In my case, I found one strange object, sticked on the gear wall. Look like it is a washer pressed with gear teethes. Good to take it out but I wonder where it came from?

Unscrew this, remember follow the clock wise

If you just want to replace worn out impeller: hold the limiter steady, unscrew (red square) with clock wise, take out the inner burr. And try to clean and replace the impeller while holding the limiter! You should ask some body to help with this step.

Take the Limiter out. Take care because it go with 6 balls and 6 springs! Perform this step only if you think there are some wrong with the Limiter (Big crack sound when grind )

Hi, could you please tell me from where can I buy Breville BCG820BSS1BCA1 gear/limiter, the one which is in step 6. it’ll be big help.
my email is hbk.singhvi@gmail.com
Hello, I need to remove the burr grinder blades. Any suggestions? There isnt a nut at the top of the grinder burr, so, not clear how to get it out.
I have the same issue with removing the lower grinder burr. The 860 doesn’t have a nut on top like other models and appears to be screwed on to the main motor shaft. Since I’m needing to replace the lower impeller I need to take it off the motor. I’ve searched high and low on the internet for any instructions, but can’t find any. I’ve tried unscrewing it, clockwise and counter-clockwise, but it just turns the motor. Really scratching my head on this one!
Sorry for late reply, I hope you found the way long time a go :-) If not, please go to Step 6.

I'm stuck with the same problem. It looks like from the pictures on this site that sells replacement impellers that the whole shaft is removed with the Burr attached, not just the burr: https://www.shapeways.com/product/52W3D2...
Not sure how they did that though, it looks like there might be some flat surfaces at the bottom of the shaft that could be gripped by a wrench, perhaps it just pull out with force applied to the bottom of the burr?
I found this while reading step six above more carefully, it sounds like there is a nut at the bottom that unscrews from the shaft that the burr is attached to so that the whole shaft can be removed to replace the impeller. I’m guessing that you could use a marker to mark the position of the limiter instead of having someone else hold it. What a PITA.
“If you just want to replace worn out impeller: hold the limiter steady, unscrew (red square) with clock wise, take out the inner burr. And try to clean and replace the impeller while holding the limiter! You should ask some body to help with this step.”
Yes, you are right, go to step 6 if you want to replace inner burr.
And no, position of the limiter is not a problem. The problem is the limiter contain balls and springs, they are on top each other and easily collapse if you not hold it strong…

Once the limiter the nut back on the shaft and torqued, should I be easily capable or rotating the gears? I seems to have quite the resistance there now… :S
Thanks for the breakdown. I was able to see how to change the gear, under the grind-adjust dial and move it a couple of teeth to adjust the limit on the height of the minimum burr setting. I don’t think I’ll have to do it again, as it’s been about eight or ten years before the minimum grind setting was too coarse for a good extraction. It grinds fine on setting “3” for now.
