Eureka 75mm burrs

I purchased a Eureka Olympus 75 from a cafe a little less than a year ago. It came with red speed burrs and has accumulated about 20,600 shots on the shot counter over its life so far (the vast majority of which was in the cafe).
If I assume 20g per shot, that works out to about 900lbs of coffee through the grinder. For the red speed burrs, if I recall correctly, that is about half of its lifetime?
The past week or so I have had to tighten up the grind and increase the time of grinding in order to maintain a consistent flow rate. So I am wondering if maybe it is time to replace the burrs even though my calculation (and assumption) is that there should be significant life left. Thoughts?
Supppose I did want to replace the burrs. Does anyone in the US have them in stock? As far as I can tell there are none available.
Regards,
Justin

Start by removing burrs cleaning including carrier and inspecting cutting edges for sharpness and damage if any from pebbles etc.
Between order and chaos there is espresso.

Seconded ^
Clean burrs first and make sure everything is aligned and if still after that you feel like the grinds aren't coming out correct then explore dropping money on burrs

If you do need new burrs try to get the 75mm TiN Mythos burrs as they're great and fit the Olympus. I've owned and Olympus for years with those burrs and they give great results.

Um, same coffee?fizguy wrote:The past week or so I have had to tighten up the grind and increase the time of grinding in order to maintain a consistent flow rate.
As coffee ages, the beans soften, and there are less fines, You'll need to tighten the grind to get the same flow at the same dose. You will also notice the taste go flat. Generally it's far better to up dose than to tighten the grind as coffee ages.

Thanks Jim, this is true and a good point.
I roast a couple times a week and I have never observed this trend in the year I have owned this grinder, which is why I was thinking it could be the burrs.

I think you should do a thorogh cleaning before changing burrs.
IMO burrs aren't likely to be worn out that easily.
