Breville Coffee Grinder Improved Main Gear, part number SP0103055. Previous part number SP0100119.

This is a new gear from Breville that is made of an improved material which should help resist gear stripping.

This gear is backward compatible with all old grinders.

Please see my instructional video here to assist with gear replacement. This does not cover full machine disassembly, just the work on the grinder unit itself: https://youtu.be/oOZBiQBCFjU
