It carries part number DXA4057 and is designed with an internal regulator, a single leg alternator mount, and a pulley outside diameter of 63mm with an A section pulley.\u003c\/p\u003e\n\u003cp\u003eThis unit suits Denso applications and is listed with mount leg thickness of 24mm, pivot hole diameter of 10mm, mount centre to centre of 154mm, and adjusting hole thread M8 x 1.25. Those measurements are important when comparing the alternator to the original unit, especially where bracket spacing and mount style must match closely.\u003c\/p\u003e\n\u003cp\u003eOEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with production from ISO certified factories. The alternator is backed by a 3 year passenger \/ 1 year commercial warranty, which is a useful buying point for owners who want a replacement unit with clear coverage terms.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12V alternator with 55A output\u003c\/li\u003e\n\u003cli\u003eNew unit, supplied each\u003c\/li\u003e\n\u003cli\u003eInternal regulator\u003c\/li\u003e\n\u003cli\u003eSingle leg alternator mount\u003c\/li\u003e\n\u003cli\u003eDenso style, suits Denso unit applications\u003c\/li\u003e\n\u003cli\u003e63mm pulley outside diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: DXA4057\u003c\/li\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: 55A\u003c\/li\u003e\n\u003cli\u003eRegulator type: Internal\u003c\/li\u003e\n\u003cli\u003eSuits unit make: Denso\u003c\/li\u003e\n\u003cli\u003eAlternator mount: Single leg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCompatible applications listed\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eAIRMAN PDS100S\u003c\/li\u003e\n\u003cli\u003eAIRMAN PDS100S 2018\u003c\/li\u003e\n\u003cli\u003eCASE CX31B\u003c\/li\u003e\n\u003cli\u003eCASE CX36B\u003c\/li\u003e\n\u003cli\u003eCASE CX50B\u003c\/li\u003e\n\u003cli\u003eCASE CX50B 2007\u003c\/li\u003e\n\u003cli\u003eCASE CX50B 2008\u003c\/li\u003e\n\u003cli\u003eCASE CX50B 2009\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, compare the part number DXA4057 and the physical mounting details with the alternator already fitted to the machine. The key points here are the single leg mount, 154mm mount centre to centre, 24mm mount leg thickness, 10mm pivot hole diameter, and M8 x 1.25 adjusting hole, as these features need to align with the bracket set-up on the vehicle or machine.\u003c\/p\u003e\n\u003cp\u003eThe alternator is a 12V, 55A unit with an internal regulator and a 63mm A section pulley. That combination matters because output capacity, pulley size, and regulator type all need to suit the electrical system and drive arrangement already in place. A mismatch can mean the unit will not mount correctly or may not operate as intended.\u003c\/p\u003e\n\u003cp\u003eThis listing includes a broad application list across compact equipment and small tractors, but the safest approach is still to verify against the exact model, year if known, and the original alternator dimensions. Where the original unit is unavailable, matching the mounting dimensions, pulley section, and unit make as closely as possible is the best way to reduce the risk of ordering the wrong part.\u003c\/p\u003e\n\u003cp\u003eThe alternator is supplied new and weighs 3.18kg. If you are replacing a worn or noisy unit, it is sensible to inspect the belt condition, pulley alignment, and charging system connections at the same time, because a new alternator will still rely on the existing belt drive, wiring, and mounting hardware being in sound condition.\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 DXA4057 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 63mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 154mm, Weight 3.18kg.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. DXA4057, Brand OEX, Description OEX Alternator 12V 55A Denso Style, Adjusting Hole Diameter M8 x 1.25, Pin Code IR74, Power Rating (Amp) 55, Pulley Section A, Suits Unit Make Denso, Alternator Mount Single Leg.\u003c\/p\u003e\n\u003cp\u003eOEX Alternator 12V 55A Denso Style. Part number DXA4057 should be checked first. Listed voltage is 12. Listed output rating is 55.

Pulley configuration is A. 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 DXA4057, 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 55 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include AIRMAN PDS100S, AIRMAN PDS100S 2018, CASE CX31B, CASE CX36B, CASE CX50B, CASE CX50B 2007.
