Blackhawk SJ2 Floor Jack with Craftsman badge

Based on my reading of several posts, I believe I've picked up a Blackhawk SJ2.

Some of the other threads told about these jacks being imports sold by Sears. However, I have found in two places where it is stamped "Made in USA."

It is the typical green/blue metallic paint color.

After searching for quite a while, I couldn't find an answer to the behavior it shows:

1) I added new fluid to the appropriate level and tried to purge any air left in the system multiple times.

2) When the handle is pumped, the lift arm goes up a half inch but returns immediately

3) I pulled the lift arm up about 3/4 of the way (with the handle release tightened) and the arm stayed up. I then pumped the handle and the lift arm continued to raise up. It stayed there for a few minutes before it slowly went down on its own.

4) Trying again, it did it again. After reaching 3/4 height I loosened the handle and the jack went down slowly on its own. I put it to 3/4 again, loosened the handle "wide open" and it went down quickly on it's own.

For the kicker....after all this there was not any new oil leak to be found

Suggestions?

Thanks to Hiball for his help with a kit. It's on its way and I'll post how the "surgery" comes out.

If anyone is doubting buying a newer jack from the local auto parts vs. rebuilding an old one.....just move them both around; look at the steel; see the joints/welds/bolts. There is no doubt which you'll choose.

I had some work to do on the front end of my son's car. I was a little disappointed that I wouldn't be able to use the jack right away. The good thing is, it was so beefy and made with such real American metal--I just tossed it in the trunk and it was so heavy the front end of his car came off the ground
