Product Description
Product Introduction C2874073 Belt Tensioner is a spring-driven automatic tensioning component designed for the ISZ13 engine accessory drive system. It delivers continuous, adjustable preload to the multi-ribbed PK belt, offsetting belt stretch and dynamic torque fluctuation while the alternator, air compressor and cooling fan operate. This aftermarket replacement tensioner eliminates periodic squealing, unstable accessory power supply and premature belt tearing caused by spring fatigue, internal damping loss and worn pulley bearing of old assemblies. Consistent tension stabilizes power transmission and reduces emergency road failure risk for heavy trucks engaged in long-distance bulk cargo transportation.
Product Advantages High-performance torsion spring maintains stable tension output over thousands of working hours. Integrated damping structure absorbs torque oscillation and suppresses tension fluctuation. Hardened pulley and high-quality bearing provide smooth rotation and strong abrasion resistance. Every tensioner undergoes free rotation and tension travel inspection before delivery, OEM mounting position supports quick bolt-on installation without modification.

FAQ
Q1: What difference exists between a bad tensioner bearing and a worn belt?
A1: A rough bearing generates constant rumble, while a worn belt mostly squeals under sudden load.
Q2: What will happen if the tensioner arm travel has reached its limit?
A2: It cannot provide enough tension, slippage occurs even after installing a brand-new belt.
Q3: What maintenance step helps extend the service life of this tensioner?
A3: Keep pulley grooves clean and prevent oil, dust and debris from sticking to the contact surface.
