Thread: Noisy AMK Compressor

You can also pull the insulating sponge out of that cover, I've had mine done and can't say that I've noticed it sounding any noisier when running from inside the car. Although yours looks as if half is missing anyway, might be different to my Hitachi vs AMK.

The insulation is only installed to the front half of the cover. It is easy to clean with a hose and a dry in the sun for awhile.
