OEM 23150-2W200 ALTERNATOR PULLEY FOR NISSAN PATROL – 20CR STEEL OVERRUNNING PULLEY WITH READY STOCK
This alternator pulley, OEM number 23150-2W200, also written 231502W200, is a production line overrunning alternator pulley replacement for Nissan Patrol and related ZD30 diesel platforms. It is the component that transfers drive from the 7PK belt to the alternator while protecting the charging system from the harsh torsional vibration of a 3.0 litre diesel engine. Machined from 20Cr alloy steel at about 0.5 kg per piece, this pulley is held in ready stock and ships worldwide for distributors and workshops that cannot afford charging system downtime. Whether you maintain a Nissan Patrol Y61 in Kazakhstan or Malaysia, or stock Nissan alternator pulleys for the Nigeria and Peru aftermarket, this part is supplied as a direct OE fit that requires no modification.
WHY THE 23150-2W200 ALTERNATOR PULLEY USES AN OVERRUNNING CLUTCH DESIGN
A standard solid pulley turns the alternator at engine speed in both directions of acceleration and deceleration, which loads the belt, the tensioner and the alternator bearings every time the driver changes throttle. The 23150-2W200 alternator pulley is built as an overrunning alternator pulley, also called an alternator decoupler pulley, alternator freewheel clutch pulley or one way clutch pulley. Inside the pulley body, a freewheel mechanism lets the alternator rotor spin at its own speed when the engine rpm drops quickly, so the rotor no longer drags the belt backwards during every gear change. For a Nissan Patrol running a ZD30 turbo diesel, this overrunning action noticeably reduces belt slip and squeal, smooths the shock loads sent into the alternator shaft and front bearing, and extends the service life of both the drive belt and the alternator itself.
VERIFIED FITMENT FOR NISSAN PATROL Y61 AND RELATED ZD30 PLATFORMS
23150-2W200 is the original Nissan part number for this alternator pulley assembly. The primary application is the Nissan Patrol GU Y61 with the 3.0 litre ZD30DDTi turbo diesel engine, a vehicle widely operated across Central Asia, Southeast Asia, Africa and South America. The same pulley also fits the related Nissan ZD30 family, including the Navara D22 3.0 diesel, Terrano II R20, Mistral, Caravan E25 and other Nissan chassis using this alternator mounting, so traders and workshops can serve several popular Nissan models from a single stock keeping unit. Aftermarket catalogues commonly cross this reference with 23150-2W20A, 23150-2W20B and 535005310, and it is listed under leading brands such as SKF, Gates, INA and Dayco equivalents. Before ordering, check the number stamped on the pulley currently fitted to your alternator and confirm that your vehicle carries a 23150-2W200 type overrunning pulley; if your application lists a different reference, send it to our sales team and we will verify compatibility against our alternator pulley range.
20CR ALLOY STEEL – THE MATERIAL THAT KEEPS THE PULLEY TRUE FOR YEARS
The pulley is manufactured from 20Cr alloy steel, a chromium bearing steel grade chosen for this application because it combines a hard, wear resistant surface with the toughness needed in a part that spins on the alternator shaft for the life of the vehicle. The belt contact faces and the clutch bore are machined to a controlled finish so the 7 rib belt tracks smoothly and the freewheel mechanism engages without binding. Each pulley weighs about 0.5 kg, matching the mass of the original Nissan assembly, which keeps the rotating balance of the alternator unchanged. For a component that sits in a hot engine bay and carries continuous belt load, the 20Cr material delivers the dimensional stability that prevents premature belt wear and pulley noise in daily service.
