Governor Linkage
(1) Governor
(2) Synchronizing pin
(3) Lever
(4) Governor rig pin
(5) Governor terminal shaft
(6) Rod assembly
(7) Governor control housing
(8) Shaft
(Y) Location for dial indicator
(Z) Location for synchronizing pin
Remove the two plugs from location (Y) and from location (Z) on governor control housing (7).
Remove synchronizing pin (2) from the storage location in the governor control housing. Install the synchronizing pin in the governor control housing at location (Z) 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.
Either an 8T-1000 Electronic Position Indicator or a 4C-6594 Timing and Fuel Setting Tool are acceptable to use. One of these tools will be installed 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.
For the 8T-1000 Electronic Position Indicator, install the 5P-4814 Collet Clamp in the threaded hole at location (Y). Slide the 8T-1002 Probe with the 5P-7263 Indicator Contact Point into the 5P-4814 Collet Clamp until the 8T-1002 Probe sleeve bottoms in the 5P-4814 Collet Clamp. Tighten the collet enough to hold the probe in position. Attach the probe to the 8T-1001 Electronic Indicator. Turn the indicator "ON" and set the indicator to measure millimeters. With the indicator "ON", touch the negative "-" button. Then touch the zero button. 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 fuel control linkage position. 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). Use the appropriate procedure that follows.
If the 8T-1000 Electronic Position Indicator is being used, adjust the rod assembly until the 8T-1001 Electronic Indicator displays a reading of 0.00 mm (0.000 inch). Secure the rod assembly in place with the locknuts. Ensure that each rod end on the rod assembly has the same amount of thread engagement.
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 mm (0.197 inch). Secure the rod assembly in place with the locknuts. Ensure that each rod end on the rod assembly has the same amount of thread engagement.
Rotate governor terminal shaft (5) toward minimum fuel. Put a 5/32 inch hex wrench in governor rig pin (4). Push the rig pin inward and turn the rig pin clockwise until the roll pin unlocks from the bracket. This puts the pin back into the pin's normal running position. The governor is now synchronized to the engine. When the 8T-1001 Electronic Indicator is used, the correct reading is between −9.50 mm (−0.374 inch) and −12.00 mm (−0.4724 inch). If the reading is more positive than −9.50 mm (−0.374 inch), the linkage adjustment procedure must be repeated. −8.75 mm (−0.344 inch)is an example of a number that is more positive than −9.50 mm (−0.374 inch).When the 6V-3075 Dial Indicator is used, the reading should be between −4.50 mm (−0.177 inch) and −7.00 mm (−0.276 inch). If the reading is more positive than −4.50 mm (−0.177 inch), the linkage adjustment procedure must be repeated . −3.75 mm (−0.148 inch)is an example of a reading that is more positive than −4.50 mm (−0.177 inch).
The engine may overspeed due to incorrect assembly or adjustment.Engine overspeed could result in personal injury, loss of life and/or property damage.Be prepared to stop the engine by activating the engine shutdown system or closing the air inlet lines.
The definition of governor deadband is the total amount of travel between the point of actual fuel shutoff and the actual "FUEL OFF" position. When the 8T-1001 Electronic Indicator is used and when the reading of the maximum governor "FUEL OFF" is more positive than −9.50 mm (−0.374 inch), the governor deadband can be eliminated. −8.75 mm (−0.344 inch) is an example of a reading that is more positive than −9.50 mm (−0.374 inch). When the 6V-3075 Dial Indicator is used and when the reading of the maximum governor "FUEL OFF" is more positive than −4.50 mm (−0.177 inch), the governor deadband can be
