how to set points gap on tractor

Tractors are heavy-duty vehicles used in a variety of farm processes. One important maintenance aspect of a tractor is setting the points gap, which determines the timing and duration of the electrical charge that ignites the engine. This article provides a comprehensive guide on how to set points gap on a tractor.

Step 1: Safety Precautions

Before setting the points gap on your tractor, it is important to ensure that all safety measures are in place. Ensure that the tractor is parked on a level surface and that the engine is switched off. Put on your safety gear, including gloves and eyewear, to protect yourself from any potential accidents.

Step 2: Accessing the Distributor Cap

The next step is to access the distributor cap. Open the hood of your tractor and locate the distributor cap, which is usually a cylindrical component with several spark plug wires running from it. Remove the distributor cap by undoing the screws that hold it in place.

Step 3: Locating the Points

Once you remove the distributor cap, you will see the points: two small metal contactors located within the distributor. In most tractors, the points are located at the base of the distributor. Use a flashlight to locate them if necessary.

Step 4: Setting the Points Gap

Using a feeler gauge, you can now set the points gap to the manufacturer's specifications. The points gap is the distance between the two points when they are open. To set the gap, insert the feeler gauge between the two points and adjust the points until they are just touching the gauge. Tighten the points lock screw to hold them in place.

Step 5: Testing the Points Gap

After setting the points gap, you need to test it to ensure that it is accurate. Use a multimeter to check the resistance between the two points. Ideally, the points gap should show a resistance of between 0.4 and 0.6 ohms. If the resistance is not within this range, repeat the setting process until it is accurate.

Conclusion

Setting the points gap on your tractor is crucial to maintaining its optimal performance. By following the simple steps outlined in this guide, you can accurately set the points gap and ensure that your tractor works smoothly. Remember to always take safety precautions when working on your tractor to prevent accidents.
