2009 Canyon Star Bedroom Slide

I just repaired a very major discrepancy with our bedroom slide mechanism. The shaft that extends the bed side slide twisted in half. Newmar was gracious enough to send me a new shaft at no expense in which I replaced with the help of my Son-in-law. Small area to work in to say the least. If you lift the bed and examine the shaft attached to the slide motor you will see that a square tube about 3 inches long is welded to the shaft to allow for bring in the slide should the motor fail. It is my belief that after examining the shaft that the welding was the culprit that caused the shaft to twist in half due to annealing process caused by the welding. This shaft is 3/4 in diameter and upon inspection the key was not sheared.

Same thing happened on my 2008 BR slide. I sent them pictures and they did not offer to send it an no expense, I did not press it as the part cost was only about $110 and my coach was over 2 years old. I also believe the welding weakened the shaft.



I have not torqued the Trantorque bushing to spec, left it so it would turn before bending the shaft again. I also made sure the pot on the slide controller was set to the minimum (which it was), the controller still does not shut power off the the motor when it stalls! I've thought of getting a new controller that has a lower current adjustment range, have not done that yet.

Stewart,
I do not know who you talked to but I called Newmar and spoke to Jeff in tech assist and he authorized the parts department to send me a newly mfg shaft with key. Do not know why key did not shear first nor do they. I brought up the welding process used to weld the square tube assy to allow bringing in the slide if the motor fails. If I were you, I would call them and tell them you spoke to me and wondered how they could send one to me free of charge. Besides they may have more data now and would be willing to reimburse your cost.

Also, they spoke of a box with a plus and minus turn screw to adjust pressure on slide (is this the control box you are speaking of if so where is yours located?) but i still have not found the small box they are speaking of. Since replacing the shaft now the motor makes a moaning sound when closing all the way unlike the sound the other slides make. They told me the box could be in a closet somewhere. Do you know what they are talking about?

Dennis, thanks for the tip, I'll call Newmar and see what they'll do.

Our control boxes are located in the Fresh Water basement compartment, they are velcro'd to the wall on the passenger side. They look similar to the first picture in 007's post. Intellitec does not have much info on them on their website (at least last time I looked) but here is a page from Fleming Sales with some info.

The screw they speak of is the potentiometer labeled "Current Adjust" Basically if the slide stops too soon you're supposed to turn the pot clockwise about 1/8 turn, that increases the current limit, sending more power to the motor. In my case I cannot get the motor to cut off, even at the end of travel. This causes the shaft to twist. I have the pot all the way CCW, which should cut off the motor when it sees only a little resistance.

If you read this thread it will explain how your control unit will work and states if pot adjustment does not work correctly you may need a new control unit.
If thats the case there are other links in Quick Tip's that have control units that may not cost as much as Newmars, same unit as theirs.
I wonder if you have the right control unit for this particular slide, the toque of these motors will move slide with someone sitting on your sofa.
