Gather Necessary Tools
To get started with cleaning and adjusting the distributor points in a classic Chrysler, make sure you have the right tools. Here's what you need:
- Feeler Gauge: This helps measure the gap between the distributor points. The gap should match what the manufacturer says, usually around 0.017 inches for many classic Chrysler cars.
- Screwdriver Set: A flat-head screwdriver is handy for adjusting the screws that hold the points.
- Dwell Meter: This tool checks the angle the distributor cam opens the points. It's for more precise tuning.
- Clean Rags and Contact Cleaner: Use lint-free rags and a special cleaner for electrical parts to wipe away dirt or rust from the points.
- Ignition File: Although old-fashioned, this tool is great for lightly filing the points if they're pitted or have residue.
- Timing Light: This confirms that your adjustments haven't changed the ignition timing, keeping your car running smoothly.
Having these tools ready will make the job easier and help you do it right.
Ensure Safety Precautions
Before you start cleaning and adjusting the distributor points on your classic Chrysler, focus on safety. First, disconnect the car's battery to avoid any electrical shocks. Classic Chrysler cars have different electrical systems, so make sure to do this step. Use a wrench to take off the negative terminal cable, and keep metal objects away from the battery.
Wear gloves and goggles to protect yourself from harmful substances or dirt. The area around the distributor can be greasy or dusty. Pick gloves that can handle oils and chemicals well so you can hold tools firmly.
Make sure your workspace has good airflow. Cleaning agents can produce dangerous fumes if inhaled in closed spaces. If you're working inside, open windows and use fans to keep the air moving.
Put wheel chocks around the tires to stop the car from moving while you work. Classic cars may not have modern safety features, so keeping the car stable is important.
Keep a fire extinguisher nearby in case of an electrical fire. It's rare, but it's smart to be ready. Following these tips will help you work safely with the distributor points on your classic Chrysler.
Locate the Distributor
To keep your classic Chrysler running smoothly, you'll need to find the distributor. This part helps send electricity from the ignition coil to the spark plugs. Where the distributor sits can vary based on your car's model and engine type, but it's usually on the engine itself.
Here's how to find it:
- Check the Service Manual: Look at your car's service manual for diagrams that show where the distributor is.
- Look Under the Hood: Pop the hood and take a look at the engine. The distributor is often near the top, attached to the engine block or cylinder head.
- Follow the Spark Plug Wires: Trace the wires from the spark plugs back to the distributor cap. These wires will lead you right to it.
Finding the distributor is the first step in keeping your engine in good shape.
Remove Distributor Cap
First, make sure the car is off and the keys are out.
Find the distributor cap, which is usually held on by two to four screws or clips. Use a screwdriver that fits the screw head, which might be Phillips or flat-head. If there are clips, use a flat-head screwdriver to gently open them.
Before taking off the cap, note how it fits onto the distributor. Some people use a marker to help remember the position for putting it back on later.
Once the screws or clips are loose, carefully lift the cap. Be gentle to avoid moving the rotor inside. The cap has terminals that line up with spark plug wires, so don't yank the cap off.
After removal, set the cap aside in a way that you can easily put it back later.
Inspect the Points
Remove the distributor cap to check the ignition points. These points are key for your classic Chrysler's engine to work well.
- Check for Pitting: Look for small craters or rust on the contact surfaces. These can make the engine misfire or run unevenly, showing that the points need to be changed.
- Align the Contacts: See if the contacts are lined up correctly. Bad alignment can cause poor contact and irregular sparks. Make sure the points open and close evenly. Use a feeler gauge to measure the gap when the points are open.
- Surface Condition: Look for wear, burnt spots, or rust. These can block electricity and hurt engine performance.
- Spring Tension: Check if the spring is tight enough to keep the points closed. A weak spring can cause bouncing and ignition problems.
- Pivot Point Wear: See if there's wear where the arm pivots. Too much wear can change the gap and affect engine timing.
Go through each part to make sure the ignition system works well.
Clean the Contact Points
To keep your classic Chrysler running well, make sure the contact points are clean. These points help the ignition system work by letting electricity flow at the right time.
Start by disconnecting the battery to avoid any shocks. Then, use a screwdriver to take off the distributor cap so you can reach the points. Look for any dirt or carbon build-up on them.
Use 220-grit sandpaper to gently clean the points until they shine and are free from dirt. You can also use a points file, which keeps the surface flat while cleaning.
After sanding, wipe them with a clean cloth to remove leftover dust. If they are really dirty, spray a little electrical contact cleaner on them. It dries fast and doesn't leave anything behind.
Once everything is clean, put the distributor cap back on tightly. Keeping the contact points clean helps your car run smoothly.
Adjust the Gap
After cleaning the contact points in your classic Chrysler's ignition system, check the gap between them. This gap affects how well the engine runs. Usually, it should be set between 0.017 to 0.021 inches for many older Chrysler models. If the gap is wrong, the engine might not run smoothly or start easily.
Here's how to adjust the gap:
- Turn the Engine: Turn the engine by hand until the distributor cam is at the highest point on one of the lobes. This is where you measure the gap.
- Check the Gap: Use a feeler gauge to measure the space between the points. The gauge should fit snugly without being forced.
- Adjust the Gap: Loosen the screw holding the points in place. Adjust the points to get the right gap, then tighten the screw so it stays set.
Following these steps helps keep your classic Chrysler's engine running well.
Reassemble and Test
First, put the rotor back on the distributor shaft. Make sure it lines up with the screw or clip that holds it in place.
Then, place the distributor cap over the rotor. Check that there are no gaps and that it fits snugly. Look for the notches or grooves to make sure the cap is lined up with the distributor housing.
Tighten the screws according to the manufacturer's torque settings. This helps avoid damage from over-tightening and keeps everything secure.
Reattach the ignition wires to the right terminals on the distributor cap. Double-check that the firing order matches the engine's needs.
After everything is back together, start the engine. Listen to see if it idles smoothly and runs well. Use a timing light to check the ignition timing. Make sure it matches what the vehicle needs. If not, go back and check your work.
For more checking, take the car for a drive. Pay attention to how it accelerates and responds to the throttle. This helps ensure the distributor points are working right and the car runs well.
