I have a 3.5 ton Michellin floor jack I'm quite happy with. without looking I'm gonna guess it was made overseas...but it works quite good, doesn't leak and was affordable.

I have two of these at the shop and so far so good.

I never said it was... I was just saying for the dirt cheap price I've had good luck with it. He wants American made but he wants it cheap... that's not going to happen so I was just giving an alternative that I have experience with.





I wonder if there's any correlation between jack life (seals) and the way it's stored when not in use.
I'd been taught a long time ago that when a jack is not in use, to leave the relief valve wide open so that the jack is fully retracted. I'm not sure if this has any ACTUAL benefit or helps the seals not to freeze, crack or otherwise fail, but I've always had good luck with the jacks (and cherry pickers) I've owned and never had any leaks. This goes for some el-cheapo Craftsman ones, as well as some much nicer (albeit foreign made) floor jacks.
Anyone know if this method for not-in-use hydraulics really makes a difference, or is it merely a coincidence that my stuff has been trouble-free???

The only way it would make any difference is if the handle actually has enough weight to put pressure on the seals all the time. Maybe the constant pressure causes some to develop leaks, I don't know. I would think that it had more to do with how dry it was or large temperature changes.Never heard of this. I just leave it how ever it was when I last touched might be open, might be closed.
I PMed Dan @ ruff stuff, trying to convince him to build a bad ass jack out of the grade 50 structural steel he uses on his parts. He said thats a very interesting idea! I told him it would be very easy to make all the pieces for a jack with his capibility. Cut it all out, bend it, weld it. Not much more difficult then one of his bad ass diff covers I think. Just would need to get good US made jack pumps. All we can do is hope.![]()
That makes sense but I'm not sure whether it would make a difference if the relief valve was open or not as long as the shaft was fully retracted.i think it has more to do with protecting the shaft, when you leave it extended for longer than normal periods of time, that ram/shaft tends to built up surface rust, then when you go to use it, extending it and retracting it, that surface is not good on the seals.
This is what i have been told, and is actually just a bit of commom sense really.
yes, i always retract/relax the jacks/lifts when not in use. So far, the engine hoist is still alive, and it's pretty old looking, even the one i gave my buddy Paul.
