Frank,
Thickness of the delrin or metal strip (whichever you decide to use) should be determined by the amount of sag you want to correct. I used the paint borders from the fixed wall to the slide to determine thickness needed. Not sure why you would need to fill in depression made by roller in bottom of slide as the delrin will cover it, unless you are concerned about moisture ingression from high humidity environments. I used 2 different thickness strips on my 01 Contessa front slide to get it level (paint borders aligned).

Frank,

Like Steve I think you tailor the thickness to the offset in the paint striping difference. As the Delrin material gets thicker there may be some clearance issues with the slide seal, not sure. I like the Delrin approach and over several years of use I had no issues with it at all.

It appeared to me that as time went on the stripe offset started to increase a small amount again meaning there probably was some continued sag in the roller support structure but not enough to warrant going thicker. The shim shingles would have been my adjustment method at the outer end of the Delrin strip if it became an issue. It only has to "park" the slide height where you want it at the full in slide position. I used a 45 degree slope along the long edge of the Delrin (table saw cut) and then rounded the point where the 45 cut ended using a sander. The more shallow the taper the better the slide seal will conform and follow the Delrin edge. If my saw could have made a shallower cut I would have gone to 30 degrees or so. Delrin is a perfect material for this given it can be milled, won't rust, very smooth and easy on the seals as it travels against them.

To sort this out you could get a base measurement and then gently jack up the slide, measure to a reference point like the trim molding below, and see if raising it a half inch still provides the necessary clearances and the seals have reasonable contact. If not go to 3/8ths inch. Things should fit OK given you are basically going back to what the original fit was. It does not have to be perfect, just the best compromise.

Frank as far as adding bondo, I think I would just use a bed of silicone to fill the gap under the Delrin and then let it cure before putting the weight of the slide on the repair. Because the Delrin is a bit wider then the roller (you could add a bit more width if need be in the Delrin) it should go beyond the depression width wise. (Don't forget to allow for the tapered edge in the Delrin when you come up with the appropriate width of your Delrin sheet repair stock)

As far as the front slide, that is very heavy, I would probably consider a thin metal plate there if it was bad enough to require a repair. In that case I think you are preventing a wear point and not trying to build up thick material for a roller structure sag issue. Hope this helps.

Later Ed

Steve, Ed, thanks for reply. I have taken some measurements on both the front and rear roller sag of bedroom slide and decided to try 1/2" thick delrin on the rear, which has sunk approximately 1/2" and 1/4" on the front, as both sides of slide rollers have worn into plywood. I am hoping to get tapered screws into front piece as thickness will not accommodate a standard screw head. Again, thanks for input and will inform about outcome. Frank.

Frank,
Consider adding a 1/16" to the thickness of the delrin runners. With the 2 coaches I've done, the offset of the paint edges plus 1/16" ensures the paint edges will line up when completed. See the before/after pictures in the first post in this thread. The floor apparently sags somewhat with the weight of the slide.

Hello Steve,
Our 2000 Marquis Jasper has a 3/8 sag at the rear of the front slide. We jacked it up and added a 3/8 aluminum plate. When we activated the slide the gear that engages the track became disengaged allowing the slide to rack. We had to remove the plate in order to reengage the alignment gear. We could not figure out how to adjust the pillow block to support the mechanism with the gear properly engaged. Any suggestions?

Richard,
The rear of the front slide rests on 2 rollers, one near the outboard edge of the slide and the other inboard near the inboard edge of the cabinets that jut out toward the reefer. If the installed plate isn't long enough to engage both rollers, the slide will rack when bringing it in the first time. (I know from experience / kind of exciting to see it  ;D). I had to pull out my first plate and reinstall a longer one that engaged both rolllers. Measure to get the exact length. I added a bit to ensure the front roller would never jump off it. (Memory is foggy  but I think it was around 22" or so).

Steve,
If I understand correctly you believe the alignment gear disengaged because the short plate allowed the inner part of the slide to descend a bit when it passed the inner roller, thereby tipping the outer edge up. Is that correct?

Richard,
Yes. Having the plate contact both rollers will level out the slide, inboard to outboard and it should then re-engage (at least mine did).

Hello all, have completed delrin runners on front and back rollers of bedroom slide. The rear runner ended up being 3/8" thick, 5" wide, and 19.5" long. The front runner ended up being 3/16" thick, 5.75" wide, and 19.5" long. Screw holes were drilled with Ed's measurements. The extra width on the front runner was required as to hit the aluminum framing with the screws on edge of slide. Paint lines on front runner now match perfectly, rear runner is about 1/16" high, to accommodate future sag, which was suggested by Ed in previous posts. Also as Ed suggested, cut long edges of runners at a 30 degree angle to accommodate seal over runners. All in all, project turned out very well and am very happy with results. Thanks to all who helped with project!!! Frank.

So, question.......Where do I install this shim??? i can't seem to find out where it says to install it!  I have the same slide out sag issue!,


Ah, I found it, i was on the wrong page. My issue is on the front curb slide out, same issue but i don't think the rollers are even in there, and i don't think this post pertains to that.

Well its pushed to the front now!
