Had a harbor lawn mower jack , it would only lift mower until weight hit jack. Bled jack four times still same . Did exactly what your you tube video showed. Used Wd40 to flush and jack now works great with ATF. THANK YOU MUCH
Great video without the hype. Just pain, simple useful information and demo. Well done.
Thank you very much for appreciating the video!
just found a great use for some extra power steering oil and ATF that have been sitting on the shelf for a long time. Thanks for the vid.
I just fixed an old Jack I picked up from a thrift store doing this. Nice video, I really enjoy fixing up old tools and I've now got a new skill to do this.
Thanks! Useful activity, I also fix old things
So glad I came across your video, I bought a new 20 ton jack a few months ago because I couldn't figure out where my other one was leaking from, well it has sat there gathering dust because I had lost the info of how to set up the new one, and as it is coming up to my busiest time making jewellery I was getting very despondent, now at least I know how to fill up and release air in the new one, pretty sure the connecting will be a doddle haha. Thanks again.
Thanks a lot! Good luck with your work!
Good advice. I will change my oil after buying the correct oil to refill. Well done.
Hello , please what kind of flushing fluid do you use for your hydraulic jack ?
Thanks bro for another meaningful lessons for important use..
Thanks for the comment!
Great video . I never realized how important it is to do this. It's like night and day after I followed your method . My jack performs much better now . THANK YOU.
Excellent , no nonsense video as well , great job there too.
I saw , in another comment , you used gasoline and you said kerosene will also work.
Would paint thinner work as an alternative for future reference ?
Never mind that question in my comment . After reading a few more comments , I now have my answer.
Thanks again , GREAT video.
I did read that ATF oil is no good for the seals, and that SAE10W is the way to go, what do you think?
Very informative; thanks.
Thank you! Subscribed.
Very helpful. Now that I have lubed with some good oil, I can jack my piston to full extension in only a few strokes.
Thank you for this. Perfect. Fixed a jack I tipped over and spilled all the oil out. Thing works like new again.
See tic
Very good tutorial. Nice job sir.
Really fantastic buddy
what is a good oil to use?? should you use jack oil ...what about the special hydralic oil i add to my impact wrench and other air tools to keep them work...so i see you say power steering fluid in comments is good also...thanks for sharing
I just bought one of this China made abundant on the market and the instructions ask for
just SAE30 oil. After that i did replace the oil using jack oil and installing a brass plug on
the oil port because the factory rubber plug on this cheap jacks harden and eventually leak.
Great video, but what was the fluid you used to flush it with?
Thanks a lot! I used kerosene, but you can use gasoline or solvent
@@helpfromthegarage1677 Thanks! I needed this, I can now maintain the new bottle jack my father has and restore the old one which was discarded with the aid of your next video; "How to open a hydraulic jack"!!
In another post they said not to ever lay a bottle jack on its side. I store mine in it’s case like this in my trunk and it’s definitely on it’s side. Is that a bad thing for it?? Also it’s only been used once or twice..should I change the oil in this case?? Is it necessary?(because of non use) Thank you in advance!
You can lay it on its side or even upside down, but it won't work in an upside down position. It may work in a horizontal position but you won't be able to extend the ram fully and it really depends on which side you gonna lay it. You don't have to change the oil for decades if you don't use your jack regularly, but I'd use it once a year or so (without load) to put an oil film on the walls of the cylinder and the pump to prevent it from rusting.
it was helpful thanks
Very helpful this video I appreciate this video
Thanks a lot!
Great video!
Is it ok if I fill my trolley jack with it stood upright like your video instead of it horizontal? Thanks
I'll answer my own question.
My SGS jack's instructions say to fill, turn J vertical with handle down and fill to plug level (as u would a bottle J). This emptied some oil then the J wouldn't raise very high so I put it horizontal to check and the piston had no oil covering the top. I filled just above the Post and all's well again.
So NO, fill to top of piston on you floor/trolley jack in the horizontal position! In my case anyway.
Beautiful..... Very helpful.... Thank you
Great job, on the jack and on video. Can l use type f (old ford trans fluid) to refill my 8 ton jack? Thanks and God bless.
