If you own a DeWalt DCD940 cordless drill, you’re well aware of its fantastic performance, versatility, and reliability in a variety of applications. However, like any power tool, it can encounter issues over time, particularly with the clutch. The clutch is vital for controlling torque, preventing damage to both the tool and the material being worked on. In this article, we will guide you through the process of changing the clutch in your DeWalt DCD940 drill, ensuring that your trusty tool is back in action quickly and effectively.
Understanding the Clutch in Your DeWalt DCD940 Cordless Drill
Before diving into the step-by-step process of changing the clutch, it’s essential to understand what the clutch does and why it is crucial for your drill’s operation.

Recognizing the signs of a malfunctioning clutch can save you time and frustration. Common symptoms include:
- Inability to adjust torque settings
- The drill spinning freely without applying torque
If you experience any of these symptoms, it’s a clear indication that you need to replace the clutch.
