GENERAL INFORMATION 1. ENGINE IDENTIFICATION Caterpillar engines are identified with Serial Numbers and Arrangement Numbers. In some cases, Modification Numbers are also used. The serial number plate which shows these numbers is mounted on the engine. Caterpillar dealers need this information to determine which components were included on the engine when it was assembled at the factory. This permits accurate identification of replacement part numbers. 2. ORDERING PARTS Quality Caterpillar replacement parts are available from Caterpillar dealers throughout the world. Their parts inventories are up to date and include all parts normally required to protect your investment in Caterpillar Engines. Dealers may offer repair kits or remanufactured parts to allow selection of the most effective repair alternative for a particular situation. When ordering parts, your order should specify the quantity, part number, part name, and the serial number/product identification number of the engine for which the parts are needed. 3. PARTS MANUAL ORGANIZATION Product information in this manual is presented as "information elements" that represent all of the components for the specific model. An Engine Arrangement is an example of an information element. The information elements are organized alphabetically by part name and secondarily by part number within each major section of the manual. 4. TABLE OF CONTENTS A table of contents (TOC) is found at the beginning of the manual. The TOC lists each section of the manual with a complete list of all information elements organized as they appear in the manual. Page numbers are provided for quick reference to detailed parts identification illustrations and serviceable consist lists. 5. MAINTENANCE PARTS INDEX The Maintenance Parts Index, located near the beginning of the manual, references most frequently used maintenance part numbers, providing description, quantity, usage and page number. This information is organized alphabetically by part description. 6. INDEX The index located near the front of the manual is an alphabetical listing of all information elements included in the manual. Page numbers are provided for quick reference to detailed parts identification illustrations and serviceable consist lists. 7. PART NUMBER INDEX A numerical index listing all part numbers and the corresponding page number(s) appears at the back of the manual. 8. CAPTIONS Captions located at the beginning each information element identify the part number and part name along with additional descriptive information. S/N information found in each caption should be used to select correct information for a specific engine. Field replacement options, identification of optional attachment components, and where used ("part of") information is also provided. The first line of a caption is shown in larger type font to indicate the beginning of an information element. Captions for additional pages that may be required to illustrate an information element will be shown in standard type font and will include the term (contd.) . 9. NON-SERVICED PARTS In some instances it is necessary to display non-serviced parts that are a link to lower level serviceable consist lists. These non-serviced part numbers are shown in italic type indicating that they are not available. All consist lists have not been converted to reflect this enhancement. A4 GENERAL INFORMATION SEBP3816-35

GENERAL INFORMATION 10. PARTS LIST REFERENCE NUMBERS Numbers shown in the Ref No column correspond to numbers used in the associated graphic(s). An alphabetic suffix may be added to a reference number to identify lower level consist items. Numbers shown in the Graphic Ref column refer to the graphic number identifier displayed in the lower left corner of each illustration. The Graphic Ref number may be used in combination with the item Ref No to determine the correct part number. There may be intentional omission of a Ref No in a consist list as information is updated to reflect the latest serviceable part numbers. 11. INDENTED PART NAMES When a part name is indented in a parts list, it is part of (included in) the group or assembly under which it is indented. 12. ILLUSTRATION REFERENCE LETTERS When necessary, illustrations contain reference letters (A, B, C etc.) that are intended to track lines and harnesses from one point to another. They are also used to show where to reconnect illustrations that have been separated. 13. ABBREVIATIONS AND SYMBOLS O.D. – Outside Diameter I.D. – Inside Diameter A – Not Part Of This Group B – Use As Required C – Change From Previous Type D – Order By The Meter E – Order By The Centimeter F – Not Shown G – Order By The Inch I – Refer To Hydraulic Information System M – Metric Part R – Remfg Part May Be Available Y – Separate Illustration Z – Not Serviced Separately 14. DESCRIPTION OF TYPE CHANGES Type - A type is defined as any configuration change that requires an additional Information Element for an Arrangement, Group, or Assembly. If serial number breaks for types are not available, a type # ( Type 1, Type 2, etc.) will be displayed in the caption. These "type" changes are identified with a "C" note (change from previous type) in the Parts List. Only the "types" that apply to this Parts Manual will be included. Additional types may exist causing "C" notes to appear on an Information Element when no other types are shown. 15. <END> This symbol indicates the end of an information element. NOTE: Continuing improvement and advancement of product design may cause changes to your engine which may not be included in this publication. Whenever a question arises regarding your Caterpillar product or this publication, please consult your Caterpillar dealer for the latest available information. SEBP3816-35 GENERAL INFORMATION A5

REPAIR ALTERNATIVES REMANUFACTURED COMPONENTS As an option when making repairs consider Caterpillar Remanufactured Components. Components that are available through the Caterpillar Remanufactured Program are identified three ways in the parts book: • with the letter R in the note field of the parts list • with an R* at the beginning of the first line of the caption • with an *R at the end of the first line of the caption Typical components included in the Remanufacturing Program include: ALTERNATORS CONNECTING RODS CRANKSHAFTS - UNDERSIZE CRANKSHAFTS - UPGRADE TO NEW CYLINDER HEADS ELECTRONIC CONTROL MODULES (ECM) ELECTRONIC SENSORS FUEL INJECTORS FUEL NOZZLES FUEL PUMPS GOVERNORS OIL PUMPS PISTONS SHORT BLOCKS STARTERS TURBOCHARGERS - COMPLETE TURBOCHARGER CARTRIDGES WATER PUMPS Caterpillar Remanufactured engines for many engine arrangements are also available.
