How to Replace the Chuck on a Makita Impact Driver

1. Remove the retaining ring

Use a pick and a small screwdriver to pry the retaining ring away from the driver. Focus on one side and once it is free of the anvil, pry up the rest of the ring.

2. Remove the chuck assembly

With the retaining ring out of the way, you can remove the flat washer, spring, and chuck collar from the driver. There are two ball bearings in the anvil, you can tap the driver on your work surface to release them.

If you have a bit broken off in the anvil, you can tap it out or use your pick to push it out of the anvil.

3. Install the chuck assembly

Set the bearings, chuck collar, spring, and flat washer back into place.

4. Install the retaining ring

Get one end of the retaining ring secured on the anvil. Then use a small screwdriver to help you slide the retaining ring around the anvil so it secures the chuck assembly.
