Haruki,
Some of the above stuff, like gluing in the endbell bushing, is just a preventative measure.
We race this motor quite a bit in hardbody racing, and I don't ever remember seeing any issues with the can bearing where it would make sense to solder it in.
The magnet issue might be a more recent phenomena. I've seen it once before with motor in hardbodies, and it just happened to me Wednesday night, while going to install a motor in a wing car.
It must be a semi-regular occurrence, as when someone mentioned it on OWH recently, they got a quick response, with a fix using snap ring pliers. I stopped by my local Harbor Freight yesterday and picked up a pair for $3.99. Hopefully. I'll be able to fix it.
FWIW, I had at least one or two Puppy Dog bag motors with the rubbing magnet issue.
