Front Right Jack Won't Come Down
 
I was going through my weekly running of the 345 (I try and run her up the highway once a week to keep things in operation through the cold months by taking most of my office to lunch in it on day a week) and thought..."boy I haven't cycled the jacks in a while" so I tried them.

Three out of four came down but not quite 90 degrees to the frame and the front pass side didn't come down at all. These all used to work this summer.

My [no experience with hydraulics] mind thought...looks like its low on fluid. But I don't even know where the resevoir is located.

Any suggestions on where to start?

I would try cussing and screaming. Might not get the jack to work but might save you from picking up the lunch tab.

ok, I apologize
 
But I do have a hair brained idea. Try a generous application of WD-40 on everything that moves or has friction.
My daughter recently had a prob with her HP printer and even the local computer repairman couldn't fix it. I sprayed a little WD-40 on both ends of the carriage and now it works fine.
I'm not being stupid on purpose, Your jacks are probably victims of extended non-use . Alternatively, you might take the RV to a local muffler shop and have them lube everything.

I believe the fluid reservoir is in a next to impossible place to get to. Pop up the dog house and look towards the rear. There should be a horizontal tube/can/tank with a cap on the top.

"Impossible to get to"
 
It appears as if Fred's been there and done that.

I found it easier to attack it from underneath. The cap isn't TOO hard to get off, but I have no idea of how you could visually check the fluid.

I just stuck my finger in (middle digit dipstick) after removing the cap, as long as there is fluid a couple of inches from the top, you should be OK.

To add fluid, you might try a good flexible hose and funnel.

I have a .doc file on recommended fluid somewhere, I'll see if I can find it.

Info - couldn't find the .doc

Steven,

The fluid in hydraulic system of the Xeppelin is red, and gives every indication of being transmission fluid.

Should I ever have to top the fluid level off, it will be with transmission fluid.

To fill it try something like this. It is also good for rear axles and all those other hard to get locations. You should be able to find a similar one at a parts store too.

i had the same problem. the drivers side. i tapped the jack housing with a brass hammer. havent had any more problems. that jack will take your breath away when you ask for a price.

thanks!
 
Thanks all! I went looking through my pile of documents again last night and sure enough I have the installation manual for the A&E jacks. (should have checked before posting)

Here is a listing of recommended fluids from the installation manual:

SAE 5W Non-detergent Motor Oil
SAE 10W Non-detergent Motor Oil
SAE 5W Light Hydraulic Oil
Type A Transmission Fluid
Type B Transmission Fluid

WARNING: Never use Brake Fluid, Hydraulic Jack Fluid or Type F Transmissions Fluid.

The procedure for checking the fluild level is:

All Jacks in the retracted position
Remove breather plug in the pump/resevoir assembly
Fluild level should be 1" from the top of the resevoir

There is also an adjustmentsand troubleshooting section that's decent. Its only 12 pages so if someone needs a copy let me know.
