Bed Slideout Out - help!

[pflightnut]

2008 Monaco Knight 40 DFT - the bed slideout went out today, but won't come back in. My wife didn't hear any odd noises, but the motor just hums when the button is pressed to the "In" or "Out" position. I can see I have a big project ahead of me after reading these posts:

My question is the step-by-step (I hate tearing into things and tearing them up). Obviously, some of the following must be done.

1) remove the bedding
2) detach the flat platform that the bed rests on and get it out of the way?
3) remove the cover on the internal box to get access to the slide motor and gear track?
4) while watching the motor and gear, determine what is spinning. Is some shear pin lying on the floor? Is the gear torn up? Is the gear track chewed up?

The slide has always made a slow click-click-click noise while going in or out, and at the end of travel on either end, the clicking gets faster. Now, with no travel, the motor just hums.

Any thoughts on whether I'm overlooking some steps, what else I might have to remove or get out of the way, etc?

At least we just got home from a short trip and this happened while cleaning, and we're not in a campground !!! Thank the good Lord for that !!!

I have another problem with my slide topper (Carefree XL 2 sections that developed on the way home, but that's another post).

Thanks in advance for pointers and advice from prior experience. You guys a a tremendous resource and encouragement.

Best,
Steve P

P.S. I'll post some pics from my phone when I get started on this new fun on Saturday.

As you mention, determine if motor hums and IS spinning or motor hums and IS NOT spinning.


If it's trying to spin, it's possible the bed frame has come loose from the slide and has jammed. That is very common and a fairly easy fix if you're handy wood worker.

If motor is spinning, it could be the pin you mentioned or one of the gears is stripped. Last I heard, the gear is difficult to source.

And of course, if the bed frame came loose and jammed, causing the pin or gear to fail, would be the worst scenario.

Well, the motor hums, but neither the motor shaft with the cotter pin, nor the shaft going thru the slide/gear rail is turning. The silver cylindrical housing would appear to be some kind of transfer gear I guess? Maybe it is what clicks when the slide is going in and out? The black shaft in the third pic has a 5/16" hole thru it. Might that be to insert a rod to turn the gear inside the slide manually? Diagnosing the problem is baffling. Repair seems a long road at the moment. Any and all advice is appreciated...

[windsorbill]

the clicking is normal.

Assuming the batteries are fully charged and good.

First thing I'd do is check to see if the bed is rolling on the rollers. Have you noticed any wood chips/shavings on the floor when you put the slide out?

If the bed frame comes loose where it's screwed down to the slide floor, it can cock and bind, causing your issue. That is a very common problem. I know of at least a dozen owners that have had to redo the bedframe connection, including me.

More than likely the plastic gear broke.



Using a drill motor with a socket, you can retract the slide. You will need to drill a hole in the bed box to do this. But it is a lot better than trying to retract slide with a ratchet wrench on the hex nut.







When you start retracting the slide you will need the extensions.



Put socket on the hex with the cotter pin.

Harry,

I forgot you documented that repair. Do you know of a source for that gear? I heard it was hard to come by...

[Timaz]

Instead of drilling a hole you can use an angle drive attachment for your drill and just keep the bed up. Harbor Freight has them.

Harry - in this other thread (https://www.irv2.com/forums/f54/lipp...re-411514.html ) there is a link to a gear that worked for Skip426:
https://www.walmart.com/ip/Taluosi-M...ture/917319995


Do you (or anyone) know if this is the right gear or where to get the right gear (assuming I confirm the plastic gear is the problem tonight when I pop the cover off)?


I'll also reach out to Skip426 if he doesn't see this thread.


Thanks again everyone... I'm preparing to move the slide in with the drill if the weather gets rough here. Otherwise, I'll wait until I am sure what the problem is.

The new gear is metal -- Ebay or Amazon should have them --

The hole was forward thinking when my buddy's coach had the gear let go. I wanted to be able to move my slide if my gear failed.

I took apart my buddy,s old motor, that he saved for me, to see what the failure was. I found the plastic gear had cracked radially from center out to the teeth.



At the time, no separate gear was available. As our two coaches were built weeks apart and both lived in AZ, I bought a motor/gearbox assembly for mine, just in case.

Sure enough, a year later mine skipped for a split second as the gears meshed over the cracked plastic gear. I put the new one in and tore mine apart. Yup, it was failing.

I’m glad I replaced the assembly, from the looks of the gearbox. The grease was full of brass shavings. The whole thing was worn out.

On my 2007 Dynasty the slide would not go out. I raised the bed and got on my back under the center channel that holds the track that moves the slide. The 2 set screws on the gear that drives the slide were loose and had slipped on the shaft. I raised the rail and moved the gear and tightened the set screws. I don't know if we have the same arrangement but i was happy with this fix. Easiest thing i ever repaired on a MH.

Do you have any pics you could post? I tightened the motor mount. I'll do anything else that needs doing while I have things apart. I don't exactly see or feel the gear you describe. My slide upper rail with the toothed track seems to set inside the lower rail. The shaft goes in one side and out the other. Presumably, the gear is on the shaft, but hidden between the upper and lower rails. Do you (or anyone) know how to get to this gear?

[pflightnut]

I took the black cover of the gear housing, and sure enough, the gear has cracked (see pic). Now I am on the hunt for a replacement. It's a pretty complex gear. I didn't see a part number. And I wanted the slide in so I didn't disassemble and degrease it. The drill trick with long socket extensions took care of that. Has anyone bought one of these gears recently?

[pflightnut]

I ordered the gear in the Walmart link above... and will report back sometime after it arrives on Sep 6.
