Magnetos are an essential part of a tractor ignition system. They generate electrical power that ignites the fuel in the engine and keeps the tractor running. Therefore, malfunctioning magnetos can significantly affect the tractor's efficiency. If the various components of a magneto, such as the rotor, coil, and condenser, become worn out over time, the magneto will need to be restored to its original working condition. This article provides a step-by-step guide on how to restore tractor magnetos to their former working state.
Step 1: Safety Precautions
The restoration process begins with ensuring safety. Before opening the magneto, it's crucial to disconnect the magneto's wire from the coil to cut off any electrical supply. Failure to do this could result in an electric shock which can be life-threatening. Additionally, the workspace should be well-lit, and any flammable materials removed from the area. Always wear safety glasses to protect your eyesight throughout the restoration process.
Step 2: Remove the magneto from the tractor
The next step is to remove the magneto from the tractor. Start by removing any parts necessary for convenient removal of the magneto, such as engine covers or tractor battery. Once done, remove the magneto by gently unscrewing the bolts holding it in its place. These bolts are typically located on the side of the magneto. Once the magneto is loose, lift it out carefully and place it on a workbench.
Step 3: Clean the magneto
After removal, the magneto should be cleaned thoroughly to remove any dirt, rust, or corrosion that may have accumulated on the various components. Start by cleaning the magnet's surface with a rag soaked in acetone or any other industrial degreaser. Next, use sandpaper to clean any rust or corrosion on the exterior of the magneto. After cleaning the exterior, proceed to the components inside the magneto. Use a soft-bristled brush to clean the rotor, coil, and condenser but avoid applying too much pressure since they are delicate parts. Remove any debris from the magneto's air vent to ensure adequate airflow.
Step 4: Replace or repair all damaged parts
Inspect all the magneto components, including the coil, rotor, and condenser, to ensure they are functioning correctly. Replace any parts that are damaged, worn out, or corroded. These replacements should be of the same model and make as the original parts. In some cases, the damaged parts may be repairable rather than replacing it entirely, depending on the extent of damage. Always consult a professional mechanic for guidance before attempting any repairs.
Step 5: Reassemble and test the magneto
The last step is to reassemble and test the magneto. Use the original bolts when reassembling the magneto. Connect the magneto's wire to the tractor's coil once all the other components are in place. Finally, start the tractor and check the magneto's efficiency by listening to the engine's sound. If the tractor runs smoothly, then the magnet has been restored to its original working condition. Reinstall all the engine covers or other parts removed during the magneto extraction process.
Conclusion
Restoring magneto's is a task that can be performed by any experienced tractor mechanic or DIY enthusiast. The process outlined above is a guide to help ensure that the magneto is restored to its original working condition. By taking safety precautions during the restoration process, replacing faulty parts, and testing the magneto, tractor owners can be assured that their tractor will remain functional and dependable.
