Because retrofits to a prime product will change the configuration of the product, updating the configuration in SIMSi and AIMS is important. If the retrofit information is not provided, Caterpillar will not be able to provide important product updates.The following information includes instructions on registering the updates and retrofits.
When performing a retrofit installation, record the vital information in Table 1. Note: If the procedure is performed by the customer, ask the customer to record the proper information.Note: When registering this upgrade, use 381-0874 Engine Conversion Ar for the part number to be registered.

( 1 ) Only applies if a component is replaced by a retrofit component. If the product is an engine, and the product retrofit is a kit for upgrading the engine, disregard the "Removed Component" information. Refer to detailed instructions in Step 3 for more information.
( 2 ) Record the highest level retrofit kit, arrangement, or group part number.
( 3 ) Most retrofits will not have a serial number. Exceptions include emissions repower engines and diesel particulate filters.
Update the product configuration by entering the information from Table 1 into SIMSi and AIMS.Note: For retrofits that have a Caterpillar serial number, the AIMS application is "JIZ111-08". For retrofits that do not have a Caterpillar serial number, the AIMS application is "JIZ111-07".
For detailed instructions on updating the product configuration, refer to Special Instruction, REHS5097, "Instructions to Register the Retrofit".
