Detailed Description

Hayden Pulley 5064 is an idler / tensioner pulley used in accessory drive belt systems where stable belt routing is critical. Its steel construction, smooth pulley surface, and OE-matching dimensions help maintain proper belt alignment in Toyota and Lexus engines that use a back idler pulley configuration. This part number is commonly selected for service on Toyota Tundra, Sequoia, 4Runner, and Land Cruiser models, as well as Lexus GS300, GS430, LS400, LS430, LX470, SC300, SC400, SC430, and IS300 applications. The Hayden 5064 also cross-references Continental 49100 and Gates 36119 for the same application.

What It Helps Address

• Noise from a worn or rough idler pulley
• Belt tracking issues caused by pulley wear
• Accessory drive belt vibration
• Uneven pulley surface wear that can affect belt life
• Loss of smooth belt rotation in the tensioner path

Installation Notes and Tips

Verify pulley diameter, width, bore size, and mounting style against the original part before installation. This pulley uses a single mount hole and does not include mounting hardware. Inspect the accessory drive belt, tensioner assembly, and adjacent pulleys for wear at the same time to help avoid repeat service. Confirm vehicle-specific fitment for your Toyota or Lexus application before ordering.

Quality Assurance

Hayden 5064 is specified to meet or exceed OEM requirements for the listed applications. Its steel construction and OE-style dimensions support consistent service replacement in accessory drive belt systems.
