(1) New repower engine
(2) Reman repower engineThis Special Instruction does not include procedures that can be found in your existing manuals. Refer to the original Service Manual, Parts Manual, and Operation and Maintenance Manual for more information.When you have completed this procedure, prepare the machine for service. Refer to the Operation and Maintenance Manual.Note: Do not perform any procedure in this Special Instruction until the information has been read and understood.Reference: Service Manual, Parts Manual, Operation and Maintenance Manual.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.Register the Retrofit
When performing a retrofit installation, record the vital information in Table 2.Note: If the procedure is performed by the customer, ask the customer to record the proper 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 2 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".

Do not attempt to assemble this machine until you read and you understand the assembly instructions.Improper assembly procedures could result in injury or death.
Personal injury or death can result from improper lifting or blocking.When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component.Approximate weights of the components are shown. Clean all surfaces where parts are to be installed.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.

Proper welding procedures are necessary to avoid damage to electronic controls. Perform welding on the engine according to the following procedure.
Set the engine control to the "STOP" mode.
Turn OFF the fuel supply to the engine.
Disconnect the negative terminal from the battery.
Disconnect the engine electronic components from the wiring harnesses: ECM, throttle actuator, actuator for the turbocharger compressor bypass, fuel metering valve, and sensors.
Protect the wiring harnesses from welding debris and/or from welding spatter.
