The document provides instructions for removing and installing a governor from a 3116 diesel engine. It describes:
1) Removing the governor by disconnecting linkages, tubes, and clips then removing mounting bolts. O-rings must also be removed from the governor and cylinder head.
2) Installing the governor requires replacing the O-rings, reconnecting linkages and tubes using special tools, and adjusting fuel settings after installation.
3) Additional documents are referenced for more information on governor inspection, testing, and components. Precautions are provided to keep parts clean and contain fluids during the process.
