Introduction
Use this guide to replace a defective fan and bearing Cap in your Ryobi P411. The Fan is the part that is inside the sander that spins when the machine is activated, and the bearing cap is the part that holds the pad assembly. If your device is not working the problem might be a faulty fan and bearing cap. Before replacing the fan and bearing cap, make sure to review the troubleshooting page to make sure nothing else is preventing your Ryobi P411 from turning on. Make sure to remove the battery before beginning.
