1. Remove EXP-PST-1 and MANF-6 specs callout from outline drawings Affected Part Numbers: All TLAs Reason for Change: Print correction Anticipated OEM Impact: None Cummins Restricted

2. Nomenclature revisions in Outline Prints Affected Part Numbers: All TLAs Reason for Change: Print correction Anticipated OEM Impact: None Corrections will be made for all three engine platforms (B6.7N, L9N and ISX12N 2018 L9N Cummins Restricted

3. Rib added at the middle portion of Upper and Lower Heat Shield for all L9N TLA prints Affected Part Numbers: All L9N TLAs Reason for Change: Strengthen heat shield Anticipated OEM Impact: None Inlet Rib added to the middle portion of both Upper and Lower Heat Shields used on all P-Phase L9N TLA systems. Cummins Restricted

4. Lift Hook weld length from 50mm to min 30mm Affected Part Numbers: All TLAs Reason for Change: Commonization of manufacturing processes Anticipated OEM Impact: None Min 30mm Cummins Restricted

5. Weld Location change between heat shield and outer body to the outlet end of aftertreatment. Affected Part Numbers: All TLAs Reason for Change: Increase inlet mounting zone Anticipated OEM Impact: None Exhaust Gas Inlet Weld will be moved to this location. Cummins Restricted

6. Remove lip feature from the heatshield at inlet. Affected Part Numbers: Select TLAs Reason for Change: Feature previously assisted in ensuring mounting straps did not overlap top of welds. Due to weld location change (see Change 5), this feature no longer serves that purpose. The heatshield now acts as the locating feature and the mounting zone has increased. Anticipated OEM Impact: None Exhaust Gas Inlet Cummins Restricted

7. Temperature connector color will be etched on the Heat Shield at below mentioned location. Color combinations for connectors for different platforms are as mentioned in below table. Example ISL system image Affected Part Numbers: All TLAs Reason for Change: Ensure correct temp sensors are installed during assembly and service events Anticipated OEM Impact: None Exhaust Gas Inlet Brown Black Description Mid Bed Temp Connector color Outlet Temp Connector color L9N Canary Key C: Brown Key A: Black ISX12N Canary Key B: Light Grey B6.7N Canary Cummins Restricted
