How to Install a Distributor Rotor and Cap

Both the distributor and rotor are subject to wear and tear. It's estimated that the rotor will make approximately 45 million revolutions during 30,000 miles. This causes the contacts to wear out and need replacing. Keep in mind the following guidelines to ensure proper installation of the distributor rotor and cap.

Difficulty: Moderately Challenging

Instructions

Things You'll Need:

• Blue Loctite
• Dielectric grease or Anti-seize

1. Place the distributor in its proper position by popping it on. Some rotors may have a small retaining bolt going through one of the sides. Notice the distinct shape of the router. It goes in only one way; all you have to do is slide it on to install it.

2. Use a small amount of Blue Loctite (adhesive to keep bolts from coming loose) if the router has a retaining bolt. Apply enough Loctite to cover only half of the thread portion on the bolt.

3. Slide the cap over the ignition coil probe. It's important that you install it properly. Make sure the small rubber gasket isn't compromised; its purpose is to keep moisture and contaminants out. Any bit of moisture can cause problems, like making your vehicle run funny or even preventing it from starting. Everything must seat properly.

4. Put all the bolts in first and then go back and tighten them; this way you can ensure that all the holes line up. Tightening one bolt down will cause the distributor to cock to one side and make installation of the other bolts more challenging.

5. Apply compound on these bolts to keep them from sticking together. It will make taking them apart much easier. Use dielectric grease or a compound called Anti-seize. This is a metallic-looking compound that looks like silver paste.

Tips & Warnings

• Do not use Red Loctite on the bolts, or you'll never be able to remove them.
