I'll try to post this from my phone. Not sure how well it will work...
The trick will be whether you can remove the 6 top screws.
First remove the switching unit cover. Be careful with the gasket!

Then the 6 top screws

You'll probably see a bit more grease built up at the top of the paddle swing on both sides. This one is very dry.
(Picture 3 and 4)
If it's dry, add some grease. Just smear a light coat all over the inside until the paddle has what you think is enough resistance. If there's enough already, just use it instead.
Last picture, the top gasket. Also something to be careful with.
Have fun! Let us know how it goes.
