How to Adjust Distributor Points: A 5-Step Guide for Beginners
Meta Title: How to Adjust Distributor Points: A Complete Beginner’s Guide
Meta Description: Learn how to accurately adjust distributor points on your vehicle’s ignition system. This comprehensive guide provides a step-by-step process, troubleshooting tips, and safety precautions for beginners.
The heart of your classic car’s ignition system – the distributor – is a marvel of mechanical engineering. But this crucial component needs precise adjustment for optimal engine performance. Incorrect distributor point settings can lead to poor starting, rough idling, misfires, and ultimately, damage to your engine. This detailed guide will empower you to confidently handle distributor points adjustment, even if you’re a complete novice.
1. Understanding the Role of Distributor Points
The distributor points are a crucial part of your vehicle’s ignition system. They’re essentially a set of contacts that open and close, creating the electrical signal that fires the spark plugs. Accurate distributor points adjustment ensures the spark occurs at precisely the right moment in the engine’s cycle.
1.1 The Point Gap’s Importance
The gap between the distributor points is critical. Too wide a gap leads to weak sparks and misfires, while too narrow a gap can cause arcing, overheating, and burned points. The correct gap is usually specified in your vehicle’s service manual, often between 0.016″ and 0.020″ (0.4mm to 0.5mm).
1.2 Identifying the Distributor
Locating your distributor is the first step. It’s usually a cylindrical component atop the engine, attached to the distributor cap with high-voltage wires leading to each spark plug. Consult your vehicle’s repair manual for precise location if you’re uncertain.
2. Gathering the Necessary Tools
Before starting any work on your vehicle’s ignition system, gather the necessary tools:
- Distributor point gap tool: This specialized tool ensures precise gap measurement and adjustment. Don’t substitute with a regular feeler gauge.
- Screwdriver (likely Phillips): For adjusting the point screw.
- Wrench (size varies): To loosen and tighten the distributor hold-down clamp (if needed).
- Timing light: For verifying point timing after adjustment. While not strictly necessary for gap adjustment, it’s invaluable for ensuring optimal ignition timing.
- Repair manual: The definitive source for specific procedures and specifications for your vehicle.
- Safety Glasses and Gloves: Protecting yourself is paramount.
3. Setting Up for Distributor Points Adjustment
3.1 Safety First!
Disconnect the negative battery terminal before commencing any work on your ignition system. This is a crucial safety precaution to prevent accidental shocks or damage to electronic components.
3.2 Accessing the Points
Remove the distributor cap carefully. Locate the distributor points, usually a small pair of contacts near the rotor. The adjustment screw will be visible next to the points.
4. The 5-Step Distributor Points Adjustment Process
- Measure the existing gap: Using the distributor point gap tool, carefully measure the gap between the points.
- Adjust the gap: Gently turn the adjusting screw to widen or narrow the gap until it matches the specified gap in your repair manual. Small adjustments make a big difference.
- Re-measure: Double-check the gap with the gap tool. Slight adjustments might be necessary for perfect accuracy.
- Check for point bounce: Carefully operate the distributor’s cam. If the points chatter or bounce, the gap is too loose. Readjust as necessary.
- Reinstall the distributor cap: Reconnect the battery and carefully reinstall the distributor cap, ensuring the rotor aligns correctly with the distributor cap terminals.
5. Verifying Point Timing (Optional but Recommended)
While this guide focuses on gap adjustment, proper timing is equally crucial. Use a timing light to visually check ignition timing and adjust the distributor’s position slightly to achieve optimal timing as per your vehicle’s specifications. Refer to your vehicle’s repair manual for detailed timing instructions. Incorrect timing can negate the benefits of a correctly adjusted point gap.
6. Troubleshooting Common Issues
6.1 Points Burning
Frequently burned points suggest other problems, such as a faulty condenser or coil. Address these underlying issues before repeatedly adjusting the points.
6.2 Engine Misfires
Misfires may indicate the point gap is incorrect (too wide or too narrow), point bounce, or another ignition system problem including issues with spark plugs, plug wires, and the coil.
6.3 Difficulty Starting
Difficult starting can be due to a variety of factors — including the distributor points adjustment; however, a weak battery, faulty starter, or carburetor issues are far more common culprits.
7. Maintaining Your Distributor
Regular maintenance, including periodically checking and adjusting the distributor points, is essential for prolonging the life of your ignition system and ensuring optimal performance. Consider this more of a preventative measure than reactive repair. Replacing the points and condenser is usually advisable at regular service intervals, as stated in your vehicle’s service manual.
8. Alternative Ignition Systems
Many modern vehicles utilize electronic ignition systems, eliminating the need for points entirely. This guide applies specifically to older vehicles with mechanical distributor systems. Trying to adjust points on a vehicle not designed for them will likely cause damage.
FAQ
Q1: How often should I adjust my distributor points?
A1: The frequency depends on your vehicle and driving conditions. However, it’s generally recommended to check and adjust them every 6 months or 6,000 miles (9656 km) or as stated in your service manual. Regular inspections are key to preventing problems.
Q2: Can I use a regular feeler gauge instead of a points gap tool?
A2: It’s not recommended. A standard feeler gauge might damage the delicate points. A specialized distributor point gap tool is designed for this specific purpose and ensures accurate measurements.
Q3: What happens if the distributor points gap is too wide?
A3: A gap that’s too wide will result in weak sparks, leading to rough idling, misfires, decreased power, and even engine damage.
Q4: My points keep burning. What should I do?
A4: Recurring point burning suggests a condenser failure which should be replaced immediately. A shorted condenser provides continuous current causing the points to overheat and burn up.
Q5: Where can I find a service manual for my specific vehicle?
A5: You can often find online resources or dealerships that sell service manuals for specific vehicle makes and models. Haynes Manuals and Chilton Manuals are two reputable online sources for vehicle repair manuals.
