[topsaiilbye]

I have a 325 with 600 hrs.

cant seen to locate it . Short of replacing all 3 pulleys any thoughts on how to locate the guilty one

Pop the belt off, and spin each spindle (assume that is what is meant by "pulley") by hand to listen for grinding, as well as rock (shake) for any sloppiness in the bearings. If a bad bearing, likely will be able to hear it grind.

Also, after running for awhile, shut off and feel each spindle for excessive heat.
