Floor Jack Rebuild Advice

I have a cheap 3-Ton Floor Jack that has sprung a leak.

I'm going to take it apart and try and fix it. I'm assuming it is just some seals.

Does anyone know what sort of oil they use? I've got tractor hydraulic fluid is that good enough?

Anything else I should be aware of?

Thanks,

PB

Many years ago my dad use to repair jacks as a side job. After he bought the insurance he figured he needed he quit. Anyway some of them can be a bear to take apart. I remember helping him. Before you take it apart make sure you can get a repair kit that will have all of the seals and balls. Do a Google of Hydraulic Jack Repair Kits.

A rebuild will cost more in time and aggravation that just buying a new one.

If the seals are leaking, it has become extremely untrustworthy. Get a new one, a better one.

(One man's opinion.)

A new one is only ~$99. I abused the crap out of this one dragging it around on gravel driveways and other general use for over 10 years.

I'll take it apart and see what I can see just for fun.

Yeah, you can buy a cheap one for less than a $100.00 bill. If you can find the seals, the time to track them down and then pull the unit apart to repair, you would be farther ahead with a new Chinese version everyone sells now,which work OK anyway, just make sure to use jack stands.....

As far as the oil goes, you can buy the jack oil at most part stores, use the tractor oil you have or ATF. They will all work just fine.

They make special hyd. jack oil. I don't know what is different about it - oil is oil... isn't it ???

I've put a new o-ring in the letter-outer before but haven't disassembled the jack part... yet.

Good luck, PB. Let us know how many pieces it is :rolf2:

Some oils foam, high pressure aditives, some have detergent in them and other oddities. Hydraulic oils generally don't have anything but the oil in them.

My dad replaced some O-rings or seals in his old Craftsman jack and he ended up buying some Hydraulic Oil. They said there was a difference in Hydraulic fluid and hydraulic oil. It works good.
