TOYOTA 13505-17011 Timing Belt Idler Pulley

The TOYOTA 13505-17011 part (superseded/replacement part number: 1350517010) is a genuine timing belt idler sub-assembly (IDLER SUB-ASSY, TIMING BELT, NO.1), serving as a crucial component of the internal combustion engine's timing drive system. Its function is to maintain proper tension and stable belt tracking between the camshaft and crankshaft, preventing belt vibration, slipping, or jumping teeth during the engine cycle.

The idler pulley is manufactured with a high-strength, wear-resistant metal housing and a durable, sealed bearing designed to withstand high RPM, thermal loads, and operational vibrations. Component failure (such as bearing seizure, increased radial play, or squeaking/grinding noise) can cause belt misalignment, excessive wear, or belt snapping, leading to catastrophic engine damage. Therefore, replacing the idler pulley during scheduled timing belt service is strictly recommended.
