Governor linkage (1) Synchronizing pin (2) Governor (3) Lever (4) Ring (5) Governor terminal shaft (6) Rod assembly (7) Governor control housing (8) Shaft (A) Location for synchronizing pin (B) Location for dial indicator
Remove the two plugs from location (B) and from location (A) on governor control housing (7) .
Remove synchronizing pin (1) from the storage location in the governor control housing. Install the synchronizing pin in the governor control housing at location (A) without the spacer. Tighten the synchronizing pin to 10 2 N m (7 1 lb ft).
Rotate shaft (8) in the "FUEL ON" direction until the fuel stop lever is against the synchronizing pin. Hold the shaft (8) in position by installing a 1U-8795 Governor Torque Arm Tool on the opposite end of the governor terminal shaft. The rod assembly connects to the same end.
Install the 4C-6594 Timing and Fuel Setting Tool in the threaded hole at location (Y) of the fuel control housing.
For the 4C-6594 Timing and Fuel Setting Tool, install the 5P-4814 Collet Clamp in the threaded hole at location (Y). Slide the 6V-3075 Dial Indicator with the 5P-7263 Indicator Contact Point into the 5P-4814 Collet Clamp. When the contact point seats against the fuel stop lever, slide the indicator inward or slide the indicator outward until the indicator dial reads +5.00 mm (+0.197 inch). Tighten the collet in order to hold the indicator in position. The indicator is now ready to be used.
Rotate governor terminal shaft (5) toward minimum fuel until governor rig pin (4) can be depressed. Put a 5/32 inch hex wrench in governor rig pin (4). Push the rig pin inward and turn the rig pin counterclockwise until the roll pin locks squarely behind the bracket.Note: Governor rig pin (4) is used while the governor control rod assembly (6) is adjusted in order to stop the governor terminal shaft at a fixed position. This is done in order to synchronize the governor travel with the travel of the engine fuel control linkage. Engage the pin only when the engine is off.
Loosen synchronizing pin (2) for five to six turns.
Gently rotate governor terminal shaft (5) toward maximum fuel until contact is made with the governor rig pin. Hold shaft (3) in place. The dead weight that is used during unit injector synchronization may also be used in order to hold the governor terminal shaft against the governor rig pin.
Adjust rod assembly (6) .
If the 4C-6594 Timing and Fuel Setting Tool is being used, adjust the rod assembly until the 6V-3075 Dial Indicator displays a reading of 5.00
