Product Description
Product Introduction C2874071 Belt Tensioner is the spring-loaded automatic tensioning assembly built for ISZ13 engine auxiliary drive layout. It applies constant preload force on the PK belt, compensating for belt elongation and runtime wear to prevent slippage during load changes. This aftermarket replacement tensioner resolves rhythmic squealing noise, intermittent charging or air compressor failure and accelerated belt wear caused by internal spring fatigue, damping decay and idler bearing roughness of old tensioners. Stable tension control protects alternator, air compressor and cooling fan functions, lowering the risk of auxiliary system breakdown on long-haul highway trucks.
Product Advantages High-strength torsion spring maintains steady tension output across the full travel range. Built-in rubber damper suppresses vibration oscillation when load spikes occur. Hardened idler pulley surface reduces friction and abrasion against belt ribs. Every tensioner is inspected for spring travel, damping performance and bearing smoothness before shipment, OEM mounting hole layout supports direct bolt-on installation.

FAQ
Q1: What sign tells that the tensioner has reached its service limit?
A1: The tensioner arm hits its end stop, and the belt still cannot maintain enough friction.
Q2: How does a failed tensioner damper affect the PK belt?
A2: Tension fluctuates repeatedly, creating cyclic slip noise and speeding up belt fatigue cracking.
Q3: What inspection should be done after installing this new tensioner?
A3: Confirm the belt sits fully in all grooves, check pulley alignment and test for abnormal noise.
