This video demonstrates how to replace a brokenfolding wing mirror gear on 2011 Ge8 Honda Fit/Jazz Plastic mirror gear circumference is 40MM Metal gear rod length is 30MmM
Thanks for this. With mine the cog was split on one side only. I tried epoxying it back together (and infilling the internal gaps) and replacing, which worked once but presumably resplit and back to square one. Have 3d printed some new cogs as there are a number of templates available for free online, but given it takes so long to replace, and you need to fully re-assemble before you can actually test the change, I'm hesitant to try again.
Very good video with clear and instructions with the parts numbers highlighted. My wife's Honda Jazz side motor driver side died yesterday. Thank you for sharing.
