Ignition Contact Set Replacement for the 1971-1973 International 1010
Understanding and replacing the ignition points in your classic International truck to ensure reliable starting and smooth running.
- The ignition contact set (points) is a common wear item; symptoms of failure include no-start, rough running, and stalling.
- For IH V8 engines, remember that ignition timing is set using cylinder #8, not #1.
- Use a feeler gauge to set the point gap correctly (typically 0.019"-0.022") for your distributor.
- Standard Ignition is a trusted aftermarket brand for this part, as new OEM parts are no longer made.
Is Your International 1010 Ignition Contact Set Failing?
After 50+ years of service, the original ignition points in your truck are well past their expected lifespan. Because they are a mechanical part with a rubbing block that rides on the distributor cam, they wear down over time. The electrical contacts can also become pitted or burned, leading to a weak or inconsistent spark. This can cause a range of frustrating performance issues that can be mistaken for bigger problems.
Common Symptoms of Bad Ignition Points
- Hard Starting or No-Start: This is the most common sign. Worn or misaligned points can't create the strong, consistent spark needed to fire up the engine.
- Engine Misfires and Rough Idle: Pitted or dirty points cause an erratic spark, leading to an engine that shakes, stumbles, or runs unevenly.
- Stalling: The engine may stall, especially at idle or when coming to a stop, because the weak spark can't keep the engine running at low RPMs.
- Reduced Power and Sluggish Acceleration: A weak spark means inefficient combustion, causing the engine to feel sluggish and hesitant when you press the gas pedal.
Choosing the Right Aftermarket Ignition Contact Set
For a classic truck like the 1010, finding new original equipment (OEM) parts from International Harvester is nearly impossible. The aftermarket is your only viable source for a new ignition contact set. Fortunately, established brands have been making these parts for decades.
Brand Quality: Standard Ignition
Standard Ignition (often sold as Standard or their premium Blue Streak line) is a well-regarded aftermarket brand with a long history of making quality ignition components for American vehicles. In forums for classic cars and tractors, owners often recommend Standard as a reliable choice for points and condensers. While the quality of all modern points can be inconsistent compared to decades ago, Standard remains one of the most trusted options available today.
A Note on Condensers
The ignition contact set works with a condenser, which prevents the points from arcing and burning out prematurely. Most new contact sets come with a new condenser. However, the quality of modern condensers is a frequent topic of debate among classic vehicle owners. Some mechanics advise that if your old, original condenser is still working, it may be more reliable than a new one. Unfortunately, new-old-stock (NOS) condensers are not always a good solution, as they can degrade over time just from sitting on a shelf.
Typical Costs for a New Ignition Contact Set
Replacing the ignition contact set is one of the more affordable maintenance jobs for your truck. The parts are inexpensive, and if you do it yourself, the only cost is the part and your time.
| Part Type | Price Range |
|---|---|
| New Aftermarket (Standard Ignition) | $18.51 - $37.15 |
| Shop Labor | $60 - $120 |
Frequently Asked Questions (FAQ)
How often should I replace my ignition points?
As a general rule for older vehicles, ignition points should be inspected and adjusted every tune-up, and replaced roughly every 10,000 to 15,000 miles. Since they are inexpensive, it's good practice to replace them whenever you replace your spark plugs and distributor cap.
What is the correct point gap for a 1971-1973 International 1010?
The exact gap depends on the distributor in your truck (often a Holley or Prestolite). A common setting for IH V8 engines is around 0.019 to 0.022 inches. Always use a feeler gauge to set the gap when the points' rubbing block is on the highest point of the distributor cam lobe. An incorrect gap can prevent the engine from starting or cause it to run poorly.
Can I upgrade to electronic ignition?
Yes, many owners of International trucks choose to replace their points and condenser system with an electronic ignition conversion kit (like those from Pertronix). These kits eliminate the need for points, offering a more reliable spark and reducing maintenance. However, a properly functioning points system is very effective and original to the truck.
Is a dwell meter required for installation?
A dwell meter is not strictly required, but it is the most accurate way to set the points while the engine is running. The alternative, and more common DIY method, is to set the gap with a feeler gauge with the engine off. For most owners, a feeler gauge is sufficient to get the truck running well.
