The key checkpoints here are 12V system voltage, 70A output, internal regulator, single leg mount, 5 groove pulley, and the listed mounting dimensions of 58mm, 164mm centre to centre, and 10mm pivot hole diameter.\u003c\/p\u003e\n\u003cp\u003eThe mount and pulley details matter because alternators that look similar can still differ in shaft size, pulley section, bracket spacing, or regulator arrangement. This unit has a 53.5mm pulley outside diameter and a 15mm shaft dimension, so those measurements should be confirmed against the removed part before fitting.\u003c\/p\u003e\n\u003cp\u003eFitment references include Caterpillar, Hino, Komatsu and Toyota applications, including several Toyota Dyna, Hiace, Hilux and industrial listings. That said, matching by application name alone is not enough; the safest approach is to verify the part number, mounting layout, and pulley configuration together.\u003c\/p\u003e\n\u003cp\u003eThe listed warranty is 3 years for passenger use and 1 year for commercial use. If the vehicle or equipment is used commercially, the shorter warranty period applies, so it is worth checking the intended duty cycle before purchase.\u003c\/p\u003e\n\u003cp\u003eAt 4.24kg, this is a substantial rotating electrical component and should be handled as a precision electrical part, not just a mechanical bolt-on. Inspect belts, wiring connections, charge light behaviour, and battery condition when replacing an alternator, as those items can affect the result even when the alternator itself is correct.\u003c\/p\u003e\n\u003cp\u003eIf the removed alternator is an original Denso unit, the Denso style description is a useful starting point, but it is still essential to confirm the exact dimensions and the IR11 pin code where relevant. Small differences in mounting or plug arrangement can change whether the unit is a direct replacement.\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 DXA520 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, Mount Leg Thickness 58mm, Pivot Hole Diameter 10, Pulley Outside Diameter 53.5mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 164mm, Shaft Dimension 15.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA520, Brand OEX, Description OEX Alternator 12V 70A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR11, Power Rating (Amp) 70, Pulley Section 5 Groove, Suits Unit Make Denso.\u003c\/p\u003e\n\u003cp\u003eOEX Alternator 12V 70A Denso Style. Part number DXA520 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 Single 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 DXA520, 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 CATERPILLAR 304.E2 CR, CATERPILLAR 304.E2 CR 2014, CATERPILLAR 304E, CATERPILLAR 304E 2013, HINO DUTRO, HINO DUTRO 2000.
