1st step, Degreaser and a stiff bristle brush, followed by a power washer, makes for a clean job before and after, great video.
Thank you for sharing this. My husband took care of all this stuff and since he passed away it was left to me. I was able to fix his floor jack nicely thanks to you
Jack Mfg. instructions for bleeding is: remove filler plug open release valve and pump handle several times. Replace the filler plug and you're done. Firstly of course make sure the jack is full of oil.
Worked on both my Craftsman floor jack and my hand operated hydrolic log splitter. Thanks
I have had a similar floor jack,I picked up at a yard sale for $10.The seller and myself thought it was broken.This thing is a beast of a floor jack.Thanks so much for the information on refilling it.
Thanks for the clear and simple video. Needed to service mine I've had for about 15 years now. Your vid totally helped.
Thanks for the video, helped me get my jack back to normal. I did just what you said not to do before I saw this piece.
Yes helpful. I just saved $60 bought a repalcement pump jack and watched this tried it, loosened the srcrew to check oil, heard the air come out and retightened the screw- presto success.
thank you for posting!
Dude: Helped me fix my Motorcycle Jack today. Thanks for doing the video.
Glad it helped!
Thank you for such a detailed video. I have a old jack that is going to get this treatment. It was almost tossed out.
Happy that I found your video. This is exactly what is wrong with my floor jack, air in the system. Easy fix. I learned something new today.
Good luck with it!
Very instructive, practical- love the cowboy tune....
Good video brother, thanks for not cussing while making this video, many people now days cuss when they’re making videos on CZcams; I guess they don’t care if there is family around while we are watching these videos on CZcams specially around little kids; they probably don’t even care about their own families or kids.
We certainly care about whether or not our content is family friendly and have dedicated ourselves to leaving the strong language off camera. We want our videos to be suitable for all ages in the hopes some of the younger generations get hooked on working in the garage as we did. It is important to us that these traditions get passed down. Thanks for the comment!
Excellent job!
Your presentation is very good.
Thank you. This video helped us fix our issues with our jack. It really does work
Glad to hear it!
Thanks for the video. I have the same jack from Craftsman that I bought in 1986. Still working great. Now I know how to do a service on it.
Yep.. takes about 20 minutes and it is like new!
Thanks for the video. I put fluid in behind the handle and my jack obviously still didn't work. Found that plug forward of the handle and sure enough, I have my jack working again. You easily saved me $150. Thanks!!
Great video! I need to do this to my jack it needs oil bad. And now I know how
From the 412?
Buy you a beer sometime thanks.
I think this helped me figure out why my jack only goes up halfway then stops. It's got to be fluid.
Nicely done. Key takeaway from this vid... jack it up to top it off again. The reservoir fluid fills the cylinder and makes room to put more fluid in to bleed the air out. Anyone can miss that important step.
It's why jacks raise to a point and no further... not topped off and leaves air in the system. Hydraulic fluid is a non-compressible fluid. Air is HIGHLY comressable and ruins the efficiency of an hydraulic circuit.
Thank bro, I really appreciate it. I got the same older Sears jack will try to fix the jack not holding up.
Don't cut the tip off the oil, poke through the top with a pick or a needle. It will be a slower and more precise pour. Less messy.
They usually come with small holes already lolo
Cool thanks.
NOW ya tell me.
Thanks for the video. Very helpfull.
Great info, Love the sweatshirt
When you're in the scrapyard, you can usually find a similar old jack, and remove the spring from it.
WD40 isn't a lubricant, it is a solvent.
Nice clear video, thank you!
Good call! How did I not think of that?! Thanks bud
it was a silicone wd40 product, new line of ' lubricants' I saw for the first time in australia
I'm having trouble with mine, cant get the gears to move so the jack will be able to hold a load???? What am I supposed to do at this point? Probably just buy a new one??
@@philchvz18 A good penetrating oil is automatic trans oil mixed with acetone. That might get it loosened up if you keep it soaked for a week or more.
Should have thoroughly cleaned off around the seal before removing it. But the video itself is very clear, very simple to follow, and you’re only talking while doing the work. Well Done!
Love the adam sandler phase from happy gilmore, lol. Good vid
Great vid! Ive added oil to jacks before but that’s been about it. I really need to take better care of mine. It’s rusting away from brake bleeding sessions gone wild taking away the paint
dude.. truth! I am pretty sure 75% of my tool failures are because i am an animal when it comes to brake fluid. ratcheting wrenches, socket wrenches, jack stands...
thanks, good video
say thanks to so a lot for your video it aids a great deal.
As a Black Smith I'm saying only bend the spring steel while orange color , that cracking is stressing the steei
Best heat to orange three times let cool in ash or near heater After third cool down reheat to orange and bend to shape reheat to orange and dip in oil (veggies fine).
Thanks for showing
Great video!
