THANKS A LOT!!!!! ......DAMMIT! did as you described and when I lowered the cherry picker, it blew out the fill bung drenched me and blew hydraulic oil 20 feet across the shop, drenching the shop-floor computer and a bunch of expensive electronic gear!
Wow. So the fill plug on your hoist unthreaded and flew out? Or is your fill plug just a rubber push in stopper? That is a no brainer. You know I watch a ton of videos on something before trying it myself. Perhaps in the future you could try the same thing. Or just don't mess with stuff you really have no clue about.
Same thing happened to me. Good thing was it just shot the oil all over back yard grass but my shorts got soaked & even after washing are still stained.
Same here, fluid shot across garage from the fill hole. Found another video that shows to take the whole jack out of frame, jack it up to extend piston piston fully, flip it upside down so top of piston is on the ground and unscrew the relief or lowering plug. This lets trapped air rise to the top which can be bled out with the lowering screw. Did mine this way 2 times in a row and it works like a new one again didnt have to add fluid it was just air trapped somehow that would jack about halfway up and slowly lower immediately.
Don't pull the rubber fill plug with a load attached...you are relieving hydraulic pressure that way and the load can come down if it has alot of air in the cylinder.
I figured this same thing out. Extend the ram because you need all the oil in there you can get. I did the bleed process twice. Like yours, mine is working again. But....mine doesn't leak. Where did the oil go?
That is one of life's greatest mysteries. I don't have a definitive answer for you, except to say that there is a seal somewhere that isn't doing its job, and it isn't leaking at a fast enough rate to notice. Sorry, but that's the best answer I have.
@@oddjobsremigauthier if you look close after years of use it will be damp either around valve or around where cylinder comes out of pump. After a couple of years almost all will be damp somewhere.
@@MasonMurry-t9c not exactly certain what you are referring to. The cylinder can be separated from the hoist by removing the upper and lower bolts. The cylinder generally is a steel tube with a threaded cap on the top and is threaded into the base on the bottom. Does that help?
saved my bacon. to the engine all the way up with just the oil pan hitting and it stopped. filled and bled like you said and it went up and down non stop no problem
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?
sounds like the piston seals inside are bypassing. Mine did that years ago and it was easier to replace the ram( at about $90) than to buy the seal kit and open up the ram to expose the piston and change the rings.
@@oddjobsremigauthier Actually so when I changed the fluid I removed a small screw & put a small screw in the wrong way. Once I put it in the correct way all was well.
On my hoist it is a 3/8-16 tapered plug. it is the taper that is the seal, so it tightens to a stop. If your hoist has a rubber cork in it, you will not be able to use this technique. I can't really comment about your hoist without more info- and I am not a hydraulic specialist......so check out other advice for the best solution.
@@oddjobsremigauthier I've tried. I'm missing the bolt or cap that goes there. Fluid sprays out and won't jack all the way. Should I top it off and plug it?
@@nahno767 I can't tell you what to do with that since I can't see it. Google the manufactore and serial number. Contact them and ask them. If anyone knows what you can do, they will.
If you try jacking it up without a load? If it rises while under zero load, but not when under load, you could have a faulty piston seal. Be sure you have bled the system of air fully. Let me know how it goes. If there's a better way, I'd like to hear about it.
Video tips. When recording tutorial videos never put yourself between the camera and the object. May it be your body or your hand. Never block the object being recorded. The reason why is, the audience cannot see what you are doing because you are blocking the view of it.
Stupid video. "This is my first dumbbass attempt, then I'll do it right". People don't have time to fk around watch the whole thing and follow dumb steps that get get their shop sprayed with fluid for no damn reason.

@@oddjobsremigauthier I think your video is flawed. This isn't the way to do a bleed. That pressure is due to you having that jack fully extended.

We converted ours to be air assisted and it works beautifully for this older guy.
Thanks for the tips, hopefully I can fix my transmission jack the same way, it won’t go high enough and it has had a leaking seal.
According to the manual, the hoist should be all the way in the DOWN position, then fill to the fill hole.
Yes. Funny isn't it how that method doesn't work.

Thanks man. Smooth as butter now. Helped allot.
greetz from holland✌
Thanks so much man now i know what's the problem with My engine hoist is, where was this video 3 weeks ago.😅
This video is 3 years old! Haha! Still use it often.
Is the relief screw open the entire time you’re pumping air out?
Do you happen to know if I take a pipe wrench at the top of the cylinder the huge bolt does that unscrew to take apart the whole assembly
@@MasonMurry-t9c not exactly certain what you are referring to. The cylinder can be separated from the hoist by removing the upper and lower bolts. The cylinder generally is a steel tube with a threaded cap on the top and is threaded into the base on the bottom. Does that help?
@@oddjobsremigauthier yes what did you use to get that huge bolt on the top that has threads off a pipe wrench?
saved my bacon. to the engine all the way up with just the oil pan hitting and it stopped. filled and bled like you said and it went up and down non stop no problem
I am glad to hear!
I meant to ask...did you add that spring to your jack pump? That seems like a good idea. Would make jacking easier to do. More comfortable I guess.
Spring was always there.

Hey I just adopted a lift and found out it was yellow but painted over with red. You know the manufacturer of that lifts frame?
Probably "performance tool".
What size bolt and thread pitch fits it?
Thanks

@@oddjobsremigauthier ok fair enough. Thanks for the reply.
@@oddjobsremigauthier subbed
Thank you for the information
I’ve got the same problem with the exact same princess auto power fist hoist
Don't I know it. This trick will work, so long as the filler plug is a screw in type and not a rubber cork.
@@oddjobsremigauthier Yep if rubber it will shoot all over you.
Another good one Remi 👍🏻
Still not working right. Not fully extending.

Yes maybe your seals are bad?
Is that good for an international harvester 1066
This guy is awesome!
Thanks man

Thank you. there is much to learn.
You Are. Blocking. The. View. Of. What. You. Are. Recording. Gotcha.
I know, huh... and the explanation is a bit confusing. He says to open the valve, then he closes it instead.
\
@@davidhigginbotham5451 yea according to the Torin Big Red video you open it one whole turn & then pump 6 to 8 times to get air out.
Your little pump seals are bad. Still not lifting correctly. You cheated it for a moment.
Honestly, I had not even thought of the seals on the minor piston. 3 years later and it is still holding up.
@@oddjobsremigauthier if its not pumping its the pump. If it's not holding its the cylinder seals
Why the fk would you show it with boom down? I did this first and lost fluid. Dumb....
Why the fk would you just randomly do something you saw some guy do on youtube? Dumb.....
Stupid video. "This is my first dumbbass attempt, then I'll do it right". People don't have time to fk around watch the whole thing and follow dumb steps that get get their shop sprayed with fluid for no damn reason.
Volume sux.
Perhaps you need a new dolby surround sound stereo. They are on sale at cosco.
@@oddjobsremigauthier he had his volume too low.. great video my friend
