So I received the silicone lube earlier than I thought.

I tried it over and over, nothing happened. I even tried to rotate the thing with some multigrip pliers, it wouldn't obey.

The only thing that I noticed was that some brownish powder was coming out. That could have only ment one thing: rust

Then I decided to crack the damn thing open, using those pliers and here are the pics:

Rust, rust and rust everywhere. It's amazing how much rust it generated after only 10 days. I took a can of WD40 (I read somewhere that it wouldn't harm the plastics too much), and I applied some on the metal frame. I couldn't get it out of the plastic thing, that's how much damaged it was.

In my opinion, the frame moves with the second thing on the second picture as there are grooves on it. and it rotates inside the plastic thing in pic one. 

^_^ I couldn't find a better name than "thing" to describe those plastic parts. Sorry.

Maybe I'll give you some more info later tonight as the wd40 start to pay off.

I learnt one thing though, and I hope it will help idiots like me who tried or will try to wash their plastics:

DO NOT EVER IMMERSE THE CLUTCH MECHANISM OF THE MACINTOSH PORTABLE IN WATER. 

Physics 101 bis: IRON + WATER = RUST  :)