Someone gave me a Craftsman Professional jack(chinese). I brought it home, lifted it in 3 pumps, let it down. Next morning looks like atf all over the ground. So, how do I flush out all the fluid? I realize I need to replace all seals. I hate to throw it out. Thanks
Great video! I recently found 3 old "junk" floorjacks here on the farm. Everyone threw them in the metal scrap pile. I now have a nice old school MACK trucks SUV, Truck floorjack that works like new now. I always had trouble finding a good one for my high in the air truck. Not no more. Also if this one you have ever does fail. You can get a GREAT 3 ton floor jack from Harbor Freight. They have the Daytona model one and they are top notch and the same that Snapon uses.
Those jacks are likely stronger than anything on the market today. good luck with them!
I have a floor jack, bought in sears, but need the address of some store to buy the stamp kit and Oring and the repair diagram, thank you very much and I await your response. God bless you.
I dig the happy Gilmore reference
Hey. I have a harbor freight floor jack that is very similar in design to your craftsman.
I can NOT turn the handle anymore. Any ideas?
It works. Jacks up. But I can’t turn it to release pressure. I’ve troubleshot the problem to being the handle not the piston or gear. I can release pressure by letting out oil from the (don’t touch) bolt instead of the “fill rubber nipple”. Or with a wrench to turn the bottom gear. Using WD-40 to try to break the seize. So I’m very confident its right where the handle attaches to the jack.
Thanks for any help and ideas.
You dah the man!
No, you dah man! ;-)
Love the Gadsden....
Heck yea buddy. Liberty over everything!
Million thanks.
Thanks
So I made a mistake and removed the small screw in the rear thinking it was the fill plug and the gear came up and I can't get it back in. Do you know to get the gear back in?
I have an expensive floor jack. When I put pressure on it jack oil shoots out around the rubber plug. Help please.
When you pour the oil in don't forget to put more dirt in with it, it improves the oil flow through the orifices inside the jack. If you going to do a video about a floor jack service at least do it right. Clean around the fill plug before you open it!
Do you know what websites to order the seals an stuff for the jack mine doesn't have a name I bought mine in 1995 an there is no numbers on it either
Same symptoms with my circa 1983 Craftsman 1 1/2 Ton jack. Found the plug and will refill and bleed. No obvious leaks, just used and abused.
You should bleed with valve full open first pump 10x. Any cylinder jack that sits needs to be bleed this way before use. I work for SPX hydraulics
Yes u can use hydraulic oil in a "hydraulic" jack best stuff I found is cold weather snow plow fluid.
Generally AW-32 or ISO-32. Dont use the thick stuff.

Bad habit of not cleaning everything first. The grit that is being held from the old grease is still there. Also, you ran a sizable risk of getting dirt and grit in the fill hole. One more, you should always lube the spring you altered to keep the arm up. The sides of the coil constantly rub against each other.
Thanks! A jack can have bigger problem. Like inside the cylinder and it is needed to service it with a kit.
The two gears that turn when you turn the handle do not turn. Is there a way to get them to move. Can they be lubed somewhere?
I took my original to me Sears Craftsman 2 ton jack handle apart and my bolt also had this sharp edged piece of metal from the lock washer friction that dug into it. That sure could have torn some flesh off one's finger if not careful.
What about the surface rust on the pad and elsewhere? Should it be power washed before filling etc?
Yea, try to wipe it down if you can
Wouldn't dipping the hot coil spring in cold water/oil quickly cooling it, get it back to its original "tempered" state? And work like a spring again? Slow cooling bad me thinks. Appreciate everybody's garage tutorials.
If you quench it in water it will probably make the steel too brittle and it will break again. Try quenching in oil. It will take a little longer, but will keep the steel more ductile.
Less than half a second into pouring: "woah, this thing is taking a lot more than I thought it would!"
What is the diameter of your pump piston on your Craftsman 3 ton floor jack?
Honestly not sure. I will have to check
Good job
i did this today. seems to operate more smoothly. only thing mine is still dropping too fast when releasing the jack
Did you find any resolve to the fast drop? I'm afraid mine (old Arcan steel blue 3 ton) will still drop too fast(its a turn handle release) as I need to graduate my use from using stands to not kill myself in the event of jack failure to actually putting the car on stands. I'd think cleaning and re-greasing the external mechanism controlled by the handle would get that back but your comment gives me doubt now. I'd really like to avoid replacing as this Arcan was over $200 new.
@@MassiveLoop no i never messed with it anymore after that. it definitely still drops too fast. not sure wtf is going on :/
Thats the adjustment screw that says do not adjust is for just that
I have a 2-1/4 ton floor jack with no data plate. All I can tell you is that it’s a heavy duty and it’s orange in color. How can I find the right repair kit?
Grease the plunger slide pin at the top.
the problem that I have is the handle will not twist to lower the jack. Any ideas.?
Okay...I did this with mine...and I put in a bit too much fluid, and it caused that rubber cap to pop off, and now I cant find it.
Got it.
Thanks Man great video made a subscriber out of me.. Lol
Nice one and thanks for the tip about the location of the refill hole. My only concern is that the area around the refill hole should have been cleaned before refilling. The dirt there could fall in with oil and make its way to vital internals.
