Well my model 250-12600 1 1/4 ton Sears quit working 30 years ago. It rolled up the piston seal and I've never been able to find one at Sears or any other jack parts house. They all say just junk it and buy a new one!
Problem is, I hate to throw away anything that could be fixed with a $1.00 part, if you could find one.
