The bitch pin, or "spring pin" should ideally be removed with an 8mm pin punch. I couldn't find an 8mm pin punch, at Sears, I bought some SAE pin punches.

A pin punch will have a rounded bump on the business end of the punch, that centers the punch into the pin.

Here is the trick. Once you get it centered on the pin. Hammer it from the top I connected all my 3/8 extensions together (a 12in, and 2 2in.) And just hammered it out from the top. It goes much smoother when you can fully swing the hammer.

This is the replacment part I'm using on my stock D16Y8 : http://www.slhondaparts.com/search.a...=90751-s04-000
