old floor jack repair part source

ok heres the deal. this was originaly my great grandfathers ausco 1 1/2 ton floor jack.its an old cast iron.he owned a repair shop,and used it there for many years.then suposedly it sat for a few years untill my grandfather got it working again.my dad as a kid remembers going with my grandpa to pick it up from the strorage shed to get it wrorking again.sadly my grampa mike died at a early age.i never meet him.i barely knew my great grampa.boo hoo.huh....well not really what this post is about,but id love to get this floor jack going again.i have it here,and you guessed it its been sitting in the shed for the last few years.i tore it apart last night.took the pump apart,and it looks like all i need is new seals.i cant get at the bottom seals since i cant get the cylinder out.it has threads on top,and bottom.anyone know how that is done?i can see how gramps repair failed.he took the wrong seals,and cut them to fit.they where just a bit too tight,and ripped apart.anyone know of a place that would carry a kit for one this old?thanks

Measure everthing with dial calipers,then looking in the Yellow pages under Hydraulics.
The parts are pretty standard,and pretty cheap.
Even McMaster Car lists O-rings in their catalog.
Make sure everything is CLEAN,and well oiled at assembly.

Worst case scenerio,takes the whole thing to any place that advertises hydraulic repairs.

 

thanks for the reply.the 2 main seals are umbreala type.im sure the originals where probly leather.the ones he made are rubber.i guess i dont need to take the sleeve out even.since there was just a brass peice i got out.

I have a similar situation. Years ago, my kid bought an old 30's era art-deco floor jack with lotsa deco lines cast into the jack's body....even has cast fenders and fender skirts [complete with speed lines] over the wheels and casters. I thought it would be cool to steal it outa his garage and rebuild it for him as a birfday gift but have been hesitant to "liberate" it from his garage and rip it apart before I knew if parts were available to rebuild it's leaky cylinder...

 

Just enter "hydraulic seals" in your favorite search engine,
and find places like this:

Any real old tool,or machine is probably worth fixing.
Even if you have to get some special machining done,it will be worth it.

 

yeah that kind of sounds like this one.its got the fenders too.i was alittle intimidated to tear into it,but the damn thing has been sitting for soo long i said the hell with it.
its soo simple its not even funny.theres nothing even wrong with this one.just needs new seals.a couple years back we had it sort of working,and it suroted a car,but it wouldnt work all the time.he he,and now it wont work at all,and leaks like a sive.i have to make a pad for it too.

i was searching all last night,but maybe i was too specific.
thanks a ton for the link!!

The seals don't know if they are in a jack,or a hydraulic cylinder.
Unfortunately,you can't just copy the seal that are in there.But it shouldn't be too difficult.

Yeh, Good info. I've got an old "Bosco" jack that I really like 'cause it's low enough to fit under a dropped axle but it leaks like a siv. I had a machine repairman look at it but he couldn't come up with a good seal/ Guess I'll tear it down again and see what sizes I need.
