It is listed with a single leg alternator mount, internal regulator, A section pulley, and a 74mm pulley outside diameter, so the key matching points are not just voltage and amperage but also the physical mounting and pulley details.\u003c\/p\u003e\n\u003cp\u003eThis alternator is identified with part number DXA4040 and pin code IR74. The listed mounting dimensions include 24mm mount leg thickness, 10mm pivot hole diameter, M8x1.25 adjusting hole diameter, and 138mm mount centre to centre. Those measurements are the sort of details that matter when replacing a unit on a machine that already has a Denso-style alternator fitted.\u003c\/p\u003e\n\u003cp\u003eOEX states that its products are sourced from original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified. The unit is covered by a 3 year passenger \/ 1 year commercial warranty, and the alternator weight is listed at 3.7kg. For buyers comparing replacements, those details help confirm that the correct physical and electrical unit is being selected before installation.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12V, 45A alternator\u003c\/li\u003e\n\u003cli\u003eNew unit\u003c\/li\u003e\n\u003cli\u003eDenso style\u003c\/li\u003e\n\u003cli\u003eInternal regulator\u003c\/li\u003e\n\u003cli\u003eSingle leg alternator mount\u003c\/li\u003e\n\u003cli\u003eA section pulley\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: OEX\u003c\/li\u003e\n\u003cli\u003eProduct type: Alternator\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V\u003c\/li\u003e\n\u003cli\u003ePower rating: 45A\u003c\/li\u003e\n\u003cli\u003eUnit of measure: Each\u003c\/li\u003e\n\u003cli\u003eSuits unit make: Denso\u003c\/li\u003e\n\u003cli\u003eAlternator mount: Single leg\u003c\/li\u003e\n\u003cli\u003eRegulator type: Internal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment guidance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eListed fitment support includes equipment from Active, Airman, Ammann, ASV, Bobcat, Case, Caterpillar, Cub Cadet, Daihatsu, Dynapac, Eurocomach, Hitachi, IHI, JCB, John Deere, Kobelco, Komatsu and Kubota.\u003c\/li\u003e\n\u003cli\u003eSample applications listed include Bobcat 322, 323, 324, 325, 328, 329, 418, 425, 428, 463, B200 and E08.\u003c\/li\u003e\n\u003cli\u003eOther sample applications listed include Case 1825B, CX75SR and CX80; Caterpillar 300.9D, 304C, 304CCR, 305.5DCR, 305C, 305CCR, 305DCR and 904B; and Kubota B21, B26, BX22, BX23LB, BX25 and several D-series engines.\u003c\/li\u003e\n\u003cli\u003eHitachi sample applications listed include EX12, EX15, EX25-2, EX30-2, EX35-2, LX15, LX20, LX30, LX40, ZW40, ZW50 and ZX10U-2.\u003c\/li\u003e\n\u003cli\u003eJohn Deere sample applications listed include 15, 17D, 3029D, 317, 35 ZTS, 35C ZTS, 425, 445, 455, 50 ZTS, 50C ZTS and 5310N.\u003c\/li\u003e\n\u003cli\u003eKomatsu sample applications listed include FG10, FG10-10, FG14, FG14-10, FG15\/10, FG15DT-15, FG18D, L-15, PC30MR-2, PC30MRX, PC35R-8 and SK05J-2.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, compare the part number DXA4040, the Denso-style form, and the physical mounting details against the unit being replaced. The listed measurements of 24mm mount leg thickness, 10mm pivot hole diameter, M8x1.25 adjusting hole diameter, and 138mm mount centre to centre are practical checkpoints because alternators that look similar can still differ in the way they bolt up.\u003c\/p\u003e\n\u003cp\u003eThe electrical rating is 12V at 45A, so it is important to match the system voltage and ensure the output is appropriate for the machine. The alternator also uses an internal regulator, which should be checked against the existing setup, since regulator type can affect whether the replacement is suitable without extra changes.\u003c\/p\u003e\n\u003cp\u003eThe pulley details matter as well. This unit has a 74mm outside diameter pulley with an A section belt profile, so the belt and drive arrangement should be checked carefully before purchase. The shaft dimension is listed as 17, and the pin code is IR74, which are useful identifiers when confirming the correct style against a removed sample or the existing alternator.\u003c\/p\u003e\n\u003cp\u003eThis alternator is listed as suitable for Denso applications, but fitment should still be confirmed against the specific machine model, engine, or installed alternator part number. The supplied fitment support covers a wide range of compact equipment and machinery, so matching by application alone is not enough if the existing unit differs in mounting, pulley or regulator arrangement.\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 DXA4040 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 24mm, Pivot Hole Diameter 10, Pulley Outside Diameter 74mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 138mm, Shaft Dimension 17.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA4040, Brand OEX, Description OEX Alternator 12V 45A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR74, Power Rating (Amp) 45, Pulley Section A, Suits Unit Make Denso.\u003c\/p\u003e\n\u003cp\u003eOEX Alternator 12V 45A Denso Style.
