Craftsman 50168 with two pistons really need help

[gasforblood]

Looking for a parts list or exploded view of a Craftsman 50168 4 ton low profile jack I believe pre 2013 with main piston and small piston on side. I got a seal kit but can not locate any diagrams for the check balls and such.

All I'm really looking for is where the 3 check balls (small, medium, large) and little barrel go in the block. Can anyone help?

Ordered a seal kit and it was wrong and now it's been to long since I removed them. I have the correct seal kit but now I'm stuck.

Anyone? Even if just an idea base on experience.
