How to remove burr from Isomac grinder (Nemox/Lelit/Quamar)

#1: Post by **uglykidwen** » October 16th, 2015, 8:22 pm

I have a Isomac Professonale for years.

Thinking the burr need to be placed.

Got one set from internet but stuck in how to remove the top part of this burr set.

Searching around but no information so far.

I wonder if any people here has some experience?

Should be the same in Nemox/Lelit/Quamar grinder.

Cheers

The nut which holds the top burr in place has a left hand thread. You would turn CLOCKWISE to loosen and thus COUNTER-CLOCKWISE to tighten.

I wrote this over 10 years ago, but it's still relevant.

"Remove the bean hopper and the spout, remove the top burr, the lever
and the spring (don't lose the spring!)

Use grips to hold the bottom burr still and undo the 10mm nut holding it
on. IMPORTANT! THIS NUT IS REVERSE THREADED! IT UNSCREWS CLOCKWISE!
Remove washer, burr and sweep."

Thanks a lot, Alan and Erics,

However, I have replaced the burr, the only thing I can not take off is the top part, which looks like the photo.

I have used the pliers but it did not move. And I was also worried if I will damage it.

cheers

Maybe this will help: Trouble replacing burrs of LeLit PL53 - Help! .

That upper burr carrier needs to be soaked in coffee detergent and cleaned and I would be a little hesitant about putting any parts in a vice.

The upper burr is a friction fit in the plastic carrier. Position it over something that supports the carrier but doesn't touch the burr, then use a screwdriver and a hammer to slowly go around the little protruding bits and tap it out of the carrier.
