First introduced in the early 1980s with the Komatsu 6D105 engine, the PC200 established Komatsu as a global excavator leader and the nameplate has continued through eight generations to the present day. PC200-1 and PC200-2 machines are now in the classic equipment and long-service veteran category, maintained by operators in markets where machine longevity and rebuild economics are prioritised\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKomatsu 6D105 — The First-Generation Komatsu Heavy Excavator Diesel Engine That Powered the Original PC200:\u003c\/strong\u003e The Komatsu 6D105 is Komatsu’s first-generation 6-cylinder in-line diesel engine for the PC200 excavator and WA300 wheel loader — a robust and well-regarded engine that established Komatsu’s reputation for diesel engine reliability and longevity. Though now a legacy engine, the 6D105 remains in service in numerous markets across Southeast Asia, South Asia, Africa, and Latin America, where the original PC200-1 and PC200-2 machines continue to operate, driving ongoing demand for quality OEM replacement cooling system components\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWater Pump Failure on a Komatsu 6D105 — A Critical Cooling System Event That Can Lead to Engine Overheating and Serious Damage:\u003c\/strong\u003e The water pump is the primary driver of coolant circulation in the Komatsu 6D105 engine cooling system. A failing or failed water pump causes loss of coolant flow — leading rapidly to engine overheating, cylinder head warping, head gasket failure, and potentially severe internal engine damage if operation continues. Water pump replacement at the first sign of coolant leakage, bearing noise, or overheating is a critical preventive maintenance action for 6D105-powered machines, particularly in hot climates where cooling system stress is highest\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eKomatsu WA300-1 — Komatsu’s First-Generation WA300 Wheel Loader in Active Long-Term Service Across Emerging Markets:\u003c\/strong\u003e The Komatsu WA300-1 is the first generation of Komatsu’s WA300 wheel loader series — powered by the Komatsu 6D105 engine. Like the PC200-1 and PC200-2, WA300-1 machines remain in operation across a wide range of markets where extended machine service life is standard practice, maintaining demand for quality OEM replacement cooling system components for the 6D105 engine platform\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003e📦 What's Included\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e1× Water Pump — New Aftermarket (Komatsu 6136-61-1101 \/ 6136-61-1102)\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003e🔑 Key Specs\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eKomatsu OEM Part Numbers:\u003c\/strong\u003e 6136-61-1101, 6136-61-1102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Engine:\u003c\/strong\u003e Komatsu 6D105 — 6-cylinder in-line diesel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Equipment:\u003c\/strong\u003e Komatsu PC200-1 \/ PC200-2 hydraulic excavators — Komatsu WA300-1 wheel loader\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication:\u003c\/strong\u003e Engine cooling system — hydraulic excavator \/ wheel loader — legacy \/ long-service machine maintenance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New Aftermarket\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSKU:\u003c\/strong\u003e 6136-61-1101\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cem\u003e⚠️ Please verify your Komatsu machine serial number and engine serial number against the Komatsu parts book before purchasing.
