About Us
FAQ
Q: 1. What type of component is the Cummins alternator 3400698?
A: The 3400698 is a genuine Cummins 24V brushless alternator, specifically designed to complement heavy-duty diesel engines such as the KTA19, QSK19, NTA855, and M11. Its function is to charge the vehicle's battery and supply power to electronic systems-such as the ECU and various sensors-and it is *not* an injector.
Q: 2. How reliable is this alternator in high-humidity environments?
A: Featuring a corrosion-resistant aluminum alloy housing and a specialized surface treatment, this alternator is engineered to withstand high-humidity and rainy operating conditions-such as those found in Chongqing. It effectively resists corrosion from salt spray and oil contamination; field testing has demonstrated an average trouble-free operating life exceeding 15,000 hours, with a maintenance interval of up to 2,000 hours.
Q: 3. Why is it essential to use the genuine Cummins 3400698 alternator rather than a substitute?
A: The genuine Cummins 3400698 alternator is deeply integrated with the engine ECU's voltage regulation logic, ensuring that output voltage fluctuations remain within ±1% and Total Harmonic Distortion (THD) stays below 3%. This precise compatibility prevents issues commonly associated with non-genuine parts-such as insufficient charging, erroneous ECU fault codes, or electronic system failures.
Q: 4.What are the packaging requirements for the international shipment of the 3400698 alternator?
A: The packaging requires a multi-layer structure consisting of an inner anti-static film, a middle layer of foam cushioning, and an outer container-either an ISPM-15 compliant wooden crate or a high-strength corrugated cardboard box. The package must be clearly labeled as containing "Precision Electrical Components," and it is strictly prohibited to ship it alongside liquids or chemicals, thereby ensuring protection against shock and moisture during transit.
