Description
Overview:
This non-genuine water pump is a direct replacement for Yanmar 4TNV94 and 4TNV98 diesel engines used in construction and garden machinery. Built around a robust cast metal housing with a precision-machined hub and sealed shaft assembly, it circulates coolant through the engine to maintain stable operating temperature and prevent overheating. It replaces OEM references 129900-42000, 129900-420001 and 129900-42002, offering dependable performance without the cost of a genuine unit. Suitable for equipment such as compact excavators and compactors, including models like the Volvo ECR58 that use these Yanmar engines, it is designed as a straightforward swap for tired or leaking pumps to help restore reliable cooling and protect engine components from heat-related damage.
