🔧 Product Highlights

• Direct OEM Replacement — Komatsu 600-861-6420 / Denso 101211-7960 24V 60A 8-Groove Alternator for Komatsu SAA6D107E / SAA6D102E / SAA4D107E / SAA4D102E / SAA4D95LE Engine Platform: Drop-in fit for all compatible Komatsu PC-series excavators, HB hybrid excavators, PW wheeled excavators, and WA-series wheel loaders — matching original Komatsu / Denso 24V 60A 8-groove belt pulley alternator specifications for reliable onboard electrical generation across the Komatsu Tier 3 / Tier 4 Interim engine platform
• 8 OEM Part Numbers Across Komatsu and Denso — Hyphenated and Continuous Format Coverage for All Komatsu and Denso Parts Catalog Systems: Cross-references 8 part numbers across Komatsu OEM hyphenated (600-861-6420 / 600-861-6410), Komatsu OEM continuous (6008616420 / 6008616410), Denso OEM hyphenated (101211-7960 / 102211-4050), and Denso OEM continuous (1012117960 / 1022114050) formats — covering all Komatsu dealer (SIS / Komatsu Parts), Denso, and aftermarket catalog reference systems
• SAA6D107E — Komatsu’s Most Widely Deployed Tier 3 / Tier 4 Interim 6-Cylinder Diesel Engine Across the PC200–PC308 Excavator and WA200–WA380 Wheel Loader Range: The Komatsu SAA6D107E is Komatsu’s most broadly applied 6-cylinder Tier 3 and Tier 4 Interim diesel engine — used across the full PC200-8 through PC308 excavator generation and the WA200 through WA380 wheel loader range. As the generation 8 Komatsu excavator fleet ages into the high-hour maintenance cycle globally, demand for quality OEM replacement alternators for the SAA6D107E engine platform grows steadily
• PC200-8 / PC220-8 / PC240LC-8 — Komatsu’s Best-Selling Generation 8 Excavators and the Global Standard 20–25-Tonne Hydraulic Excavator: The Komatsu PC200-8, PC220-8, and PC240LC-8 are among the best-selling hydraulic excavators in Komatsu’s history — the global standard for 20 to 25-tonne medium excavators deployed in civil engineering, road construction, building demolition, and utility earthworks worldwide. With hundreds of thousands of generation 8 Komatsu excavators in active service across every continent, the PC200-8 and PC220-8 represent one of the highest-volume aftermarket parts demand platforms in the global construction equipment industry
• HB205 / HB215LC — Komatsu’s Hybrid Excavators with Onboard Electrical Generation Demands That Make Alternator Reliability Critical: The Komatsu HB205-1 and HB215LC-1/2 are Komatsu’s hybrid hydraulic excavators — featuring an electric swing motor and onboard capacitor energy storage system that adds additional electrical load demands on the engine’s alternator beyond standard excavator applications. On hybrid excavators, a reliable alternator output is especially important for sustained hybrid system function
• WA320 / WA380 Wheel Loaders — Komatsu’s Mid-to-Large Wheel Loaders for Quarry, Mining, and Large-Scale Earthmoving Applications: The Komatsu WA320 and WA380 are Komatsu’s mid-to-large class wheel loaders — deployed in quarry face loading, aggregate stockpile management, mining support, port and terminal handling, and large-scale civil earthmoving. At this machine class, electrical system reliability — including the alternator — is a critical uptime factor for fleet operators managing high-production sites where machine downtime directly impacts daily output targets
