My coach has one large slide with the couch and kitchen in it. After 21 years it looks like it needs some minor adjustment. When its retracted, the seals are compressed at the bottom more than they are at the top. In other words, the bottom of the slide hits the side of the coach before the top does. Also, the seal on the front is compressed much tighter than the seal at the rear of the slide. The paint lines line up in the front, but are slightly out of line in the back, I'd say no more than 1/4" low.
To summarize, the slide appears to tilt out slightly at the top, the front of the slide retracts more than the rear and the rear is slightly lower than the front.
The slide is generally in good shape. Here are a couple pictures of the bottom.
I'm thinking there must be some type of procedure, or order, in which these adjustments should be made? My thought is the slide should be square to the coach before I adjust the rollers under the counter and couch for height or the limits of in and out travel?
I found a thread where Walt2131 explained how to shim the hydraulic ram to adjust it so the top and bottom of the slide contact the side of the coach at the same time, but I want to make sure I fully understand the procedure. I'm thinking I need to shim behind the top bolt to make the top of the slide align with the bottom? The steps appear to be to support the slide with blocking of some type. I think I might need to actually lift the slide on the outside so I can take the load off of that bolt so I can shim behind it. Then its trial and error until I get it aligned properly?
Adjusting the rollers seems straight forward, disengage the locking tabs, back off the hut until the roller is free, then tighten the nut until the roller firmly engages the floor. I'm thinking I then check the alignment on the outside of the coach to make sure the front and back of the slide are aligned properly?
Do these two bolts adjust the in and out limit of travel?
This looks like its the "in" limit adjustment.
Is this the out extension adjustment?
I'd appreciate advice from anyone who has adjusted their slides.
