Old Floor Jack

[asallwey]

I have this old jack, probably Sears. I've been bleeding it and right now it pumps to 1/2 height, an improvement from 1/4 height earlier today. So I'll continue to bleed it. But I have a question.

What is the smaller plug that is sort of next to the jacking handle? The large one in line is the bleed & fill valve I know. The small plug will turn, and is snug.

Thanks, Alex

Let me try another question about this jack. Any ideas as to who sold this? I thought Sears, but nothing to identify the seller.

The metal label says it is a Hydraulic Trolley Jack, rated at 3000 lb., has a 15" lift, and is made in Taiwan. Age has to be at least 30 years as I've had it for 20'ish and it wasn't new. There is also a maintenance/instruction label, but no name. No serial or model # stamped on the metal label either. The pressure release is a screw next to the handle, not the handle that turns. The handle is not attached, just slips in. So probably a jack designed to be picked up and moved easier than one with an attached handle. So any ideas?

Ok, I think the screw I was asked about above is for the release valve.

I can't help with the specifics, but check out https://www.hcrcnow.com/

Quick search on their page found this: Might help

Send them a few pics and I bet they can tell you what you want to know.

They have all things floor jacks and sell rebuilt kits. I recently purchased a rebuild kit for my old Craftsman 50239 and it's working like new.

Rebuilding isn't hard. It's actually kind of fun to learn how these things work.

Thanks for the info, I'll check them out if I need parts.

I just did a Youtube search: 30 year old trolley jack. Darn if there wasn't a hit on a jack is very similar to mine. It looks like a little thinner metal than mine, but the pumping action and construction is the same. No name, but a good find. He didn't need seals, but replaced the o-rings from a box selection rather than a specific kit.
