( Manufacturer Part Number: D7304-D5704 ), ( Type: Distributor )
The Nissan D7304 D5704 distributor is a crucial component in the ignition system of certain 1986-1988 300zx models equipped with the VG30 or VG30T engine, specifically those with the 22100-21P00 part number. This distributor, manufactured by Hitachi, ensures reliable and efficient spark delivery to each cylinder for proper engine operation.
The distributor housing is designed with a robust construction, made primarily of aluminum, to withstand the rigors of continuous engine operation. The external threads on the distributor shaft are made to securely connect to the crankshaft or camshaft, depending on the specific engine configuration.
The distributor cap sits atop the housing and houses the rotor. The cap has a hexagonal shape and is engineered to accommodate eight spark plug boots, one for each cylinder. The cap's design allows for efficient spark jump gaps between each plug boot, ensuring optimal spark delivery to the engine.
Inside the distributor, a cam rotor is connected to the distributor shaft. The cam rotor, designed with a lobed surface, interacts with the distributor cam inside the housing to rotate the distributor shaft and trigger the spark plugs in the correct order.
The distributor also includes a vacuum advance mechanism, which utilizes engine vacuum to advance the timing of the spark delivery for improved engine performance under light-load conditions. This mechanism is critical for smooth idle and efficient combustion at various engine speeds.
Additionally, the distributor features a centrifugal advance mechanism, which advances the spark timing based on engine RPM to optimize combustion for power and performance.
This Hitachi Nissan D7304 D5704 distributor is a vital component in maintaining the proper ignition system function in your 1986-1988 300zx with the VG30 or VG30T engine and the given part number.
