It uses a twin leg mount, internal regulator, 6 groove pulley and 135mm centre-to-centre mount spacing, so matching those physical details is essential before purchase.\u003c\/p\u003e\n\u003cp\u003eThis alternator is listed with an inside mounting legs measurement of 55mm, pivot hole diameter of M10x1.5 \/ 10, adjusting hole diameter of M10x1.5 \/ 10, and a 53mm pulley outside diameter. Those dimensions are the key checkpoints when comparing against the unit already fitted to the vehicle.\u003c\/p\u003e\n\u003cp\u003eThe OEX range is positioned as an aftermarket option with a focus on quality and reliability, and this alternator is backed by a 3 year passenger \/ 1 year commercial warranty.

The 55mm inside mounting legs and M10x1.5 \/ 10 pivot and adjusting holes are practical identifiers that help rule out mismatches.\u003c\/p\u003e\n\u003cp\u003eThe 100A rating and 12V system specification matter because the alternator must suit the vehicle’s charging requirements as well as the mounting layout. If the vehicle uses a different pulley section, different regulator arrangement or different bracket spacing, the alternator may not be suitable even if the model name appears similar.\u003c\/p\u003e\n\u003cp\u003eThis unit weighs 5.4kg and uses a 53mm, 6 groove pulley, so it is worth checking belt alignment and pulley profile against the removed part. In alternator replacement work, the safest approach is to verify every physical point of comparison before the unit is installed.\u003c\/p\u003e\n\u003cp\u003eOEX positions this alternator as a new aftermarket replacement backed by a 3 year passenger \/ 1 year commercial warranty. That warranty support is valuable, but it does not replace the need to confirm the correct application details, particularly where multiple Holden and Opel variants are listed in the fitment data.\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 DXA499 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 55mm, Pivot Hole Diameter M10x1.5 \/ 10, Pulley Outside Diameter 53mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 135mm, Weight 5.4kg.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. DXA499, Brand OEX, Description OEX Alternator 12V 100A Delphi Style, Adjusting Hole Diameter M10x1.5 \/ 10, Pin Code IR127, Power Rating (Amp) 100, Pulley Section 6 Groove, Suits Unit Make Delphi, Alternator Mount Twin Leg.\u003c\/p\u003e\n\u003cp\u003eOEX Alternator 12V 100A Delphi Style. Part number DXA499 should be checked first. Listed voltage is 12. Listed output rating is 100.

Pulley configuration is 6 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 DXA499, 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 100 should be checked carefully.
