SAWAFUJI 24V 35A Alternator for HINO EK100 – Compatible with 270501110B, 1PK

This 24V 35A 1PK alternator is a precision-engineered replacement for the HINO EK100 heavy-duty truck (1984–1995) powered by the 13.3L HX14 diesel engine. Designed for legacy fleet maintenance and restoration projects, it delivers stable charging performance for essential systems—including ignition, lighting, instrumentation, and hydraulic power steering—while maintaining compatibility with the vehicle’s original 24V electrical architecture.

The unit features a standard 1PK (single-rib poly-V) pulley, matching the factory belt configuration for direct bolt-on installation without modification. It eliminates the need for sourcing obsolete or reconditioned OEM units—providing a modern, reliable alternative with improved component longevity.

Fully compatible with a wide range of OEM and aftermarket references, including:
HINO 270501110B / 270501112A,
and legacy cross-references such as ALW5112 / ALW4112LP / ALW4112UX / ALW5112AW / ALW5112UX / ALW7112UX / 301N22314Z.

Manufactured by SANYOU using 100% new, high-grade materials—such as vacuum-pressure-impregnated stator coils, thermally stable rectifier diodes, and a robust IC voltage regulator with over-voltage and reverse-polarity protection—this alternator is built to meet or exceed HINO’s original factory specifications for output, regulation, and service life.

Each unit undergoes rigorous testing, including:

No-load voltage verification (27.0–28.5V @ 2,000 RPM)
Full-load output (≥35A @ 1,800 RPM)
Insulation resistance (>100 MΩ)
24-hour endurance run under simulated load
Ideal for independent truck shops, vintage fleet operators, and export markets where dependable, cost-effective support for aging but still-operational HINO EK100 platforms is essential.
