Looks like my bottle jack has lost some of its oil, thought it was PS fluid blown by fan onto the jack but the jack only jacks so far then nothing. I am assuming it has lost its oil. My question is how much and what type of oil is required? Hard to change a tire without a jack.
Thanks

Just to let you know, I think this has been asked before and answered. I have looked but was not able to find it. So I am not lazy..... dumb maybe, but not lazy. :-)

Any light oil will work-even brake fluid. Usually, they spec it out as a 10 wt. oil.
Think about it, what is your brake system, but a hydraulic system. Same rules apply-in general. |

Sears sells replacement oil for bottle jacks for about $1.99 per bottle if I remember. I saw it at the local sears hardware store the other day when buying my floor jack. |

Perfect. Now I know what, any body enlighten me as to how much to put in it? Or is it one of those fill until full?

me too..
i tried to refill mine. buy taking the oil plug out and filling the bastard up to that point, then pumping the handle up and down to purge it. and replacing the plug... but it didn't work. i'd love fix mine.
fortunatly there was a harbor frieght nearbuy and i bought a 6 ton bottle jack for 18 bucks.. so i can figure out how to repair this thing at my convenience.

Aw crap. Now I have to ask how too. I thought it was a simple procedure of taking out the screw that you use to lower the jack, and filling with the correct amount of oil. Is that incorrect?

I had the same problem, sir. I purchased the sears fluid that has been spoken of as well, which is designed for repairing their bottle jacks. There is a little rubber tab which can be muscled out to re-fill it, however it's not that simple. I like to consider myself mechanically inclined, and I tried for houres to fill the damn thing right and in the end managed to drench myself in the fluid. My advice would be to take it to the dealer. It is a warrenty item, so if yours is still in effect they will give you another, otherwise have them service it because it is a royal pain to do. |

"work-even brake fluid."
You are ASS U ming that those seals are brake fluid proof. I would say they are not.
USE HYDRAULIC OIL!
$1 a quart at any farm/tractor place, or in a 50 gallon drum if you prefer

Found this. I haven�t tried it yet so I can�t confirm if it works or not.
Check Oil Level
With the jack in the upright position and the ram completely retracted, open the release valve by turning the release assembly counterclockwise. Remove the filler plug � the oil should be just up to the hole. Fill if necessary with clean hydraylick jack oil. NEVER USE MOTOR OIL OR BREAK FLUID.
Lubricate Internal Components.
With the release valve open, pump handle six full strokes to assure proper internal lubrication.
Bleed Hydraulic System.
During transit hydraulic jacks may become �air-bound�, causing spongy ram action. To bleed the hydraulic system � close the release valve by turning clockwise. Insert handle in socket and pump jack up to full height. Open release valve, invert the jack and force the ram to retract. Repeat as required.

OK, does anybody have any chemical composition data comparing the brake fluid with oil?
How about chemical compatibility data on either oil or brake fluid? Chemical compatibility on the seals used on the jack?
Seems like I'm being bashed for conjecture with potential conjecture.
Corrected if needbe!
