It is listed with a 5 groove pulley, a 59mm pulley outside diameter, and a twin leg alternator mount, so the physical mounting and drive details need to match the vehicle before purchase.\u003c\/p\u003e\n\u003cp\u003eThis alternator is identified as Part No. HXA025 and is specified with an 81mm inside mounting leg measurement, 175mm mount centre to centre, and an M8 x 1.25 adjusting hole diameter. Those dimensions are the key checkpoints when comparing against the existing unit, especially where the original alternator has the same Hitachi-style layout.\u003c\/p\u003e\n\u003cp\u003eOEX states its products are sourced from Original Equipment Manufacturers and aftermarket suppliers, with factories that are ISO9001 certified to support engineering, testing, and quality control procedures.

Those details are the practical fitment checks that matter most when replacing a Hitachi-style alternator.\u003c\/p\u003e\n\u003cp\u003eThe pulley specification also matters. This unit has a 59mm outside diameter pulley with a 5 groove section, so the belt style on the vehicle must match. If the pulley section or mount layout is different, the alternator may not suit even if the electrical rating looks close.\u003c\/p\u003e\n\u003cp\u003eBecause this is an internal regulator alternator, it should only be used where that regulator type is appropriate for the vehicle’s charging system. Matching the alternator brand style alone is not enough; the application, mounting pattern, pulley arrangement, and regulator setup all need to align with the existing unit.\u003c\/p\u003e\n\u003cp\u003eThe listed weight is 5.3kg, which can be useful when comparing to a removed alternator or confirming you are dealing with the same general unit type. If there is any doubt, compare the part number HXA025 and the physical dimensions side by side with the old alternator before fitting.\u003c\/p\u003e\n\u003cp\u003eOEX backs this product with a 3 year passenger and 1 year commercial warranty, but warranty coverage does not replace fitment checking. Confirming the correct application first is the safest way to avoid delays, returns, or charging-system mismatches once the part arrives.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number HXA025 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.\u003c\/p\u003e\n\u003cp\u003eRelevant 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 59mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 175mm, Weight 5.3kg.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. HXA025, Brand OEX, Description OEX Alternator 12V 70A Hitachi Style, Adjusting Hole Diameter M8 x 1.25, Pin Code IR4, Power Rating (Amp) 70, Pulley Section 5 Groove, Suits Unit Make Hitachi, Alternator Mount Twin Leg.\u003c\/p\u003e\n\u003cp\u003eOEX Alternator 12V 70A Hitachi Style. Part number HXA025 should be checked first. Listed voltage is 12. Listed output rating is 70. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Twin Leg. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.\u003c\/p\u003e\n\u003cp\u003eFor part number HXA025, 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.\u003c\/p\u003e\n\u003cp\u003eFor a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include SUBARU LEGACY, SUBARU LEGACY 1989, SUBARU LEGACY 1990, SUBARU LEGACY 1991. 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Please confirm compatibility by checking the part number HXA025, the Hitachi style application, the 12V 70A rating, and the mounting and pulley dimensions against the original alternator before ordering.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat is the part number for this alternator?\u003c\/h4\u003e\n\u003cp\u003eThe part number supplied is HXA025.\u003c\/p\u003e\n\u003ch4\u003eWhat voltage and output does it have?\u003c\/h4\u003e\n\u003cp\u003eIt is a 12V alternator rated at 70A.\u003c\/p\u003e\n\u003ch4\u003eIs the regulator internal or external?\u003c\/h4\u003e\n\u003cp\u003eThis alternator has an internal regulator.\u003c\/p\u003e\n\u003ch4\u003eWhat type of pulley does it use?\u003c\/h4\u003e\n\u003cp\u003eIt has a 5 groove pulley with a 59mm outside diameter.\u003c\/p\u003e\n\u003ch4\u003eWhat mounting details should I check before buying?\u003c\/h4\u003e\n\u003cp\u003eCheck the twin leg mount, 81mm inside mounting legs, 175mm mount centre to centre, 8mm pivot hole diameter, and M8 x 1.25 adjusting hole diameter against the existing unit.\u003c\/p\u003e\n\u003ch4\u003eWhat warranty is listed for this alternator?\u003c\/h4\u003e\n\u003cp\u003eThe listed warranty is 3 year passenger and 1 year commercial.\u003c\/p\u003e","brand":"OEX","offers":[{"title":"Default Title","offer_id":56888686411936,"sku":"A9337657","price":686.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0275\/5058\/0875\/files\/7ui5ILZBkVkmRZiNq2arrQ_0cf4e01c-c09f-4b26-9019-c6f8b2187cdd.jpg?v=1775121196","url":"https:\/\/www.micksgonebush.com.au\/products\/a9337657-oex-alternator-12v-70a-hitachi-style","provider":"Micks Gone Bush","version":"1.0","type":"link"}
