🔧 Product Highlights

• Direct OEM Replacement — Yanmar 119802-42000 / 119802-42001 Water Pump for Yanmar 3TNV82 / 3TNE82 / 3TN75 / 3TNC78 Small 3-Cylinder Diesel Engine in Yanmar B-Series, VIO-Series Excavators, and C30R Tracked Carrier: Drop-in fit for all compatible Yanmar B22 / B25V / B27 / B30V micro and mini excavators, Yanmar VIO30 / VIO35 zero tail-swing excavators, and Yanmar C30R tracked carrier — matching original Yanmar 119802-42000 water pump specifications for the Yanmar 3TNV82 / 3TN75 / 3TNC78 small diesel engine cooling system
• 8 OEM Part Numbers in Four Yanmar Catalog Formats — Full Coverage for All Yanmar 3TNV82 / 3TN75 Water Pump Identification Systems Including YM-Prefix European Format: Cross-references 8 part numbers across Yanmar standard hyphenated (119802-42000 / 119802-42001), Yanmar continuous (11980242000 / 11980242001), Yanmar YM-prefix hyphenated (YM119802-42000 / YM119802-42001), and Yanmar YM-prefix continuous (YM11980242000 / YM11980242001) — covering all Yanmar dealer (including European YM-prefix format), distributor, and aftermarket catalog formats. The two Yanmar OEM numbers (119802-42000 and 119802-42001) reflect a running design update for the same water pump application across the 3TNV82 / 3TNE82 production transition
• Yanmar VIO30 and VIO35 — Yanmar’s Zero Tail-Swing Mini Excavators and One of the Most Popular Confined-Space Excavators in Urban Construction and Landscaping: The Yanmar VIO30 and VIO35 are Yanmar’s zero tail-swing mini excavators — designed for confined urban construction sites, courtyard and garden access, utility trenching in tight residential streets, and indoor demolition where a standard tail-swing excavator cannot safely rotate without risk of collision. The VIO series is one of Yanmar’s most recognisable and widely sold product lines in Japan, Europe, and Australia, where urban construction density and tight-site access requirements make zero tail-swing capability a critical procurement requirement
• Yanmar 3TNV82 — Yanmar’s Tier 4 Final Certified 3-Cylinder Diesel and the Current Standard Engine Across Yanmar’s B-Series and VIO-Series Mini Excavator Platform: The Yanmar 3TNV82A is Yanmar’s current Tier 4 Final certified 3-cylinder diesel engine — the standard power unit across Yanmar’s B25V, B30V, VIO30, and VIO35 mini excavators and the C30R tracked carrier. The 3TNV82 shares water pump part number commonality with the earlier 3TNE82 (Tier 2) generation, simplifying parts identification across the generation transition and supporting mixed fleets with both Tier 2 and Tier 4 machines
• Yanmar B22 / B27 — Yanmar’s Sub-3-Tonne Micro Excavators for Maximum Compact Access in the Tightest Residential and Urban Sites: The Yanmar B22 and B27 are Yanmar’s smallest excavator models — sub-3-tonne micro excavators designed for the most confined access applications: narrow gate access for residential landscaping, swimming pool excavation, basement and underpinning work in tight urban plots, and indoor demolition. These machines are popular with owner-operator landscapers and specialist urban construction contractors who need maximum productivity from the smallest possible excavator footprint
• Yanmar C30R — Yanmar’s 3-Tonne Tracked Carrier for Site Material Transport on Slopes and Confined Ground Conditions Where Wheeled Vehicles Cannot Access: The Yanmar C30R is a 3-tonne tracked carrier / site dumper — used alongside mini excavators on landscaping, groundworks, and civil engineering projects to transport excavated material, aggregate, concrete, and topsoil across terrain that wheeled dumpers cannot access, including steep slopes, soft ground, and confined garden or urban sites. The C30R shares the same Yanmar 3TNV82 engine and water pump as the VIO30 / VIO35 excavators, allowing consolidated parts stocking for Yanmar-powered mini excavator and tracked carrier fleets

⚠️ Please verify your Yanmar machine model and engine designation (3TNV82 / 3TNE82 / 3TN75 / 3TNC78) before purchasing. The 119802-42000 and 119802-42001 are successive OEM part numbers for the same water pump application. Contact us if unsure — we are happy to confirm fitment for your Yanmar B-series, VIO-series, or C30R.
