Another Overseas Floor Jack Rebuild Question

[windswept4]

Hiball did such a good job on his tutorial called the Overseas Jack Rebuild Tutorial, I'm hoping someone can address my jack specific question:

I acquired a floor jack with no identification other than it is painted red and claims to be a "BlackHawk" with an 1,875 Kg capacity # GG920904416. A national service shop rep says that's not a valid domestic BlackHawk id number so I figure it's an oriental counterfeit.

During disassembly all the BB's (check valves) and needle valve and spring gushed out with the jack oil so i dont know which item goes into which drilling hole. The 2 small BB's (check valves) measure .025 inch in diameter and the large BB (check valve) .035 inch diameter. The 4th check valve "BB" is inside the release valve hole and I know this check valve is properly located because it never fell out of its cylinder and is still in there.

I have guessed at the location of the parts and have laid them out in a line with each drilled cylinder (see photos so see how I have laid them out); but this is only a guess! Can one of you take a look at the photos and tell me which parts should go into which cylinder and in what order?

Once I get some help on this, I'll rearrange the exploded view of the parts in to show them in the proper location; then I'll take a new pic and post the proper order.

Many thanks in advance to Hiball and any of you for sharing your experience with me on this.

I hope the links to "photobucket" work ok. If you can't pull up the pics, let me know and I'll try posting again.

More info from me:
The release valve drive (a small 1/8 inch half moon drive shaft) turns clockwise to seat a 4th ball (check valve) and counterclockwise to unseat the ball. That ball rests directly under the half moon drive shaft that is driven by torqueing the jack handle shaft clockwise or counter clockwise. That 4th ball is visible in the photo attached below. It never fell out (the 1/2 moon sized washer prevented that 4th ball from falling out).

That still leaves as a mystery that lone small ball that is shown to the side of the other parts. "Hiball" has speculated that that ball to the side may have come out of the side port. I'll be trying that this weekend.

I want to show you a photo of the release valve and if you look inside the cylinder that has the 1/2 moon opening (I believe this is the release valve part) you can see the 4th ball already inside:

Hiball has confirmed that the jack is not really a US Blackhawk; but instead is 100% foreign (non U.S.)

The needle valve and 3 loose check valves (bb's) seem to be my biggest hurdle. I'm ok with the wire filter screen, the main plunger all the rubber O rings and the pump plunger. I'm not ok with the 3 check valves, the needle valve, the spring, and the overload adjustment screw. There is an allen bolt on the side of the main block assembly that might be the location for one of those small check valves...have you ever seen a drilling on the side of the block like this (see the side view picture)...and what goes within that particular cylinder (one of the check valves?)

Many thanks in advance for sharing your experience.
