Blackhawk floor jack ID & advice

[19482255]

G'day all. Picked up a couple of vintage Blackhawk floor jacks cheap on CL about 6 mos ago in a package deal. Think they're rated at about 4 ton ea. Each jack requires repairs to be functional.

The stylish S4 jack is the one I’d like to keep. Does anyone know: where can I pick up a seal repair kit for this one? Among other obvious repairs required, the S4 is not pumping at 100% nor staying up under load. [emoji19]

Can anyone ID the model and vintage of the blue jack? It was originally painted red underneath the blue, but I can’t find an ID plate on it anywhere. I’ll be looking for a seal repair kit for this one too as the cylinder box is leaking. This jack holds up under load, but the arm does not return to position without assistance.

Any information about either of them welcomed! These suckers are amazingly heavy, but they’ll be just the thing for lifting some heavy old cars.

The blue one is also an S4. It's the predecessor to your red one. I believe the blue one is from the '30s and the red is around the '40s+. I have the red one and have been looking for that one from the '30s. I don't want to say "rare" but I don't see them nearly as much as the red one you have. Soooo jealous.... I'd keep em both if I were you. Sometimes having two large jacks comes in handy.

Thanks to both of you for your replies. Done some more searching and have found many, many BH-related threads. I've got a lot of reading to do!

Wow... Yes I concur!!!

blue probably 1930s and red 1940s.
I believe the styling changed and the rear wheel support and flanges changed considerably each decade 1930s, 1940s and 1950s.

How did you go finding the hydraulic kits? The ones I purchased from AMERICA weren't that great, only about 40% was relevant or useful and I think it cost me $200?
