Introduction

Foreword

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 (CTM86) covers only the base engine. It is one of five volumes on 8.1 L engines. The following four companion manuals cover fuel system repair and diagnostics:

•CTM243—Mechanical Fuel Systems

•CTM134—Level 3 Electronic Fuel Systems

•CTM255—Level 9 Electronic Fuel Systems

•CTM68—Electronic Injection Fuel Systems

Other manuals will be added in the future to provide additional information on electronic fuel systems as needed.

A set of all manuals covering the 8.1 L engines, except CTM68, can be obtained by purchasing CTM450 Binder Set.

Live with safety: Read the safety messages in the introduction of this manual and the cautions presented throughout the text of the manual.

This is the safety-alert symbol. When you see this symbol on the machine or in this manual, be alert to the potential for personal injury.

Use this component technical manual in conjunction with the machine technical manual. An application listing in the introduction identifies engine-models/applications. See the machine technical manual for information on engine removal and installation, and gaining access to engine components.

Information is organized in sections and groups for the various components requiring service instruction. At the end of the book are summary listings of all

applicable essential tools, service equipment, and other materials needed to do the job, service parts kits, specifications, wear tolerance, and torque values.

Before beginning repair on an engine, clean the engine and mount on a repair stand. (See CLEAN ENGINE in Group 010 and see MOUNT ENGINE ON REPAIR STAND in Group 010..)

This manual contains SI Metric units of measure followed immediately by the U.S. Customary units of measure. Most hardware on these engines is metric sized.

Some components of this engine may be serviced without removing the engine from the machine. Refer to the specific machine technical manual for information on components that can be serviced without removing the engine from the machine and for engine removal and installation procedures.

Read each block of material completely before performing service to check for differences in procedures that apply to the engine model number you are working on. If only one procedure is given, that procedure applies to all the engines in the manual.

Component Technical Manuals are concise service guides for specific components. Component technical manuals are written as stand-alone manuals covering multiple machine applications.

Fundamental service information is available from other sources covering basic theory of operation, fundamentals of troubleshooting, general maintenance, and basic types of failures and their causes.

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.

CAUTION: Battery gas can explode. Keep sparks and flames away from batteries. Use a flashlight to check battery electrolyte level.

Never check battery charge by placing a metal object across the posts. Use a voltmeter or hydrometer.

Always remove grounded (-) battery clamp first and replace it last.

CAUTION: Sulfuric acid in battery electrolyte is poisonous. It is strong enough to burn skin, eat holes in clothing, and cause blindness if splashed into eyes.

Avoid the hazard by:

1.Filling batteries in a well-ventilated area.

2.Wearing eye protection and rubber gloves.

3.Avoiding breathing fumes when electrolyte is added.

4.Avoiding spilling or dripping electrolyte.

5.Use proper jump start procedure.

If you spill acid on yourself:

1.Flush your skin with water.

2.Apply baking soda or lime to help neutralize the acid.

3.Flush your eyes with water for 15—30 minutes. Get medical attention immediately.

If acid is swallowed:

1.Do not induce vomiting.

2.Drink large amounts of water or milk, but do not exceed 2 L (2 quarts).

3.Get medical attention immediately.

WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Safety

Prepare for Emergencies

Be prepared if a fire starts.

Keep a first aid kit and fire extinguisher handy.

Keep emergency numbers for doctors, ambulance service, hospital, and fire department near your telephone.

Avoid High-Pressure Fluids

Escaping fluid under pressure can penetrate the skin causing serious injury.

Avoid the hazard by relieving pressure before disconnecting hydraulic or other lines. Tighten all connections before applying pressure.

Search for leaks with a piece of cardboard. Protect hands and body from high pressure fluids.

If an accident occurs, see a doctor immediately. Any fluid injected into the skin must be surgically removed within a few hours or gangrene may result. Doctors unfamiliar with this type of injury should reference a knowledgeable medical source. Such information is available from Deere & Company Medical Department in Moline, Illinois, U.S.A.

Bio-Diesel Fuel

Bio-diesel fuels may be used ONLY if the fuel properties meet DIN 51606 or equivalent specification. It has been shown that bio-diesel fuels have been found to improve lubricity in concentrations up to 5% blend in petroleum diesel fuel.

When using a blend of bio-diesel fuel with fuel pumps, the oil level MUST be checked daily when the air temperature is -10° C (14° F) or lower. If oil becomes diluted with fuel, oil change intervals must be shortened accordingly.

IMPORTANT: Raw pressed vegetable oils are NOT acceptable for use for fuel in any concentration in John Deere engines. These oils do not burn completely, and will cause engine failure by leaving deposits on injectors and in the combustion chamber.

Users of bio-diesel fuel should always remember that a major selling merit is its ability to biodegrade, so the storage and handling of this fuel is very important. This importance can be seen in the following areas of concern:

•The quality of the fresh fuel,

•Water content of the fuel,

•Problems due to aging of the fuel.

Potential problems resulting from deficiencies in the above areas when using bio-diesel fuel in concentrations above 5% may lead to the following symptoms:

•Power loss and deterioration of performance,

•Fuel leakage,

•Corrosion of fuel injection equipment,

•Coked/blocked injector nozzles, leading to poor atomization of fuel,

•Filter plugging,

•Lacquering/seizure of internal components,

•Sludge and sediments,

•Reduced service life.
