Product Description

IDLER/TENSIONER PULLEY, HD, DAYCO

Features & Benefits

  • Rounded 74 mm pulley edge offers a stable belt contact zone
  • Generous 39.25 mm width accommodates serpentine drive layouts
  • High-strength steel core forms a rigid pulley structure
  • Smooth contact disc allows a consistent belt seating surface
  • Multi groove 08 rib layout fits structured routing paths
  • Balanced hub opening supports aligned pulley mounting

Dayco Drive Belt Tensioner Pulley

When serpentine belt alignment must remain controlled under fluctuating engine demand, the Dayco Drive Belt Tensioner Pulley guides belt tracking across accessory drive systems. Changes in engine speed and load shift belt tension, and the pulley manages that movement to reduce slack and misalignment. Continuous tension control supports engagement between the belt and driven components such as alternators and compressors. The flat pulley surface allows the multi-rib belt to maintain proper contact without lateral deviation. The Dayco 89101 supports consistent belt tracking across accessory loads through its structured tension-management profile.
