Compatible with Cummins ISX15 and QSX15 Engines in Construction Equipment – Belt Tensioner (Part No. 3104029)
The belt tensioner with part number 3104029 is a precision-engineered, OEM-specification component specifically designed for seamless integration and optimal performance in Cummins ISX15 and QSX15 heavy-duty diesel engines—widely deployed across a broad spectrum of construction equipment, including excavators, wheel loaders, motor graders, and off-highway articulated dump trucks. This robust, spring-loaded automatic tensioner ensures consistent belt alignment and proper drive belt tension throughout extended operational cycles, minimizing slippage, reducing wear on auxiliary components such as alternators, air compressors, and water pumps, and significantly extending overall belt service life. Built to withstand extreme vibration, thermal cycling, dust ingress, and harsh working environments typical of rugged construction sites, the 3104029 tensioner features high-strength alloy steel construction, corrosion-resistant surface treatment, and calibrated torsional damping characteristics 

Belt tensioner (Part No. 3104029) compatible with Cummins ISX15 and QSX15 engines used in construction equipment.
