  4. Examine the gear. 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?

  5. 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 )

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?
