Description of Change: Major power train components now have a sequence number or a serial number. The sequence numbers and serial numbers will improve the tracking of major component life. A sequence number is included on the wheel, the differential carrier, and the spindle housing. A serial number is included on the engine, the transmission, and the torque converter.
The sequence number consists of the month, the year, and the number of the component that was made within that month. This number will identify the "zero" hour on the part and the number will allow the tracking of the machine hours until the dealer replaces the parts during the Planned Component Rebuild (PCR). Various components of the assembly may have different sequence numbers.
Note: The rear wheel station should be identified by the sequence number on the spindle housing.
Note: The 797 PIN: 5YW1-UP
does not use a metal tag on the spindle housing, the differential carrier, or the torque converter. The sequence numbers are a number that is etched into the metal.
Note: Record the serial numbers and the sequence numbers during the machine field assembly.Report the serial numbers and the sequence numbers in the SIMS Report for any claims or repairs that are made to the major power train components. Tracking of the actual hours on the major power train components will be improved. The tracking of the components that are located inside the major power train components is improved. Replacement of the major power train components requires a record of the new serial number or a record of the sequence number that is located on the part. The part that is obtained through the dealer part system or the exchange system might be new or used. The location of the serial numbers and sequence numbers on the different components follows:

Regarding removals, when the removal is a result of a failure of one of the major power train components, the information should be reported in the SIMS Report. Use a standard SIMS Report. Include the normal information, the actual part number that is responsible for the failure, and the actual group number containing part for the part that failed. Use a "R" for Non-DBS Dealers or use an "85" for DBS Dealers for the "Description Code". The serial number or the sequence number of the removed major components should be entered in the first eight spaces of the "Descriptive Comments" field. If the rear wheel station or the differential does not have a factory sequence number, a dealer identification number should be used. Any additional information may be entered in the last eleven spaces of the "descriptive comments" field. Refer to Illustration 15.

When the removal is the result of a Planned Component Replacement (PCR), record the information in a standard SIMS Report. Include the normal information in the report. Include the appropriate SP Number in the "Part Number Responsible" field. Refer to Table 1 for the appropriate SP Numbers. Insert a "U" for Non-DBS Dealers or use a "61" for DBS Dealers in the "Description Code" field. Enter a SMCS Code of 7508 for a Planned Component Replacement or a SMCS Code of 7595 for a General Repair in the "Group Number Containing Part" field. The serial number or the sequence number of the removed major components should be entered in the first eight spaces of the "Descriptive Comments" field. If the rear wheel station or the differential does not have a factory sequence number, a dealer identification number should be used. Any additional information may be entered in the last eleven spaces of the "Descriptive Comments" field. Refer to Illustration 16.
If the removal was the result of a minor repair, the SIMS Report should be used. Include the normal information and the appropriate SP Number in the "Part Number Responsible" field. Use a "G" for Non-DBS Dealers or a "49" for DBS Dealers in the "Description Code" field. Enter a SMCS Code of 7595 in the "Group Number Containing Part" field. The serial number or the sequence number of the removed major components should be entered in the first eight spaces of the "Descriptive Comments" field. If the rear wheel station or the differential does not have a factory sequence number, a dealer identification number should be used. Any additional information may be entered in the last eleven spaces of the "Descriptive Comments" field. Refer to Illustration 16.

Regarding installations, all installations of major powertrain components should be reported on a SIMS Report. Include the normal information and the proper SMCS Code in the "Group Number Containing Part" field. Refer to Table 2 for the correct SMCS Codes. The serial number or the sequence number of the installed major components should be entered in the first eight spaces of the "Descriptive Comments" field. If the rear wheel station or the differential does not have a factory sequence number, a dealer identification number should be used. Any additional information may be entered in the last eleven spaces of the "Descriptive Comments" field. Refer to Illustration 17.
