WEICHAI & PSI SERVICE MANUALS AVAILABLE ONLINE AT FLYPARTSGUY.COM INSTALLATION OF CERTIFIED ENGINES Thank you for your recent purchase of an EPA certified WEICHAI Nonroad and Stationary Industrial Engine. These instructions are intended to provide the installer of the engine all the information that is necessary to properly install the engine and related components into the equipment chassis. The United States Environmental Protection Agency (EPA) requires that the manufacturer of the engine provide installation instructions to the equipment manufacturers as defined in the Code of Federal Regulations (40CFR 1048.130).

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. This engine is certified to be used in nonroad and stationary constant speed only equipment applications. Do not install this engine for use in any variable speed applications! This industrial engine comes fully equipped and certified with a complete emissions control system which includes the fuel system, sensors and actuators, a fully integrated engine management system, and an exhaust after treatment system including a three-way catalyst.

When this industrial engine is correctly installed by an Original Equipment Manufacturer (OEM), it will meet or exceed the Emission Standards for Large Spark Ignited (LSI) engines established by the US Environmental Protection Agency (EPA). This engine has been certified to exhaust emission standards in 40 CFR Part 1048 and 40 CFR Part 60 JJJJ including appropriate deterioration factors, over the regulated useful lifetime of seven years or 5000 hours, whichever occurs first. Emissions compliance throughout the useful lifetime requires proper engine maintenance. Please refer to the maintenance schedule in the service manual for details.

WEICHAI & PSI SERVICE MANUALS AVAILABLE ONLINE AT FLYPARTSGUY.COM NOTICE OF IMPORTANT REQUIREMENTS OF CERTIFIED ENGINES Important Notice- The required Emissions Control Information label has been placed on this certified engine during the WEICHAI assembly process. 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 equipment, as described in 40 CFR 1068.105. Contact Weichai to request a duplicate label (Dial 1-855-922-9001). Important Notice- This engine uses a crankcase recirculation system that routes all crankcase gasses back to the engine intake air system.

The EPA requires every certified industrial engine to have a closed crankcase and no crankcase emissions may be vented to the atmosphere as described in the Code of Federal Regulations (40 CFR 1048.115). Please refer to the Intake Air System section included in these instructions for details. Important Notice- To meet EPA exhaust emissions field testing requirements it is important that the OEM design the exhaust system so that a 20-centimeter extension can be temporarily installed on the equipment’s exhaust outlet. The extension is required in order to prevent dilution of the exhaust sample with ambient air during the exhaust emissions test.

Important Notice- EPA requires that WEICHAI warranty all emission-related components as defined in 40 CFR Part 1048.120. Please refer to the Emission Related Warranty Statement included with the sale of all new engines for further details. Warranty for non-critical emissions components will be as defined in the individual purchase agreement.
