On mine, the slide room roof had sagged in the middle (maybe from having the slide out 80% of the time for 20 years, and the bladder pushing down on it?

MOT did a LOT of work to get the sag out of the room - We all thought it was the bladder, but that is NOT what it turned out to be.

on a 2000 you will need to bring the room all the way out of the coach to work on the bladder- Most shops use a forklift or two or an adjustable staging system on wheels

Not for the faint of heart....

Tim I want to say your experience was a spot on description of mine. Top and bottom both were bowed to the point that there was a 3/16+ gap. I was able to get a lot of the bow out but once the pressure was on the bladder it would start bowing back. The guide pin or block was needed to control with slide open. No issues when closed the skin easily supports. Still need to make upper guide. Next week. I used a large pallet and four adjustable jack stands to reinstall. Forklift to remove and secondary safety support. Good stuff for sure. Thanks for your insight.

Be nice if you could sacrifice part of a clean new cheap paint brush on the inboard side of your roller, just to sweep loose stuff off, like gravel.
Just a thought.

Really out of clearance. The door for the couch drawer will probably need to be relieved anyway to clear roller

Pressure regulator would sometime start leaking air. Removed the rubber seal inside sprayed with freeze spray and with chucked up in drill redressed face on scotch bright wheel. In the first photo if you zoom in you can also see the little rubber seal in the middle of the plastic block. Smooth in the second photo. Back in the early 90 I worked for a very smart guy in the field of rubber products. Taught me to tool orings and other weird rubber stuff by freezing. Works great cold but impossible at room temperature. He also held the patents to the laytex cross your heart bra. Super guy. Since passed.

Thanks for the great tip, freezing rubber to machine. Respect for your component level repair, the ultimate form of recycling.

Would have been a good idea to try on plungers on six packs. Jim

Started making upper guide block and roller to secure slide from bowing with slide extended and bladder inflated. This will prevent possibility of bowing and leaks. Roller stops on flat section when fully extended. Currently only will deflect slide top upwards about .050" from relaxed. Will fit under cover and be unseen. This also acts as the center stop similar to the removed factory stop with the opposing 45 degree plates. Outer two will be retained but will do little if anything. My center stop was actually below its other half and doing nothing.

Looks good Scott, will you weld this to the top truss?

Going to weld to a plate and bolt to upper truss with a bunch of 10/32 grade 8 screws. Small but in numbers quite strong and removable. Similar mount for roller on slide.

Upper half done. Just need to install and build the bottom roller half. Note on forth picture the round shinny disc. Its a earth magnet to collect drill cuttings.

Other half of upper mount finished and installed. Lifts a little before roller is on flat area. Virtually no sag now in upper slide surface when pressurized.

So im getting much closer to having a functioning slide. Ive opened and closed the slide more times today than I have since we purchased the coach. So one has to laugh, Ive been fighting with the forward slide stowed sensor for the past couple of days. Can trip externally but can't get it to function correct. Someone had swapped the wiring so the forward stow position forward is actually the rear and vis a versa. Much easier to t/s when your working on the correct sensor. So I wonder how it could of ever worked Especially with the bow that was in the top separating the sensors from the trip magnets additionally. Sensor part Number #19988. I was able to get the rear sensor to adjust in and work correctly marked as the front and suspect my actual forward sensor marked rear is failing but will operate with external magnet. It also could just be a decaying magnet? The magnet is mounted in the lock receiver and suspect HWH would want the entire block. I bonded a magnet outside the slide on the fiberglass and think it will work fine. Bladder pulls back 1/4 inch and magnet is 1/8" thick. Also the sensors are polarity sensitive to the magnet. One direction and they trip way to early and reversed the function real nice when over center. Will order a pair of sensors from HWH if I can't source. Also I opened up the internal magnet access inside slide cabinet and verified magnets were up against fiberglass. Nylon rollers I added on the front and rear allowed easy adjustment of slide vertical position. When fully extended rollers become unloaded. I originally was concerned the would load up when extended but dont.
It's really nice how much bigger the coach is when extended. Im confident Ill have a complete stowed, extended, stowed cycle this week.

Well I finally operated the coach slide from closed and locked to extended and retracted and locked from the drivers seat. I know it doesn't sound like much but it's been years in the works. Very rewarding to actually have in work once correct. I am still going to order two slide stow sensors before I finish up. Next is to finish up with replacement air compressor so it can supply needed air. One big leap forward though. Both slide open guides worked perfect. Zero flex when inflated while extended.

Scott, that is amazing. That is one project I'm not qualified to take on. Congrats.

