Toyota 274150W042 — Alternator Pulley with Clutch
Overview
Alternator freewheel clutch pulley Toyota 274150W042 transfers rotational torque from the crankshaft to the alternator rotor while dampening belt drive vibrations. The overrunning clutch unit absorbs rotational irregularities, reducing mechanical stress on the poly-V belt and preventing belt slippage. Technical specifications include a 7-rib profile for 7PK belts, an inner diameter of 17 mm, an outer diameter of 59.2 mm, a width of 41.0 mm, and an M17x1.5 internal thread. The construction features a machined steel body, an integrated needle roller bearing, synthetic rubber seals, and a plastic protective end cap. Original equipment reference numbers comprise Toyota 27415-0W042, 274150W040, 274150W041, and 2741528010.
This component fits Denso alternators mounted on Toyota RAV4 III (2005–2012), Toyota Camry XV40 2.4 (2006–2011), Toyota Avensis T250 / T270 (2003–2015), Toyota Previa, and Toyota Corolla E150 models equipped with 2.0L and 2.4L petrol engines (engine codes 1AZ-FE and 2AZ-FE). Average service life spans 100000 to 120000 km. Replacement becomes necessary when the internal clutch seizes, slips in both rotational directions, generates grinding or squealing noises during engine startup, or causes excessive drive belt flutter at idle speed.
