Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If other boring/drilling machinery parts
Engines shipped as integral rig components classify with the drilling equipment.
If reciprocating positive displacement pumps
Pump-driver engine assemblies often follow pump classification.
If over 75 kVA generating sets
Large power gen sets supersede engine-alone classification.
