Early Blackhawk S-4 jack - asking for more information

[Shelbylex]

Good evening

I am trying to get more information on this old 6000lb Blackhawk S-4. My guess is 1920s-1930s

Does anybody have this one? How heavy is it and how big is it?

Is it still possible to get rebuild kits for them somewhere or they are NLA?

Is it reasonable regular jack? (I previously got a wise advise from Hiball on S-18 jack (greatly appreciated) I wonder if the older model did npt require special tools and design was simpler (thus making it not too expensive for a hydraulics shop to work on it (and actually succeed) if it needs a rebuild)

Please let me know.

Hiball, if you will come across this jack - please share your wisdom with us as it appears that there are no jacks that you do not know!

Never mind, got sold...

Hmm, I guess I spend to much time looking for tools...

I found another one of these for sale (and like always not too close)

Thus I am reopening the thread in case I get lucky and get more advise...

There are a lot of us who have them. Is it right for you depends on you. They are very heavy for day to day use. But they are pretty cool too. Do some searching and you'll find threads about repair and restoration

I tried to look, but could not find any threads on this older model (found some for newer S-4). Can anybody point me to the threads or give more information

I will used it several times a year to rotate tires on my 3d generation highlander and other cars in the household (+ may be rare other jobs).

How heavy are they, whateg01?

My bad. I completely glossed over the age of it. The later one was about 200# iirc. More than I like to try to load into the back of my pickup by myself for sure.

Like all the Blackhawk models from that Era, there is going to be a lot of similarities in regards to seals used/methods of securement etc. I’m gonna guess the early 3 ton models didn’t go over too well, as the 4 ton updated model are found more frequently. If I was looking for a jack for basic vehicle maintenance, it probably wouldn’t be my choice. If I was wanting to bring a piece of history back to life, and get some enjoyment out of rebuilding it and using it in the shop. I’d probably take a stab, but know going into a project like this that it’s gonna cost some money for everything you farm out.

Thank you, Whateg01 and Hiball!
Hiball, your advise is always appreciated! Right now a person is asking for good money for this one - I will wait if it becomes very cheap and may be go for it knowing that it might cost me some to rebuild it (any guess on a ball park to rebuild hydraulics on this one?)

I guess I will try to continue looking for a relatively cheap Weaver in good condition then. (You are right - majority of the work would be farmed out).

... I still did not give up on my really old Weaver - just keep looking for another Weaver Utility to combine parts and make one working one...

Can anybody recommend a good hydraulic shop around Boston for my future jack (I will eventually find a good one!)
