• 4 Komatsu OEM Part Numbers — Covering PC300-5 / PC300-6 Generation and All PC350 / PC340 / PC380 Variants: Cross-references 4 Komatsu OEM starter part numbers (600-813-6410 / 600-813-6510 / 600-813-6411 / 600-813-6412) covering the full SA6D108 / SAA6D108E-2A engine generation across Komatsu’s PC300-5, PC300-6, PC310-5, PC340-6K, PC350-6, and PC380-6K series excavators
• 7.5kW — High-Output 24V Starter for the Komatsu SA6D108 / SAA6D108E-2A Large-Displacement 6-Cylinder Diesel: At 7.5kW on a 24V system, this starter delivers the maximum cranking torque required for reliable cold-weather starting and high-duty-cycle engine cranking on the Komatsu SA6D108 / SAA6D108E-2A — a large-displacement 6-cylinder diesel engine used across Komatsu’s 30–38-tonne excavator range. The 12T 46mm drive gear confirms heavy-duty flywheel engagement specification for sustained large excavator duty cycles
• Komatsu PC300 / PC350 — Komatsu’s Most Widely Deployed 30–35-Tonne Large Hydraulic Excavator Platform Globally: The Komatsu PC300 and PC350 series are Komatsu’s flagship large-class hydraulic excavators in the 30–35-tonne weight class — among the most widely sold and actively deployed large excavators globally. PC300 and PC350-series machines are deployed in major civil engineering, road and highway construction, dam and reservoir works, mining and quarry operations, and large-scale land development projects across every continent. Komatsu is one of the two largest construction equipment manufacturers in the world (alongside Caterpillar), ensuring a massive and sustained global installed base for PC300 / PC350 series excavators
• SA6D108 / SAA6D108E-2A — Komatsu’s Proven Large-Displacement In-Line 6-Cylinder Diesel Engine Across the PC300 / PC350 Generation: The Komatsu SA6D108 (PC300-5 / PC310-5 generation) and SAA6D108E-2A (PC300-6 / PC350-6 generation) are Komatsu’s in-house large-displacement 6-cylinder diesel engines — built to Komatsu’s own design for exceptional durability, fuel efficiency, and long service life in demanding large-excavator duty cycles. These engines are well-regarded in the construction industry for their reliability and ease of field service
• Starter Failure on a Komatsu PC300 / PC350 — Critical Downtime on Major Civil Engineering and Mining Project Sites: A failed starter on a Komatsu PC300 or PC350 large excavator causes immediate high-cost machine downtime on major project sites — directly impacting earthworks production rates, project schedules, and contract milestone obligations. At the 30–35-tonne excavator class, machine downtime costs are substantial, making rapid starter replacement a priority maintenance action for site managers and fleet operators
