OEX Alternator 12V 140A Hitachi Style HXA116

The OEX HXA116 is a new 12V alternator with a 140A power rating, built in a Hitachi style configuration for applications that require a quad leg mount and 6 groove pulley setup. It uses an internal regulator and is listed with pin code IR50, which are important checkpoints when matching the unit to the vehicle.

Key mounting dimensions for this alternator are M8x1.25 / 8 for both the adjusting hole and pivot hole, with a mount centre to centre measurement of 127mm. The pulley outside diameter is 50mm, so the drive setup needs to be checked against the existing unit before ordering.

OEX positions this alternator range as a quality aftermarket option with ISO9001 certified factories and a comprehensive warranty. For passenger use the warranty is 3 years, and for commercial use it is 1 year, which adds useful buying confidence when selecting a replacement alternator by part number and specification.

The listed part number is HXA116 and the unit type is alternator, supplied each. For correct selection, the most reliable matching points are the 12V system, 140A output, Hitachi suit unit make, quad leg mount, 6 groove pulley, and the IR50 pin code.

Application and Buying Notes

Before ordering, compare the part number HXA116, the 12V system, the 140A output, and the Hitachi style mounting with the unit already fitted to the vehicle. These are the most practical checks when replacing an alternator, especially where the vehicle may have had different electrical or mounting variations.

The quad leg mount, 6 groove pulley, and 127mm mount centre to centre measurement should be matched carefully. The adjusting hole and pivot hole are both M8x1.25 / 8, so the fastener size and bracket arrangement need to line up with the existing installation rather than being assumed from the model name alone.

The internal regulator and IR50 pin code are also important identification points. If the plug style or charging control arrangement differs, the alternator may not suit even if the vehicle is otherwise similar. That is why the physical unit, connector, and mounting layout should be checked against the current alternator before purchase.

This OEX unit is new and supplied each, with warranty coverage listed as 3 years for passenger use and 1 year for commercial use. Those details are useful when comparing replacement options, but the final selection should still be made using the vehicle application, the part number, and the measured mounting and pulley details.

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 HXA116 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 HXA116, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include NISSAN SERENA, NISSAN SERENA 2005, NISSAN SERENA 2006, NISSAN SERENA 2007. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm compatibility by checking part number HXA116, the 12V 140A specification, Hitachi style unit make, quad leg mount, 6 groove pulley, IR50 pin code, and the mounting dimensions before ordering.
