Replacement Parts
The emission control systems on your engine were designed, built, and certified
to conform with EPA and California emission regulations. We recommend the use
of genuine parts whenever you have maintenance done. These original-design
replacement parts are manufactured to the same standards as the original parts,
so you can be confident of their performance. The use of replacement parts that
are not of the original design and quality may impair the effectiveness of your
emission control system.
A manufacturer of an aftermarket part assumes the responsibility that the part will
not adversely affect emission performance. The manufacturer or rebuilder of the
part must certify that use of the part will not result in a failure of the engine to
comply with emission regulations.
Maintenance
Follow the maintenance schedule on page 27. Remember that this schedule is
based on the assumption that your machine will be used for its designed purpose.
Sustained high-load or high-temperature operation, or use in unusually wet or
dusty conditions, will require more frequent service.
Air Index
An Air Index Information hang tag/label is applied to engines certified to an
emission durability time period in accordance with the requirements of the
California Air Resources Board.
The bar graph is intended to provide you, our customer, the ability to compare the
emissions performance of available engines. The lower the Air Index, the less
pollution.
The durability description is intended to provide you with information relating to
the engine’s emission durability period. The descriptive term indicates the
useful-life period for the engine’s emission control system. See your Emission
