4. Preliminary Checka. Connector
Check the connection of the connector before a troubleshooting procedure is performed. Inspe
the connector for moisture. Moisture in a connector can cause a poor connection. Ensure that tconnectors are mating correctly. Ensure that the pins in the connector are secure.
b. ContinuityEnsure that continuity is present between the following items:
"C-ground" - "P-ground" "C-ground" - "R-ground" "P-ground" - "Cab-ground"

Turn the disconnect switch to the OFF position before you perform the continuity checks. The
power is OFF in order to prevent damage to the tester and the circuit.
5. Preparationa. Turn the key start switch to the OFF position.b. The hydraulic control lever is in the LOCKED position.c. Ensure that the controller, the harnesses and the connectors are connected.
Note: Ensure that disconnected wires do not contact the machine in order to avoid damage to
electrical components when power is applied.

Replacement For Machines Only With Accelerator Cable
1. Install the actuator.2. Insert the joint of the accelerator cable through the hole in the lever. Install the nut in order to hold the
cable in position.
3. Turn the nut and the locknut of the accelerator cable in the counterclockwise direction until the nuts aseparated.
4. Turn the lever by hand in the counterclockwise direction to the position of high idle.5. Insert the other threaded portion of the accelerator cable into the notch of the support.6. Secure the screw cap and the boot so that the screw cap and the boot will not turn. Then turn the nut
until the governor lever touches the high idle stop.
7. Tighten the nut for two turns more.

8. Tighten the locknut (27 3 Nm (20 2 lb ft)) against the support. Ensure that the nut remains inposition while the locknut is tightened against the support.
9. (If applicable) Reinstall the two clamps to the accelerator cable. Do not allow the cable to twist.Note: Ensure that the governor lever is in contact with the high idle stop. Also, ensure that the nut is
correctly tightened in order to ensure that the accelerator cable has the correct tension. The setting of t
engine speed or an overload condition of the governor actuator could result if the cable is not tightene
correctly.
Note: The minimum allowable bending radius for the cable assembly is 150 mm (6 inch).
Replacement For Machines With Accelerator Cable and Decelerator Cable
1. Repeat step 1 through step 9 in "For Machines Only With Accelerator Cable".2. Insert the joint of the decelerator cable through the hole in the lever. Install the nut in order to hold the
cable in position.
3. Loosen the nut and the locknut on decelerator cable.4. Insert the other threaded portion of the accelerator cable into the notch of the support.5. Tighten the nut until the sag in the bellows is no longer present. Loosen the nut by five turns.
Note: The minimum allowable bending radius for the cable assembly is 150 mm (6 inch).
Adjustment
1. Loosen the nut and the locknut of the accelerator cable. The nuts should be separated as far as possibl2. Install the accelerator cable and the decelerator cable to the lever.3. Insert the threaded section of the accelerator cable into the support.4. Turn the lever clockwise toward the engine until the lever hits the stop for the high idle.5. Tighten the nut until the sag in the bellows is no longer present. The nut should be tightened two
additional turns.
6. Secure the accelerator cable to the support by tightening the locknut.7. Insert the threaded section of the decelerator cable into the notch of the support.8. Tighten the nut until the sag in the bellows is no longer present. Loosen the nut by two turns.9. Secure the decelerator cable to the support with the locknut. Then, tighten the locknut against the nut.
Ensure that the nut does not turn as the locknut is tightened.

Governor Actuator - CalibrateSMCS -1716-524
/sisw eb/sisw eb/ /sisw eb/fulltext/f
Note: The 325C, M325C MH, and 330C series does not have a governor actuator.
This function can memorize the rotation angle of the governor actuator and the no-load engine speed. Thisinformation is saved into the controller after the accelerator cable of the governor actuator has been replaced,installed and/or adjusted. The controller will use the information that was saved in order to determine the targ
position for the actuation of the governor actuator.
Note: Ensure that the calibration procedure for the governor actuator is performed when the governor actuato
the accelerator cable or the controller has been replaced or installed. The temperature of the hydraulic oil shou
be 50 C (122 F) prior to the calibration.
