The alternator uses a single leg mount, 169mm mount centre to centre, and 58mm mount leg thickness, so matching the bracket and bolt spacing is essential before fitting.\u003c\/p\u003e\n\u003cp\u003eElectrical compatibility matters as much as the mounting pattern. This unit is a 12V alternator with a 140A output and internal regulator, so it should only be matched to systems that call for those specifications. The pulley is an 8 groove design with a 62mm outside diameter, which should also be compared against the existing unit.\u003c\/p\u003e\n\u003cp\u003eBecause the listing is marked no warranty, it is worth confirming every identifying detail before purchase. The pin code is IR7, the shaft dimension is 17, and the unit is listed as new. Those details help separate similar-looking alternators that may not interchange even when the overall shape appears close.\u003c\/p\u003e\n\u003cp\u003eIf you are cross-checking against a removed unit, compare the old alternator’s tag, pulley, plug style, and mount layout rather than relying on appearance alone. Alternators can share a family resemblance while differing in regulator type, pulley section, or mounting dimensions, and those are the details that determine whether the replacement will suit the machine.\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 DXA4091 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 No Warranty, Pin Code IR7, Pulley Outside Diameter 62mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 169mm, Insulated Return No, Shaft Dimension 17.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. DXA4091, Brand DENSO, Description Denso Alternator 12V 140A, Mount Leg Thickness 58mm, Power Rating (Amp) 140, Pulley Section 8 Groove, Suits Unit Make Denso, Alternator Mount Single Leg, New \/ Reman. New.\u003c\/p\u003e\n\u003cp\u003eDenso Alternator 12V 140A. Part number DXA4091 should be checked first. Listed voltage is 12. Listed output rating is 140. 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 8 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 DXA4091, 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 140 should be checked carefully.
