PLATE-PULLER 9U6234 - Caterpillar

Illustration 1. Sample Engine Information Plate.Case I
If there is no information known about the engine serial number, 0T Specification, or vehicular product identification number, the turbocharger should have a tag with the part number on it, and the unit injectors or fuel nozzles should have part numbers stamped on them.
Case II
If neither the engine serial number nor the 0T Specification is known, but the vehicular product identification number is known, use the Product Information System, screen 06 (INQ PM S/N List), to find the serial number of the engine in that vehicle. Once the engine serial number is known, go to ETDS, screen 18 (Engine History Info), to find the 0T Specification.
Illustration 2. Path used (Case I, Case II, etc.) depends upon information known.Case III
If the engine serial number is known but neither the 0T Specification nor vehicular product identification number is known, go directly to ETDS screen 18 to find the 0T Specification. If no history is available for the engine on ETDS screen 18, the engine may have been produced prior to mid-1982, and therefore has no 0T Specification. In that case, consult Fuel Setting Information microfiche SEFU5735, SEFU5736, SBFY1106, or SBFY1107. These microfiche cover engines produced prior to the advent of 0T Specifications.
If all of these avenues of research are exhausted, and no answers can be found, contact an Engine Division Product Analyst for help.
