SCN60PA Scotsmen ice machine loud noise after 45 minutes of production of ice.

[TylerOrton]

I have a Scotsmen ice machine model: SCN60PA-1SU serial #15121320015217

I did a cleaning of the machine. It had this (screaming noise) I have already replaced the gear box and the water seal and bearing. And then did another cleaning. And it will work just fine for a good hour or so and then start the same scream like noise.

Did you ever figure out what the issue was?
