Cummins®

Introduction

The Cummins 4941179 Speed Indicator Ring is a component designed to provide accurate speed data for commercial trucks equipped with Cummins engines. This part plays a role in the vehicle’s operation by ensuring that the speedometer and other speed-related systems receive precise information. Accurate speed data is important for safe driving, efficient fuel consumption, and proper maintenance scheduling ¹.

Function and Operation

The Speed Indicator Ring operates by interacting with the vehicle’s speed sensor. As the ring rotates with the transmission output shaft, it passes by the sensor, generating electrical signals that correspond to the vehicle’s speed. These signals are then processed by the truck’s electronic control unit (ECU), which uses the data to display the vehicle’s speed on the dashboard and to make adjustments to other systems as necessary. The ring’s design ensures that it provides consistent and reliable speed readings under various driving conditions ².

Key Features

This Cummins part is characterized by its robust design and high-quality materials. It is typically made from durable metals that can withstand the harsh environments encountered in commercial trucking. The ring features precise machining to ensure accurate signal generation. Additionally, its design allows for easy installation and replacement, minimizing downtime for maintenance procedures ³.

Benefits

The use of the Speed Indicator Ring offers several advantages. It provides improved accuracy in speed readings, which is important for safe driving and compliance with speed regulations. Enhanced safety is a direct result of accurate speed data, as it allows drivers to maintain appropriate speeds in various conditions. Furthermore, accurate speed information can contribute to better fuel efficiency by enabling the ECU to make more informed decisions regarding engine performance. Regular, accurate speed data also aids in maintenance scheduling, allowing for predictive maintenance based on actual usage patterns.

Installation and Compatibility

Proper installation of the 4941179 is critical to ensure its effective operation. Installation should follow manufacturer guidelines to avoid issues such as misalignment or improper seating, which could lead to inaccurate readings. The ring is compatible with a range of Cummins engine models, and it is designed to integrate seamlessly with the truck’s existing speed sensor and ECU systems. It is important to verify compatibility with specific engine models and truck configurations to ensure optimal performance.

Maintenance and Troubleshooting

Regular maintenance of the Speed Indicator Ring involves inspecting it for signs of wear or damage and ensuring that it remains properly aligned and seated. Cleaning the ring and its surrounding components can prevent buildup that might interfere with its operation. Common issues with the speed indicator ring may include inaccurate speed readings or complete failure to register speed. Troubleshooting steps may involve checking the ring for physical damage, ensuring proper installation, and verifying the functionality of the speed sensor and related electrical connections.

Safety Considerations

When handling, installing, or maintaining the 4941179, it is important to follow safety guidelines to protect personnel and ensure the proper functioning of the truck. This includes wearing appropriate personal protective equipment (PPE), ensuring that the vehicle is properly supported and secured during maintenance, and following all manufacturer instructions for installation and troubleshooting. Additionally, it is crucial to ensure that the ring is installed correctly to avoid any safety risks associated with inaccurate speed readings.
