How do I replace the chuck assembly on my RIDGID R86116 18V Hammer Drill?

[ColeDella]

Replacing the chuck assembly on your RIDGID R86116 18V Hammer Drill can restore its drilling performance. Here's a straightforward guide:

1. Safety First: Always disconnect your RIDGID R86116 18V Hammer Drill from its power source before starting any maintenance or repair work.
2. Remove the Existing Chuck: Use a chuck key to fully open the chuck jaws. Inside, you'll find a small screw. Use a screwdriver to remove this screw.
3. Detach the Chuck Assembly: With the screw removed, you should be able to unscrew the entire chuck assembly from the drill's spindle. Turn it counterclockwise to loosen and remove it.
4. Install the New Chuck: Take your new chuck assembly and screw it onto the spindle, turning it clockwise until it's firmly attached.
5. Secure the Chuck: Reinsert the small screw that you removed earlier back into the chuck and tighten it securely with a screwdriver.
6. Test the Chuck: Open and close the chuck jaws to ensure they operate smoothly.
7. Reconnect and Use: Once you've confirmed the new chuck assembly functions correctly, reconnect the drill to its power source. You're now ready to resume your projects.
