system. The new design features a plate crab which extends the retorqueing interval from 12 to 36 months. Retained in this new model is the rocking pin piston. The rock- ing pin design incorporates mul- tiple wrist pin surfaces sepa- rated by an eccentricity. This provides increased load bearing capacity for the higher peak fir- ing pressures associated with improved fuel efficiency. As with past EMD engine de- signs, this new model has been developed with retrofitability in mind. As a result, most turbo- charged 645 models now in the field can be upgraded to take ad- vantage of these fuel economy improvements.
