How many O rings? Case 580B

[mblair441]

Pulled the power steering cylinders on my Case 580 B to rebuild with an O-ring kit from YT. The piston head had two O-rings. The kit did not contain two O-rings for the Piston head, just one which fits deep in the groove. There should be a second ring to make the piston head seal against the cylinder wall. I cannot find this set up on any of my parts diagrams. What size and type should that O ring be? Is there a part number and source?

Did you use the correct serial number when you ordered the kit? Serial #8735171 and up uses this kit.

I ordered the kit over six months ago and thought I ordered the correct kit with the serial number, but it is entirely possible that I didn’t get it right. I will double check.
