Gear Case W10572193

Requires some tools and time

You can use Google to find teardown videos and exploded parts diagrams. Disassembly required an assortment of non-standard screwdriver bits (like square bits), hole punches, plastic tools like those used on cell phones (to avoid gouging painted aluminum parts)... and for me a drill. One of the pins that I had to remove wouldn't budge after some serious blows with a hammer, so I drilled it out part way. Then it released.The inside holds a ton of grease, so have paper towels handy.
