Servicing Greylor PQ-12 pump

Has anyone changed the rubber seal in the pump housing of a Greylor PQ-12 pump? I would like to check the procedure for doing this. I have removed the housing front cover, front seals/spring, gears, and removed the delrin body from the motor. Just trying to figure out how to "push" the rubber seal out. Seems like there are two plastic retainers in front and behind the rubber seal.

Did you ever get a reply to, or figure out the order of reassembling the Greylor PQ 12?
