Checking Compatibility
It’s critical to ensure your chosen HEI distributor is compatible with your engine. Incorrect selection can lead to performance issues or even damage. Always verify compatibility using the manufacturer’s specifications or consult a trusted auto parts professional.
2. Removing the Old Distributor
Carefully remove your old distributor. This usually involves:
- Disconnecting the Spark Plug Wires: Number them meticulously; a misfire can be prevented by installing them in the correct firing order.
- Removing the Distributor Cap: Unscrew and set aside.
- Loosening the Distributor Hold-Down Clamp: Carefully release the distributor clamp and remove it.
- Rotating the Distributor: Carefully rotate the distributor slightly to break the distributor shaft from the engine.
- Lifting Out the Distributor: Remove the old distributor, paying attention to any potential obstructions or interference.
Protecting Components
During the removal process, protect sensitive components, such as the ignition coil and wiring, to prevent damage during the HEI distributor installation.
3. Preparing the Engine for the New Distributor
Before installing the HEI distributor, it’s crucial to prepare the engine to ensure proper alignment and installation.
- Checking for Debris: Remove any debris or dirt that could prevent proper seating.
- Inspecting the Distributor Shaft: Make sure the distributor shaft is clean and free of damage. This is important for a smooth HEI distributor installation.
- Lubricating the O-Ring (if present): This prevents leaks and facilitates better seating.
4. Installing the New HEI Distributor
With the engine prepared, carefully install the new HEI distributor.
- Aligning the Distributor: Carefully align the distributor according to the timing marks on the engine block and harmonic balancer. This step is crucial for HEI distributor installation success. Use your distributor installation tool if you have one.
- Installing the Distributor: Gently insert the distributor, making sure it seats properly. Avoid forcing it.
- Securing the Distributor: Tighten the hold-down clamp securely.
- Connecting the Wires: Carefully connect the spark plug wires to the correct terminals, following the firing order.
- Connecting to the Coil and Power: Connect the power wire and the signal wire to your HEI distributor.
Precise Alignment
Accurate alignment is paramount. A misaligned distributor will lead to poor engine performance and poor fuel economy. Reference your vehicle’s repair manual for specific timing marks.
5. Setting the Ignition Timing
Once the HEI distributor is installed, you need to set the ignition timing. This step ensures optimal engine performance.
- Use a Timing Light: Connect it correctly per instructions.
- Follow your vehicle’s specifications: Consult your owner’s manual for the correct timing setting.
- Adjust the Distributor: Carefully adjust the distributor for proper timing.
