OEX Alternator 12V 140A Hitachi Style HXA115

The OEX Alternator HXA115 is a new 12V unit rated at 140A, built in a Hitachi style with a quad leg alternator mount. It uses an internal regulator and a 7 groove pulley, with a pulley outside diameter of 56mm and an inside mounting leg measurement of 58mm.

This alternator is listed with OEM number LR1140-801-PO and adjusting hole diameter M8. Those identifiers are the most useful checks when comparing against an existing unit, especially where the vehicle application has variations across different build dates or charging system setups.

OEX positions this alternator range as an aftermarket option for buyers wanting a replacement rotating electrical component with clear identification details. The unit is supplied each, carries part number HXA115, and is backed by a 3 year passenger / 1 year commercial warranty.

Application and Buying Notes

When comparing this alternator, start with the part number HXA115 and the OEM reference LR1140-801-PO. Those identifiers are the strongest checks for matching the replacement unit to the one already fitted. The alternator is a 12V, 140A unit, so it is intended for systems that match that electrical rating rather than lower output or different voltage setups.

Physical fit is just as important as output. This unit is described as Hitachi style with a quad leg alternator mount, 58mm inside mounting legs, a 7 groove pulley, a 56mm pulley outside diameter, and an M8 adjusting hole diameter. If any of those points differ from the original alternator, the part should be checked carefully before purchase or installation.

The alternator is new and supplied with an internal regulator. That matters where the original charging system is configured for an internally regulated unit, because regulator type is one of the details that can stop a correct-looking alternator from fitting properly or working as intended.

For buyers working on Nissan applications, the available fitment preview includes Cube and Note listings across the model years shown in the fitment section. Even so, vehicle name alone is not enough for a safe match. Always confirm the existing alternator shape, mount style, pulley count, and the relevant part numbers before ordering.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That is useful context when choosing between options, but it should sit alongside the fitment checks rather than replace them. A correct electrical rating and correct mounting arrangement are both needed for a proper replacement.

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 HXA115 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.

Additional published details for cross-checking include Part No. HXA115, Brand OEX, Description OEX Alternator 12V 140A Hitachi Style, Adjusting Hole Diameter M8, Pin Code IR50, Pulley Outside Diameter 56mm, Regulator Type Internal, Voltage 12, New / Reman. New.

OEX Alternator 12V 140A Hitachi Style. Part number HXA115 should be checked first. Listed voltage is 12. Listed output rating is 140. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number HXA115, 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.

Compatibility note: Confirm fitment by matching part number HXA115 and OEM number LR1140-801-PO against the original alternator, then verify the 12V rating, 140A output, Hitachi style, quad leg mount, 58mm inside mounting legs, M8 adjusting hole diameter, and 7 groove pulley before ordering.
