Installation tips for kohler 84676 flush valve gasket?

[Murphysf]

Hello

I have a kohler 3386 and the flush valve gasket is shot.

In these two videos it seems like it is really hard to compress the gasket to get the flush valve back in.

I'd rather not compress it over night in the freezer.

Should I just go for it like the guy in one of the videos and push like hell to get it in?

Any tips or tricks?

thanks
