Hydraulic Jack Repair

[hp246]

My hydraulic jack gave out, and I need some information on how to repair the darn thing. It is a Prov Value 2 ton jack, model 1202. It was purchased from Carquest. I bought the repair kit from Carquest, but all I got was a bag of parts with no directions. Carquest tried getting a breakdon for me but they had no luck either. When I did a search of the internet, I found a lot of generic information, but nothing specific to the jack that I have. I can't even find a mention of the Pro Value line of jacks. I suspect it is manufactured by someone for Carquest. If I knew that information, I could problaby have better luck with an internet search. Anyone out there able to point me in the right direction?

Hydraulic jacks aren't very complicated. I would clean it up first, then carefully disassemble it (keeping notes of what came from where, if you might forget), look at the parts to determine which has failed (probably a torn 'O' ring or seal), clean all passages, and reassemble in the correct order with new parts where needed or supplied.
Should not be more than a couple of small springs, a check valve ball or two, a cup on the plunger, all simple stuff if you pay attention to details while disassembling it.

The repair kit has about 25 pieces in it. Most of them o rings in a large assortment of sizes. I didn't think there could be that many seals in the thing. I would feel much better about tackling it with a decent breakdown in front of me.

It's probably a 'one kit fits all jack models' situation so only a few parts are really needed. Just compare old parts with the new ones to decide which to use.
Some of the stuff I fix was made before even radio or television existed, so finding directions anywhere, including the Smithsonian, is impossible. Have faith in your ability to figure it out, and take good notes with sketches. ;)

Appreciate your response Old Iron. What type of hydraulic fluid do they use? Can I use something like Type F? One post I saw said use hydraulic fluid or 5-30 motor oil. I have Hydraulic Fluid, but it is 90 weight. THat doesn't sound compatible with 5-30 motor oil.

Also,
The kit I boust is model specific. It shows it is for the 1202.

A hydraulic oil in the ISO 20 to 25 range is what you need. Standard farm-duty light hydraulic oils are in the 32 range, so go lighter than that.

Take pictures of the parts you have in the kit and post them. Or PM pictures to me and I'll give you an idea what's what in there. Include a few shots of the jack's power unit too.

Try "hydraulic jack oil". It's available all over the place.

I've used automatic transmission fluid and power steering fluid in a pinch.ATF is hydraulic fluid with coloring and anti-foaming agents.PSF may or may not have coloring.Had to "McGyver it " at 2am with the engine half out of the car and the engine hoist losing pressure.
