Toyota 274150W131 — Alternator Pulley with Overrunning Clutch
Overview
Overrunning alternator pulley Toyota 274150W131 dampens auxiliary belt drive oscillations and isolates the alternator rotor from rotational speed fluctuations during rapid engine deceleration. Manufactured from hardened alloy steel, this unit features an internal one-way freewheel clutch mechanism with a needle roller bearing assembly. Technical specifications include 6 ribs designed for a 6PK serpentine belt, M17x1.5 internal mounting thread, outer diameter of 58.5 mm, and total depth of 40.2 mm. The unit incorporates a protective plastic cap and factory-packed high-temperature grease. OEM cross-reference number 27415-0W131 matches exact original equipment dimensions for correct belt alignment across all driven pulleys.
This component fits Toyota Camry XV40, XV50 2.4 and 2.5, RAV4 XA30, XA40 2.0 and 2.4, Highlander XU40 2.7 and 3.5, plus Lexus ES250, ES350, and RX350 models produced between 2006 and 2018 powered by 1AZ-FE, 2AZ-FE, 2AR-FE, and 2GR-FE petrol engines. Replacement becomes necessary when the internal clutch seizes in both rotation directions, during metallic rattling noises upon engine shutdown, or when excessive belt flutter occurs at idle speed. A failed internal mechanism causes premature wear to the automatic belt tensioner assembly and generator bearings.
