AIR CLEANER GP 3531379 - Caterpillar

Personal injury or death can result from flying objects generated by engine overspeed. The engine could overspeed as a result of improper linkage assembly, adjustment, or governor deadband. Be prepared to stop the engine by activating the engine air shut-off or closing the air off to the air inlets.
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 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 eliminated. −3.75 mm (−0.148 inch) is an example of a reading that is more positive than −4.50 mm (−0.177 inch). This can cause engine overspeed.
Tighten synchronizing pin (2) to a torque of 10 2 N m (7 1 lb ft).
Gently rotate the governor terminal shaft toward the maximum fuel position until the fuel stop lever makes contact with synchronizing pin (2) .
When the 6V-3075 Dial Indicator is used, ensure that the dial indicator still reads +5.00 mm (+0.197 inch). If indicated reading is not correct, repeat Steps 3 through 9. If the indicated reading is correct, continue with the procedure. If the 6V-3075 Dial Indicator is used, adjust the dial indicator in order to read 0.00 mm (0.000 inch). This must be done before continuing the procedure.
Check the fuel setting. Refer to System Operation, Testing and Adjusting, "Fuel Setting Check".
Remove the 1U-8795 Governor Torque Arm Tool from the governor terminal shaft.
Remove synchronizing pin (2) from hole (A), and install the plug. Install the synchronizing pin and the spacer in the storage location.
Remove all tooling from location (B) in the governor control housing. Install the plug at location (B) .
Before starting the engine, put a mark on the governor position indicator at the point of minimum governor travel. This is the engine's stopped position.
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.
Note: It may be necessary to back off the fuel ratio control setting in order to start the engine after this adjustment. This is done by first removing the plug from the right front corner of the governor's top cover. The governor is viewed from the end of the governor output shaft. Put a 3/16 hex wrench through the hole in the top cover until the wrench engages the adjustment screw. Turn the screw in the counterclockwise direction until the engine is able to start. This will take several turns.
Start the engine and operate the engine at low idle. Put a mark on the governor position indicator. This is the engine running position.
The engine running position of the governor must be six or more degrees above the engine's stopped position.
Operate the engine at high idle with no load in order to ensure that the
