FILTER-FUEL 1R0762 - Caterpillar

3406B Generator Set EnginesDescription of Change: The EG3P governor actuator is now installed on a shock mounting. This shock mounting reduces vibration wear on the governor actuator. The new shock mounting has extended the governor approximately one-half inch. Therefore, the linkage rod and spline coupler are longer. In addition, new linkage rod ends have a teflon insert between the moving surfaces to reduce friction wear.
Adaptable To: The chart lists the new parts available and the former linkage parts that are replaced. When adapting the new parts to existing governors, the 9Y5292 Isolator is installed directly to the governor drive housing followed by the 9Y5288 Adapter and the 6N2645 Gasket. The isolator and the adapter must be oriented so that the two inner holes are aligned. After the new linkage has been installed, the rack linkage angles should be adjusted as shown in the illustration. Also, linkage calibrations are still made according to the procedure in the service manual for 2301A Electric Governors For Generator Set And Industrial Engines, Form SENR3585, in the Service Procedures section.
