Ignition Contact Set Guide for the 1949 Studebaker 2R11
Keep your classic Studebaker truck running smoothly by understanding this critical tune-up part.
- The ignition contact set (points) is a normal wear item that requires periodic replacement, typically every 10,000-12,000 miles.
- For the 1949 Studebaker 2R11 Champion engine, the correct point gap is a critical .020 inches.
- Always replace the condenser at the same time as the points to ensure the longevity and reliability of the ignition system.
- A quality aftermarket brand like Standard Ignition is the reliable and standard choice, as new OEM parts are no longer produced.
Signs of a Failing Ignition Contact Set
Ignition points are a normal wear item, just like brake shoes or tires. The constant opening and closing, along with the electrical arc, causes the contact surfaces to pit and burn over time. The small rubbing block that rides on the distributor cam also wears down. When your 2R11's ignition points start to fail, you'll notice some clear symptoms:
- Engine Misfires: Worn, pitted, or dirty points can cause an inconsistent spark, leading to the engine running rough, stumbling, or shaking, especially under acceleration.
- Hard Starting or No Start: If the points are not making good contact or are completely burned out, they can't trigger the coil to create a strong spark, or any spark at all. The engine may crank but fail to start.
- Reduced Power and Poor Performance: Incorrectly gapped or worn points can lead to a weak spark, resulting in poor fuel economy and a feeling that the truck is sluggish or lacking power.
- Stalling: As the points degrade, they may fail to deliver a consistent spark at low RPMs, causing the engine to stall at idle or when coming to a stop.
Choosing the Right Aftermarket Part
For a vintage vehicle like the 1949 Studebaker 2R11, original OEM parts from Studebaker are no longer in production. The market is served by established aftermarket manufacturers. For ignition components, Standard Ignition (a brand of Standard Motor Products or SMP) is a well-known and reliable choice. They have been producing ignition parts for decades and are a common go-to for classic American vehicles. For this application, a quality aftermarket part is not just an option; it's the standard for keeping these trucks on the road.
Estimated Part & Labor Costs
| Part Type | Price Range |
|---|---|
| New Aftermarket (Standard Ignition) | $21.53 |
| Shop Labor | $100 - $200 |
Note: Labor costs are estimates and can vary based on shop rates and location. Finding a mechanic experienced with vintage ignition systems is recommended.
Pro Tip: Check and Set the Gap
The single most critical step of installation is setting the correct point gap. For the Studebaker Champion engine used in your 2R11, the correct distributor point gap is .020 inches. This measurement must be taken when the points' rubbing block is on the highest point of a lobe on the distributor cam. Use a feeler gauge for accuracy. An incorrect gap will cause poor performance and can lead to premature failure of the points.
Known Issues, Recalls, and TSBs
There are no specific recalls or Technical Service Bulletins (TSBs) from the National Highway Traffic Safety Administration (NHTSA) for the ignition contact set on a 1949 Studebaker 2R11. This is expected for a vehicle of this age. The primary issues are related to normal wear and tear. It is a standard maintenance part that was expected to be replaced at regular tune-up intervals, typically every 10,000-12,000 miles.
Frequently Asked Questions (FAQ)
Should I replace the condenser at the same time?
Yes, it is highly recommended. The condenser is a small capacitor that absorbs excess voltage to prevent the points from arcing and burning out too quickly. Since they work together and are located in the same place, it is standard practice to replace them as a set.
What tools do I need to replace the ignition points?
You will need basic hand tools like a screwdriver and small wrenches to access the distributor. The one special tool required is a feeler gauge to set the point gap correctly. A dwell meter can also be used for a more precise adjustment, but a feeler gauge is sufficient for a DIY replacement.
What is the difference between points and electronic ignition?
Points are a mechanical switch that physically opens and closes to trigger the spark. Electronic ignition systems, which became common in the 1970s, use a sensor and a control module to do the same job without any moving contacts. While some owners convert to electronic systems, a properly maintained points system is very reliable.
What is the correct point gap for my 1949 Studebaker 2R11?
The correct point gap for the Champion engine in your truck is .020 inches. This is a critical specification for proper engine timing and performance.
