Schwintek Madness

The wife and I had our first catastrophic failure this weekend. The full wall slide on our 2017 Hurricane 29M had issues. Friday we went to the NYS DMV to register the coach. The wife had made an appointment in mid-August. Before we even took possession of the rig. Friday was finally the day of the appointment. The previous owner had allowed us to leave their plates on it, (our insurance naturally), while we waited. We went and paid the sales taxes (ouch...) and got new plates. Saturday morning the wife planned to leave on a four-day solo (well, solo with the dogs) trip. Everything was packed but we went to take in the slide that we had extended the evening before in order to get everything loaded up and the rear of the slide wouldn't move.

Sigh.

Got the ladder out and start poking around. After some sleuthing, I find that the rear motor had sheared off the motor retention screw. The screw stops the motor from rising out of the bearing block. No screw meant the motor came out of the block and spun around, gouging the top of the bearing block pretty badly. I could not get the motor to reseat the index screws back into the four holes on top of the bearing block. The much more mechanically inclined brother came over Sunday and together we got the slide back in partway so we could access the motor from the inside. After ripping off the trim and cover plate my brother was able to remove the motor without too much more issue. Now that we could see what was going on we were able to get the motor back into place properly.

I worry a bit about the gouges on top of the bearing block not securing everything terribly well. The bearing block isn't terribly expensive but it is a pain to replace. I had to get a replacement screw from Home Depot. I went a bit larger than the original, a 5/8" #10 vs a 1/2" #8. But seriously, what an incredibly stupid design. They don't even bother to give you a threaded bolt hole on the motor to screw into, it just goes into one of the oval cutouts that surround the motor.

To round things out, when I was buttoning everything back up, I needed to put some sealant on the rubber trim I had pulled back on the outside so I could gain access to the area where the motor is. While cutting the tip off the tube of sealant I cut into the top of my left index finger deep enough to need four stitches at urgent care.

So the rig is working again. Slides in and out. Took it out for a few miles run to bounce it around to see if it would pop out. So far it looks ok. The wife took it for a shorter duration trip today and all is well so far.

So, any lessons learned? One, don't use the wrong tool to open up a tube of caulk or you'll bleed everywhere. Two, I need to get a collapsable ladder into the rig before we go out again. Three, I need to get a couple of slide locks in case this happens while we are traveling and I have to button up the slide and get the rig home or to a service facility with one of the motors disconnected. Four, the little Rapid Camp remote was super handy during this issue.

Hope everyone else's weekend was better than ours!

Ugh! Does not sound like fun.

My motto is "No task is complete until I bleed on it". And I do so with amazing regularity.

I keep a 6 foot collapsible ladder like the picture below in the rear bumper, where the "stinky slinky" is supposed to go. The ladder fits perfectly - snug enough that I added a piece of nylon strap to pull it out. It has come in handy several times. They also make an 8' version, which I keep in a shed at home.

That is amazingly compact! I think, given my height of 5'9" I need something taller to get at places like the top of the slideout. I have ladders at home obviously but think I will grab one of the Harbor Freight 14' (really 10') telescoping ladders to throw in the basement.

that outside 'set screw' and the motor's 'oval' hole is designed that way for a good reason - giving you the ability to much more easily 'set' the screw into the motor housing, otherwise if it was simply the correct 'size' threaded hole, you'd have to be so exact, without also being able to 'see' it, that it might be impossible to thread in. You'd be surprised at why somethings are sometimes done, even though your own experience might lead you to believe otherwise - it's engineering, and for good reason.

enjoy.

Glad you got it sorted out. I have a 29m as well.

Did you happen to get an inspection done before you purchased?

Not sure it would have been picked up. The screw clearly had just sheared off. The broken part was still magnetically stuck to the motor.

To answer your question, no. I brought my brother, a professional diesel mechanic with decades of experience, and previous RV ownership (which I have had as well, just not with slides) and we did a pretty thorough examination. Some areas have numerous RV inspectors around, they are more scarce in this area. The slides have gone in and out any number of times since we purchased it and we did two short three day trips with it without slide issues.

Thank you for posting your fix that means a lot for many. Hopefully I never have the problem but with people like you it really helps.

It comes in a 7 ft model as well. Iím your height and while I canít use it to get on the roof (rear ladder is for that) I can use it for everything on the side - all the way to the top.

My condolences. I also had slide issues at inconvenient times. Like you I think the design is not well engineered. Hope your finger does OK. Could have been worse. At least you were not pinching the tube of caulk between your legs while cutting of the the tip!

I have a Thor Chateau 31W with a full wall slide. In its 3rd year the slide started binding in the rear - starts together, then the rear slows down for a few seconds, then catches up again after the front is fully extended. It continued to get worse until the slide would stop and get stuck. The last time required 2 men and a woman to push as my wife was on the switch to retract the slide. It is now at Camping World - they are replacing the slide mechanism - $1150 for the tracts and the motors plus $2000 labor. (6-8 weeks). The controller never showed any fault codes. The slide needs 4 motors and not just 2 as they have to work very hard to move this heavy slide.

Just wondering. When you ran the slide out in the driveway, was the coach level?

2012 Four Winds 31L - sort of a 'sister' model to yours, different floor plan. But our slide is doing the exact same thing! Some times it works, some times not so much. What we have done as a temporary workaround is to have someone (usually me) go outside to the front end of the slide and as the slide starts coming out, push *in* on the front corner. I usually do it in short bursts until I see the back end get past whatever is slowing it down. We had initially tried to push *out* on the back end from inside the motorhome but that never worked.


Not sure if this is a 'sync' issue or if something is going out, or if maybe something is blocking the path of the back side...


Surely this would involve nothing more than maybe a new motor, right? I'm shocked that you would have CW replace *everything* at such a crazy cost...
