Title: High-Output 600-825-3160 24V 40A Alternator with 8PK80 Pulley for KOMATSU PC350-7 6D114 Engine Generator
Reliable charging system performance is essential for heavy equipment operation. For the KOMATSU PC350-7 excavator and other machinery powered by the 6D114 engine, the 600-825-3160 alternator (also referenced as 6008253160) delivers 24V and 40A of stable electrical power. Featuring an 8PK80 multi-rib belt pulley, this alternator is designed to keep batteries charged and electronics running in demanding construction, mining, and generator applications.
Engineered for KOMATSU 6D114 Engine Platform
The 6D114 is a 6-cylinder, 11.4-liter diesel engine widely used in KOMATSU hydraulic excavators, bulldozers, and generator sets. The 600-825-3160 alternator is a direct replacement for the original charging unit, providing 24V nominal output with 40 ampere capacity – sufficient for starting systems, lighting, control modules, and auxiliary equipment. The 8PK80 designation indicates an 8-rib serpentine belt pulley with an 80mm diameter (or a specific groove profile), ensuring proper belt alignment and tension.

Why Choose This 24V 40A Alternator?
-
Correct Voltage & Amperage: 24V nominal (28V regulated) and 40A output – ideal for medium-duty construction equipment without overloading the electrical system.
-
8PK80 Serpentine Pulley: The 8-rib, 80mm pulley ensures belt compatibility with factory drive systems, reducing slip and noise.
-
Durable Construction: Sealed bearings, high-temperature insulation, and corrosion-resistant housing withstand dust, vibration, and moisture.
-
Direct Bolt-On: Matches OEM mounting bracket dimensions and connector types (typically B+ terminal, D+ excitation, and ground).
Signs Your Alternator Needs Replacement
-
Dim or flickering lights
-
Low battery voltage warning (below 24V)
-
Battery not charging even after replacement
-
Unusual noise (whining or grinding from alternator)
-
Burnt smell or visible smoke
-
Dead batteries after short operation periods
Installation Tips
-
Disconnect the battery ground cable before removal.
-
Note belt routing – the 8PK80 belt must sit correctly in all pulleys.
-
Torque mounting bolts to manufacturer specifications (typically 25-35 Nm for M8 bolts).
-
Check belt tension – deflection should be 10-15mm under moderate thumb pressure.
-
After installation, measure charging voltage (should be 27.2V – 28.4V at 24V nominal).
Conclusion
The 600-825-3160 (6008253160) 24V 40A alternator with 8PK80 pulley is the perfect charging solution for KOMATSU PC350-7 excavators, 6D114 engines, and compatible generator sets. Restore reliable electrical performance and avoid downtime with this high-quality replacement alternator.
