EPA MAINTENANCE

REQUIREMENTS

To maintain optimum engine performance

and compliance with the Environmental

Protection Agency (EPA) Regulations for

Engines, it is essential that you follow the

Periodic Maintenance Schedule on page

46 and the Periodic Maintenance

Procedures on page 49.

EPA Requirements for USA and

Other Applicable Countries

The following are the requirements for the

EPA. Unless these requirements are met,

the exhaust gas emissions will not be within

the limits specified by the EPA.

The EPA emission regulation is applicable

only in the USA and other countries that

have adapted the EPA requirements in part

or in whole. Determine and follow the

emission regulations in the country where

your engine will be operating.

Conditions to Ensure

Compliance with EPA Emission

Standards

The 1GM10, 1GM10C and 1GM10V are

EPA-certified engines.

The following are the conditions that must be

met in order to ensure that the emissions

during operation meet the EPA standards:

• Ambient temperature: -20˚ to +40˚C

(-4˚ to +104˚F)

• Relative humidity: 80% or lower

The diesel fuel should be:

• ASTM D975 No. 1-D or No. 2-D, or

equivalent (minimum of cetane No. 45)

The lubricating oil should be:

• Type API, Class CD or higher

Perform the inspections as outlined in

Periodic Maintenance Procedures on page

49 and keep a record of the results.

Pay particular attention to these important

points:

• Replacing the engine oil

• Replacing the engine oil filter

• Replacing the fuel filter

• Cleaning the intake silencer (air cleaner)

Note: Inspections are divided into two

sections in accordance with who is

responsible for performing the inspection:

the user or the manufacturer.

Inspection and Maintenance

See Inspection and Maintenance of EPA

Emission-Related Parts on page 48 for the

EPA emission-related parts. Inspection and

maintenance procedures not shown in the

Inspection and Maintenance of EPA

Emission-Related Parts on page 48

section are covered in Periodic

Maintenance Schedule on page 46.

This maintenance must be performed to

keep the emission values of your engine in

the standard values during the warranty

period. The warranty period is determined

by the age of the engine or the number of

hours of operation.
