Power steering problem slant 6 225

Ok so i took apart the pump, which i know now is a trw pump (very similar to the federal pump).
There was a snap ring infront of the spool valve i removed. I found some pieces of rubber from what i presume came from an o ring that is broken.
BUT i cant get the spool valve out i can press the spool valve further into the pump and compress the spring that is behind it but it just wont come out.
