ACS adjustment
Full load injection quantity at high altitudes and ACS adjusting method
1. Full load injection quantity adjustment
(1)Remove the ACS cover and remove the bellows and adjusting shim.
(2)Perform all adjustments as per the adjustment standard except for ACS adjustment.
2. ACS adjustment
Adjust the ACS so that the reduction amount corresponds to the altitude in the table.

Literature Information
This manual contains information and instructions concerning engine safety, operation, lubrication, and maintenance. Read, study, and keep it available with other literature and engine information.Some photographs or illustrations in this publication show details or attachments that may differ 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 hazardous, warning situations. Read and understand the basic precautions listed in the safety section before operating or performing lubrication, maintenance and/or repair on this product.Operation
Engine operation outlined in this publication is basic. Engine operators gain knowledge of the engine through experience, developing operation skills and techniques which enhance efficient and economical engine operation.The operation section is a reference for operators. Photographs and illustrations guide operators through correct procedures of inspecting, starting, operating and stopping the engine. Discussion of gauges and engine control information is included.Maintenance
The maintenance section is a guide to engine care. The illustrated instructions are grouped by maintenance service intervals. The actual operating environment of the engine also governs the maintenance schedule. Under extremely severe, dusty, or frigid operating conditions, lubrication and maintenance checks more frequent than those specified in the Maintenance Schedule may be necessary.Maintenance Intervals
Use the amount of fuel consumed or use the service hour meter to determine service intervals. Calendar intervals shown (daily, weekly, monthly, etc.) can be used, if they provide more convenient servicing schedules and approximate the indicated service hour meter reading. Recommended service should always be performed at the interval that occurs first.We recommend that the maintenance schedules be reproduced for ease of inspection. We also recommend that ongoing maintenance records be kept to document engine service.See the Maintenance Records section of this publication for information regarding documents that are generally accepted as proof of maintenance or repair. Your Caterpillar dealer can assist you in tailoring your Maintenance Schedule to meet the needs of your operating environment.Overhaul
Major engine repair details are not covered in this manual. Major repairs are best left to trained personnel or an authorized Caterpillar dealer.If a major engine failure requiring removal of the engine occurs, numerous after-failure overhaul options available from your Caterpillar dealer. Contact your dealer for information regarding these options.Engine Description
This publication describes the 3408 and 3412 Marine Diesel Engines. These engines are designed primarily for marine propulsion.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.California
Proposition 65 Warning
Diesel engine exhaust and some of its constituents are known to the state of California to cause cancer, birth defects, and other reproductive harm.
