John Deere 185, 180, 175, 160, 130 User Manual

FOREWORD

Introduction

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.

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

N

this symbol on the machine or in this manual,
be alert to the potential for personal injury.

Technical manuals are divided in two parts: repair
and diagnostics. Repair sections tell how to repair the
components. Diagnostic sections help you identify the
majority of routine failures quickly.

Information is organized in groups for the various
components requiring service instruction. At the
beginning of each group are summary listings of all
applicable essential tools, service equipment and
tools, other materials needed to do the job, service
parts kits, specifications, wear tolerances, and torque
values.

This manual is part of a total product support
program.

FOS MANUALS—REFERENCE
TECHNICAL MANUALS—MACHINE SERVICE
COMPONENT MANUALS—COMPONENT SERVICE
Fundamentals of Service (FOS) Manuals cover basic

theory of operation, fundamentals of troubleshooting,
general maintenance, and basic type of failures and
their causes. FOS Manuals are for training new
personnel and for reference by experienced
technicians.

Technical Manuals are concise guides for specific
machines. Technical manuals are on-the-job guides
containing only the vital information needed for
diagnosis, analysis, testing, and repair.

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

Binders, binder labels, and tab sets can be ordered
by John Deere dealers direct from the John Deere
Distribution Service Center.

PRACTICE SAFE MAINTENANCE

Understand service procedure before doing work. Keep
area clean and dry.

Never lubricate or service machine while it is moving.
Keep hands, feet, and clothing from power-driven parts.
Disengage all power and operate controls to relieve
pressure. Lower equipment to the ground. Stop the
engine. Remove the key. Allow machine to cool.

Securely support any machine elements that must be
raised for service work.

Keep all parts in good condition and properly installed.
Fix damage immediately. Replace worn or broken parts.
Remove any buildup of grease, oil, or debris.

Disconnect battery ground cable (-) before making
adjustments on electrical systems or welding on
machine.

AVOID HIGH-PRESSURE FLUIDS

Safety

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 may call the Deere &
Company Medical Department in Moline, Illinois, or other
knowledgeable medical source.

CAUTION: Handle fuel carefully. Always stop

engine before refueling. Fill fuel tank outdoors.
If engine is hot, let engine cool several
minutes before you add fuel. Do not smoke
while you fill the fuel tank or service the fuel
system. Fill fuel tank only to bottom of filler
neck.

IMPORTANT: DO NOT mix oil with gasoline.

Unleaded fuel is recommended. Regular leaded gasoline
with an anti-knock index of 87 or higher may be used.
Avoid switch from unleaded to regular gasoline to
prevent engine damage.

Use of gasohol is acceptable as long as the ethyl
alcohol blend does not exceed 10 per cent. Unleaded
gasohol is preferred over leaded gasohol.

Fuel tank capacity is 2-1/2 gal (9.5 L).
Lift seat. Fill fuel tank at end of each day’s operation.

This helps to keep condensation out of fuel tank.

TRACTION DRIVE BELT CARE AND MAINTENANCE

1. The traction drive belt transmits power by friction and
a wedging action against the sheaves. The belt is
subject to normal wear through periodic heavy load and
should be checked regularly. To check for normal wear,
the belt and sides of sheaves should wear evenly.

2. A slight raveling of the belt covering does not indicate
premature failure. Cut off the raveling if the covering
peels at the lap.

M21,5010S,ZA -19-23JAN86

M50314 -UN-26APR89

3. Check for the causes of unusual belt wear as follows:
—Examine sheaves for bent or chipped sidewalls (A).

Check for excessive sidewall wear (B). Damaged
sheaves cause rapid belt wear. A bent sidewall (C)
reduces the gripping power of the belt. Replace sheaves
having any of the above defects.

—Check to be sure dirt has not lodged and packed in
sheave V-groove. Loosen dirt so it will fall out when
tractor is started.

INSPECT TRACTION DRIVE BELT

IMPORTANT: Never pry belt over edge of sheave.

Belt cords may be damaged. Put belt in
sheave groove by hand.

1. Lumpy traction drive belts can cause tractor vibration.
Check belt for swells and lumps. Install only factory
recommended drive belts of the proper length.

2. Whenever unusual traction drive belt failure occurs,
check immediately for the cause. After correcting the
cause, replace drive belt.

M21,5010S,B -19-27MAR86

CLEAN TRACTION DRIVE BELT

10

CAUTION: Do not clean belt while tractor is

N

running.

2

1. Clean belt by wiping with a clean cloth. Immediately
wipe off any spilled oil or grease. Do not use solvents.
They soften the belt and cause the clutch to grab.

2. Do not use belt dressing. Dressings shorten belt life
and often give only temporary gripping action while
softening the belt and causing eventual deterioration.
