Testing and Adjusting
ReferenceRefer to Testing and Adjusting, SENR5594, "Governor - Adjust". Engine Settings
An engine performance validation run MUST be performed on a dyno upon completion of the emissions upgrade. If possible, confirm that the dyno and fuel flow meter have been calibrated before the EUG engine is connected to the dyno. Per EPA requirements, the following parameters must fall within the ceiling/floor ranges specified in the designated test spec in order to receive an engine label:
High Idle Speed
Low Idle Speed
Full Load Speed
Power at Full Load Speed
Fuel Burn Rate at Full Load Speed
Torque Check Speed
Torque at Torque Check Speed
Fuel Burn Rate at Torque Check SpeedIf any of these parameters do not fall within the specifications, the FLS/FTS settings should be adjusted until all specifications are met. A label can only be issued once all of the above mentioned parameters are within the specifications.Note: The values from the dyno tests will be included on the engine labels. For this reason, it is important to have a calibrated dyno and fuel flow meters that can provide accurate measurements for the engine rating being tested.Single HP Instructions
After the installation of the Emission Upgrade Group, set the engine to the reference FLS/FTS settings included in the test specifications. Refer to the following test specification in the Technical Marketing Information (TMI) for the correct engine specifications.
Table 22
Engine Specification    
Engine Serial Number     Specification Number    
S/N:70V     OK-8901    
S/N:11N     OK-8902    
Perform a dyno test. Adjust fuel pump/governor settings in order to get the above listed parameters to fall within the ceiling/floor range on the test spec.
Submit a Validation Form with this information.Note: It is recommended that the engine is not removed from the dyno until the validation form has been received and approved by Caterpillar engineering. This will reduce delays to the customer as adjustments to the engine settings are sometimes required. Caterpillar engineering is not authorized to provide an emissions upgrade label until all of the parameters listed above are within specifications.Installation of the Fuel System Protection Gp

After the engine has been set on the dyno, the Fuel Pump Protection Gp must be installed.
Put fuel ratio control (2) in position on the governor. Make sure that the valve head of the fuel ratio control is connected in the groove of the collar.
Install bolts (3) that hold the fuel ratio control to the governor. Connect air line (1) to the fuel ratio control.
Install Lockwire (5) through the cover bolts and connect the ends of the Lockwire with Wire Seal (4) with Governor Sealing Tool (A) .3406 Engine Emissions Upgrade Group Caterpillar Validation Form
In order to satisfy EPA requirements, a validation form MUST be submitted and approved upon completion of the emissions upgrade. The validation form for the emissions upgrade is found on the Caterpillar Emissions Solutions web site.The following
