This 24V 50A alternator is engineered for modern construction and utility machines where the charging system must coexist with high-load hydraulic and pneumatic drives. The 12-groove design ensures maximum belt-to-pulley contact area—critical for maintaining tension during sudden load spikes, such as boom extension or attachment engagement on JCB JS220, JS260, and Kobelco SK140-8 excavators.
It fits Isuzu 4HK1-TC/T engines (common in carrier chassis), Komatsu PC300-7 (6D114), and replaces OEM units, including:
Isuzu 8973750171, 8980921161,
JCB 71440523,
Mitsubishi 3266800101, and
Nikko 0350004598 / 0350004848.
Manufactured by SANYOU, the 80mm pulley diameter matches original equipment tolerances to preserve accessory drive alignment—preventing premature belt wear or harmonic vibration in tightly integrated engine compartments.
