Ace schwintek slide design

Just spent 11 hours fixing my slide on my Ace 30.2(full wall slide). I had a rv repair shop fix the front rails because it had skipped a tooth or 2. He had it for almost 3 months. He said the back rails where fine and it did work. Went camping 1 time and when I got home I pushed the slide out and about 3/4 of the way out it popped and skipped a tooth. Rail was destroyed. Ordered new back rails and bearing block ( not sure why they call them bearing blocks because there is no bearings in it). Luckily my dad and brother are both machinest we ended up putting a brass bearing in the lower bearing block works great. [ATTACHClick image for larger version

You can't have a hexagon shaft in a round hole with nothing to keep it in place. We turned down the shaft so it was round and it rides nice and snug in the bearing without any play. The top block is the new one I had the shop fix. I cycled the slide maybe 4 times and that is what it looks like already. He put a bandaid on the problem it was going to fail again soon. Lippert needs to do a recall on this design. The way they built it it is going to fail. If you have this slide design you should find someone with a mill and a lathe and fix it the right way. Also do this yourself it took a day to replace and repair both ends of the slide not the months it takes the rv shops. Click image for larger version

I have to replace the bearing blocks, spur gears, and track on my slide. Where did you find information on how to remove the system to make the replacements? Look like I will have to drill out rivets to remove the brackets...is that what you had to do?

You did an excellent job showing us up to this point. Would you be so kind to share the detail with everyone, so if others have the problem in the future we can refer to it. Thanks.

I don't know the year of his coach but, is this prior to the new 3Trax System?

Itís the same thing whether itís a 3trax or not. Horrible design. Since fixing mine ourselves the right way I have had no problems what so ever. I posted before that I had a shop fix one side of the slide. When I came back from a couple of camping trips the other side of the same slide failed. Upon fixing it we noticed the side that was just fixed by a shop was already showing signs of failing.

Itís not a hard project. Took about 8 hours to fix both ends. I can try and write up something but it would probably be easier to answer questions.

Also when you call Lippert and order new rails
, ask for the black ones. Makes it easier to see if itís chewing up the rails down the road.
