DESCRIPTION:
John Deere 4.5L & 6.8L Diesel Engines Base Engine Component Technical Manual – PDF DOWNLOAD
- This manual is written for an experienced technician. Essential tools required in performing certain service work are identified in this manual and are recommended for use.
- This manual covers the base engine for PowerTech 4.5L and 6.8L engines including PowerTech “Plus”, PowerTech “E”, and PowerTech “M” engine models. It is one of eight volumes on 4.5L and 6.8L engines. The following seven companion manuals cover fuel system and electronics repair, operation, and diagnostics:
• CTM207 — Mechanical Fuel System
• CTM284 — Level 1 Electronic Fuel System
• CTM170 — Level 4 Electronic Fuel System
• CTM220 — Level 11 Electronic Fuel System
• CTM331 — Level 12 Electronic Fuel System
• CTM320 — Level 14 Electronic Fuel System
• CTM502 — Level 16 Electronic Fuel System - Other manuals will be added in the future to provide additional information on electronic fuel systems as needed.
Live with safety: Read the safety messages in the introduction of this manual and the cautions presented throughout the text of the manual. - Information in this manual is organized in sections and sub divided into groups.
- Section 01 covers the safety measures to follow while repairing the engine; engine identification features, engine emission and application details, and information about the fuels, lubricants, and coolants.
- Section 02a covers the repair and adjustment procedures for 4.5L engines.
- Section 02 covers the repair and adjustment procedures for 6.8L engines.
- Section 03 explains the theory of operation of each system.
- Section 04 is the diagnostics section that provides troubleshooting procedures to find problems.
- Section 05 covers other materials needed to do the job.
- Section 06 summarizes all specifications, wear tolerances, and torque values.
