1.1
Introduction
This manual is intended for use by the operator of a Detroit™ engine used in On-Highway Vehicle applications.
1.2
Non-Genuine and Rebuilt Component Quality Alert
Maintenance procedures must be followed in order to continue satisfactory engine performance and durability and to ensure
engine coverage under the manufacturer's warranty. Many of these maintenance procedures ensure that the engine complies
with applicable emissions standards. Proper maintenance procedures, using specific components engineered to comply with
emissions regulations, may be performed by an authorized Detroit™ distributor or dealer, an independent outlet or the
operator / owner. The owner is responsible for determining the suitability of components to maintain emissions compliance
during the engine's useful emission life.
Detroit™ 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 emissions standards.
There are several other components in an engine, such as turbocharger, that 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 emissions standards 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™ specifications may result in
premature wear or engine failure.
1.3
Personnel Requirements
Work on the engine should be carried out only by skilled technicians who have been instructed in the specific skills necessary
for the type of work being performed.
1.4
Engine Conversions and Modifications
The function and safety of the engine could be affected if unauthorized modifications are made to it. Detroit™ will not accept
responsibility for any resulting damage.
Tampering with the fuel injection system and engine electronics could also affect engine power output or exhaust emission
levels. Compliance with the manufacturer's settings and with statutory environmental protection regulations cannot then be
guaranteed.
