I noticed you had a problem with removing the one pipe! Take a propane torch and Heat the base nut where the pipe is threaded into put your pipe wrench on it and put slight pressure on it heating this way you get the right amount of heat on it and not over heat it when it expands it will let go and you won't over heat it !
Killer video, thank you alot! Just wondering about your bench vise. Starting to collect and currently restoring a vintage wilton bullet vise. Just caught my eye is all! Thanks again
Hi. I have often received questions about possible jack failures. Most of the problems were due to the loss of the bearing balls from the jack valve. So I decided to disassemble a new hydraulic jack so that all the parts could be seen.
Is the o ring seal at the bottom of the cylinder required for it to work right? I have an engine hoist cylinder that’s similar to this, but mine has an o ring at the bottom. Do I need that? Mine was ripped in half.
The reason I watched and the one thing I really needed to see was the seal that goes around the release valve, it appears u just gave up on removing it, and most parts diagrams for these Jacks show a ball down in front of it too, all that I've seen, did this not have one?
I didn't want to break that seal, that's why I gave up on taking it out. There are several models of jacks. Behind that seal, some have a kind of conical piston, some have a ball bearing and others only have that cylindrical screw.
Saludos, disculpa migato tira el aceite por el tornillo qué esta cubierto por un plástico anaranjado pero ahí dise q no moverlo y vi en tu video q lo quitas y lo pones si lo aprito no pasa nada,el gato es nuevo y des pues de unos meses q lo necesitaba ya no tenia aceite,es pero tu respuesta gracias..
Hay una válvula de sobrepresión y está configurada en la fábrica para abrirse a una carga de más de 2 o 3 toneladas, para evitar fallas en el gato. Si aprieta la válvula con más fuerza, el gato podrá levantar 4 toneladas, pero existe el riesgo de que ceda y lo lastime. Si aprieta la válvula con más fuerza, debe tener cuidado de no exceder el peso máximo recomendado por el fabricante.
The cylinder rod only rusts if it is in contact with moisture. The gasket cleans the excess oil from the cylinder rod and there is no point in lubricating that rod.
I need to fix the valve under the large piston and you give up on removal of the cylinder where the valve is located. Nice video of I wanted to work on anything except that valve.
@@DorelBorlea Hi, and thank you for the quick reply. I really appreciate your quick response. Thank you for the video, it was detailed and well done, with the exception of the only thing I needed to know, which is where is the valve (ball) which retains the pressure when the jack is lifted. Mine bleeds down very fast and so I probably need to clean it or replace the ball or seat. I wanted to know where the valve was. Your disassembly provided everything except that. Thanks again.
I'm glad you liked this video. The pressure relief valve is located inside the cylinder. But that part is very difficult to disassemble. I don't think the ball or the seat is the problem. Probably a piece of plastic or dirt got stuck on the valve galleries. Try to clean them with air.
Gracias. Ese tornillo actúa como una válvula de sobrepresión. Si el gato no se levanta, la junta del cilindro principal puede estar rota o puede haber suciedad en las aberturas de la válvula.
Multumesc pentru video si explicatii! Eu am 2 cricuri de 2t similare cu cel din video si le folosesc de 4 ani ca sa ridic masini. De o luna nu mai ridica greutati. Le-am aerisit si umplut cu ulei pana la dopul de refill, se ridica in gol dar le pot apasa eu cu mana inapoi in jos. E stricata doar garnitura cilindrului principal sau si cea de la cilindrul mic pt pompare? Mai e altceva de reglat, de ex. supapa de suprapresiune sau garnitura de cauciuc din valva de retur?
Nu mai trebuie facut nici un reglaj. La supapa de suprasarcina nu trebuie sa umbli. Daca garnitura de la cilindru este sparta atunci trebuie inlocuita si curatat cricul de resturi de cauciuc.
For no name hydraulic jack is very difficult to find a seal kit. Disassemble the jack and see what the problem is. If you have a broken gasket then change only that one.
Lo mas importante no lo muestran bien que es el cauchito que va en el tornillo que se aprieta para subir mas bien es unico que se daña y no se consigue

Salut, am un trolley jack 2.75T , se ridică f greu și vine jos înapoi , chiar și cand e levierul pe deschis. Am desfăcut doar pistonasele și arata f bine , mă poți ajuta cu un sfat ?
Salut. Pot fi 3 defectiuni. Depinde de modelul cricului. 1. Garnitura de pe piston este sparta, caz in care cricul nu mai ridica. 2. Supapa de eleberare a presiunii are o garnitura cilindrica si aceea este ciupita. Din cauza asta cricul ridica dar nu reuseste sa tina greutatea. ( la minutul 1:50 in videoclip am incercat sa scot garnitura cilindrica dar am renuntat ca sa nu o stric) 3. Impuritati care impiedica supapele sa lucreze corect.

@@shekarmavathur9087 You're right. The jack looks like an old one now. To understand how a hydraulic jack works and what the components are, I had to sacrifice a new jack. It is important to know how to repair it and if we want it to look like a new one, it can be repainted. ;)

the stem of this jack has an o-ring at its base, that o-ring is covered with a kind of teflon gasket.
