The complete gearbox kit found installed in the new-model Baratza Encore, Virtuoso & Virtuoso Preciso grinders employing the Baratza M2 Burr Set (SKU 5190).
This kit is needed to retrofit previous-model Baratza Virtuoso & older-model Maestro & Maestro Plus grinders that need the main drive gear replaced. No installation instructions are provided, so take your time if you decide to undertake this repair yourself.
Note: if your grinder employs the older-style motor (5205), then you'd have to install both a new motor (1058) & powerboard (SKU 5204) to install this kit. In this case, it's perhaps wiser to acquire a new grinder.
If you're unsure of the motor you have, please send a photo of your motor in an email to Service@espressotec.com, we'll make sure to let you know which motor it is and whether or not additional components are needed.