Thanks a lot! I think you can. But it is best then to completely replace the fluid.
I'm reading the instructions to my new bottle jack that are lacking in description, but does say to only use hydraulic jack oil, and NOT to use brake fluid, turbine fluid, transmission fluid, motor oil, or glycerin.
This was from TCE31001 jack manual
Thanks..I was wondering.
great thanks!
thank you ,video done very well,
Thank you very much for your rating!
Thank you for showing us this……..
Very nice video
Hi! Great video man . Do you how to bleed the a floor jack correctly ?
Hello! Thanks a lot! I have a video about it
@@helpfromthegarage1677 i've got a new jack and I was trying to get info to repair the old one . Almost any , if not all manuals says to not use brake fluid , motor oil , transmission fluid, glycerine , alcohol , etc . I've bought 1L of liqui moly hydraulic oil hlp 46 , wich is more than enough for the job
THANKS!
Thanks
Thanks...
Very helpful. what is flushing fluid ?
gasoline, kerosene, solvent
What do you use for the flushing fluid?
May be Kerosene
Thank you very much..
You'd for me understand about to it !
I’m removing my 2.9 engine on my 2007 Colorado as valves and seats are pitted had low compression
Leek down test doesn’t seem to be getting by the rings
Thanks a lot I have a question, Can I use steering oil in a 4 ton hydraulic jack?
From the steering gear or from the power steering?
The power steering
Yes. You can use
Very useful vid. Thanks

It says in the jack manuals to only use jack hydraulic oil, not brake fluid nor any other type.
Nice
What was used as the cleaning fluid?
I used kerosene. But you can also use gasoline or solvent
Thank you. I am still confused why my bottle jack wont lift load more than 150kgs after service. Is it the air trapped inside?
There may be air, or the valves do not hold pressure. This also happens when the bypass valve bleeds.
Turned out air was still leaking from around the bottle neck. So a few more turns applied to tighten the upper part. Really had to use some kind of strong clamp tool to really hold the bottom of the bottle jack.
Is the jack lifting the load now?
@@helpfromthegarage1677 yep, and it seems to hold the load much stronger than before. The jack used to after several days slightly go down till it stopped on the support stand.
Can I use 20-50 oil? I saw some use 15-40 oil as fluid for the jack. Thx
Only hydraulic or ATF 2 fluid. Jack oil preferably.
The most common jacks on the market made in China come with SAE 30 oil from factory.
I bought 2 of them and replaced the oil with hydraulic jack oil. I also replaced the rubber plug with 1/8 brass plug because they do leak from the rubber factory plug..
@@horaciocastillo1435 I accidentally opened the bottom plug and drained some oil. Can I add hydraulic fluid on top of the remaining oil?
dtsi engine oil pathi video podunka bro please
Can you use transmission oil in the jack .
Use jack oil, available at any auto parts store. It is formulated to stand high pressure.
We can use break oil...
Perfect title; you saw me coming :-)
I had one low on oil, and it must have sucked in more air during the big TX freeze, to the point where it wouldn't retract after all that air warmed up again.
I did not understand the question
Super 💐
Thx
Would it harm anything to rub this oil on the post to keep it from rusting?
You do not need to do this, dirt will get on the oil surface, causing wear on the stem seals.
For rust protection nothing better than WD40 wich is a product made for that purpose
WATER DISPERSANT 40 or boeshield from Boeing.Spray and rub the surface with a clean
rag. I buy the WD4o in galons, it is a lot cheaper. Cheers my friend.
@@horaciocastillo1435 Thanks for the insights Horacio
Which oil use in jack
Hydraulic oil such as ATF, semi-synthetic or synthetic engine oil.
@@helpfromthegarage1677 Thanks
is the fill plug needed for the jack to work?
please clarify the question
If the fill plug isn’t in the oil will leak out and air will get inside the hydraulic along with dirt etc.
@@miwarrior060709 The air getting inside the reservoir is not a problem actually, there should be some free space (air) anyway.
The oil level should not be higher than the fill hole. A seal there is not required if you keep your jack standing vertical.
