Powergear jack unit leaking???

Has anyone ever have a power gear hydraulic jack pump unit leak when not running? I recently poured a concrete pad for my 99 fleetwood southwind and noticed the leak with the jacks retracted. I crawled under and noticed the the reservoir seems wet. I cleaned it and tighten the float switch plastic nut. It was dry for a couple days then noticed the leak again. Had my wife run jacks while i watched for leaks. All hoses and fittings seem to be dry. Looks to me as if it is leaking out of where the reservoir meets the metal pump unit. It is a vertical setup...jacks work fine and hold pressure fine. Any ideas??????

You are going to have to thoroughly clean the entire area, dry and inspect for leak ater several hour intervals to find the point of the leak. You could have a bad gasket between the pump and reservoir or it could be between pump motor and pump. Once you find the oil leak you can find out if it is an easy or more complex repair. Good luck and keep us posted.

Believe you'll find the "tank" is welded to the pump. This was a big discussion 3-4 years ago when the unsupported tank started cracking the weld. Many of us installed a "cross member" under the tank for support.
The repair required removal of the unit and rewelding.
On iRV2 google "powergear pump leaking"
Hopefully your leak is something like Mike described and easier to fix but do consider the "brace".

On mine the reservoir itself had a hole rubbed in it by the MH frame. The mounting bracket does not put enough space between the res. and the frame and vibration make a hole. It was a simple fix and easy to do. You can buy a new reservoir or do like I did and weld up the hole and add more metal to it. Either way you need to remove the reservoir (not welded) and space out the unit from the frame with washers.

Yours is maybe different than mine but....

I agree with H Miller. There have been a good many folks that had the weld to break due to the vibration and lack of support. IF, this is the problem I think some had it welded and some had to replace it. Seems I remember someone saying they actually used JB Weld. Regardless, if it has no support, then engineer something so the repair does not have the same fate.
