Replacing valves on an electric 395M. The best way to describe the valve assembly is 3 pcs. White plastic sleeve that the spring attaches to, and then there's a round red seat with a hole in the center that the sleeve attaches to.

Please refer to figure C10 and the photo. Part # 9.001-105.0

How in the heck does the round red valve seat fit into the cylinder assembly? Can't press it into place. Is there a special tool or technique? I tried for about an hour and gave up. Thanks for the help!
