Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Note: Inspect all parts of the governor upon assembly. For information on the reusability of components in the governor, refer to the Guideline For Reusable Parts And Salvage Operations, SEBF8434, "3100 Governor Inspection and General Information for Mechanical Governor Groups Used in 3114, 3116, and 3126 Engines Equipped with Mechanical Unit Injectors (MUI)". For information on cleaning the components in the governor, refer to the The Cleaning Guide, SEBF8354, "Equipment And Chemical Recommendations Reference Manual".Note: Refer to Chart A "Parts to be Replaced During Rebuild" in Guideline For Reusable Parts And Salvage Operations, SEBF8434 for a list of components that need to be replaced during a governor rebuild. It is not necessary to replace the components in Chart A "Parts to be Replaced During Rebuild" if the governor is in the shop for a bench test or for minor repair.Note: Refer to Chart B "Parts Replacement Chart" in Guideline For Reusable Parts And Salvage Operations, SEBF8434 for a list of components that need to be replaced when the servo assembly is serviced.Note: Put clean engine oil on all parts before assembly. Ensure that all of the oil passages in the governor are clean and free of obstructions.
