Change Summary Due to manufacturing capability and limitations, CES is proposing a change to the inlet Mounting Zone edge location and profile tolerance. Remove the profile tolerance callout completely Change the “tube inlet to heat shield edge” dimension to specify a maximum dimension (see slides 3 to 6 for print detail). The change is to be implemented via deviation until P-phase prints are available with the above dimensions. Configurations Impacted: All EPA2017 Horizontal HD and MD systems. Expected Installation Impact to OEMs: Minor to none.
