Help needed with floor jack

[stash69]

Hi, I have an old blue and white floor jack, I believe it's an old sears model.
I recently decided to rebuild it as it wasn't holding pressure and it was leaking.
Anyway after changing the main piston seal I stupidly turned the jack upside down and managed to empty the two chambers on the main body, now I don't know how many ball bearings were in there and where the fit, I have found two ball bearings but think there may have been more?
Can't find a diagram anywhere on line.
Can anyone help me as the jack is old but very well built and hope to get it working again.
Uploaded pics of jack.
Thanks to all in advance.

HCRCnow.com has a bunch of hydraulic jack diagrams from old manuals online.

Looked on various websites and have found nothing...I've looked on YouTube and found a similar jack, Shinn Fu.
The 3holes shown on the photo are numbered as I believe the parts should be fitted, the YouTube video shows the non return valve as number 2.
I've put the jack together in this way and after filling it it just won't jack up at all.
Anybody know if this fitting sequence looks correct?
The items looks like hey will only fit in the sequence that I've shown?

The spring should be in #3, above the cone valve. The nub on the inner screw should fit into the spring. It is the overload valve. The tighter/further in the screw, the higher the pressure setting…

Yes, that's correct, I took it all apart again and through trial and logic figured out that the pressure release valve must have a spring. All working as should. Thank you for your reply.
