DAYCO 89482 Part Description
Manufacturer
Features & Benefits
- Pulley bearing design reduces rotational drag during accessory startup
- Arm pivot bushing minimizes chatter during rapid throttle transitions
- Coated surfaces guard against early corrosion in damp climates
- Mounting boss spacing simplifies alignment checks during drive-belt service
- Torsion spring design supports long-term belt-tension stability without sagging
Dayco Belt Tensioner
The Dayco Belt Tensioner manages serpentine-belt path control through an automatic spring-loaded arm and a 74 mm pulley that stays aligned with modern accessory-drive layouts. Its construction helps keep belt tracking smooth across fluctuating engine speeds, supporting alternators, pumps, and compressors without abrupt flutter or slack. The pivot mechanism is arranged to withstand repeated directional changes as the belt loads and unloads throughout each drive cycle. The pulley surface provides consistent rotation quality, allowing the belt ribs to move cleanly during long-duration operation. Installation is straightforward thanks to the Dayco 89482’s standard mounting footprint and accessible fastener layout.
