Another guide, now for the RX100 STIs. These were in lovely condition, and its obvious they did not get much use over the years. However, the left hand shifter did not click at all. Right hand was quite stiff when clicking. Obvious signs of the gummed up grease.
RX100 levers are not symmetrical. The right side lever is different to the left side lever. So I will be going through both left and right sides in this guide.
This is the right lever. Remove the hood, and use a 2mm allen key to remove this grab screw. It does have a little bit of threadlock, so it may be a little hard to unscrew.
Use the same hex key to push out the pivot. Now you can take the lever away from the body.
Next, use a 5mm hex key to remove the screw holding on the name plate. Make sure youre holding onto both the name plate and the lever when unscrewing.
You will be greeted with this spring. This is different to the assembly of the new Sora(3300) and 105(5500) levers. Id say its much more easy to dismantle and rebuild because the spring is here.
Now flip to the back side of the lever. Push the smaller lever over so the screw is visible. Unscrew with a small Phillips, and watch out for the small washer underneath.
Now, just pull the lever right off. No springs underneath like on the new levers, so its very simple.
Very simple. The internal gears have been reached, and now you can ahead with cleaning it. I am using fuel, but you can use your degreaser, or whatever youd like.
Silly me forgot to take pics of when it was all clean. Oh well, you can find the pawls, and grease those areas up.
