Thread: Model 70 cocking piece removal....little help please

I am trying to replace the cocking piece on my post 64 model 70 Winchester firing pin.
I have managed to remove the spring and the retaining washers without loosing them but for the life of me I cannot see how to get the cocking piece from the firing pin ?
It appears to have a cross pin in it but it doesn't go all the way through so can't see an obvious way to tap it out.
Anyone got any pointers or advice ? Or should I stop here and leave it for a gunsmith ?
