The engine dataplate shows specific facts about your engine. The dataplate is typically located on the engine rocker cover, but may be located on the side of the gear housing. The engine serial number (ESN) and control parts list (CPL) provide data for ordering parts and service. The engine dataplate must not be changed unless approved by Cummins Inc. Have the following engine data available when communicating with a Cummins® Authorized Repair Location. The information on the dataplate is mandatory when sourcing service parts.



Note : The engines covered by this manual are produced worldwide. The dataplates used on engines can differ in appearance and location of information. The following illustrations show examples of common dataplates used and the information contained on the dataplate.

3. Horsepower and rpm rating. If the engine dataplate (1) is not readable, the engine serial number (2) can be identified. The engine serial number location varies by engine plant. Check the engine block on top of the lubricating oil cooler housing. The engine serial number could also be located at the front face of the engine block. Additional engine information is available by reading the engine control module (ECM) dataplate.



Marine Applications



The engine dataplate provides important information about the engine. The engine serial number (ESN) and control part list (CPL) provide information for service and for ordering parts. The engine dataplate must not be changed unless approved be changed unless approved by Cummins Inc.

CM840/CM850 (CM2850)/CM2100 ECM



The ECM dataplate shows information about the ECM and how the ECM was programmed. The dataplate is located on the ECM. The following information is available on the ECM dataplate: • • • • •



ECM part number (PN) ECM serial number (SN) ECM date code (DC) ESN ECM code: Identifies the software in the ECM.



Note : Have the ECM code for your engine available when communicating with a Cummins® Authorized Repair Location.



Note : The presence of an ECM dataplate depends on the manufacturing plant and the date the engine was manufactured. If an ECM dataplate was not installed by the manufacturing plant, calibration data can be found on the engine dataplate. Marine Applications
