Harmony II HRT216 Change Cable replacement? Please help...

Hello all,
I am working on a Honda Harmony II HRT216 TDA. I have to replace all the cables...the clutch cable, throttle cable seems to be pretty easy to replace but after looking at the Change Cable, it appears you have to take out two Phillips screws UNDER the transmission pulley! So, I assume you have to take the pulley off to do this. Can I assume you have to get a thin drift to drive the pin out of the pulley to take it off? I'm trying not to remove the tranny and it seems like this could be possible without doing that. Any suggestions out there? Thank you...

Guess no one has ever replaced the change cable before on a Harmony!? lol Anyway, i was able to drive the pin out of the pulley and pull it off without pulling the tranny...should be able to get the two phillip screws out so I can change out the cable now...thanks anyway!
