Not that it's important but I'm working on a Crown PTH50 5,000lb pallet jack. It was given to me missing half the pump parts from a failed repair by a local mechanic. NOTE keep track of all your parts. I had to buy a spare junk unit for $40 and a repair kit for another $40.
FLOOR JACK INFO:
The Safety Overload valve (cap that says DO NOT OPEN/ADJUST/TOUCH etc) is a valve that allows pressure to bypass/release if someone tries to lift something heavier than the jacks rating. This is generally only found on floor jacks and is a simple check ball and heavy duty spring. It just needs the spring pressure to hold the check ball in place. So tightening it to collapse the spring and then back it off anywhere from a 1/2-a few turns as long as the spring is still under pressure is fine. Most I've come across are around 1.5-2 turns out. It will just bleed off under heavy load/not allow you to lift if you have it set to light(more turns out). I always count the turns in to collapse the spring and then remove it so I can set it back. For safety it's better to have it set too light and you can adjust it after everything is rebuilt/assembled with a load on it. Set it light and lift the heaviest thing you have. For 3ton floor jacks I generally do the full front/both wheels of a truck, which is around 2 tons. The concern is if it is set too heavy and someone tries to lift a 4 ton object with a 3 ton jack(it will do it) the seals could blow or the metal structure of the jack could collapse, dropping the jack instantly. However most of use will never put a 3 ton jack to anything more than 1-2 tons so really not a huge concern how tight you set it.
OIL FOR YOUR JACK:
Any el cheapo oil is going to be the same or better than came from the 3rd world factory. Any oil will actually work; even power steering fluid, motor oil, etc. You just want a thin non-detergent oil(most hydraulic oil is iso 32/sae10) so the particulates settle out and don't float around the system. This is a good oil amzn.to/2us17lr . Detergent oils pick up and carry the junk with it and allow scoring/seal damage; which you don't want. Of course the cheaper oils will have less antiwear stuff in them, but unless you're using it in a high production facility it won't matter. You can put iso68/sae20 non-detergent oil in a worn out jack to get more life or even power steering + stop leak to swell the seals and get a few months/years. Lucas makes a good stop leak/thickener you can add to help get years out of a worn out jack amzn.to/2us0AQt

FINALLY, someone that actually explains how these jacks mechanically work. But also how, and WHY they fail. Can't tell you how many videos I've just sat through with "How to "fix" your blah blah jack" in the title, only to find out their genius solution is simply how to go about bleeding air out of the jack. Or adding oil. Bleeding is NOT "FIXING" a jack. Anyway, thanks brother man. Your video helped me out alot. Outstanding video! 👍

[@ampdrawrepair5352]

On the shaft pitting it may still be salvageable. I've used this technique to restore old car brake caliper pistons that you can no longer buy. Clean the shaft up real good with brake cleaner, wipe the pitted area with JB Weld to fill the pits, once it dries sand it smooth till the JB Weld is flush with the surface.

[@sixtyfiveford]

I've heard people having good luck with that method.

[@oldmountainmarineandmetals9736]

I have a practically brand new 27 ton Remington wood splitter that I was getting ready to do the same thing, my friend was trying to separate a log that didn't break all the way and he hit the shaft about half way in with a hatchet and marred it pretty good and now it leaks down after a while unless you store it horizontally

One of the best ways of seating the Ball in the valve is to make sure the seal surface is clean, (and not so badly mutilated it needs recutting!) Fit the ball and tap it LIGHTLY against its seat a few times with a hammer and drift. The ball should form its own seat. (Sorry if this is elsewhere in comments but I did a quick trawl and didn't see one.)😉

[@dannylinc6247]

Hydrauilc repair first rule: don't lose your balls. Second rule: notice the symptoms and notice how they had it. Inspect for the cause on teardown. Third : clean and inspect during diagnosis and under the paint for identifying numbers and name. When inspecting tearing down and diagnosing, have a container to keep it all if you have to wait. Use a container you won't need to use for something else. Keep moisture away. If you find similar jacks or rams for cheap you can find answers that aren't in drawings on a unit that's not been torn down.

[@patrickscahill254]

As an almost lifelong mechanic I've enjoyed taking things apart to get a better understanding of things, mostly things that have stopped working of course, for failure analysis. Keep the faith Ford man

[@sixtyfiveford]

[@COSMACELF1802]

Great video, thanks for the tutorial on check valves, that was awesome! My only 2 cents... be extra clean with the fluid. I once repaired my dad's floor jack (it suddenly dropped after jacking up the front end of a '69 Cadillac). The jack was only 2 years old, never abused. Upon opening, I found nothing wrong with the seals. I meticulously cleaned it, added new fluid and it's been working fine for the past 40 years. I suspect a bit of dirt, grain of sand or something found it's way between the seal and cylinder. Of course I went back to fixing the starter motor on that old Cadi, and something I can't stress enough... SAFELY USE JACK STANDS ALWAYS! The jack failed without warning, when it had already lifted the car. I was reaching for a jack stand and it just dropped at normal pace. It wouldn't lift anything after that.

[@dntlss]

Great info, thanks.

