on mine, this was a freshy from Kenna, I just got it this afternoon as a replacement. it was actually pretty easy/peasy… 6-3mm flat-head hex screws, the screws were tight, but NOT lock-tighted, I simply used a 2mm hex wrench titanium coated hex driver and loosened them all up, and then backed the screws out in a star pattern.
As I got near the end, the motor can end “popped open” In one pick above you can see a wavy (spring-washer) between two thrust washers. I then took out a nut driver roughly equal, however smaller, in diameter as the front (drive-side) bearing and slowly pressed the center section, stator and bearings from the can.
When I could get a hand around the stator, I just pulled it out… pretty easy, assembly wasn’t much more difficult.
Let me know if ya need anything else!
