should be used for the upfit). Please refer to service procedure 011-036 in the appropriate
Cummins service manuals.

Note : Using permanent paint, write "C2635" on the new SCR's can such that it is
visible after installation.

B6.7 AND L9 MY22 SCR EMISSIONS CAMPAIGN

Note : Certified repair locations outside of California, who elect to perform this
campaign on engines installed in vehicles which are registered in the state of
California, are authorized to do so if they have the two items noted below in their
inventory. Please note that the Label, Authorized Change and the Proof of
Correction Form must be ordered through standard parts processes. They
are not available on QuickServe® Online.
2. Applicable to all engines, including those registered in the state of California, a "Label
Authorized Change", Cummins part number 5297400, must be filled out and affixed to the
engine. Clearly print or type "SCR UPDATE" in the center box. Fill in the Campaign Number,
Distributor or Dealer Code, and Date information. Peel off the backing material and install the
label on the engine valve cover near the engine data plate. There is a clear protective cover
on this label; peel the backing off of this cover and push the clear cover over the printed
material. This will help protect the label during engine operation. Label cost and appropriate
SRT time can be claimed per Campaign guidelines.
3. Applicable only for engines registered in the state of California, an "Emissions Campaign Proof of Correction" form, Bulletin # 4310621, must be filled out and provided to the
Customer. Inform the Customer to retain this certificate as proof that the Emissions Campaign
has been performed. This form may be required as proof of an Emissions Campaign by the
State of California, for vehicles registered in that state, the next time the vehicle registration is
renewed. Form cost and appropriate SRT time can be claimed per the Campaign guidelines.
4. File one claim for the listed parts and required labor associated with this repair.

Material Disposition
Where applicable, items removed should be returned to ReCon for core credit. Unless otherwise
indicated, items with no core liability can be scrapped.

Reimbursements
