The John Deere crankshaft rear oil seal TRE44574 is a high-precision sealing component designed specifically for John Deere engines, playing a crucial role in the engine lubrication system. This product is installed at the rear end of the engine crankshaft, with the main function of preventing oil leakage from the crankcase and blocking external pollutants from entering the engine interior, ensuring a clean and efficient operating environment for the engine.
Core features of the product
High quality material formula: It adopts special synthetic rubber materials and has excellent heat resistance, oil resistance and anti-aging properties through precise formula design. It can maintain elasticity within the temperature range of -40 ℃ to 200 ℃ and adapt to the thermal expansion and contraction of the engine under various working conditions.
Precision structural design: The unique lip design ensures a perfect fit with the crankshaft surface, providing uniform contact pressure. Internally reinforced skeleton provides stable support, prevents seal deformation, and ensures sealing reliability during long-term use.
Surface treatment process: The sealing lip adopts special surface treatment technology to reduce friction coefficient, minimize crankshaft wear, and improve sealing effect. The static part adopts anti rotation design to ensure that there will be no displacement after installation.
Long term service life: After rigorous bench testing, it can maintain long-term stable sealing performance under high-speed rotating conditions, with a service life of over 5000 hours, significantly reducing maintenance frequency.
Applicable models and installation instructions
This product is suitable for various diesel engines such as John Deere 6.8-liter and 8.1-liter, and is widely used in John Deere tractors, combine harvesters, construction machinery, and other equipment.
