1999-2000 HWH SLIDE HYDRAULIC HOSE FAILURE

If you own a coach built in 1999 or 2000 with a slide room, it would be wise to check the hydraulic lines. Especially the 2 interior ones that run to the upper locking pins. These lines run from the lower front locking pin, inboard to the center chase, then forward to the front cross member, then outboard along the cross member, and pass through the floor below the left driver console. From there they go up the wooden chase into the overhead storage above the pilots seat. Then they go to the rear and connect to the upper front locking pin, and on to the upper rear locking pin. From the power unit, they're daisy chained: LR-LF-UF-RF. One of ours failed, in the storage cabinet above the pilots seat, due to an error in the installation. It made a BIG mess. see New to us 2000 U320 - Page 3 Post #63

EDIT: Corrected the routing of the hydraulic lines for the slide locks.

With that stuff "a little goes a long way"

Had the pin leak in mexico.. Just a seal but made a little mess.. Not fun..

Sounds like something was rubbing and not tied down and rubbed a hole possibly?

Good luck.. Hope it is cleanable.

Thanks for posting the timely "Heads Up" warning.  ^.^d

If you take any more photos of the damage, or the clean-up, or your repair, please post them here for the edification of all.

David, If you look at the last picture in the linked post. you'll see what I'm talking about "error in the installation" This wasn't a problem with the quality of the HWH lines, or rubbing. This was caused by an entirely avoidable tight radius in the lines. Fact of the matter is, I noticed this last fall when I replaced the factory solar stub-out leads with cables for my 1.2M satellite rig. (No leaks at that time, though) I had planned on replacing both lines this summer, during our off-time. Soooo... some of the blame must fall on me for not getting after it sooner.  :-[  That doesn't excuse this passing muster at the factory.
I do plan to replace the seals in the upper locks while oil is everywhere but where it should be ;)

As usual, the repair was a last minute before we leave, deal. Cleanup was a PITA royale, but everything survived without damage. I used oil dry, Tide with water, and several rolls of blue towels. While we were at Xtreme, last Dec, Rance mentioned that he had never seen a slide room built like ours. He said the outside face appears to be vacuum bonded to the frame and the frame has diagonal braces. I assumed they were all like that, but a tour of the stock at MOT turned-up no others. Upon closer inspection, the shell appears built up from 5 pieces, all bonded to the frame, and each other. The reason I mention this is because it seems it's an oddball and the hydraulic line issue may be limited to this unit? Regardless, pic attached of proper line routing.
