On some older domestic USA motors, the manufacturer may have used cast end
end bells for the motor end plates that are very similar for both sleeve and
ball bearing models.
For the ball bearing models, they eliminate the extra material used for the
sleeve model, and machine a counterbore/pocket for the ball bearing
assembly.
This means that if a HSM discovers a good motor with worn sleeve bearings,
he can sometimes machine away the sleeve support webs in the end bell
castings to install ball bearings....

Thanks, I'll watch for that.
