Sector Gear Pinion 2081001-8, off 1975 Cessna Cardinal 177RG. Alt 2081001-4. Good condition with some tooth wear on one side. Only half the gears' teeth are used in operation, so the other half of the teeth are perfectly "new". One can swap the L and R pinions or rotate the pinion 180 degrees to engage the unused teeth. See photos for condition. Happy to answer questions you may have.

Sold as is.  Installer determines airworthiness.
