Last head motor noise

[bugdust]

I recently replaced the motor that raises and lowers the head on my LT40. After installing the new motor I've noticed the head reacts much faster, which I like, but the noise has increased when operating the motor, before the old motor was quite. I was wondering if this is normal with the newer replacement motors.

Hello,
  I would remove the belt then run the motor, see if the noise changes. What year is the mill? Can you post a picture? It is hard for someone to describe a noise and tell if it is normal.  :-\

Another possibility could be the end cap is interfering with the plastic fan?

Problem solved! At Marty's suggestion I began removing the belt from the motor and I found the pulley set screw was loose on the the motor shaft. Even though it was tight enough to raise/lower the head it was slipping on the shaft. Tighten set screw and good as new. Thanks for your responses ... thanks Marty.
