    I am new to HAMB and was led here by a search for info on my Blackhawk 4 ton rolling floor jack, that I would like to repair and use. I found an older thread, but was hoping to gain the latest info on what others have discovered about attempts to restore them. Mine is the S4 model, and is largely complete except for the lens on the headlight. Mine does not work, so will need the hydraulic cylinder overhauled. I was wondering if others now knew what was the best source for parts for these antique jacks. Did anyone ever determine what the key hole at the very tip of the handle was for. Anyone ever figure out how the headlight was powered or turned on and off? A con man duped me years ago on this jack, claiming to overhaul it. I tested it when he delivered it and it worked well. An older cousin explained to me how he had simply replaced the hydraulic fluid with brake fluid, which swells the seals for a temporary fix. I was so mad at getting taken I shoved the jack into storage for the past 7 years! Would now love to do something with it, since it is already a very expensive jack, based on my foolish mistake!! Some of life's lessons are very expensive! Ha

    The light is powered by a switch that is on the side of the "T" handle. The key at the top of the knob was used to lock the jack in position so that it could not be tampered with once set in place with the car up in the air and the user under the vehicle.

    Here is a pic of one (S4) that I came across online that's been totally refurbished. If you look closely you can see the little nipple of a switch for the light.

    Below are pics of the one I own.

    Great thread, I recently acquired my great-grandfather's old Blackhawk jack, it looks similar to these but with no light option. Right now it's at a hydraulic repair shop to see if they can get it working...