So the screw where you filled up is that the cylinder? I guess what you're saying is don't fill in from the reservoir bolt?
That is correct
The plug he is removing at 2:09 is the reservoir plug, the fluid he puts in is going directly into the reservoir. At 1:38 he is pointing to a flathead screw, which is the overload bypass valve. It probably originally came with a cap or sticker that said “do not adjust”. It’s a safety mechanism to prevent any damage from overloading the Jack. If the Jack capacity is 3 tons, and you try to overload it by trying to lift 3.5 tons, a valve underneath that screw opens and any attempts at pumping the handle will result in oil going right back into the reservoir, not going to the main ram cylinder, so that jack won’t even try to raise the load. Basically the jack knows if it’s being overloaded and will protect itself (and the user) through that valve. If you mess with that valve, you screw up the setting of the safety mechanism. therefore, “do not adjust”.
I mistakenly loosened the slotted fill hole (the one that you're not supposed to touch) thinking it was the thing that let the air escape when bleeding. Is the my jack messed up now? I tried tightening it again, but I am not sure if I permanently messed/de-calibrated it.
You should be ok, just do a really good job bleeding it
If ATF is corrosive, why do we use it in our transmissions.
Should clean the area around the filler hole before removing the plug.
Just the tip...That's what he said....
Just the tip and only for a min. Works for me every time!
Been using baby lotion most nights but I'm switching to jack oil for sure now.
Watch out, it says stop leak on it. Too much and you may keep jacking and nothing happens
You can order a new spring from ebay for between 5 and 10 dollars. You can also get a new rubber filler plug.
steam clean it first then apply degreaser then steam clean again.
Blow the dirt off the fill area with compressed air before taking the cap off!
Great job, but you should have cleaned it first with brake cleaner.
My 3 ton jack is 2 years old wont began to lift . added a bit of oil , stil wont even try to llift .
Did you try bleeding it for air?
@@DEInTheGarage Yea about a dozen times .
Cheef Cherokee
Time for new o-rings
Grease up the shaft.
i cant find anywhere why my 3.5 ton takes likes 20 pumps to go up? i bled air and topped off ect , no difference
How do you Fix a Fact ?
Wooly Highlander easy! Here’s an example: Fact, your comment is stupid and wastes people’s time who read it.
Fix the fact: delete your comment. Problem solved and fact fixed. 😂
probably flushing the old oil out is also a good idea
Don't worry... I always cut towards my thumb, not my chum!
how about you clean it before removing that seal jajajaja
luis m jaramillo indeed, dirt is the worst enemy of any hydraulic system!
Split ring == Lock washer.
“WD40 will rust horribly after it dries up!” the silicone is a good lube for the jack
If your "jack" could talk...what stories it could tell!
It would definitely tell some stories of sketchy repairs I have made...More zipties and Kentucky Chrome than I'd like to admit!
"Please unload your mother from me."
MAYBE...you should have pressure washed it before you started working on it!
Washer??
First step. clean off the jack to the eat off it stage.
should have pressure washed it before you started
I wouldn't let him work on anything of mine.
He sure should have "Hang on I'll pull the bung out and let all that dirt and crap fall into the hydraulic system"
Or use degreaser.
Exactly, or at least use some brake cleaner to wash down that grime near the plug...
This guy doesn't know Jack.! Just kidding... I learned a few things, Thank You.
Lol.. Doesnt know "jack"
I've got the exact same vintage of craftsman jack, I thought the poor little guy needed Viagra.
You saved me a trip to Harbor Freight, and money I didn't need to spend... Thx
Mime got water in it
WHAT A FUCKING CRAFTSMAN!!!! Lol. Good job buddy, I would have external a small bungee cord that could be quickly removed but hay...
Most of these yo yos have no clue. STEAM CLEAN FIRST!
ATF-oil is NOT corrosive to rubber. It is the best fluid to preserve rubber. Check it up! (Not on YT)
I heard that ATF oil will compress a little.
At least use brake clean spray to clear the debris before opening it up. I cringed when you ran that cloth over the open port.
It's 27mm, that why your sockets don't fit.
Too good for your hole? You're killing me. I can't type all my comments.
Bahah... You kill me Frank. Always look forward to seeing what you have to say on the recent upload!
🤢 the Steelers!...really...UGH!
Don't judge me on that sweatshirt alone!.. I am actually a lifelong Bears fan. My Wife is a Steelers fan, so I put them on my back as my AFC team...
Why not drain out the old oil? When you change the oil in your car's oil sump or gearbox, you first drain the old, corrosive, less effective oil then add fresh oil...
This oil does not go through heat cycles as the oil in your car does. The heat is what degrades the oil. There is far less heat involved with the compression force of a hydraulic jack so draining the old hydraulic fluid is rarely necessary
@@DEInTheGarage Interesting. I would probably change it anyway just to have it at 100% (it does degrade a bit with time and use) but it also doesn't take much oil and oil is fairly cheap...
👍🤣✌️
