REFILLING long ram hydraulic bottle jack with fluid (making flexible funnel)

Refilling a hydraulic jack or cylinder is pretty straightforward if you’ve got the right tool. I modified a funnel with a piece of silicone tubing. It took about 10 minutes but everything worked just fine after we were done.

I tried this way, worked on my 18” hydraulic engine lift. Thanks

really good video thanks!!

[@antonios4926]

Thanks for the video. I have a Genie scissor lift. What type of hydronic fluid do I use? I am getting conflicting advice.

I had not used my hoist for a while and it decided not to go up any distance. I figured that as I pumped the jack a vacuum was being formed inside the reservoir because of the rubber bung. I removed the bung and no problem - I think there should be a breather on the reservoir instead of the bung.

Thank you brother

[@frankgalassi7821]

Can you fill it while the jack is all the way extended out?

[@WiseRuler]

So I've added oil to mine but it still won't lift a load. It pumps and lifts without boom attached but not with. I've tried bleeding air but maybe I did it wrong or it could be bad seals inside? I got it without oil plug in it. Maybe debris or junk got in it?

[@Dev_Everything]

how do you purge the air out of one? I heard that you must turn the valve to the OPEN position and then pump the jack a bunch of times and this will clear the air

[@dgaz3057]

yes, then you are supposed to leave the lower valve open and then release pressure out of the rubber plug on top, insert a small screwdriver on one side of the upper rubber plug, and pry it enough to allow air to escape without removing it. Close the bottom valve and then pump away.

[@mule666]

Everybody thinks they know it all😂 so no bleeding air out ?

[@dannilaser16]

Do you have to have the lowering valve open when you fill the oil, or in the closed position?

[@livefree6878]

As I recall the valve can be open or closed during filling.

nice thank you

[@spencerdasilva]

Thank you

[@dgaz3057]

bleed process?

[@hipairbrush1053]

Would it harm anything to rub this oil on the post to keep it from rusting?

[@tortron]

I do this for one kept outside. The only issue can be if dirt sticks to it, it will. Shorten the life of the seal. I just wipe it down before use

[@user-bq3hc3jg2y]

can anyone answer this ( if i was to weld shut the fill hole on a long ram jack like the one in this video would it effect its functionality? )

[@dgaz3057]

yes thats how you bleed it. If you lost the rubber plug, I would tap it and find a small bolt to plug it.

👍👍

[@Richard-kz2om]

What is the position of jack???

[@BOOSTJUNKY]

Down

[@patelpower3579]

Oil grade ???

[@billjones5178]

Too about a pint of hydraulic oil.

[@dansteving5915]

Nail clippers don't open that wide.
