All,
We took a trip to St Augustine for the week. Once parked went to extend the slides. Front had no issues....the bedroom's rear slide lock developed a massive spewing leak upon activating the extend mode.. The interesting thing to note here.....absolutely no warning of impending failure, no leaks drips runs or smells....nothing! The "Blind hog finds an acorn" analogy here was I stop the extend cycle immediately. The intense urge to continue was almost unbearable but I resisted. Once back home, pulled and disassembled the rear slide lock....found the seal had come apart due to small amounts of foreign matter collecting on top of seal as its a low point in the flow of fluid. Also found out that the seal is a "Loaded U-Seal".....the same size as the shaft seal I used on the on the slide actuator (The O-ring Store, P/N UL125-0.875-125 Polyurethane U-Seal). This seal is slightly harder than the original and should be more robust but, will require the removal of the internal snap ring with a pair of articulating needle nose snap ring pliers. The seal I had used on the salon slide lock and identified in the previous picture can be installed with out removing the snap ring and works just fine.
WYIT mind set I rebuilt the bedroom's front slide pin lock as well. Since I have already rebuilt the salon's rear slide pin lock assembly I'm going after the front slide pin lock assembly next!
Given the fact this failure gave no warning I would highly recommend rebuilding these locks. Especially if you have the time and access.
Another note to add. I had tried to order the loaded U-seal and several other o-rings from McMaster Carr back in November they had six week lead time. Then in December they notified me that due to supply chain issues my order was cancelled. The O-Ring Store had them in stock and prompt shipping to boot.
