RVA Leveling system bleeding off
I Have manual RVA JII system, all 3 of my jacks will bleed off and raise up a couple inches after a few day of sitting. This is on a 1999 Safari. Trying to figure out if i should replace just the retract valve stems or both the retract and extend valve stems or the whole valves themselves.

Maybe if you can, just take them apart and see if some seals need changing. I don't know where you will get parts though.

I would start by checking that the "manual" retract valves are fully closed (all tight).
I have the manual on that system but it's too large to attach here. PM me if you want it.
if nothing else works, I would change the Extend valve. but there are three valves, and i think it would be unlikely that all three are leaking at the sametime.

You can disassemble the suspect valve and clean it, which may solve the problem. Or, they also sell replacement valves at over $100 each. However, a replacement valve finally solved my "Leak-down" problem. RVA Jacks

Mine is all 3 jacks. I may yank the retract and extend valves, drop in some new o rings, may do a fluid exchange as well cause i am sure the previous owner never did and it is a 1999. See what that does.

"bowhunter72"....I had the same system on my 2005 Diplomat. The owner of RVA is very helpful. I would do as you plan. I was told that one of the issues can be dirty fluid, getting into the valve. The valve is a very pointed needle valve that can be damaged if cranked on too much.

I had read online some where, may have been the RVA manual, that the fluid should be changed every couple years. I know when i worked as a mechanic for the school bus compnay we changed the Power steering fluid every 2 years.

Does anyone know the type of fluid recommended for these RVA jacks, or the suggested changing procedure?

The RVA manual says to use Dexron III (Automatic transmission Fluid). There is no change interval listed. I don't think this fluid needs to be changed, like the power steering example, because it is not subject to the same frequency of use.

Good call, did not see that it was trans fluid. According to the troubleshooting guide on the RVA website, it is the retract valves. I will pull all 3 and replace them.

How do you get to the RVA website? rvajacks.com doesn't seem to be working.

RVA leveling jacks
RVA went out of business a short time ago and their web site is down. You may be able to get the parts you need from Northwest rv supply 541-746-9092.
