Introduction

In this article, we will discuss the step-by-step process of removing a rotor and stator from a Briggs & Stratton generator. We will cover the necessary precautions, tools required, and provide detailed instructions on each stage of the process. If You've had questions or faced challenges in removing the rotor and stator in the past, this article aims to provide a comprehensive guide to help you successfully complete the task. So let's dive in and learn how to remove a rotor and stator from a Briggs & Stratton generator effectively.

1. Disconnecting the Wires

Before starting the removal process, it is crucial to disconnect the wires from the generator. This ensures safety and prevents any damage to the electrical components. Make sure to follow the manufacturer's instructions or consult a professional if you are unsure about which wires to disconnect.

2. Removing the Legs from the Frame

To make the stator and rotor removal easier, it is essential to free the legs from the generator frame. Locate the bolts securing the legs to the frame, typically two on each side, and remove them carefully. This will allow the stator to become loose and facilitate smoother removal.

3. Removing the Rotor Bolt

Removing the rotor bolt can be a challenging task, as the rotor tends to spin when attempting to loosen the bolt. To overcome this, start by removing the spark plug and positioning the piston at bottom dead center. Then, fill the cylinder with a rope to prevent the piston from moving. This will provide the stability needed to successfully remove the rotor bolt.

4. Securing the Piston at Bottom Dead Center

To secure the piston at bottom dead center, use a screwdriver or a suitable tool to find the correct position. This position allows you to open up the cylinder, creating space to insert the rope. Ensure the rope is inserted adequately to prevent the engine from turning over when removing the rotor.

5. Removing the Stator

In most cases, removing the stator involves removing the bolts that secure it. However, for certain generator models with two-piece Bell housings, removing only the shorter bolts on the top and bottom will allow the stator to slide out easily. Prioritize disconnecting any wires attached to the stator and remove the brushes to prevent any damage during the removal process.

6. Supporting the Engine

When removing the stator and housing, it is crucial to support the engine to prevent the rotor from crashing to the floor. Ensure the engine is adequately supported by using appropriate tools or methods. This precautionary step prevents potential damage to the rotor and other components.

7. Separating the Stator and Housing

Once the engine is properly supported, use a puller to Apply light pressure and separate the stator from the housing. Exercise caution while using the puller, as excessive force can cause damage. Applying light pressure and twisting the puller by HAND is generally effective. However, if using a wrench, opt for a small one and apply gentle pressure.

8. Tapping Threads for the Rotor

In certain cases, the rotor may require threaded holes for removal. Measure the diameter of the hole and determine the appropriate tap size. Carefully tap the hole with the correct size tap. Use cutting oil or a suitable lubricant to facilitate smooth threading. This step ensures that the rotor can be easily removed in the subsequent steps.

9. Cutting a Rod for Removing the Rotor

To remove the rotor, a rod is required. Cut a rod that will fit down the shaft without reaching the end. The rod should be about a quarter to a third of an inch shorter than the total length. Choose a rod with a diameter that matches the size of the hole, ensuring it is wide enough to prevent damage to the threads on the crankshaft.

10. Screwing in the Bolt and Removing the Rotor

Insert the rod into the shaft and screw in the bolt about a third of an inch. Use the remaining threads to push the rod and remove the rotor. Apply slight pressure with a breaker bar, turning it in a controlled manner. Typically, one or two turns are sufficient for the rotor to come off. Take caution as the rotor may launch out forcefully.

11. Conclusion

Congratulations! You have successfully removed the rotor and stator from your Briggs & Stratton generator. Follow the reverse steps to reinstall the components, ensuring proper alignment and connections. Remember to prioritize safety throughout the process and consult a professional if you encounter any difficulties or uncertainties.

By following this step-by-step guide, you can confidently remove the rotor and stator from your Briggs & Stratton generator, allowing for necessary repairs or maintenance. Enjoy the satisfaction of completing the task and the convenience of having a functional generator.

FAQ

Q: Can I remove the rotor and stator without disconnecting the wires? A: It is highly recommended to disconnect the wires before attempting to remove the rotor and stator. This ensures safety and prevents any damage to the electrical components.

Q: Do I need any special tools to remove the rotor and stator? A: While basic tools are generally sufficient, you may need a puller to separate the stator and housing. Additionally, having a tap and a cutting tool for a rod may be necessary depending on the specific requirements of your generator.

Q: What precautions should I take during the removal process? A: It is crucial to support the engine properly to prevent the rotor from crashing to the floor. Additionally, exercise caution while applying pressure with the puller or breaker bar to avoid any damage to the components.

Q: Can I reuse the rotor and stator once removed? A: If the rotor and stator are undamaged, they can typically be reused after cleaning and inspection. However, it is recommended to consult a professional to assess their condition and determine if any repairs or replacements are necessary.
