Since my last post, I have dis-assembled the grinder and tore down the motor and grind chamber. At some point this grinder was exposed to water, so I have had some de-rusting to do. The first step was to remove the grind adjust/grind chamber cap to access the burrs. Here are a couple of shots of the grind adjust assembly. This was rusted solid and took some effort to clean up and get working again. It's interesting to note that the thrust bearing for the adjustable burr is a plug of hardwood.
Removing the adjustable burr assembly required a week long soak with PB-Blaster and some gentle persuasion with a long pry bar. I have been very careful to take my time and not force anything. There are no replacement parts available unless a parts unit is located. Here are some shots of the adjustable burr assembly, feed auger and wiper.
Here's what they look like cleaned up.
Next, I will separate the grind chamber from the motor, remove the fixed burr and replace the motor bearings. Lot's more work to do before we can grind some coffee.
