So I took apart my Craftsman 2.5 ton floor jack because of a leak, and found the culprit, a wide seal or o-ring that sits at the bottom of the pump assembly on the opposite end as the gland nut. It's leaking pretty badly and appears pretty beat up, possibly from having been overtightened at the factory. In any case it needs replacing. Every other seal, o-ring and part appears to be ok.
The problem is finding just this seal without having to shell out over $40 for a seal kit which I don't need and is almost as much as I paid for the jack. It's only a few years old. If someone knows the part # that would be great too.
It's the seal that's removed at the 6:00 min mark in this video.
This is the exact same jack I have even though it's branded differently. I'm guessing that this seal is a certain kind of seal with a certain kind of name, that might even be a generic seal that's used in other types of tools and contraptions and isn't specific to this jack. But I don't even know where to begin to look.
