Carbide Compact Router Screeching on Startup

[mhotchin (Michael Hotchin)]

Sounds like you have a bad bearing. Does the casing heat up right where the shaft enters the body?

Some people have changed the bottom bearing on the router, so it’s doable.

Shapeoko pro router

Makita and the C3D router (a clone of Makita) both have bearing problems. They do sell kits to rebuild them. With 2 spares you could rebuild them and have spares. The bearing is only $7.10. Of course you have to disassemble the router but it is less than buying a new one when the warranty runs out.
