HWH leak

I have a leak in the fitting above my right front jack. It is inacessable. I can see it with a mirror and a flashlight but can't get a wrench on it - need 3 hands. It is such a small opening.
I called HWH but they never got back to me. The coach builder suggested dropping the jack and tightening the leaking fitting. Do I need to remove the 4 bolts on the frame as well as the 2 on the lower jack?
Any suggestions?
Also, what size it the fitting (wrench size)?

I tried our only RV shop and they didn't know what to do. After 1 hour and $139.00 they told me I had a leak. Charged $10.00 for shop supplies - 2 pieces of paper towel.

Thanks.

Can you get to it with the tire turned all the way one direction?

Our HWH jacks have a "T" fitting on the top. Hose to one side, cap on the other. Also a wire connection for the sensor on the jack.

We had a leak before. I had the coach up on the jacks and could see fluid. Went to put it down and blew out the "T". It actually split apart above the jack. Dropped about 8" instantly.

Another reason NOT to get under your RV when it is on the jacks.

Drive the front tires up on something to raise the front end for working room if needed.

I think 9/16" or 5/8" or 3/4" wrench to get the hose off. Unplug the sensor wire.

Take the springs and shoe off the bottom.

2 bolts at the bottom of the jack bracket hold the jack to the bracket. Take them out (plates come off) and the jack will slide down.

It is heavy and long.

Should be able to take it somewhere and get it checked out, if needed.

The "T" is a standard fitting. You can get it at the hardware store. Teflon tape the threads.

I spent more time cleaning up than fixing.

Easy fix, just takes time.

Good luck!

That is what I wanted to know. I just need to get to the fittting and give it a little tightening. My motto is " if it is working - fix it till it is broke".
I read at HWH's site - not to use teflon tape.
Thanks again for the feeback.
I just need to drop it about 2 inches to get at the fitting.

I have the same leak off top of the jacks down alarm fitting.
Thought I had it fix but still leaking.
Mine is on passenger side I turn the wheel all the way to the right crawl under bumper and reach over tire remove the hydro-hose and disconnect the jack alarm wire.
Than loosen the four bolts that hold the pivot plates for cylinder bottom two you can remove but only loosen the top two its tough to get them back in with jack cylinder in place.
Once the pivot plates are loose spread apart and jack will fall down so you can work on the jack alarm fitting. If its loose just tighten if its like mine I may need to order a new fitting oil is getting by the wiring into the fitting.
HWH has them just need to call.
Once jack is off do not tilt or oil will be coming out of cylinder, the fitting has a "O" that you can replace and may stop leak mine didn't work.

I swear on my Itasca I used to own, they built the RV around the leveling jacks. I had to cut a small hole in the side of a storage compartment to get to the fitting. There was not enough room or slack to lower the jack down without undoing the hydraulic line.

Clean up was of the ground.
Pants were clean

I was sitting in the drivers seat when it dropped.

I lost about a quart of fluid went the fitting blew!

With the air bags empty mine sit so low I can't even slide under it.

download a service manual for your system. it will detail how to remove the cylinder. the fitting takes a 5/8 wrench. i have often found the fitting in the top of the jack is loose, the hose is tied too tight, and when fully extended the cylinder moves and jerks the hose. this loosens the fitting. the solution is to remove the cylinder and either tighten the tee fitting or replace it, if its damaged. this is a parker fitting. any hydraulic shop can get it for you. be sure to use teflon tape.
try email to hwh. that works better than waiting for a phone call.

you might need a crows foot wrench or a shorty 5/8 wrench to reach the hose fitting. napa or any auto parts house has these. i carry a lot of odd wrenchs to get in difficult areas, created by rv manufacturers.

Where do you download the manual that shows how to remove the jack etc. I have looked all through the manuals on WHW site without sucess. This is Tuesday and I am still waiting for a call back from Friday - I called yesterday (monday) and was told they were stll calling back fridays calls - poor service.
I was trying to find out that a 5/8 wrench was needed Now to find out how to drop the jack.
Thanks.
