5. Installation
Installation of the snowblower chute motor typically involves replacing the existing motor. The following steps are general guidelines. Always refer to your snowblower's specific service manual for detailed instructions.
- Preparation: Ensure the snowblower is turned off, the engine is cool, and the spark plug wire is disconnected to prevent accidental starting.
- Access the Motor: Locate the chute motor assembly on your snowblower. This may require removing covers or other components.
- Disconnect Wiring: Carefully disconnect the electrical wiring from the old motor. Note the orientation of the wires if they are not color-coded or keyed.
- Remove Old Motor: Unbolt or unfasten the old chute motor from its mounting bracket. Keep track of all hardware.
- Install New Motor: Position the new Stens 780-050 motor in the mounting bracket and secure it with the original hardware. Ensure it is firmly seated.
- Connect Wiring: Connect the electrical wiring to the new motor. Ensure connections are secure and correct.
- Test Functionality: Reconnect the spark plug wire. Briefly start the snowblower (if safe to do so) and test the chute rotation mechanism to ensure the new motor operates correctly.
- Reassemble: Reinstall any covers or components that were removed during the process.
If you are not comfortable performing this installation, it is recommended to seek assistance from a certified service technician.

6. Operation
Once installed, the Stens Snowblower Chute Motor 780-050 operates in conjunction with your snowblower's control panel. Typically, a joystick or switch on the control panel allows you to electrically adjust the snow chute's direction. Move the control in the desired direction (left or right) to rotate the chute and direct the expelled snow away from your path.
Ensure the motor responds smoothly to control inputs. If the chute movement is erratic or unresponsive, refer to the troubleshooting section.
7. Maintenance
Regular maintenance helps prolong the life of your chute motor and snowblower. Perform the following checks periodically:
- Visual Inspection: Regularly inspect the motor and its wiring for any signs of wear, corrosion, or damage.
- Electrical Connections: Ensure all electrical connections are clean, tight, and free from moisture.
- Lubrication: Consult your snowblower's manual for any recommended lubrication points for the chute mechanism. The motor itself is typically sealed and does not require user lubrication.
- Cleaning: Keep the motor and surrounding area free from snow, ice, and debris.
8. Troubleshooting
If you encounter issues with your Stens Snowblower Chute Motor, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Chute motor does not operate. | No power, loose wiring, faulty switch, motor failure. | Check power supply to snowblower. Inspect all electrical connections for tightness. Test the control switch. If power and connections are good, the motor may need replacement. |
| Chute moves slowly or erratically. | Low voltage, obstruction in chute mechanism, worn gears. | Ensure snowblower battery (if applicable) is charged. Clear any snow or ice obstructing the chute. Inspect motor gears for wear. |
| Motor makes unusual noises. | Internal damage, worn gears, foreign object. | Discontinue use immediately. Inspect for foreign objects. If noise persists, the motor may be failing and require replacement. |
