Hydraulic fluid leak

Help ó Need some advice on how to fix what appears to be a slow Hydraulic fluid leak in the fitting right above the VANSCO in the battery compartment. Donít want to strip the threads by over tightening. Thanks!

Hi there,
So first and foremost place something over the Vansco module to protect it from the oil. These are expensive and difficult to get.
Second confirm it is the thread leaking and not the hose end going into the swedged connector.
If it is really the thread then a very careful re-tightening might get you healed back up. Keep track of your wrench position and just nudge it letís say from 12 oíclock to 1 oíclock.
Good luck
Joerg

Hydraulic fittings rarely if ever leak. Im guessing you have a bad hose. But to confirm using 2 wrenches place one on the hex of the fitting the hose is screwed into. Holding that place the second wrench on the hose end hex and tighten. Unless your heculese your not strong enough to strip the threads.

What Alpine 06 said...a small tightening of the nut/threads may help--for awhile anyway.... but experience among owners suggests that its the hose connection/ swage ....only real option is to replace the entire hose back to the pump manifold.....
PS--its a small hose connection, agree its hard to strip the threads but you can deform the flare--then it will really leak--so be careful

Hydraulic fluid leak

I had the same issue last year and it was was not the screwed on connection! I took it apart cleaned it put it back together, still leaked. They tried to put on a new connector but the rubber around the hose fell apart. They ended up replacing the hose back to the pump. To do it over I would have replaced it myself! $$$$

I did one of the hoses for the large slide out. It took a Parker outfit 20min to replicate the hose for $59 in Lexington KY. Also it was less messy than I expected I think the longest part was driving to the shop ... lol.

Be advised, the easiest way to replace the hose is to just abandon the OEM hose in place and reroute the new hose along the frame....might not hurt to procure a new hose that is a tad longer to address and potential length issues with the new route.....

It looks the the culprit hose is the bedroom vanity slide retract hose that runs from the HWH pump up front to a metering valve and tee fiting that I can just make out in your pictures. There is a history of leaks in the street side broom vanity slides (34' & 36' models) over the radiator stack and the syncro cylinder over your Vansco so you may want to check for leaks over your radiator stack too.

If you have to replace the hose then the HWH partnumber for both the extend and retract hoses that originate at the pump manifold is RAP2464 1/4" ID x 324" long.

Hey Carter, interesting catch--it does look like the hose is connected to the vanity slide on the passenger side …. but Max says its a 36--so is the equalizer for the wardrobe slide on the 36 on the passenger side/bat compartment or does the 36 also have a vanity slide? Also note that the metering valve for the vanity on my 2003 40ft is on the pump end of the hose. WRV model variations never fail to amaze....[me]

Maybe calling it a vanity slide is confusing. My slide has the bath vanity and a closet on it but now that I think about it the Ď34 model only has the closet on the slide. WRV variations, no kidding!

Sorry, I am getting way off topic here but to clarify, is your street-side [passenger?][vs curbside?] slide a vanity or a wardrobe slide? If vanity, do you have a wardrobe closet somewhere? Again, my 40ft MDTS has a different slide config. from yours.

Only one slide In bedroom. It is on streetside. It has bath vanity on it and it has closet (4 drawers + 3 mirror doors) on it. Bed is north-south.

All, thanks for the info. Very informative and I appreciate the specific countermeasures. I spent some time today attempting to tighten the nut with only minimal success. Slight movement, not even a quarter turn. Re the slide in the bedroom, it is a closet with mirror wardrobe doors that is on the drivers side of the coach. Both slides in my coach are on the drivers side. Btw, the bed runs north and south on our coach. Cheers!
