The distributor in the 1986 Toyota pickup truck works by distributing the electrical spark from the ignition coil to the spark plugs in the engine. The distributor is located on the front of the engine and is driven by the camshaft. The distributor consists of a rotating arm, called a rotor, and a set of stationary contacts, called points.
The rotor is connected to the ignition coil and the points are connected to the spark plugs. As the camshaft rotates, it causes the points to open and close. When the points open, the electrical current from the ignition coil flows through the rotor to the spark plug wires, which carry the current to the spark plugs. The spark plugs then ignite the fuel mixture in the cylinders, causing the engine to run.
The distributor also contains a mechanical advance mechanism. The mechanical advance mechanism adjusts the timing of the spark so that the spark plugs fire at the correct time in relation to the movement of the pistons in the engine.
Electronic Ignition System
The 1986 Toyota pickup truck may also be equipped with an electronic ignition system. An electronic ignition system uses an electronic control module to control the ignition timing instead of a mechanical advance mechanism. The electronic control module receives signals from sensors in the engine and uses these signals to adjust the timing of the spark.
Electronic ignition systems are more accurate and reliable than mechanical advance mechanisms. They also provide better performance and fuel economy.
How to Replace the Distributor
Replacing the distributor in a 1986 Toyota pickup truck is a relatively straightforward task. However, it is important to follow the instructions carefully to avoid damaging the engine.
Here are the steps involved in replacing the distributor:
1. Disconnect the negative battery cable.
2. Remove the distributor cap.
3. Remove the rotor.
4. Remove the hold-down clamp.
5. Pull the distributor out of the engine block.
6. Inspect the distributor gear and the camshaft gear for damage.
7. If necessary, replace the distributor gear or the camshaft gear.
8. Lubricate the distributor shaft and the distributor gear with a high-temperature grease.
9. Insert the distributor into the engine block and secure it with the hold-down clamp.
10. Install the rotor.
11. Install the distributor cap.
12. Connect the negative battery cable.
