Living/dinning area slide failed

[rarebear.nm]

Living/dinning area slide was not extending correctly in our 2007 30RSO with HWH slides. The forward side would move, but the rear end would not move at all. There is a square drive shaft between the front and rear slide support arms. This keeps both ends moving at the same speed and distance. At each end of this square shaft is a round shaft that connects to a pinion gear that drives a rack gear mounted on the support arm. A sheer pin (bolt) attaches the round shaft to the square shaft. In our case the rear sheer pin had broken. Replaced that and all was good.

The pins ( bolts ) usually let go as a result of binding of the slide , time to lube the slide seals, mechanism and polish the slide walls for ease of operation.

I had just lubed the slide mechanisms a week ago. Slide seals are being replaced in three weeks.

Just a slight warning: Don’t replace your sheer pin with a higher strength metallurgy like stainless steel. The sheer pen is there for a purpose; that purpose being to prevent damage to the mechanism when the slide is in a bind.

Very good point Don! Kinda like when someone puts in a larger fuse to remedy fuse-blowing!!! Yikes.
