I wish I had the skills to do any gear box work. I once tried to take apart a V3 to replace some parts and faild.
So I paid a gun tech to put it back together for me. Then I tried again to see if I was able to do it and faild again so I smashed it with a hammer,and that was the last time I ever attempted to open a gear box lol.
I need some one to site down and teach me,thats the only way I will learn the ways of the force.
So good for you being able to do it on the first attempt
using just the internet and you own knowledge
