hydraulic jacks

[faye]

I have a 2004 national seabreeze lx, recently purchased, lt front jack will not fully retract, i can get out and manually push it in...any idea what is causing this? Does the hydraulic fluid to operate the jacks in this motorhome come from the transmission or is there a separate reservior for the jacks?????next, when you are parked at home do you keep the jacks down or up??????

faye, it sounds like you have a spring return style leveling jack. It could be that the spring is weak, the piston needs cleaning, the jack is bad or the hose feeding it has a kink in it. If you are going to be running the refrigerator the coach needs to be level. Otherwise, it is a personal preference as to putting jacks down or not.

RV Wizard pretty much covered everything. To be more specific, per the manufacturer's recommendation, clean and lube the exposed piston/s with silicon spray. Your jacks have a separate reservoir which holds hydraulic fluid. The fluid is the same as your automatic transmission. It could be the spring is weak on the jack, but chances are a good cleaning as RV Wizard mentioned might do the trick.

Some of the Power Gear jacks have grease fittings at the top of the jack.
