Bunn Commercial Grinder Burr Kit – Burrs & Mounting Screws Complete burr set for Bunn's commercial grinder lineup, including both burrs and the mounting screws so there's nothing extra to source. This is the fix once burrs have worn past the point where a finer grind setting still gets you there. COMPATIBILITY Fits: Bunn DG2, G1, G2, G3, G9, G9T, G92S, G92T, G92COMBO, LPG1, LPG2, MHG, WDG2 INSTALLATION Technician-recommended - requires grinder disassembly and a grind-gap recalibration after the new burrs go in. PRO TIPS Espresso Parts offers valuable guidance on maintaining your grinder burrs, including when to replace them and how to go about changing your coffee burrs. Worn burrs usually show up as creeping grind time at the same dial setting and more fines/static at the doser - not necessarily a change in taste. If you find yourself dialing progressively finer just to hit your old shot time, that's the burrs talking, not the beans. Always replace both burrs together, never just one - mismatched wear between an old and new burr throws off the gap geometry and grind consistency will suffer even with a fresh calibration.
