Accessory Drive Belt Guide for the 1963-1964 Studebaker 8E12D Truck
Keep your classic Studebaker truck running strong by understanding its essential accessory drive belts.
- Your truck uses one or more V-belts, not a modern serpentine belt; squealing, cracking, and accessory failure are key signs of wear.
- Modern aftermarket brands like Dayco, Gates, and Continental are superior and more reliable than any New Old Stock (NOS) OEM belts.
- Replacement is an affordable and simple DIY job for most owners with basic tools.
- The most common cause of failure is incorrect tension (too loose) or simple old age; always check tension after installing a new belt.
Signs of a Failing Accessory Drive Belt
A worn or failing V-belt on your Studebaker truck will give you clear warning signs. Ignoring these symptoms can leave you stranded with an overheated engine or a dead battery. Be on the lookout for the following:
- Squealing Noises: This is the most common symptom. A loud, high-pitched squeal, especially when you start the engine or accelerate, is caused by a loose or worn belt slipping on the pulleys.
- Visible Damage: Regularly inspect your belts. Look for cracks on the underside, fraying edges, missing chunks, or a shiny, hardened appearance known as glazing. Any of these signs mean the belt is old and needs to be replaced. 🎬 Learn how to spot visual signs of a worn belt.
- Accessory Failure: If the "GEN" light on your dashboard comes on, it could mean the belt is slipping and not turning the generator fast enough to charge the battery. Similarly, if your engine temperature starts to rise, the belt may not be turning the water pump effectively.
- Vibrations: A belt that is stretched, damaged, or has missing pieces can cause unusual vibrations that you might feel as it rotates. 🎬 Watch this video to see common drive belt failure signs.
Choosing the Right Aftermarket Belt
Finding an original "OEM" Studebaker belt is not practical, as the company stopped production decades ago. Even if you found a New Old Stock (NOS) belt, its rubber would likely be brittle and unreliable from age. Modern aftermarket belts are the best choice, as they are made from superior materials that are more resistant to heat, oil, and cracking.
For your 1963-1964 Studebaker 8E12D, reputable brands like Gates, Dayco, and Continental are all excellent, reliable choices. Forum discussions among classic car owners show that these brands are widely used and trusted. The most important factor is ensuring you get the correct size and type of belt for your truck's specific configuration (with or without power steering, etc.).

Pro Tip: Check Your Pulleys
When you replace your belts, take a moment to inspect the pulleys they ride on. Worn or damaged pulleys can quickly destroy a new belt. Make sure they are clean, spin freely without wobbling, and don't have any significant wear or damage in the grooves.
Frequently Asked Questions (FAQ)
How often should I replace the accessory drive belts?
If you don't know how old the belts are, it's best to replace them. For preventative maintenance, a good rule of thumb is to inspect them at every oil change and consider replacement every 3-5 years or around 25,000 miles, as rubber degrades over time regardless of mileage.
Can I replace the belts myself?
Yes, this is a very DIY-friendly job on a classic truck like the Studebaker 8E12D. The process typically involves loosening the generator (or other accessory) to create slack, swapping the belt, and then re-tensioning it. It usually only requires basic hand tools.
What is a V-Belt?
A V-belt is a type of drive belt with a trapezoidal or "V" shape. This shape helps it wedge into the groove of a pulley, increasing friction and allowing it to transmit power effectively. Your Studebaker uses this older, reliable style of belt instead of a modern, flat serpentine belt.
What causes a new belt to squeal?
A new belt usually squeals for two main reasons: improper tension (usually too loose) or contamination from oil or grease on the pulleys. It can also be a sign of misaligned pulleys. Always make sure the pulleys are clean and the belt is tensioned correctly after installation.
A Note on Recalls and Service Bulletins
There are no active recalls or Technical Service Bulletins (TSBs) from the NHTSA for accessory drive belts on the 1963-1964 Studebaker 8E12D. Issues with belts on these vintage trucks are almost always due to normal wear, age, incorrect tension, or contamination from fluid leaks.
