It's probably fine, but if I were going to rely on it for heat, I would probably open it up and re-soak the bushings in engine oil.

It's been a long time (no heater in the last two TRs), but I don't recall anything being particularly tricky.  Like most motors, there are some wires that you have to be careful not to over-stretch while disassembling the motor.  Long time ago, I even re-wound one successfully.  

Well, at least the motor ran faster afterwards, can't say it really put out any more heat.
