Curbside Slideout - 2006 Monaco Knight

[colorodan]

Having problems with the curbside slideout which has quit working. Raised the bed to gain excess to the motor to manually crank the motor by using a 5/8 wrench, as stated in my manual. Tried to crank the 5/8 nut and it just spins freely. My manual states

Did you disconnect the wiring harness????

[jacwjames]

Do you know where the slide controller is, there may be fuses.

I was having trouble with my front slide.  To troubleshoot the problem I actually disconnected the electric motor and used a battery charger to test and move the slide in/out, which showed the motor was good.

Then moved to other things to trouble shoot.

Jim,appreciate your reply. Yes I use that method with a battery pack/jumper on all four slides when the time to break camp and push the slideout switch and often than not they just don't work. When I'm back at home base, the coach has been in the shop multi times for this issue. Relays, house batteries replaced & etc. Right now I'm on the road staying in a warmer spot during Colorado winter. The curbside bedroom slide went in about 3/4 then stopped. Pushed the switch and nothing. Discovered the problem, my girl friend placed a small carpet behind the bed back in August and I thought nothing about it, for the bed just rolled on top of the carpet. So I tore the bed frame apart to have excess to the motor. Hook the jump box to it, (disconnected the harness) and all it does is run and no slide movement. My manual states that there is a rod that must me turned clockwise to locked the gear, and counter clock wise to unlock it. There is also a shaft with a 5/8 nut with a cotter key on the front of the motor. Used a 5/8 combo wrench on the nut and all is does is spin freely. So I was asking the forum for advice on that shaft which locks/unlock the mechanisum.

So the motor runs but the slide doesn't move. 

Sounds like you are going to have to dig into the gear reducer.  

I'd suggest you get a better picture of the name tag on the motor and do some searches and there may be some hits.  I know that there are some slides that have gear failures, my guess is this might be your problem.

Agree with @jacwjames.  The gear is nylon and can strip if there was some resistance at one point. i.e., piece of carpet.  Happened to me once when I was making a repair to the vinyl flooring.

The motor drives the nylon gear, the nylon gear drives the reduction gear, the reduction shaft drives the worm gear in the transmission, the worm gear drives the spur gear, changing output direction by 90°, the transmission spur gear drives the shaft with another spur gear that engages the gear rack that is bolted to bottom of slide floor. 

Either the cotter pin is broken or missing on the hex nut, or the transmission has likely failed. When turning the hex nut, as to manually retract the slide, the nylon gear is out of the equation.

The brass parts are failing in the transmission. It still worked, but had excessive play. (Last picture)

I that nylon gear isn't available as a separate part . . . could it be 3D printed with the right material?

I ordered a metal replacement for the nylon one online and posted the info in a previous thread about my bedroom slide failure... let me see if I can find that post.
