Introduction
This manual lists service replacement partsfor John Deere
4039 and 4045 engines.
At thetime ofprint this manual applied tothe enginemodels
listed in the Specification Number Index. On occasion this
manual may apply to engines not listed in the Specification
Number Index.
Information in this publication represents data available at
the time of print. The generator set manufacturer reserves
the right to change this publication and the products
represented without notice and without any obligation or
liability whatsoever.
This manual includes the following main sections:
Table of Contents. Lists the sections of the manual.
Introduction (and other information sections).
Contains introductory material about part numbers,
illustrations, and hardware.
Index. Lists the engine models and groups.
Group Parts Lists. List the part numbers of parts in the
groups.
Numbering System Significance
This manual uses the following numbering systems:
Engine Model. The product identification number located
on the engine nameplate.Engines break down into
groups.
Group Number. A unique number representing a parts
group needed to assemble an engine function.For
example, Group 1 is the Air Intake group.
Variation Number. A group might have several variations.
Each variation performs the same function with different
parts lists. For example, a 12-volt alternator and 24-volt
alternator both perform the same function, but, with
different parts. Each difference requires a group variation
or module number.
Part Number. The part number identifies an individual
assembly, subassembly, component, or accessory kit.
Illustrations
Illustrations (orexploded-view drawings) best representing
the widest range of variations accompany most groups in
this manual. Illustrations do not depict all details and may
not show all parts. Do not use illustrations for assembly or
disassembly.

How to Find Part Numbers
Use the following steps to locate a service replacement
part.
1. Locate the engine nameplate to identify the enginemodel number.
2. Turn to the Specification Number Index. The first
column lists the engine model numbers.The
headings identify the groups of parts that make up the
engine.
3. Identify the group most likely to include the service
part number.
4. Find the group variation number at the intersection
of the model row and the group column. Note the
variation number. If 2 or more variation numbers are
listed, note all variation numbers.
5. Page forward to locate the group identified instep 3
or find the appropriate page in the Table of Contents.
6. Find the part on the illustration and note t he item
number of the part or find the partdescription in theparts list.
7. Select the part number that corresponds to yourgroup variation. The first column lists the illustration
item number. Find the variation(s) identified in the
Specification Number Index in the appropriate
column onthe right sideof the parts list table. Find the
quantity used at the intersection of the item number
row and the variation column. A blank space at the
intersection meansthe variation/moduledoes not use
that part number.
Hardware References
Many common hardware items do not appear in parts
manuals or will appear as common hardware entries. A
common hardware entry lists the size of the hardware. For
example, an item that appears as “Hardware, 3/8-16” in the
text means that the piece is 3/8-16 size. Obtain common
hardware locally.
Some hardware items require a specific size or some other
characteristic. In that case, use the part number listed in
the text.
When replacing hardware, do not substitute inferior
grade hardware. Replacement hardware grade should be
equal to or better than the grade of the manufacturer’s
original hardware.
