RED & GRN are fundamentally identical. The only improvement the GRN has is a foamed plastic seal around the motor's output shaft occupying the narrow gap between motor and brushes gear-cases -- a very important addition. Some BLK decks have that seal too. vic7767 can add that seal to a CHM re-build.

The robot might go into the 'reman" process, but the BLK CHM will be trashed or re-cycle-disseminated. IMO, iRobot
wants to erase all evidence that they (iRobot
's bean counters) made such a gross mistake by not paying attention to what engineering people told them must be done to achieve a working CHM using sealed ball-bearings.
There a way to get the debris out of the bearings? I'm trying to pick it out with tweezers and a pin and not getting very far.
You will not succeed by doing that. I gather you have not read the linked thread that I posted for you. There are ways to clean those bearings, but after you spend the required effort doing the work, you still have un-sealed bearings, they won't be as clean as when first mfd, and their balls and grooves will have been damaged by pulverized grit (silica dust); and if you consider time spent as having any monetary value you will have spent more than the cost of a pair of replacement sealed bearings