[@waltschannel7465]

I'm rewatching this video right now because I've got a Harbor freight floorjack that will pump up, but it won't hold. I bled it several times. No air bubbles. So I think the U cup seal is probably leaking. However I missed the part in watching this earlier about you may not be able to get parts, lol. Plus, I cannot find a way to get the huge nut off the end of the hydraulic cylinder loose. I think I just need a new jack. PS, YOU ARE THE ONLY VIDEO ON YOU TUBE THAT SHOWS THE COMPLETE PICTURE FOR JACK REBUILDING. Thanks for that. ❤

Poly pack seals is what they are called Most all hydraulic shops sell them so you could pretty much rebuild any jack

[@seanmullen2287]

Not quite that simple most Jack's built in the last 30 years are chinese junk that use special sized metric seals that are hard to come by. They love to put at least 1 custom sized seal that you cant get unless you buy a 40 dollar factory seal kit, that most of the time is not the correct parts anyway due to poor documentation. They are built to be disposable. If you can do it yourself it might be worthwhile. I used to run a hydraulics repair shop that's how I know.

[@tanksoldier9770]

Great lesson,I wish there was a Fix all jack parts store , I have some old monster heavy floor jacks only 2 and 3 ton rated and comparing with today's jacks the way the older ones are built they should be able to lift 50 tons , I have one old jack that uses air that folds out and lifts from under the frames but it has a harder time lifting a pick up with a big Diesel engine but it will lift all cars and its so much faster and safer than the floor jacks thanks TANK

[@mute8s]

A good thing to note that if you don't have the parts but you think there might be shmoo or water or something causing the balls to seat fully and you take it apart to clean it out DO NOT think taking the seals out and cleaning them will help. The only thing your going to do is mess up a seal that may have been totally fine.

[@sixtyfiveford]

Well said.

[@mrdddeeezzzweldor5039]

For reconditioning the check ball seat, I would silver solder a same diameter ball bearing to a piece of round stock of slightly smaller diameter (even a cut off nail could serve). A lathe would be useful for centering the ball/round stock for brazing. Then use a cordless drill and lapping paste to recon the seat. It is evident where Ginger learned her tricks from!

[@sixtyfiveford]

So I'm guessing this is a simplified version of what the check balls do in the value body of a transmission. I know we have perfected many ideas and have reached levels beyond levels of performance but just think about the level of brain power of the people who thought up these concepts when NOTHING WAS IN EXISTENCE OF THE SORT! Inspiration from things in nature or whatever into some manufactured tool that we don't even know life without! Those people didn't know life with it so the created it! That is something I don't think we ever give enough credit or never will even fully understand what it took to make that leap of creation into life we know today! Much Respect to those generations before us we so often take for granted and not even meaning to! We just don't look back enough at how we got to where we are things now move so rapidly!

You talked about when lift ram would "leak down". If the jack is not leaking oil on the floor and the pump handle is not moving up the problem is the release valve or you have a crack in the housing of the jack. In this case the check valves are fine.

[@stevewuertz3598]

I've seen dozens of these floor jack rebuilds but you've done the best job of describing the check valves, springs and cups. Hats off to you. I have a question.

Anyway for my education, what causes it to raise and drop like it does?

The holding check ball is just not sealing completely, allowing pressure to move back into the holding tank. Clean the check balls and their sealing surface and you should be good.

I would imagine it would take a lot of fluid or air pressure to explode the cylinder in the jack. The circle is very strong. I'm not saying it's impossible to breach the cylinder, but i would expect the seals to blow out before the cylinder.

"Have you driven a Ford lately"? Mines a 70 Falcon wagon. Good video 👍

Thanks, I'm glad you liked it.

i would like to see how you rebuild ram style cylinder jacks...the type that hook up to a pump and use either air or an electric motor to pump oil into the rams

I did a video years ago on hydraulic cylinders kzbin.info/www/bejne/jJazfmiApsaFfpI

[@fryreartechnology7611]

You can get a two ton floor jack for $24 from advance

Good helpful video, now I'm going to buy myself a broken trolley jack and fix it. 🙂👍

Frank you'll never believe what that knuckle head next door did today. He was riding a huge scooter down the street with his dog!

[@donquijote6030]

Albeit a late comment, I would like to thank you for the video.

[@sixtyfiveford]

Thanks, I'm glad you liked the video.

Great info! Thanks a lot! Do you happen to know why a "rapid pump" floor jack would go up quickly but then require several extra pumps before it starts lifting the car?

[@cwgreen1938]

Enjoyed watching you work on the jacks. I have a floor jack and a bottle type jack on a Harbor Freight lawn mower lift that I need to overhaul but neither one has a name or number on them, that I can find, and HF has no parts nor diagram for their jacks. How would you go about finding parts and a diagram on the internet for these jacks? Thanks

[@sixtyfiveford]

You need to take it apart and measure the bore, rod and seal size. Places like www.theoringstore.com will sell the U cups, seals etc by size.

I have 3ton Aluminum Jack that will not lift, it have 4screws close to the handle. But I'm sure which two is for bleeding.

Cool video Moe! Have a floor jack I’m going to try and fix now. Crown is right up the road from me here in Ohio, their main product is fork lifts.

[@sixtyfiveford]

Thanks. Crown makes some good stuff.

The u system is a clever concept / clever design,
