Installation Process
A Pro Comp distributor installation process varies depending on the engine’s make and model and the type of distributor. However, here are the general steps you need to follow:
Step 1: Preparation
Before you begin the installation process, you need to gather the necessary tools and equipment, including a Pro Comp distributor kit, a spark plug gap tool, a timing light, a wrench or socket set, and a spark plug wire removal tool. Also, make sure the engine is cool and the battery is disconnected to prevent any electrical shock or accidental startup.
Step 2: Remove the Old Distributor
If you are replacing an old distributor, you need to remove it first. To do that, you need to locate the distributor’s position and mark it with a paint marker or masking tape to help you align the new distributor correctly. Then, remove the distributor cap and rotor, disconnect the spark plug wires, and loosen the distributor’s hold-down bolt with a wrench or socket set.
Step 3: Install the New Distributor
Once you have removed the old distributor, you can install the new Pro Comp distributor. To do that, you need to align the distributor rotor with the engine’s timing mark and insert the distributor shaft into the engine’s oil pump drive. Then, tighten the hold-down bolt and install the distributor cap and rotor. Finally, connect the spark plug wires according to the correct firing order and connect the wiring harness.
Step 4: Set the Ignition Timing
After you have installed the new distributor, you need to set the ignition timing using a timing light. To do that, you need to start the engine and let it warm up to operating temperature. Then, connect the timing light to the number one spark plug wire and adjust the distributor’s advance until the timing mark on the crankshaft pulley aligns with the timing tab on the engine block. Once you have set the timing, tighten the distributor hold-down bolt and recheck the timing with the timing light.
