What, if anything, should I do about this jack?

[saganaga]

Picked up a free jack on Friday - it is free because it loses pressure overnight.

I tested it, and with no weight on it, it did go down by about an inch overnight. No fluid loss that I can see.

Debating if I just want to flush out the old hydraulic fluid, put in some new, and see if that fixes the issue. Or just put a jack stand underneath it while in use for the long term.

Any ideas or suggestions?

It looks like it has a locking bar that holds the jack mechanically. It is a different design to mine but my one has a mechanical lock that stops it from going down unless released and clipped out of the way.

It does have a locking bar. I checked, and it appears to hold my weight, but I do not weigh as much as a Goldwing yet (if this quarantine goes on another few months, I might!)

Is it normal just to rely on the locking bar?

I would say yes,but if you can find the specs on the internet,make sure its rated for a wings weight

I think the locking bar is suppose to be the main part that holds the weight. The hydro gets it there, then lower it to lock in. The hydro does help to hold some weight but it shouldn’t be trusted on its own, just like a car jack.

The jack is not intended to hold weight for periods of time. That is why they put a mechanical stop on the lift. This saves the jack from losing it's power to lift.

The primary reason hydraulic lifts fail is the O-rings crack or dry out letting air in.

Not always. The valve that you turn to let it down gets dirty and the O-rings leak by letting air in.

Mine normally creeps down as I nearly always have to jack it up before I can release the locking bar to lower the jack. :yes:
