Tools You'll Need:
* Socket set and wrenches: Various sizes, including those for the distributor hold-down clamp.
* Screwdriver: Phillips head likely needed for some components.
* Distributor installation tool (optional but recommended): This helps align the distributor accurately.
* Timing light: Essential for setting the ignition timing correctly after installation.
* Rags or shop towels: To keep things clean.
* Safety glasses and gloves: Protect yourself!
* New distributor: Obviously. Make sure it's the correct one for your 351 engine.
Procedure:
1. Disconnect the Battery: This is crucial to prevent accidental shorts and injury. Disconnect the negative (-) terminal first.
2. Remove the Distributor Cap and Rotor: Carefully remove the distributor cap and rotor, noting the position of the rotor in relation to the cap. This helps with reassembly.
3. Mark the Distributor's Position: Before removing the distributor, carefully mark its position relative to the engine block. Use a piece of tape or a paint marker to note its orientation. This is critical for proper timing.
4. Loosen the Distributor Hold-Down Clamp: Locate the clamp securing the distributor to the engine block. Carefully loosen and remove it.
5. Remove the Distributor: Gently wiggle the distributor while pulling it straight up. It may be slightly stiff, but avoid forcing it.
6. Install the New Distributor: This is the most crucial step.
* Alignment: Carefully align the distributor according to your markings from step 3 and/or using the distributor installation tool. The distributor shaft should engage properly with the oil pump drive.
* Install the distributor: Carefully lower the new distributor into place, ensuring it's seated correctly and engaging the drive shaft.
* Tighten the Hold-Down Clamp: Securely tighten the hold-down clamp, but don't overtighten.
7. Install the Rotor and Cap: Replace the rotor and distributor cap, ensuring they are properly aligned.
8. Reconnect the Ignition Wiring: Carefully reconnect all the ignition wires to the distributor cap. Make sure each wire goes to the correct terminal.
9. Reconnect the Battery: Reconnect the battery's negative (-) terminal.
10. Set the Ignition Timing: This is absolutely essential. Use a timing light to set the ignition timing according to your engine's specifications (found in your repair manual). This usually involves adjusting the distributor slightly.
11. Test the Engine: Start the engine and check for proper operation. Listen for any unusual noises and look for any leaks.
Important Considerations:
* Vacuum Advance: Many distributors have a vacuum advance mechanism. Make sure it's connected correctly.
* Distributor Gear: Check the distributor gear for wear. If it's worn, replace it as well to avoid future problems.
* Repair Manual: A repair manual specific to your 1976 Ford 351 engine is invaluable for detailed instructions, torque specifications, and wiring diagrams.
This is a simplified guide. If you are not comfortable performing this task, it's best to seek the help of a qualified mechanic. Incorrect installation can lead to serious engine damage. Remember safety first!
