2000 Southwind Hydraulic jacks won't maintain pressure.
« on: August 12, 2018, 01:18:32 PM »
We purchased a 2000Southwind that originally required frequent replenishment of fluid but now won't hold pressure on any of the jacks. The jacks won't stabilize the unit and any movement is felt throughout the coach.

Any thoughts from others who may have experienced this situation.  These is a Power Gear 500456 hydraulic jack leveling system.

Any suggestions are appreciated.

Thank you

John

If they don't hold pressure, you probably have a hydraulic leak somewhere. If there is no fluid lost on the ground, it's draining back into the reservoir through the valve in each line.  Or possibly the pump  simply isn't producing much pressure, just enough to move the jacks down but not applying much lifting pressure. Does the coach  level up ok? 

The one you have is a pretty simple system, basically two hydraulic lines to the rear jacks and one to the front pair.  The pump pushes fluid from the reservoir into the jack rams through a valve that prevents back flow, raising each jack or jack pair.  The front pair are cross-connected so they self-level.   To lower the coach, the valve is opened (electrically) to let the fluid flow back into the reservoir and the springs on each jack pull it back up.

All four lose pressure so it sounds like I need to look at the pump. Thank you for your quick response.
