Product Description
Product Introduction C5662690 Belt Tensioner is an automatic tensioning device designed for ISZ14 engine auxiliary drive system. It maintains steady pressure on the multi-ribbed PK belt, offsetting belt stretch and torque fluctuations when alternator, air compressor and cooling fan work alternately. This aftermarket replacement tensioner resolves slipping squeal under heavy load, unstable charging performance and accelerated belt cracking caused by torsion spring fatigue, damping failure and seized internal bearing of old units. Consistent tension reduces slip heat accumulation and ensures reliable operation of cooling and charging systems for heavy-duty long-haul freight trucks.
Product Advantages High-strength torsion spring keeps stable elastic force under long-time vibration and temperature change. Built-in rubber damping structure absorbs torque surges and suppresses vibration. Hardened idler pulley paired with high-quality bearing achieves smooth rotation and abrasion resistance. Every tensioner undergoes torsion force test and free rotation inspection before delivery, OEM mounting contour for convenient bolt-on installation.

FAQ
Q1: What will happen if the tensioner damping function loses effectiveness?
A1: Belt tension bounces up and down repeatedly, generating squealing and accelerating belt fatigue.
Q2: How can you tell if the pulley bearing inside the tensioner is damaged?
A2: You can hear rumbling noise, and the pulley feels rough or has side play when rotated by hand.
Q3: Why should you not over-stress the tensioner arm when servicing the belt?
A3: Excessive bending beyond its travel range can permanently deform the internal torsion spring.
