Numbering System Significance
This manual uses the following numbering systems:
Specification Number. The product identification
number located on the generator set nameplate.
Specification numbers break down into groups.
Group Number. A unique number representing a parts
group needed to assemble a generator set function. For
example, Group 101 is the Air Intake group.
Variation or Module Number. A group might have
several variations. Each variation performs the same
function with different parts lists. For example, a 50 Hz
generator alternator and a 60 Hz generator alternator
both perform the same function; however, 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 (or exploded-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 generator set nameplate to identify the
generator set spec number.
2. Locate a second generator set nameplate listing
accessories to identify installed modules. On
some models the accessory nameplate is mounted
inside the generator junction box.
3. Turn to the Specification Number Index. The
first column lists the generator set spec numbers.
The headings identify the groups of parts that make
up the generator set.
4. Identify the group most likely to include the
service part number.
5. Find the group variation number at the
intersection of the spec number row and the group
column. Note the variation number.
6. Page forward to locate the group identified in
step 4 or find the appropriate page in the Table of
Contents.
7. Find the part on the illustration and note the item
number of the part or find the part description in
the parts list.
8. Select the part number that corresponds to
your group variation. The first column lists the
illustration item number.
Find the variation
identified in the Specification Number Index or the
module number found on the generator set
nameplate in the appropriate column on the right
side of 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
means the variation/module does 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 or, if contacting the
factory, use the Common Hardware List in the appendix
to identify the common hardware part number and
specifications.
See Common Hardware Application
Guidelines in the appendix for mating hardware
instructions.
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. Use the Common
Hardware List in the appendix to identify the common
hardware hardness.
