All Industrial, Marine And Generator Set EnginesReference: "Comparison Of Fuel Timing Tolerances For Field Settings" in this same issue.The purpose of this article on the engine information plate is to inform dealers of the importance of the data on the plate, how to replace the plate, and to explain some of the specifications and their tolerances.
An understanding of performance specifications and their tolerances, and the correct adjustment of all fuel system and governor settings are important to ensure the factory designed performance and fuel economy.
More Data Added To Engine Information Plate
The engine information plate installed on all engines in all applications has been expanded to include the full torque static fuel setting (A), and air/fuel ratio dynamic (running) setting (B). See Illustration 1. Previously this data was only available in the fuel setting and related information (0T) Microfiche. The other information on the plate remains the same, but has been rearranged. This plate is not serviced by the "9L" number on the plate.
Illustration 1. New information plate.The engine information plate is located on the valve cover, except on the 3500 Series Engines where it is on the middle inspection plate below the cylinder head.
Changing The Engine Information
A new 4W5140 Parts Service Engine Information Plate is available for use when engine arrangements or ratings are changed in the field. See Illustration 2. Items (A) and (B) have also been added to this parts service plate. The plate has blank spaces for all the engines specifications. It must be installed on top of the old plate so the original serial number shows. Do not remove the existing plate.
Illustration 2. The special parts service plate to use if the ratings are changed in the field.To install the parts service plate: 1. Thoroughly clean the old plate.2. Stamp the new information and the unchanged information on the parts service plate. Straighten the plate if necessary.3. Pull off the protective back and break off the lower section of the plate at the scribed mark.4. Use Loctite Company "Depend(R)" two part adhesive to provide a permanent bond between the old plate and the parts service plate. Follow the instructions for the adhesive carefully. If the adhesive is premixed, it will not bond properly.5. Position the plate so the "arrangement number" block is directly over the "arrangement number" block on the old plate.
Loctite "Depend®" is now being used to install the original engine information plates at the factories. It is planned to make this available from Caterpillar.Replacing An Entire Information Plate
If the entire information plate is missing, the model, serial number and performance specification number on the engine serial number plate can be used to temporarily locate performance specifications until a replacement information plate can be obtained. A replacement information plate is available from the factory at no charge. However, a replacement information plate cannot be ordered by part number. To protect the user, dealers must verify ownership of the engine or equipment. The model, serial number, arrangement number and performance specification number can then
