24V 110A Prestolite Alternator – Fits Cat 3176, Cummins, Detroit Diesel, Volvo – 110-459, 8392N

Keep aging Caterpillar 3176–equipped agricultural, construction, and industrial equipment running reliably—where original 110A alternators commonly fail due to rectifier diode fatigue, regulator drift, or bearing seizure after years of high-vibration service. This heavy-duty unit delivers a stable 24V output for engine control systems, fuel injection pumps, hydraulic valve solenoids, and safety interlocks, even under low-RPM or fluctuating load conditions.

It cross-references major OEM numbers:
Caterpillar: 27175
Cummins: TM5594-001
Detroit Diesel: 23529038
International Navistar: 3812990C91, ZLN110459
Volvo / Volvo Penta: 9012724607, LN 110459
Mack: 5034-110459
John Deere: TM5594001
Lucas: LRA02419
Motorola: 8LHA3096U, 8LHA3096UAH, 8LHA3096UC
Prestolite: 110-459
WAI: 8392N
LESTER: 8392

Features a standard two-terminal (B plus and D plus) external regulator configuration and mounts directly to the original bracket—no wiring changes or adapter plates required.

Manufactured by SANYOU, every alternator uses 100 percent new copper windings, heavy-duty rectifier assemblies, double-sealed ball bearings, and a thermally compensated voltage regulator rated for continuous operation in high-heat, high-vibration environments. Full-load bench testing confirms output stability, ripple voltage, and thermal performance meet or exceed original equipment specifications.

Backed by SANYOU’s commitment to quality in the global industrial aftermarket, this alternator is widely specified by fleet maintenance teams and equipment rebuilders for dependable, drop-in replacement across legacy and current-duty platforms.
