Detailed Description

Hayden Pulley 5086 is an idler pulley for accessory drive belt systems that helps maintain proper serpentine belt routing across the engine accessory drive. Its smooth pulley surface is intended for belt contact where a non-grooved idler is required, and its dimensions are matched for applications that call for a 10 mm bore and 80 mm outside diameter. This part cross-references Gates 36369 for the same application.

Compatible With BMW 128i, BMW 328i, BMW 328i xDrive, BMW 323i, BMW 528i, BMW X3, BMW X5, BMW 525i, BMW 530i, BMW 325i, BMW 330i, and Suzuki Grand Vitara applications listed below. The Hayden 5086 is also a practical search match for drivers replacing a worn BMW 528i idler pulley or BMW 530i serpentine belt pulley.

What This Part Helps Address

  • Belt noise caused by a worn idler pulley bearing
  • Serpentine belt tracking issues from pulley wear
  • Visible pulley surface damage or cracking
  • Accessory drive belt vibration from an out-of-round pulley
  • Maintenance replacement on high-mileage belt drive systems

Installation Notes and Tips

Verify pulley diameter, bore size, belt width, and mounting-hole layout before installation. Mounting hardware is not included, so reuse or source the correct hardware for the vehicle. Inspect the serpentine belt, tensioner, and adjacent pulleys at the same time to confirm the full accessory drive system is in serviceable condition.

Quality Assurance

Hayden 5086 is specified as meeting or exceeding OEM requirements for the listed applications. It is designed as a direct-fit replacement idler pulley for service work on BMW and Suzuki accessory drive belt systems.
