yes, i removed the speedo cable first. then it is easier to yank that gear out.
i don't remember clearly how it looked like, but i do remember the white plastic gear wheel.
if you go to the website of autozone, they have uploaded the chilton's guide and there is a picture of this this thing there. it is not a photo but a sketch of the gear.
you can see it at
