belt noise

[chris989]

I found the issue after ~1000 of wasted $$ and time.

I removed the OBA compressor from LittleshopMFG and presto, noise gone. york210 is new and the fabricate nice brackets but something is a miss. Everything was perfectly aligned and when i call for OBA it works perfect. When the engine is running and not calling for AC it is perfect. Only when it called for AC and running a ~111" belt around the York OBA did it create the harmonics.

Crazy enough,, under the hood, everything sounded smooth,,, no noise, no vibration but apparently harmonics and acoustics are fickle. Like the drone of my 40 series flowmaster on a different build.

I am kicking myself for not taking it off sooner. I am confident when i contact LittleshopMFG they will have "never heard of it" and "never had an issue".

The clutch on the york appears perfect and spins freely so i do not know if getting another would make a difference. I doubt any of it is returnable.

I hope this thread saves someone in the future.
