Thanks. This was a useful video. I had cleaned my Krups blade grinder with a wet paper towel and a bit of water must have got into the top bearing. When Ii tried to use it a week later, it was seized up. I guess the water had combined with coffee dust to make a paste which seeped into the top bearing and dried to prevent it from turning. This video, and it's companion video, enabled me to open the top and bottom of the grinder, remove the blade, clean out the top bearing with a dental pick (you can use a pin), free it up, and lubricate it. - Note, where the vlogger used a fine hot air blower, I just aimed a hot hair blow-dryer into each of the bottom holes, pried away the bottom with a screwdriver, and the bottom came free -- the hot air is the key, to getting it off - I then put two drops of machine oil on the top bearing, got it to turn fairly free (it's normal for it have a bit of smooth resistance), and reassembled the unit. I used clear postal mailing tape, trimmed with scissors, to hold the bottom on. It now works like new, and I now know how to renew the unit / free the bearing if it ever seizes up again. $25 saved! 👍 - (Bonus -- while searching for this video, I encountered another video that shows how to get a better, more uniform grind from a blade grinder, resembling that from a burr grinder: pulse-grind the beans 2 seconds at a time; hold the unit shaking it gently while grinding; feel the granularity with your fingers til it feels the way you want it (should feel like fine sand); avoid creating dust This will minimize the formation of fine dust and give you a more uniform granular grind rresulting in better extraction.. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-bYS4tW-yn4k.html ) -
Thank you, helpful video. But when you show close up of the brushes, your hands were beyond the scope of the camera lens so we couldn’t see the brushes.
If you look, there is a slot in the bottom of the plastic cover (under the label) that allows a small flat-head screwdriver to engage the slot in the motor shaft from the base. This allows one to hold the motor shaft while turning the cutting blade on the other end so that it can be removed. To get the metal cup off the motor shaft I used compressed air at aimed at the motor shaft and it popped the cup out. This allowed access to the two screws that hold the motor but don't remove them until you have taken the bottom off if that is what you plan to do. I just put some oil on this end of the motor shaft and hope that it will find its way down to where it needs lube.
That was a nice video, very clear with instructions. Thank you! -. But, that music in the background was so unnecessary, so annoying and distracted from what you were trying to say. If you watch it, you will know what I mean. Try not to put irritating soundtracks, which spoil an otherwise excellent video. Thank you and best wishes.
