This page focuses on 4614911 as the main part number. Before ordering, the removed throttle motor should be checked by old part number, connector type, wiring plug, mounting position, voltage and machine serial number.

4614911 Part Number Focus

The main part number for this product page is 4614911. The related number 4360509 may appear in supplier listings and parts references, but final selection should still be verified by the old motor and connector layout.

To keep selection accurate, this page should not be mixed with unrelated throttle motor numbers. Similar throttle motors may differ in connector type, cable length, mounting bracket, internal stepper motor layout or linkage position.

Reference Information for 4614911

Engine Speed Control Function

The 4614911 throttle motor helps control engine speed by moving the throttle linkage according to controller signals. When the throttle motor, wiring or linkage has a fault, the excavator may show unstable idle, poor throttle response or limited engine speed control.

Before replacing the motor, check the external linkage, wiring harness, connector pins, power supply and controller signal. A throttle control fault may be caused by the motor itself, wiring, linkage resistance or calibration condition.

Common Failure Symptoms

• Unstable idle: engine speed may rise and fall if the motor or linkage response is inconsistent.

• No throttle response: check the motor connector, wiring harness, fuse and controller signal.

• Engine speed cannot increase: the motor, linkage or control signal may need inspection.

• Abnormal motor noise: worn internal gears or mechanical resistance may cause noise during movement.

• Fault code or warning: check the machine diagnostic information together with wiring and motor movement.

Troubleshooting Before Replacement

• Confirm whether the old motor number matches 4614911.

• Compare the connector type, wiring plug, mounting holes and cable direction.

• Inspect the throttle linkage and ball joints for sticking or excessive resistance.

• Check the wiring harness, fuse, ground point and connector pins before replacing the motor.

• Confirm whether recalibration or adjustment is required after installation according to the machine service procedure.

Installation and Maintenance Notes

• Disconnect battery power before replacement.

• Record the old motor position and linkage connection before removal.

• Do not force the linkage if it does not move freely.

• Keep the connector clean and dry during installation.

• After installation, check idle speed, throttle response and full travel movement.

• If the machine requires calibration, complete the adjustment before returning the excavator to work.
