SEAL-O-RING 0689002 - Caterpillar

Engine:
G3412C (S/N: 6ZM1-UP)
The turbochargers on some G3412C Low Emission engines have experienced premature failure of the thrust bearing. The turbocharger thrust bearings were failing due to an abrupt shutdown of the engine while the engine was at rated load and the engine was at rated speed. The thrust bearing for the turbocharger was being starved for oil. In order to correct this failure, an accumulator has been installed to all G3412C Industrial engines. The accumulator supplies the turbocharger bearing housing with oil until the initial thrust of back pressure has ended.The Turbocharger Oil Lines Gp that contains the accumulator can be applied to engines with the following turbochargers: 197-7496 Turbocharger Gp, 122-8043 Turbocharger Gp and 162-9471 Turbocharger Gp The 216-7735 Turbocharger Oil Lines Gp is not available for parts service. Order the individual components for parts service.Note: The use of 225-6998 Tube As or the use of 217-7898 Tube As depends on the type of turbocharger. Determine the part number of the turbocharger that is used on the engine prior to ordering parts.
Before ordering the parts in order to perform this operation, determine what turbocharger is on the engine. Refer to Step #7 in the installation instructions.
