The rotor of an induction motor is filled with shorted

Is that a problem that you would characterize as economically
repairable on a 5 hp motor?

I have had experience with a motor with a bad squirrel cage ! It ran a
little rough and was way down in torque. It also got a lot hotter than
it normally did.

I tried to solder the copper bars, two of them, where they had cracked
at the end. A waste of time ! A new rotor cured the problem, curtesy
of Brook Motors.