What is the flushing fluid ?
kerosene or carburetor cleaner
👍👌👏👏👏
Will a dot3 brake fluid works?
I do not recommend using brake fluid. You can use motor oil, synthetic or semi-synthetic.
brake fluid can be aggressive on plastic & paint.
I used compressor oil. Works as well. Dono bout motor oil it may deteriorate the seals.
Good job!
WHAT DID YOU USE TO FLUSH THE JACK?
That’s my question too…?
I washed with kerosene, but you can use gasoline or solvent
How much oil used?
The amount of oil depends on the size of the jack. Fill up to the level of the filler neck.
Thank you. I am greatful.
Can i use brake fluid? How do i know the oil level?
You fill it up until it starts to drip, in standing position, of course.
Hi i have a problem working up but not falling down :/ nie to Fix it
👍👍👍

What is flushing fluid
kerocine or carboretor cleanor
I wonder, although there appears to be 2 differant kinds of removing air from jack(1 bleeding, 2 the actual cylinder), but despite all that - while many if not all bottle jackninstructions say don’t over fill, does not the very fact that we’re supposed to only fill to lower edge of that circle imply that there’s SUPOSSED to be air in there?🤔
can use motorcycle fork oil?
Yup as well as atf, power steering, hydraulic oil or Jack oil.
@@rayc1503 can l use type f trans. Fluid? Thanks
@@olblu8746 I shouldn't see why not. As long as it's none hydroscopic. It's an ATF based oil so should be ok.
Where did you buy the syringe?
Bought mine at a pharmacy store,
What did you use as a flush as a flushing fluid?
gasoline I'm guessing. ah, he says "kerosene or carburetor cleaner"
Isme kon sa oil dena hai guru ji
industrial oil, atf, engine oil
sure wish I watched this video 4 jacks ago
Me too, l gave a 20 ton jack away cause it was lifting too slow. Later l found out all it needed was a little jack oil. It had been sitting for several years on the shelf.
can we use diesel as flushing fluid ??
You can, but this is not the best way
Think twice before you follow this video instruction! I followed this video and ruined my 3 ton bottle jack. It was almost new but the oil was half drained accidentally. I followed this instruction and used paint thinner to rinse the old residue. However, I immediately noticed that the lever started sticking as though the inner seals were dissolved by the thinner (or the solvent). If you read the comment section, the publisher recommends to use kerosene or any type of solvent for flushing. But beware as some of these chemicals may destroy your jack seals to an unrepairable ending as what happened to me. It also destroyed the paint of my jack not to mention the least.
I would advise you to choose another instruction and make a wise decision in what to use to flush your jack! I followed the instruction till the end and even released the air in the jack. But my jack won’t hold up the weight and won’t jack up as fast as it used to. In other words, it is useless piece of metal now. 😥 😩 😡
How much
Upton the brim of the filler hole, let a little seep out.
Guys use a good quality jack oil ATF can destroy your seals. The extra dollar or 2 to put the right oil in is worth it.
This saved me from buying a new jack.
What kind of oil you use to flushing?
I already have the answer from your previous chat 👍
Thank you!
Just came after splashing my left eye with the oil from the jack
😄🖐️💛🙏👍
💚💜🧡💙💗
thank you for the much needed silence, I'm sure you use hydraulic oil for the big pumps.
Thanks a lot! Yes, that is right

Like many YT videos they are so bad to almost be dangerous! Jacks can have different seal material in them so how do you know which flushing agent to use? You don't so you have to find out by talking to a pro not what rank amateurs on YT tell you!
What do you mean?
thats right... you need to change your carjack oil every 75 years to ensure a proper fonctionnement...
Yes...my bottle jack will outlive ME!
-- BR
Oil is changed when problems with the jack begin
You talk too much
What is the flushing fluid?
We used kerosene. You can also use a carburetor cleaner
Cheapest best flushing is paint thinner for oil paint also called mineral spirits.
do not use carburetor cleaner, real bad for rubber seals. cheers
👍
What is the flushing fluid?
Gasoline, kerosene. You can also use a carburetor cleaner
