CONTENTS
This manual contains repair instructions for major trac-
tor components, attachments and options. The Table of
Contents at the start of each section lists contents of
that section. Sections are identified by tabs in the right
hand margin.
This manual is to be used in conjunction with the Op-
erator’s Manual and Parts Catalog.
Normal maintenance, adjustment, and operating proce-
dures are also covered in the user Operator’s Manual
and are only included where appropriate in this Service
and Repair Manual.
Engine repair is not covered in this manual. Refer to
the appropriate engine manufacturer’s instructions for
engine service and repair.
This manual includes all removal, disassembly, inspec-
tion, repair, reassembly, installation, adjustment, and
testing procedures. If you, as user of this machine, do
not consider yourself or your repair facilities capable of
a given procedure, please consult your dealer or dis-
tributor.
Information, specifications, illustrations, and procedures
in this manual are based on information in effect at the
time this manual was published. Improvements and
product changes due to continual advancements of the
product design may cause changes to your product
that may not be included in this manual. Each manual
is reviewed and updated as required to include changes
and product improvements.
Read each section completely before proceeding with
specific repairs in that section. You will minimize errors
by understanding what you will be doing and how the
component relates to others in its system. Lists of re-
pair tools and materials for each section of the manual
are given at the start of that section.
The designations L.H. (left hand) and R.H. (right hand)
used throughout this manual refer to the operator’s left
or right when standing in the normal operating position.
INDEX NUMBERS

and installation may have index numbers to call out the

self-evident (eg. linkages, hoses, clamps, etc.) index
numbers are not included.
Repair procedures for items not subject to wear (eg.
panels, brackets, frames) are not included in this man-
ual except for the general procedures given below.
Exercise common sense during disassembly or reas-
sembly; remove only the items required to accomplish
necessary repair or service.
