Thanks for posting that Dragon, I'm assuming that is where the diaphragm sits?? Is that the plunger that pushes them in the picture??

What holds that plate in the middle? Seems it would have to have some kind of track or something?? Thanks for posting that. Keep the pics up if you don't mind...this will be a good repair thread for someone I'm sure!! I'm always up for learning how something works! lol Yeah, I read service manuals for fun. crazy
