GB 2.0 Upgrade Kit & Video Tutorial Guide

February 27, 2014

Baratza is always striving to improve, from the time we manufactured our first grinder, to right now. The stripped drive gear issue is generally caused by a rock fragment or unroasted bean getting caught between the burrs, causing the motor shaft to chew a few teeth off of the drive gear. The GB2.0, introduced into our new grinders in 2012, prevents this mechanical issue from occurring. With the GB2.0, if a hard object is to get between the burrs, the thermal overload fuse will cut power to the motor until the jam is cleared.

GB2.0 installation requires full disassembly of the gearbox, so we decided to make a thorough video to encourage users to do the repair process at home.

By design, Baratza has created a grinder that can be easily serviced either by our customer or our technicians via the Grinder Repair Program.  We strive to make all parts available for our machines, along with installation instructions.  This allows our users to keep even our earliest model grinders in operation rather than discarding and replacing them, reaffirming our long standing goal of keeping grinders on counter tops, and out of landfills.

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.
