Pana la urma, ai renuntat la maner?! La surub respectiv piulita, n-ai intervenit deloc. Cred ca aera nevoie de o curatare si o gresare. Un ...mic like!
Multumesc!... Am renuntat la maner pentru ca vreau sa folosesc cricul acesta la o presa hidraulica. Surubul se curata destul de greu si de asta nu am insistat pe curatarea lui. Inca nu am gresat surubul dar urmeaza.
@@DorelBorlea Yes, I know how it works. I still think the reservoir should only be 2/3 full of oil. This is because when you pump the oil goes from the reservoir into the cylinder, which creates a negative pressure in the reservoir. Without any air in the reservoir, theoretically the fill plag should be sucked in during pumping. Manufacturers of bottle jacks fill them with oil only to 2/3 capacity and this is also what they advise in the user manuals As you can see in this video, the factory-new jack was not fully filled with oil by the manufacturer cause not a drop of oil spilled out of it after removing the plug: How to Reverse Upside Down Working Position Of Hydraulic Jack ua-cam.com/video/A5OqaWyVWZ4/v-deo.htmlsi=GwyTtoYVJ3VHhUtx&t=70 Home hydraulic press.

I don't understand what's so funny. I mounted this jack on a hydraulic press and it works perfectly. And I did not use any complicated anigravity device :)
@@tomnone8378 The jack is mounted on a hydraulic press. The main piston is tensioned by some springs so that the gravitational force does not affect the valves. Check out this video if you don't believe me: How to repair a clutch with a cheap 20 ton press ua-cam.com/video/N2b5-9P2CIE/v-deo.html
@@tomnone8378 This system works due to the viscosity of the hydraulic oil. When you operate the small piston, that valve closes due to the viscosity of the oil and as a replacement for gravity are the springs that retract the main piston. Probably if we replace the oil with water then this system would not work.
Super!Un mare like! Salutare!!!!!!..
Multumesc. ;) Te salut si eu.
Wow

👍👍💪
Y los repuestos del de patín ocupo las llantas con su estructura completas me podría ayudar
Tengo taller pero mese sito repuestos
Way too much oil! The oil level should be just below the oil fill hole.
Because the jack is upside down it is necessary to use an external barrel with oil or fill the bottle jack with the necessary quantity of oil.

upside down :))) ha ha ha what about gravity :) and non-return valve's ???? hahahaha :)

@@DorelBorlea what about ball in valves ? How that works
