About this document

This repair and service manual is dedicated for the mechanics and the workshop personnel of

This repair manual provides information regarding the assembly, disassembly, and adjustment

tasks for KOHLER Diesel engines.

Information

Information for the United States

Failing to follow these instructions when installing a certified engine in a piece of nonroad

equipment violates federal law (40 CFR 1068.105(b)), subject to fines or other penalties as

described in the Clean Air Act.

If you install the engine in a way that makes the engine's emission control information label

hard to read during normal engine maintenance, you must place a duplicate label on the equip‐

ment, as described in 40 CFR 1068.105.

Some sections of this manual do not apply to all engines.

Some illustrations in this repair and service manual show details and implements that may be

different from your engine and machinery.

Protective devices and covers have been removed to provide a clearer representation in some

illustrations.

KOHLER engines are subject to continuous development and improvement. This may result in

modifications to your engine which may not be referred to in this repair and service manual.

If you require further explanations or information, please contact your nearest authorized

Kohler service representative. See “Service Assistance” section.
