Pre-view: What Is A MSD Distributor

The MSD distributor is not just a small part of your car's ignition system, for those who pursue performance owners, it is simply an artifact. This distributor is made of fine quality, to ensure that every ignition is accurate, which is essential to improve the engine power and efficiency. This high-performance distributor, whether you're driving a new car or an old car, can handle it, with many features, such as adjusting the ignition time, using advanced magnetic sensors, ignition energy is also stronger, so that the combustion is cleaner.

Whether you want to increase horsepower, improve fuel efficiency, or give your engine a new look, the MSD distributor delivers the reliability and performance you need. With its advanced technology and easy installation, it's no wonder that racers, mechanics and car enthusiasts all over the world use it.

Two types of MSD Distributor[An Introduction]

There are two main types of MSD distributor, each designed for different performance and vehicle configurations: one is a Ready-to-Run Distributor and the other is a Pro-Billet Distributor.

Ready-to-Run Distributors

As the name suggests, Ready-to-Run (RTR) distributors are simple to install and ready to go. This distributor is especially suitable for those who want to upgrade the ignition system, but do not want to get an external ignition box. It comes with an ignition module, ignition energy is stable, time is accurate, installation is also simple, on three lines. This distributor is most suitable for ordinary street cars or slightly modified cars, plug in can improve the performance, especially convenient.

Pro-Billet Distributors

If you want to pursue the ultimate performance, maximum ignition control, then Pro-Billet Distributor is the way to go. The distributor uses a high-quality aluminum housing and advanced magnetic sensors, designed for the high demands of racing or high-performance street cars. Unlike plug-and-play models, professional-grade aluminum distributors need an external ignition box, such as MSD 6AL, to work. As a result, it can be fine-tuned and the ignition energy is stronger, ensuring optimal performance even in extreme conditions.

Complete Installation Walkthrough: MSD Distributor

Installing an MSD distributor is a straightforward process when you follow the steps carefully. Below is a step-by-step walkthrough to help you confidently install your MSD distributor and optimize your engine’s performance.

Step 1: Preparation

1. Disconnect the Battery

   • For safety, disconnect the negative battery terminal to prevent accidental electrical shorts.

2. Set the Engine to Top Dead Center (TDC)

   • Rotate the crankshaft until the #1 cylinder is at TDC on the compression stroke. Use a timing mark on the harmonic balancer and the timing tab as a reference.

3. Mark the Rotor Position

   • Before removing the old distributor, mark the rotor position and the location of the distributor base on the engine to use as a reference during installation.

Step 2: Remove the Old Distributor

1. Disconnect Wiring

   • Unplug all electrical connectors and label them if necessary for reconnection.

2. Remove the Distributor Hold-Down Clamp

   • Use a distributor wrench to loosen and remove the hold-down clamp.

3. Lift Out the Distributor

   • Carefully pull the distributor straight up to avoid damaging the gear or surrounding components.

Step 3: Install the New MSD Distributor

1. Inspect the New Distributor

   • Ensure the distributor gear is properly lubricated and the gasket is installed at the base of the distributor.

2. Align the Rotor

   • Position the rotor to match the marked position from the old distributor. The rotor will rotate slightly as the gear meshes with the camshaft, so align it accordingly.

3. Install the Distributor

   • Insert the new distributor into the engine block. Ensure the distributor shaft fully seats into the oil pump drive. If necessary, slightly rotate the rotor or crankshaft to align the components.

4. Secure the Distributor

   • Reinstall the hold-down clamp and tighten it lightly, leaving some play to adjust timing later.

Step 4: Connect Wiring

1. Connect the Ignition Wires

   • Attach the distributor’s wiring harness to the coil, ignition box (if required), and other necessary components. Follow the wiring diagram provided with your MSD distributor.

2. Reconnect the Spark Plug Wires

   • Attach the spark plug wires to the distributor cap in the correct firing order. Double-check your vehicle’s firing order in the service manual.

Step 5: Set the Timing

1. Initial Timing Adjustment

   • Rotate the distributor housing slightly to align the rotor with the #1 cylinder’s terminal on the distributor cap.

2. Start the Engine

   • Reconnect the battery, start the engine, and use a timing light to check the timing. Adjust the distributor to achieve the recommended initial timing setting for your engine.

3. Secure the Distributor

   • Once the timing is set, tighten the hold-down clamp securely to lock the distributor in place.

Step 6: Final Checks

1. Recheck Timing

   • Verify the timing once more to ensure it hasn’t shifted while securing the distributor.

2. Test the Engine

   • Run the engine at various RPMs to confirm smooth operation and proper ignition performance.

3. Inspect for Leaks or Loose Connections

   • Check for oil leaks around the distributor base and ensure all electrical connections are secure.

Tools for Installing A MSD Distributor[What you need to prepare]

Basic Hand Tools

• Socket Set and Ratchet: Used to remove and tighten bolts, such as those on the distributor hold-down clamp and other components.

• Screwdrivers: Required for loosening or securing hose clamps, electrical connections, or screws during installation.

• Distributor Wrench: A specialized tool that makes it easier to loosen and tighten the hold-down clamp in tight spaces.

Timing Light

• A critical tool for setting the ignition timing accurately. It flashes in sync with the spark plug firing, allowing you to adjust the distributor to the correct timing marks on the engine.

Marking Pen

• Used to mark the original position of the rotor and distributor before removal. This helps ensure proper alignment during installation and prevents timing issues.

Gasket Sealant

• Ensures a secure and leak-free seal between the base of the distributor and the engine block. This prevents oil leaks that could affect engine performance.

Distributor Hold-Down Clamp

• A small but essential part that keeps the distributor securely in place. It’s important to check that it’s properly tightened to maintain consistent timing.

Optional: MSD Ignition Box

• If your MSD distributor requires an external ignition box, such as the MSD 6AL, this tool will amplify spark energy and allow for advanced tuning options.

FAQs: How many Volts Does A MSD Distributor Need

An MSD distributor itself doesn't require a specific voltage as it is a mechanical component. However, the ignition system it works with typically needs 12 volts from the vehicle's battery. If you're using an external MSD ignition box (e.g., MSD 6AL), it requires a stable 12-volt input for proper operation. Always refer to the manufacturer’s specifications for exact requirements.

Final Verdict

Installing an MSD distributor is a simple yet rewarding process that enhances engine performance. With the right tools, careful preparation, and precise timing, you can complete the installation confidently and enjoy the benefits of a reliable ignition system.
