It really is very very easy to do but the 9 speed mech needs to be a shadow for this to work.
Don’t worry about the spring as its not connected the the knuckle you are taking out it clips to the parallelogram itself.
Stuff needed
1.5mm drift
2.0mm drill bit
Vice
Hammer
1 Drill dead center with 2.0mm drill bit as you can see in the pic and just drill down until you just see a glimpse of the pins.
Your not drilling out and material where the pins actually sit so it doesn’t effect the strength of anything.
2 Tap pins out with 1.5mm drift(i put a 1.5mm drill bit in the vice and cracked it off just below the drill threads…ideal)
3 They come out easier than you would expect.Take care to not loose the four rubber O rings that sit in recesses in the knuckle you are taking out.
4 Swap over the 10 speed clutched mech and cage (with the four O rings)
5 Refit pins but make sure you turn them trough 90 degrees so that the two barbs(on the end that you are tapping back in with the for mentioned hammer 🙂 ) have fresh ally to grip so they don’t come out.
6 Push the pins through by hand,really easy
7 Then i put where the drilled holes are on the edge of a vice and tapped the pins the last couple of mm so they bite in to the mech using the 1.5mm drill bit drift (sink them 1mm below the surface as this is where they should be).
Job done..:)
