INTRODUCTION

Detroit Diesel cautions that the
indiscriminate rebuilding of precision
components, without the benefit of
specifications, specialized equipment,
and knowledge of the electronic
operating system, will jeopardize
performance or lead to more serious
problems, and can take the engine
outside of compliance with U.S. EPA
or CARB emissions standards.

There are other components in
an engine, such as turbocharger,
camshaft, piston, etc., which
are specifically designed and
manufactured to exacting standards
for emissions compliance. It is
important that these components, if
replaced, modified or substituted, can
be verified to ensure that the engine
remains in compliance with emissions
standards. The use of inadequately
engineered, manufactured or tested
components in repair or rebuild of
the engine may be in violation of the
federal Clean Air Act and applicable
U.S. EPA or CARB regulations.

Furthermore, modern engines exhibit
operating parameters which require
the use of proper fluids, such as
fuel, coolant and lubricating oil, to
maintain long engine life. The use of
fluids that do not meet Detroit Diesel
Corporation specifications may result
in early wear out or engine failure.
