Genuine Alternator 12V 180A JR3Z10346D

This Genuine Alternator is a 12V, 180A unit supplied as new, with internal regulation and a 6 groove pulley. It is listed with part number JR3Z10346D and is identified as an OE product in the Genuine Products range.

The alternator is described as a twin leg mount with inside mounting legs measuring 57mm, a pivot hole diameter of M10x1.5 / 11, and an adjusting hole diameter of 10mm. It weighs 7.6kg and is supplied as each, which makes the physical mounting details important when comparing it to the original unit.

A 66.5mm pulley outside diameter and Denso unit make-up are also listed, along with pin code IR187. These details matter when you are matching the replacement to the vehicle’s charging system and mounting arrangement, particularly where the original alternator needs to be cross-checked by part number and dimensions rather than by appearance alone.

The unit carries a one year warranty and sits in the rotating electrical product group. For buyers replacing a worn alternator, the key points to confirm are the 12V system, 180 amp output, internal regulator, 6 groove pulley, and the JR3Z10346D part number.

Application and Buying Notes

When replacing an alternator, the most reliable starting point is the part number. JR3Z10346D is the clearest identifier here, and it should be matched with the vehicle application, mounting layout and pulley specification before purchase. The alternator is 12V and rated at 180A, so it is intended for a charging system designed around those figures.

Mounting details are just as important as electrical output. This unit uses a twin leg mount, with inside mounting legs of 57mm, a pivot hole diameter of M10x1.5 / 11 and an adjusting hole diameter of 10mm. If those dimensions do not line up with the original alternator or bracket arrangement, the unit should not be assumed to fit.

The pulley specification also needs checking. A 66.5mm outside diameter and 6 groove pulley section are listed, which means belt alignment and belt type must suit the vehicle’s original setup. An alternator can look similar from the outside and still be wrong if the pulley count, pulley size or regulator arrangement differs.

The regulator is internal, the unit is new, and it is identified as suitable for a Denso unit make-up. Those are useful comparison points for replacement work, but they do not replace vehicle-specific confirmation. If the original alternator has a different regulator style, mounting pattern or pulley arrangement, measure and compare carefully before ordering.

For practical workshop use, the weight of 7.6kg is also worth noting when handling and fitting the unit. It is supplied with a one year warranty, which provides a defined period of coverage, but the correct application still needs to be confirmed from the vehicle details and the removed alternator.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number JR3Z10346D helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

For part number JR3Z10346D, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility using the part number JR3Z10346D, the 12V 180A specification, twin leg mounting details, 6 groove pulley, and the listed Ford / Ford Mustang application information before ordering.
