Product Overview

Squealing, belt flutter, uneven belt wear or a tensioner arm that no longer holds steady pressure can let the accessory belt slip and shorten belt life. A rough pulley bearing or weak spring can also create noise that is easy to mistake for another front-engine problem.

This replacement tensioner restores controlled belt pressure so driven accessories can stay engaged correctly. It is the appropriate repair when inspection confirms the original tensioner is weak, seized, noisy or no longer tracking the belt properly.

  • Spring-loaded belt tightener for Cat accessory-drive systems
  • One-bolt mounting design

When a manufacturer uses multiple revisions within the same model family, the equipment serial number and original component should be the final fitment check.
