates to your HWH Operating Manuals/Supplements. Winnebago Industries Operators' Manuals

hwh systems are self bleeding. hwh uses colorless dexron 3 for hydraulic fluid. i don't know what kwikee uses. which system do you have?

My reco is do NOT continue to press the extend/retract button for an extended period, like 10-20 secs, after cylinders have been fully extended or retracted. Continuing to press on the button increases the hydraulic pressure to the point where the over pressure value will open. This puts a very unnecessary and very HUGE stress on all of the hydraulic components.. the lines, the seals, the pump, the valves, which will eventually lead to premature failure of any or all of these components. Listen to the load on the pump.... an additional 3 or 4 seconds should start building huge pressure which will start dragging the pump speed down. At that point the pump is drawing huge amounts of current and everything in the system is being severely and unnecessarily overloaded.

Once the slide is totally in, or out, and the cylinder has reached it max travel limit then within a second release the button. This brief additional second is more than sufficient to build adequate pressure to hold the cylinders in place which will hold the slide in place.

Dan L: Assumptions and wrong assumptions!
My info comes from the HWH website, (http://www.hwhcorp.com/), for my specific system. I assumed your system was also HWH. So sorry, it may not be applicable to your system.
In my HWH system when the cylinders reach their far end of travel and if pressure is maintained for a short time period the design allows for an equalizing of any small fluid differential between the cylinders. Perhaps 5 seconds is more applicable than 15 for such purposes and I should have referenced the HWH website instead of paraphrasing. I hope you solve your problem. And when you do, please pass along the solution.

Paul, I also hold the "Extend" switch for three to four seconds after the room is fully extended. This is per the HWH "Room Extend Procedure" (MP35.9300, 24 Apr 03) -- HWH cautions to not hold the "Extend" switch for more than ten seconds. HWH states "This assures proper pressurization of the cylinders."

Hi, your coach does not have HWH Slide Mechanisms. There is no Hyd. Fluid used, the slides are electric. The rear slide has only one screw, the front has two. I would contact Winnebago to find out if there is an adjustment to correct this problem. Has Kwikee responded to your question?
Please let us know when you find out what has caused this problem.

Thank you and good luck!

Thanks to all. You are correct millrv, my system is electric. There is a procedure whereby you use the extend/retract buttons to "even" out the screws. But my rear slide is the problem, and if you are correct and it only has one screw, how does it even out? I'm wondering if I can use the hand cranking tool to push it? I will contact Kwikee and get to the bottom of this, then post back. I appreciate all comments.

Please do post your findings as my 35L (08) always has one side that makes contact first by about an inch and a half. I hold the button till it cuts out and it does even out.

I googled Kwikee today, got a single 800 number, but it was "no longer in service." I'll try to locate a number after talking with Winnebago tomorrow.

Roger your post Zippo, I'll post any info I can get.
