Solenoid locations

[Dave&Kacy]

A leaking hydraulic line has started an adventure in our 2003 unit. While investigating a leak at the main slide, we noticed another leak at the vanity side slide. Upon further investigation of how the hydraulic lines were run through the coach, we have located three other leaking hoses, and have only gotten part way through the coach.

I have researched the forum and noted that in 2002 and 2003 HWH had a rash of bad hoses, and now I can attest to that. What I cannot find is a diagram od the locations of the solenoids and rams for each of the slides. I have located the solenoids for the main slide and the bedroom vanity slide, and the rams for the bedroom vanity slide. But I'm still trying to locate the solenoid for the bedside slide and the rams for the bedside and the main slide. Also, has anyone found out how to access these other rams?

We contacted HWH to acquire a die (#4540-30200) to crimp new hoses, but they would not sell one to our RV service center. So I have decided to replace all of the 1/8" hoses with new Parker Hannifil hoses and fittings, as I can get them done quickly and cheaper than HWH.

There is a wealth of info on this site concerning HWH hose replacement. In general terms, all of the controlling HWH solenoids are situated on the HWH pump in the compartment just behind the passenger side front wheel [there are also two "equalizer tubes" for the main and vanity slides]. The rams for the main slide are inside the large metal tubes that extend to support the slide--the hose connections are visible in the basement on the passenger side. On the 40ft, the bed slide is a major challenge. The hoses enter thru the floor, above the transmission/differential. The hose connectors for the bed slide are buried in the ram assembly under the bed--this is a major effort to take apart and redo. Once they leave the pump compartment, many of the hoses follow the frame to the rear of the coach--getting in between the frame and the fuel and water tanks to remove the old hoses/run new ones is not easy.

After a slide hose parted, I had some hyd. hoses replace last year by a RV ser. co. in Vancouver. They explained that swedged fittings are better than crimped and some hose material is made for crimped and some for swedging. WRV had opted for less expensive hoses. That was one fellows opinion.
