Recommended tool
If you are looking for the tool to easily remove the spring pin holding the gear in place be sure to check the option above to add the 5/32" roll pin tool. It is the best tool to easily remove the pin without damage. It also reduces the chance for injury when driving out the gear with improper tools.Reminder to always wear safety glasses when using striking tools.The Large white gear is 2 3/4" x 1/2" wide, with a 1/2" bore. The worm gear is 1 1/8" OD, and the teeth are 1 1/4" wide. Sizes are approximate.

Great Video
I watched the video and saw how easy it was to replace my gear. I received the part in about 2 days and had my door opener working in about 45 minutes.
