Prosedur pemasangan distributor secara rinci pada sistem pengapian konvensional

Summary

This video script demonstrates the process of installing a distributor on an engine trainer or vehicle. It covers essential steps, including ensuring correct ignition timing, positioning the distributor properly, and ensuring all components are aligned and connected. The process involves careful checks such as verifying timing marks and ensuring no interference when the engine is started. The procedure is explained in detail, from securing the distributor to adjusting the ignition system for proper engine performance, making sure the system operates smoothly and safely.

Takeaways

• 😀 Ensure proper ignition timing before installing the distributor on the engine or vehicle.
• 😀 Position the ignition timing at 8 degrees before top dead center (TDC) for this engine model.
• 😀 Always rotate the crankshaft in the correct direction (clockwise) to set the timing.
• 😀 Make sure that cylinder 1 is in compression stroke before setting ignition timing.
• 😀 Use your finger to feel when the intake valve opens and closes during the compression stroke.
• 😀 Verify the timing marks and ensure they align with 8 degrees before TDC for accurate ignition setup.
• 😀 Check that the distributor is properly aligned with the engine mount and securely fastened.
• 😀 Make sure the vacuum advance on the distributor is properly connected to the intake manifold.
• 😀 Install the distributor cap correctly, ensuring the rotor is pointing towards cylinder 1.
• 😀 Tighten the distributor mounting bolts securely, but allow some movement for fine-tuning ignition timing.
• 😀 After installation, use a high-voltage test cable to check for a spark at the ignition coil and adjust the timing if necessary.

Q & A

What is the first step in the process described in the video?

The first step is dismantling and inspecting the distributor units before proceeding to install them on the engine or vehicle trainer.

How is the ignition timing set before installing the distributor?

The ignition timing is set to 8 degrees before top dead center (TDC), which is confirmed using the appropriate key to rotate the engine in a clockwise direction.

What is the significance of adjusting the ignition timing on cylinder 1?

Adjusting the ignition timing on cylinder 1 ensures that the engine's spark occurs at the correct moment in the compression cycle, which is crucial for proper engine operation.

How do you ensure the distributor is aligned properly before installation?

The distributor must be aligned with the marking on the engine to ensure proper seating. This alignment ensures the distributor is positioned correctly and functions as intended.

Why is it important to check the intake valve position during the ignition timing process?

Checking the intake valve position ensures that the engine is at the correct stage of the compression cycle before setting the ignition timing, ensuring the spark occurs at the right time.

What does the technician need to do before installing the distributor?

Before installation, the technician checks that the distributor is aligned, the ignition timing is correctly set, and the rotor points toward cylinder 1.

How do you confirm that the distributor is installed correctly?

The distributor is installed correctly when it is aligned with the engine's markings, and the rotor points toward the correct cylinder, with the high-tension chord connected to the proper terminals.

What should be done to ensure the distributor is securely fixed after installation?

After installing the distributor, the technician should tighten the distributor mounting bolts, ensuring it is secure but can still be rotated for fine-tuning the ignition timing.

How is the ignition timing adjusted once the distributor is installed?

The ignition timing is adjusted by rotating the distributor until a spark jump occurs, confirmed by observing the high-tension cable, after which the distributor is tightened in place.

What is the final step before starting the engine?

Before starting the engine, the technician ensures that all connections, including the ignition system and distributor, are securely connected, and no components are obstructing engine startup.
