Premium Engine Overhaul Rebuild Kits for Yanmar 4TNV98 Series

Restore your equipment’s power and efficiency with a comprehensive overhaul rebuild kit designed for Yanmar 4TNV98 and 4TNV98T engines. These 3.3L, 4-cylinder engines are the backbone of high-performance machinery like the Yanmar ViO80-1, ViO82, and T80N 4WD tractors. A full rebuild ensures consistent compression and thermal stability, which is vital for heavy-duty excavation and agricultural tasks.

Most kits feature precision-engineered pistons and a full gasket set (including a multi-layer steel head gasket) to provide a superior seal under high-pressure conditions. Whether your engine is naturally aspirated or turbocharged, these kits provide all the internal rotating components—such as main bearings, rod bearings, and thrust washers—needed to bring the engine back to factory specifications.
