Literature Information
This manual contains safety, operation instructions, lubrication and maintenance information. Read - study - and keep it with the truck literature and engine information.Some photographs or illustrations in this publication show details or attachments that may be different from your engine. Guards and covers may have been removed for illustrative purposes.Continuing improvement and advancement of product design may have caused changes to your engine which are not included in this publication.Whenever a question arises regarding your engine, or this publication, please consult your Caterpillar dealer for the latest available information.Safety
The safety section lists basic safety precautions. In addition, this section identifies the text and locations of warning labels used on the engine.Read and understand the basic precautions listed in the safety section before operating or performing lubrication, maintenance and repair on this product.Operation
Operating techniques outlined in this publication are basic. This manual will assist you with developing the skills and techniques required to operate your engine more efficiently and economically.The operation section is a reference for operators. Photographs and illustrations guide the operator through correct procedures of inspecting, starting, operating and stopping the engine. This section also includes a discussion of gauges, protection devices, lifting and storage information.Maintenance
The maintenance section is a guide to engine care. The illustrated, step-by-step instructions are grouped by Preventive Maintenance servicing intervals. Items in the Maintenance Schedule are referenced to detailed instructions that follow.Recommended service should always be performed at the interval that occurs first (i.e. fuel consumption figure, distance [odometer] traveled or service hours).Under very severe, dusty or freezing cold operating conditions, more frequent maintenance than is specified in the Maintenance Schedule may be necessary. Refer to the Severe Service Application topics in this publication for the information.Maintenance Intervals
Perform maintenance on items at multiples of the original requirement. The maintenance interval for each item listed in the Maintenance Schedule is primarily based on the item and its relationship to either engine speed or load.We recommend that a maintenance record be maintained as part of the engine's permanent record. See the Maintenance Records section of this publication for information regarding documents that are generally accepted as proof of maintenance or repair.Your authorized Caterpillar dealer can assist you in tailoring your Maintenance Schedule to meet the needs of your operating environment.Overhaul
Major engine repair such as overhaul is not covered in this manual. Major repairs are best left to the trained personnel of an authorized Caterpillar dealer.Your Caterpillar dealer offers a variety of options regarding overhaul programs. Contact your dealer for information regarding these options.If you experience a major engine failure which necessitates removal of the engine from the chassis, there are numerous overhaul options available from your Caterpillar dealer.Engine Description
The engines described in this publication are the 3406 ATAAC Diesel Truck engines equipped with Electronic or Mechanical fuel systems.They are designed primarily for on-highway heavy duty applications.Engine Storage
For general information, refer to the Engine Lifting & Storage topic. For complete engine storage information refer to Special Instruction SEHS9031, Storage Procedure for Caterpillar Products.
