Hi all,
My jack has been fine for years but recently sprung a slow leak, so i've got a few questions:-
Symptoms
The jack is leaking from the end of the piston. It is the end that moves the lifting arm up and down, not the end that is pumped by the handle
It has got increasingly slow at lifting anything - you have to pump the handle 3/4 of the way before anything happens...then lift it and wait awhile before you can get another 1/4 of a pump in.
Questions
1. There is a threaded bolt in the top that you can undo and see the hydraulic fluid...I think i have accidentally temporarily fixed my jack by pumping the handle with the bolt out, and the handle twisted round to the unlock/lower things position. This has caused lots of bubbles to come out and i can now get a full pump out of it! 😳 😬
Is this the standard way of bleeding these jacks? was i meant to do this?
2. What fluid can I use to top it up!? brake fluid? or is this too corrosive on the plastic seals?
3. How do I fix the leaky cylinder end? I can undo bolts and do them up so long as I have clear pictures or a youtube video to follow!?
4. Where do I get new seals from? I've read in the past that some have leaked, are there stronger ones, or metal ones or something available?
