( Manufacturer Part Number: 1112494 ), ( Part Type: Distributor )
The 1973-1978 GM Distributor 1112494 is a vital component of the ignition system in various General Motors and GMC vehicles from the mentioned years. This distributor is a testament to the engineering prowess of the era, designed to deliver reliable and efficient spark distribution to the engine's cylinders.
The distributor housing is constructed from a robust material, likely cast iron or aluminum, ensuring durability and resistance to heat. It houses the rotor, which is an essential part of the distributor. The rotor, in this case, is a multi-lobe design, allowing it to make multiple electrical connections as it spins. Each lobe corresponds to a specific cylinder, ensuring the spark is delivered at the right moment for optimal combustion.
The distributor cap, which sits atop the housing, is also a crucial part of this component. It protects the rotor and the spark plug wires from the elements and allows the high-voltage spark to pass through to the spark plugs. The 1973-1978 GM Distributor 1112494 features a robust, weather-resistant cap with multiple ventilation slots to escape excess heat.
The distributor is operated by the engine's camshaft, which drives the distributor gear. The gear, in turn, spins the rotor. The timing of this rotation is critical for proper engine operation, and the distributor is equipped with a timing mark to ensure correct setup.
This 1973-1978 GM Distributor 1112494 is a valuable replacement part for vehicles that require a distributor-based ignition system. It is a direct fit for specific GM and GMC models, ensuring a straightforward installation process. With its durable construction and reliable performance, this distributor is an excellent choice for restoring or maintaining the ignition system of your classic vehicle.
