Left hand/front derailleur shifter, XT Sl M770 for reference, was getting ridiculously stiff. So I’ve tried to free it up, previously with lube which did little. Then I figured it’s probably gunked up so I try it with some degreaser. Which has duly done it’s job but also done something else in the process as the ratchet’s no longer locking/biting in the internal mechanism. I’ve tried to disassemble to see if I can fix it but can only get it about half way there. In the process I’ve looked for the traditional exploded diagram on Shimano tech docs. To help see how it’s all held together but that’s not proving to be particularly useful either as it only shows the external fittings not a full exploded view.
So with all of the above in mind can anyone please help me out with any of the following answers –
1. A full exploded diagram of the internals, which will show me how to take it fully appart.
2. A youtube link with a video showing how to do it.
3. The trick to getting it fully appart.
I’ve tried googling for the above but clearly my googlejitsu is poor as all I’m getting are links to the second rate tech docs like this!
