Im restoring a Bezzera BB95 grinder that appears to have been cleaned never. It smells like a dogs bum. Actually slightly worse I think.
Ive managed to pull apart the doser and give it a good scrub out (including removing a spiders nest and some dead cockies).
For the grinder itself I think I need to remove the burr assembly from the drive shaft, as shining a torch up the chute I can see lots of coffee tar on the underside of the brass thingamy. After scraping as much crap as possible off its still pretty gross.
The three screws holding the burr came out easy enough, but it wont budge. Not sure if its just a tight fit, or if the tar has glued it in. What Id like to do is remove the entire brass do-hickey as well. I can see that its threaded on but how do you unscrew it? I cant find an easy way to prevent the motor shaft turning.
My next attack will be to pull the cover off completely but I thought Id ask first if that were necessary. Ive included a hopeless phone-cam shot showing the burr assembly with the 3 screws removed. Inside the brass bit sticking up in the centre you can see that its threaded onto the drive shaft.
