Slide Out Problem with Chain.
Any help or suggestion would be appreciated.
The problem is with the kitchen slide on an 2009 Dutch Star. The rear chain on this slide has been popping. This started last fall with unit only being 6 months old.
The chain only pops at the end the extension or retraction. It almost seems like the sprocket is being turned one chain link to far. The front chain is fine. You can tell its going to happen when looking the shaft to the left (going towards to the rear of slide) of the motor. It looks like it comes under tension with a slight bend, then the chain pops/slips. It does not happen every time. You can cycle the slide 10-20 times and no issues. Then the next time the chain pops. It may happen for only 1 cycle, or may happen for the next 6 tries, then the slide runs fine for another dozen cycles or so. Took it to be looked at a Cumming Coach Center. They found an adjustment to the rear slide lock need to be made, but of coarse while there, the chain worked just fine. Brought it home, work fine for 6 cycles, then started all over again.
Last fall they made a slide adjustment. Work fine for a dozen tries, then then chain popped and broke at the master link. Tje chain was replaced and slide adjusted last fall and put away for the winter. The slide was again adjusted, fine tuned a Newmar tech this March, worked fine until 3 weeks ago. The work sheet stated slide stops adjusted. Can't seen anything that looks like a slide stop to me.
The slide otherwises moves in and out smoothly and evenly from side to side. The horizontal position of the slide appears good with even paint lines. The slide is not centered in the opening, but neither are 2 of other 3 slides which work fine. The best I can tell the rear casters appear to be in the c-channel.
The problem is intermittent. When it occurs it seems like the chain wants to move 1 link to much with respect to the rear of the slide but is fine in the front. I did adjust the amperage on the controller to the lowest position with no changes.
It seems like either the top sprocket binds on the last chain link of movement, the controller is not turning off the motor in time (but why then only the rear chain and not both chains popping), or somehow, the moter over turns the rear sprocket by a link at not the front?
Any body have a similar problem. Any other ideals.
Thanks
