Seiko Quartz Chronograph Pushers Stuck

[LumeShot]

Hello everyone. I replaced the crystal on a Seiko SNDA57 quartz chronograph with the 7T92A movement and when I went to recase the movement, I tested the chronograph pushers to see if everything was working as should, but the chronograph pushers would no longer push back out. They can be pushed in, but there is nothing to allow them to "spring" back out. Any advice? Thanks!

Open back up and recase, the pusher is not against the brass tang and is getting stuck. No spring in these just the pressure from the brass lever. If very stiff the rubber o ring will need in the pusher will need a grease or if hardened replaced.
