PROBLEM

Show/hide table

The machine attachment configuration setting for engine fan type needs to be set to "viscous clutch" on certain 320D and 320DL Excavators. The machine configuration might be set to "direct drive" on those machines. Leaving the configuration at "direct drive" can lead to potential overcooling, reduced fan drive life, and noise/fuel consumption complaints.
