In my experience, slow steady pressure works better for removing sealed parts that a sharp blow from a hammer. If you can get a porta power or even a long prybar on the inside and push, it will start to loosen and move.

Thanks

Padraig,

Turned out to be WAY overkill. It just came right out. But it sure made it easy. I was expecting it to be a “cinch it up, wait, cinch it up, wait, cinch it up”, rinse and repeat ordeal. Nope. Just started turning the nut and it pulled loose. I like those kinds of battles.

Thanks. Brad.

I will let you know how it goes as I was a little cra-cra with my use of 5200

496Blower,

Thats where that “cinch, wait, cinch, wait” is prolly gonna be the thing. But that’s the awesome thing about this “puller”. Give the nut a twist and let it sit.

FWIW…. I’m planning on reinstalling with 4200.

Thanks. Brad.

Corsa sent my old ones back to me, but they have new flappers and they’re PRETTY!

Now I just gotta get the old sealant/adhesive off and get them back into place.

Thanks. Brad.