I'm starting to plan my trip to HWH in a few months to fix the leaking bedroom bladder. But, before I take on a 2000 mile round trip from N.J. to Iowa, I'm hoping that I can find a place that can do this work closer to NJ. Does anyone here know of a place closer to the Northeast?

Neither was I. Bedroom bladder on your coach would be much easier to do. Smaller, no delamination issues, and your slide pushes in the change the bladder. Huge difference.
Good luck. Reply #57 is a huge timesaver. HWH never has done it this way. Two hours for one person to remove adhesive on big slide. Was a huge deal for me! New seal is way better.

So as the saga continues the last couple of days off I worked on the little Thomas compressor. I removed from coach to facilitate working on it. Thought I would pass on what I learned. Roger has had several posts which I used to help figure this little guy out. There are several things I didn't understand basically till I got to the end of sorting out leaks. So there is a line from the compressor head to a regulator that vents to the atmosphere when pressure is exceeded. Line continues to the water separator filter. On the bottom of it is a normally open solenoid drain. When compressor runs it closes. When off it opens and vents water to the atmosphere. As the air is leaving the filter housing there is a check valve. On the other side of the check valve is a Tee fitting branching off to the pressure shut off valve, line 75 and line 57. Line 75 to the bladder tank and control valve exits the Tee fitting thru a normally open solenoid valve. Both lines have separate check valves only allowing pressure to exit away from pump. Line 57 Feeds the safety valve manifold down stream of it. so when the safety valve is above about 60 psi it can backfeed air to the check valve where it is stopped. At below about 50 psi the aux compressor can feed air into manifold past the check valve so leveling can be accomplished. So I was confused what the aux air valve solenoid function was being normally open. When there is a raise command threw the HWH controller it sends a signal to close the aux air solenoid to prevent air going to bladder system till command is done. This forces all available air to line 57 and eventually to the six packs. Command goes away, aux air solenoid relaxes and air can continue to bladder system as needed. So when I first started compressor it would run till charged then cycle every minute. The aux air solenoid had a failed oring (metric) and this was causing the rapid start, shut off cycle. Prior it would run to bring up bladder tank and then start its off on cycling. Ive got the leaks resolved I believe, but have not reinstalled compressor yet. I did notice a small leak around filter base and a very small leak at filter solenoid valve. Resolved filter base and ignored drain leak because only present with pump running.
Also I have removed the Tee fitting from the check valve after the filter. This is were my ARB compressor will be installed eventually manually/automatically controlled. At this point ill be installing a additional desiccant filter between before the split to lines 57 and 75. My bladder tank may have never been drained in its life and i'm concerned about all the water I initially drained. This may be a non issue but its going in. Ill post picture as I get to that point. Tee fitting will be after desiccant dryer. Desiccant dryer will remain under pressure except for service. Thomas compressor will still function as before. During manual level adjustments ARB can be turned on. For slide bladder vacuum needs it will automatically be commanded on. I had purchased a Vacuum pump to provide vacuum but currently going this direction. I may eventually use the vacuum pump but not at this time. ARB will also provides air for tires.

So I do have one question Im hoping some one can answer, were is the intake for the compressor? All I can figure is it must be internal?

Scott,

On the one I have on the shelf for loaner the intake is on the head just opposite of the discharge port. I have no idea as to if all are set up this way or not. There isn't a line that runs off just a dust filter.

Well that what I was expecting but in the opposite hole from the outlet is a plug.

Here are plumbing and wiring for the 2001 coach. Three different air system drawings in this year, minor changes.

I had two of the small compressors, the OEM had a filter on the end plate.

I have a bigger Thomas by itself on a easy to remove board where all of the stuff was before.

The rest of the stuff in on a panel on the back side wall of the bay. Easy to service. Connected as they are in a 2003. I have a much bigger dryer to connect when we get home.

And an ARB backup/utility compressor, ceiling mounted on a panel bolted into steel. Didn't quite finish all the connections before we left in Dec. Three way valve, either or both. If it is not selected for air system it provides utility air (bike tires etc) you can get 2 of the ARB compressors for the price of a big Thomas compressor.

Last two are 2003 variations.

Roger that is very similar to what I will end up with. I like the little Thomas for the bladder pressurization and the ARP for everything else. Using the 9700 wire will interface it with the ARP in the auto position. Still will have manual override when i want. 👍👍

Scott, I have the bigger compressor but yours might be the same as far as air intake. The base of where the compressor sits on is where the intake is.you can see the black hose going from the base up to the compressor. The bolt and nut in the middle of the base holds the cover for the filter.
