This is a brand-new OEM driven pulley kit with part number GT79244, exclusively engineered for RT400 CVT transmissions and a direct replacement for the original part number MIA12482. As a core power transmission component of the CVT transmission system for lawn tractors, the kit is a complete assembly of driven pulley parts that undertakes the critical function of receiving and transmitting the rotational power from the drive pulley to the transmission's internal drive structure, ensuring the smooth and stepless speed change of the lawn tractor and the stable output of driving power. It is an essential maintenance and replacement accessory for solving faults such as pulley slipping, abnormal speed change, power loss, noise or structural looseness caused by wear, deformation, bearing damage or rubber part aging of the original driven pulley, and restoring the complete power transmission and speed change performance of the RT400 CVT transmission system.

The GT79244 driven pulley kit is crafted with high-quality high-strength metal materials and durable elastic rubber components, featuring excellent structural firmness, wear resistance, impact resistance and elastic performance. Each part in the kit is processed by precision machining technology with strict dimensional tolerance control, and the perfect matching between the pulley, bearing, spring and other components meets the original factory standard of the RT400 CVT transmission. Its precise structural design perfectly matches the installation position of the RT400 CVT transmission, with a tight and stable connection with the transmission body and drive components, no slipping or loosening during high-speed rotation and power transmission, and can withstand the long-term working load of the lawn tractor's transmission system, ensuring the smooth and reliable stepless speed change and power transmission.

This genuine OEM GT79244 driven pulley kit is the ideal original replacement for the worn, deformed, damaged or poorly performing original driven pulley assemblies of RT400 CVT transmissions on lawn tractors. The kit is a complete original assembly designed in accordance with factory standards, with all parts pre-matched and pre-assembled to ensure the best working performance of the driven pulley. It perfectly matches the original RT400 CVT transmission structure, realizing seamless installation with no additional adjustment, modification or part matching required, and the replacement operation is simple and quick. Installing this component restores the stable and efficient power transmission and stepless speed change performance of the RT400 CVT transmission, ensures the smooth and flexible operation of the lawn tractor during mowing and walking, and is a necessary maintenance part for the daily use, fault repair and overhaul of lawn tractors equipped with the RT400 CVT transmission system.
