Detailed Description

SKF TBP88008 is an engine timing idler bearing designed for timing belt systems that require consistent belt control. The pulley’s compact dimensions and sealed bearing design help support stable operation in Subaru timing assemblies, including Subaru Impreza, Legacy, Outback, Baja, and Forester applications listed here. This part cross-references OE part number 13073AA220 for the same application.

For Subaru Impreza, Legacy, Outback, and Baja models, the TBP88008 is listed with housing assembly notes for the upper left position. For the 2004 Subaru Forester, it is listed as a lower engine timing idler bearing with housing assembly. Use the exact vehicle and position details below to confirm application before ordering.

Vehicle Fitment

What It Helps Address

• Timing belt noise caused by worn pulley bearings
• Irregular belt tension in the engine timing system
• Premature timing component wear from bearing drag
• Belt tracking issues related to a failing idler bearing
• Service replacement for Subaru timing belt tensioner pulley applications

Installation Notes and Tips

Confirm the vehicle year, model, and position against the fitment list before installation. Inspect the timing belt, related pulleys, and housing assembly for wear at the same time, since a worn adjacent component can shorten service life. Follow the vehicle service procedure and torque specifications for the timing system.
