TP-6388 12/08

This manual lists service replacement parts for 

generator set models listed on the front cover. 

Information in this publication represents data available 

at the time of print. Kohler Co. 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. 

Specification Number Index. Lists the generator set 

specs and groups. 

Group Parts Lists. List the part numbers of parts in the 

groups. 

Kit Sections. List modules and accessories and their 

parts. 

Appendices. Include Abbreviations, Common 

Hardware Application Guidelines, General Torque 

Specifications, Common Hardware Identification, and 

Common Hardware List. 

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. 

TP-6388 12/08 

Introduction 

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.

Appendix B Common Hardware Application Guidelines 

Use the information below and on the following pages to 

identify proper fastening techniques when no specific 

reference for reassembly is made. 

Bolt/Screw Length: When bolt/screw length is not given, 

use Figure 1 as a guide. As a general rule, a minimum 

length of one thread beyond the nut and a maximum 

length of 1/2 the bolt/screw diameter beyond the nut is 

the preferred method. 

Washers and Nuts: Use split lock washers as a bolt 

locking device where specified. Use SAE flat washers 

with whiz nuts, spiralock nuts, or standard nuts and 

preloading (torque) of the bolt in all other applications. 

See Appendix C, General Torque Specifications, and 

other torque specifications in the service literature. 

Preferred Nut/Bolt Clearance 

1 2 

Unacceptable Nut/Bolt Clearance 

1. 1/2 of bolt diameter 

2. Min. 1 full thread beyond top of nut 

3. Below top of nut 

Figure 1 Acceptable Bolt Lengths

G-585 

Steps for common hardware application: 

1. Determine entry hole type: round or slotted. 

2. Determine exit hole type: fixed female thread 

(weld nut), round, or slotted. 

For round and slotted exit holes, determine if 

hardware is greater than 1/2 inch in diameter, or 

1/2 inch in diameter or less. Hardware that is 

greater than 1/2 inch in diameter takes a standard 

nut and SAE washer. Hardware 1/2 inch or less in 

diameter can take a properly torqued whiz nut or 

spiralock nut. See Figure 2. 

3. Follow these SAE washer rules after determining 

exit hole type: 

a. Always use a washer between hardware and a 

slot. 

b. Always use a washer under a nut (see 2 above 

for exception). 

c. Use a washer under a bolt when the female 

thread is fixed (weld nut). 

4. Refer to Figure 2, which depicts the preceding 

hardware configuration possibilities.

Notes: 

1. The torque values above are general guidelines. Always use the torque values specified in the service manuals and/or assembly 

drawings when they differ from the above torque values. 

2. The torque values above are based on new plated threads. Increase torque values by 15% if non-plated threads are used. 

3. Hardware threaded into aluminum must have either two diameters of thread engagement or a 30% or more reduction in the torque to 

prevent stripped threads. 

4. Torque values are calculated as equivalent stress loading on American hardware with an approximate preload of 90% of the yield strength 

and a friction coefficient of 0.125.
