This 24V 40A 3PK82 alternator is engineered as a versatile replacement for a range of industrial and heavy-duty applications, including Nissan CW40, CW41, and CW50 trucks, as well as Hitachi hydraulic cranes and mobile equipment, all powered by PD6, PD6T, or PE6 series diesel engines. With a robust 40-amp output, it ensures stable power delivery for critical functions—such as hydraulic pump solenoids, boom control systems, work lighting, safety interlocks, and onboard diagnostics—even in high-vibration, high-temperature operating environments.
The unit features a precision-machined 3PK pulley (82mm diameter) designed to match the original equipment’s belt routing and tension requirements, minimizing slippage and extending serpentine belt service life. Its compact footprint and standardized mounting geometry allow for direct replacement without adapter brackets or wiring modifications.
It is fully compatible with multiple OEM and legacy part numbers, including:
HINO 2310097105 / 2310096015 / 2310091019,
LT22522C / LT21520, and aftermarket equivalents such as A2310097105.
Manufactured by SANYOU under strict quality protocols, this alternator is built with 100% new components: high-purity copper windings, thermally enhanced rectifier modules, dual-shielded bearings rated for 8,000+ hours, and a microprocessor-based voltage regulator with soft-start and load-dump suppression. Each unit undergoes comprehensive validation, including:
Output stability under variable loads (30–42A range)
Ripple voltage <180mV
Thermal endurance (85°C ambient, 500-hour continuous run)
Dielectric strength test (≥500V AC)
