Changing the Main Shaft in a Walkera 60

[PaulW]

I just decided to fit the Alloy head upgrade to my Walkera 60
(Have been having tracking problems since damaging a set of main blades on a garden chair I discovered the feathering shaft is bent so decided to fit the alloy head and Main Shaft it came with)
I am having diffuculty removing the old Main shaft, it seems to attached to the auto-rotation / main gear assembly by a pin. But before I strip down the whole helicopter and try and bash out the pin I was wondering if I had missed something obvious, and if so what?

Help!!!!!

Answer to my own qusetion, after some interpretation difficulties Walkera helped me out, and yes you just bash out the pin, and you need to, the mainshaft for the alloy head is shorter and drilled diferently than the standard shaft
