Signs of a Failing Distributor Cap
A distributor cap is a part that wears out. The high voltage and heat from the engine can cause the plastic to crack and the metal terminals inside to corrode. When this happens, your truck will let you know. Watch for these common symptoms:
- Engine Misfires: The engine may stumble, shake, or hesitate when you accelerate. This is a classic sign that a cylinder isn't firing correctly.
- Hard Starting: Your truck may take longer than usual to start, or it might just crank without turning over. This can be worse in damp weather, as moisture can get inside a cracked cap.
- Rough Idle: The engine may run unevenly or feel shaky when you're stopped. This can be caused by a weak or inconsistent spark.
- Stalling: A badly worn cap can interrupt the spark completely, causing the engine to stall unexpectedly.
Is an Original OEM Cap Available?
Since Studebaker stopped making vehicles in the 1960s, you cannot buy a "new OEM" distributor cap from the factory. Any new cap you find today is an aftermarket reproduction. The only "original" option is New Old Stock (NOS), which are vintage parts that were never sold. NOS parts are rare, expensive, and not necessary for a reliable driver. Modern aftermarket caps are the standard, reliable choice for these trucks.
Choosing the Right Aftermarket Cap
For the 1961 6E13D with a V8 engine, new aftermarket distributor caps are readily available from brands like Standard Ignition and Walker Products. These caps are designed for the Delco-style distributor used in your truck.
- Standard Ignition: Often considered a quality replacement brand with a long history. Their caps typically feature brass terminals, which resist corrosion better than aluminum. Some classic car owners suggest inspecting any new cap before installation to ensure there are no defects from manufacturing.
- Walker Products: Another established aftermarket manufacturer that produces a wide range of ignition components. They market their parts as meeting or exceeding original specifications.
Pro Tip: When choosing a new cap, look for one with brass terminals. Brass is a better conductor and is more resistant to corrosion and pitting than the aluminum terminals found on some budget-friendly options. Also, always replace the distributor rotor at the same time as the cap. The rotor wears at the same rate and is essential for a complete tune-up.

Frequently Asked Questions (FAQ)
Is replacing the distributor cap a DIY job?
Yes, this is a very easy job for a DIY mechanic. The cap is held on by two clips. The only tools you need are your hands and maybe a screwdriver. The key is to move the spark plug wires from the old cap to the new cap one at a time to keep the correct firing order. The entire job takes less than 30 minutes.
What is the firing order for the Studebaker V8?
The firing order for the Studebaker V8 is 1-8-4-3-6-5-7-2. The distributor rotates counter-clockwise. The cylinders are numbered 1-3-5-7 on the driver's side and 2-4-6-8 on the passenger side.
Do I need to replace the rotor with the cap?
Yes, you should always replace the distributor rotor when you replace the cap. The rotor is the spinning part inside the cap that actually transfers the spark. It wears out just like the cap does, and a new cap with an old rotor will not perform well.
Were there any recalls for the 1961 Studebaker truck distributor cap?
No. There are no recalls or Technical Service Bulletins (TSBs) on file with the NHTSA for the ignition system on this vehicle. Recalls for specific components on vehicles from this era are extremely rare in modern databases.
