🔧 Product Highlights

• Direct OEM Replacement — Isuzu / Hitachi 1811003381 / Denso 0240003150 24V 11T Starter for Isuzu 6BD1 / 6BG1 / 6BG1T Engine in Hitachi ZX200–ZX300 Series Hydraulic Excavators: Drop-in fit for all compatible Hitachi ZX-series excavators from ZX125W through ZX300W — matching original Isuzu / Hitachi 1811003381 24V 11T starter specifications for the Isuzu 6BD1 / 6BG1 / 6BG1T diesel engine platform powering Hitachi’s core 20–30-tonne excavator range
• 6 OEM Part Numbers Across Isuzu / Hitachi and Denso — Full ZX200–ZX300 Generation and Variant Coverage: Cross-references 6 part numbers across Isuzu / Hitachi OEM (1811003381 / 1811003380 / 1811003420 / 1811003421) and Denso OEM (0240003150 / 0240003151) — the four Hitachi OEM numbers cover successive production updates and running changes to the starter specification across ZX-series generation 3G, 5G, HHE, AMS, and HCME production variants, while the two Denso numbers are the OEM manufacturer’s references confirming the Denso-sourced starter design
• Hitachi ZX200 and ZX210 — Hitachi’s Best-Selling and Most Widely Deployed 20-Tonne Excavators and the Global Standard for Medium Hydraulic Excavator Performance: The Hitachi ZX200 and ZX210 series are Hitachi Construction Machinery’s flagship 20-tonne excavators — consistently among the best-selling hydraulic excavators in Hitachi’s global lineup across multiple generations (3G, 5G, HHE, AMS, HCME). The ZX200 and ZX210 are the reference machines for medium excavator performance in civil engineering, road construction, building foundation work, and utility earthworks in North America, Europe, Japan, Australia, and Southeast Asia. The large global installed base of Hitachi ZX200 and ZX210 excavators in active service drives sustained, high-volume aftermarket demand for Isuzu 6BG1 engine components including starters
• Isuzu 6BG1 / 6BG1T — Hitachi’s Long-Running OEM Engine Partnership and One of the Most Widely Serviced Diesel Engines in the Global Construction Equipment Aftermarket: The Isuzu 6BG1 and its turbocharged (6BG1T) and turbocharged-intercooled (6BG1TC) variants have been Hitachi Construction Machinery’s OEM engine of choice for the ZX-series medium excavator platform across multiple generations. The Isuzu-Hitachi engine partnership is one of the most enduring OEM relationships in the construction equipment industry, producing one of the largest installed bases of a single engine type in the global medium excavator segment. The 6BG1 engine’s longevity across Hitachi’s ZX platform ensures sustained aftermarket demand for starters and other engine components
• Hitachi ZX225US / ZX225USR — Hitachi’s Ultra-Short and Ultra-Short Radius Excavators for Urban and Confined-Site Construction: The Hitachi ZX225US and ZX225USR are Hitachi’s ultra-short-radius (US) and ultra-short-radius rotating (USR) excavator models — designed for confined urban construction sites, city centre building projects, and locations where a standard tail-swing excavator cannot operate safely. The ZX225US series is particularly popular in Japan, Europe, and Australia where urban construction density requires compact tail-swing performance at 20-tonne class productivity
• Hitachi Construction Machinery — Japan’s #1 Excavator Brand and One of the Top 3 Global Construction Equipment Manufacturers: Hitachi Construction Machinery (HCM, a Hitachi, Ltd. and KKR company) is Japan’s largest excavator manufacturer and one of the three largest construction equipment companies globally alongside Caterpillar and Komatsu. Hitachi excavators are the market leader in Japan and hold leading positions in Southeast Asia, Australia, and other key markets. The Hitachi ZX-series excavator platform is one of the most widely sold hydraulic excavator product lines in the world, driving a large and sustained global aftermarket for Isuzu engine components
