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: Early Type I Governors had limited production until 1991. The early Type I Governors may be inspected and perhaps reconditioned. However, some of the internal components are no longer serviced or the internal components may only be serviced by larger assemblies. When you recondition a Type I Governor, it may be necessary to replace the governor. If extensive repair work is necessary, a Type I Governor can be replaced with a Type IV Governor.Note: Put clean engine oil on all parts before assembly. Ensure that all of the oil passages in the governor are free of obstructions.
