The dirty environment extended to the fuel as well. Clogged injector nozzles was a common industry problem due to inadequate filtering, poorly refined fuel and carbon buildup. On top of that, the injection system of the F, which worked very well in stationary and marine applications, was ill-suited to the operational environment of a power shovel, which varied from a massive load that badly lugged the engine, to running at peak rpms with little load. The injection system didn’t have the flexibility necessary and tended to overfuel during those heavily loaded periods, causing further durability issues.
