Removing The Old Drive Unit
Removing the old drive unit from your Milwaukee angle drill is the first step to keep your tool working well. This process needs care and the right steps to avoid damage. Follow the instructions to take off the worn-out parts safely.
Start by making sure the drill is safe to handle. Then, remove parts one by one. This will help you reach the drive unit easily. Use simple tools and take your time for the best results.
Detach The Battery
Always remove the battery before starting any work on your drill. This stops the drill from turning on by mistake. Press the release button and pull the battery out carefully. Keep the battery away from your work area.
Remove The Chuck

Secure With Screws
Use the original screws or the new ones that came with the unit. Tighten them evenly to keep the drive unit steady. Avoid over-tightening to prevent damage. A firm, secure fit is the goal here.
Reattach The Chuck
Place the chuck back on the drive unit’s spindle. Twist it until it locks into place. Check that the chuck spins freely without wobbling. This step completes the installation and gets your drill ready.
