OEX Alternator 12V 40A Hitachi Style HXA015

The OEX HXA015 is a new 12V alternator rated at 40A, built in a Hitachi style format for applications that call for that unit make and mounting pattern. It uses an internal regulator, a twin leg alternator mount, and a pulley with a 68mm outside diameter, so it is important to match the physical details as well as the part number before ordering.

Key dimensions include 81mm inside mounting legs, 156mm mount centre to centre, an 8mm pivot hole diameter, and an M8x1.25 adjusting hole diameter. Those measurements matter when checking whether the alternator will sit correctly in the bracket assembly and line up with the drive belt system.

This unit is listed under OEX part number HXA015 and is sold individually. It weighs 3.34kg and uses a pulley section A, which are useful checks when comparing against the removed unit or confirming what is currently fitted to the machine or vehicle.

Application and Buying Notes

The most important checks for this alternator are the part number HXA015, the Hitachi style configuration, and the mounting measurements of 81mm inside mounting legs and 156mm mount centre to centre. If those points do not match the unit you are replacing, the alternator may not bolt up correctly even if the electrical rating appears similar.

Because this is a 12V, 40A alternator with an internal regulator, it suits applications built around that charging setup. Confirm the vehicle or machine originally used a 12V system and compare the regulator type, pulley section A, and the 68mm pulley outside diameter against the existing unit before purchase.

The supplied application list includes a range of industrial, forklift, tractor, and light vehicle references, but fitment should still be checked against the exact model and build details. Wear, previous repairs, and non-standard replacements can change the required alternator, so the removed unit remains the best physical comparison where available.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That is useful when planning the purchase, but it does not replace the need to confirm the mounting style, hole sizes, and electrical specification before fitting. The unit is new, not remanufactured, and is sold each rather than as a kit.

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 HXA015 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Inside Mounting Legs 81mm, Pivot Hole Diameter 8, Pulley Outside Diameter 68mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 156mm, Weight 3.34kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. HXA015, Brand OEX, Description OEX Alternator 12V 40A Hitachi Style, Adjusting Hole Diameter M8x1.25, Pin Code IR16, Power Rating (Amp) 40, Pulley Section A, Suits Unit Make Hitachi, Alternator Mount Twin Leg.

OEX Alternator 12V 40A Hitachi Style. Part number HXA015 should be checked first. Listed voltage is 12. Listed output rating is 40. These details form the core reference points used by parts interpreters when confirming the correct replacement.

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

For part number HXA015, 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 40 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ALLIS CHALMERS 5020, ALLIS CHALMERS 6140, GEHL SL4610/4615, HYSTER S40-60XL, ISEKI TE3210, ISEKI TL2700. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using the OEX HXA015 part number, the Hitachi style configuration, the 12V 40A electrical rating, and the listed mounting and pulley measurements before ordering. If the removed alternator differs in mount style, regulator type, or pulley dimensions, do not assume interchangeability.
