Video of GB 2.0 installation

October 23, 2012

At the beginning of 2012 we introduced the 2nd generation gearbox (GB 2.0) for our conical burr grinders. All new grinders manufactured since January have the new gearbox. At the same time, we developed a parts kit to upgrade the gear box of Baratza conical burr grinders manufactured before 2012. A LOT of people are upgrading their grinders to the new gear box. We felt that the response warranted an installation “how-to” video, in addition to our installation guidelines, already in our troubleshooting section, so here it is!

Upgrade kit for Baratza gearbox 2.0

In case you are not familiar with the GB 2.0, here are the highlights!
With GB 2.0, we significantly increased the strength and durability of the drive transmission while decreasing noise. In addition to a new drive shaft, motor mounting plate and bushings, this change included a new drive gear made of 15% glass filled thermo plastic which is quieter than the prior metal gear, wears better and is more shock resistant. We tested it by throwing stainless screws into the burrs, and in every case the motor/gear/burrs stopped dead and the (automatically-resettable) thermal cutout was triggered and the gears were fine.

The upgrade kit is available through our webstore GB 2.0 rebuild kit
