Yanmar 729402-14580 Camshaft Assembly

The Yanmar 729402-14580 camshaft is a critical valve train component engineered for Yanmar 4-cylinder TNV and TNE series diesel engines. It features a slot drive configuration for gear engagement and is manufactured to OEM specifications for heat-treated durability and dimensional accuracy. This camshaft regulates intake and exhaust valve timing, directly influencing engine breathing efficiency, emissions compliance, and power output. It serves as a direct replacement for Yanmar OEM part numbers 729402-14580, Y729402-14580, and YM729402-14580. Compatible engine platforms include Yanmar 4TNE84, 4TNE88, 4TNV84, 4TNV84T, and 4TNV88 series. Typical equipment applications encompass mini excavators, skid steer loaders, and compact tractors from manufacturers such as Komatsu, Case, Hyundai, Hitachi, Gehl, and Yanmar industrial power units. The component is constructed from high-grade alloy steel with induction-hardened lobes and journals to withstand high-contact stresses and prolonged duty cycles in heavy-duty off-highway environments.
