Engine Identification The model name provides the following data: L 10 –310 E Electronic Fuel System Brake Horsepower Displacement (Liters) Engine Model Designation Engine Dataplate The engine dataplate is located on the fuel pump side of the rocker housing. The engine dataplate provides model identification as well as other important information about the engine. 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. 1. Engine Serial Number (E.S.N.) 2. Control Parts List (CPL) 3. Model 4. Horsepower and RPM Rating Engine Identification L10 Page 1

Fuel Pump Dataplate On STC and Fixed Time engines, the fuel pump dataplate is located on the top of the fuel pump. It provides information for fuel pump calibration. ECM Dataplate(s) On CELECT™ engines, there are two dataplates on the top of the electronic control module (ECM). The dataplate on the left contains the part number (P/N), serial number (S/N) and the data code (D/C) of the ECM. The dataplate on the right contains the engine calibration information.

Specifications - General Information The specifications in this manual are organized in the same sequence as the L10 Series Engine Shop Manual, External Damper Models, Bulletin No. 3810476. The minimum and maximum tolerance limit specifications are listed in both metric and U.S. Customary dimensions. The metric dimension is given first, followed by the U.S. Customary dimension in brackets; for example: 0.50 mm [0.020 inch]. The assembly and rebuild specifications and torque values are provided to be sure the parts are assembled correctly, fit properly, and are secured with the correct torque value. Most of the capscrews used to assemble the L10 engine are metric. Some components, such as the air compressor and the fuel pump, are installed using U.S. Customary capscrews. Capscrew torque values are listed in newton metres and foot pounds, unless otherwise specified. If a torque value is not listed, use the standard torque value for the capscrew. Refer to the Table of Contents, Capscrew Markings and Torque Values, in this manual. Specifications - General Information L10 Page 5
