It is a new alternator with an internal regulator, a clockwise rotation, and an alternator type listed as excl. vacuum pump, so it suits buyers who need those exact physical and electrical details matched before purchase.\u003c\/p\u003e\n\u003cp\u003eMounting and drive details are specific: inside mounting legs are 56mm, mount centres are 164mm, mount centres B are 172mm, and the pulley is a 5 groove multi-belt type with a 57mm outside diameter. Those measurements matter when replacing a charging system component, because alternators that look similar can differ in mounting pattern or pulley arrangement.\u003c\/p\u003e\n\u003cp\u003eThe listed application notes state it is to suit Holden with Z22YH engine.

This unit is Bosch 0124425053, rated at 12V and 120A, with a 5 groove pulley and internal regulator. If your original alternator differs in any of those areas, the part may not be a direct match even if the vehicle appears in the fitment list.\u003c\/p\u003e\n\u003cp\u003eThe alternator is described as pad mounted with direct fastening, inside mounting legs of 56mm, and mount centres of 164mm with mount centres B of 172mm. Those dimensions should be compared with the existing unit or the vehicle’s charging system before ordering, particularly where previous repairs or part substitutions may have changed the installed component.\u003c\/p\u003e\n\u003cp\u003eThe listed application notes point to Holden with Z22YH engine, and the fitment list also includes Holden Astra, Holden Zafira, Saab 9-3, and Saab 9-3X references. Because vehicle ranges can include different charging system variants, the safest approach is to verify the existing alternator label, pulley groove count, mounting points, and engine code together.\u003c\/p\u003e\n\u003cp\u003eThis alternator is a new Bosch unit, not a remanufactured one, and the notes mention premium bearings, non-recycled copper, and a regulator designed for the vehicle application. Those are useful build details, but they do not replace physical confirmation of the unit already fitted to the vehicle.\u003c\/p\u003e\n\u003cp\u003eIf you are comparing units, the most reliable identifiers here are part number 0124425053, 12V output, 120A charge current, CW rotation, and the 5 groove multi-belt pulley. Matching those details gives you a much better chance of selecting the correct replacement the first time.\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 0124425053 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 One Year, Inside Mounting Legs 56mm, Pin Code IR120, Power Rating (Amp) 120, Pulley Section 5 Groove, Rotation CW, Voltage 12, Mount Cnt to Cnt 164mm.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Alternator Charge Current [A] 120, Pulleys with multi-belt pulley, Number of grooves 5, Packaging length 23.9, Packaging height 20, Product Group 2 ALTERNATORS, Part No. 0124425053, Brand BOSCH, Description Bosch Alternator 12V 120A.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 120A. Part number 0124425053 should be checked first. Listed voltage is 12. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Pad. 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 0124425053, 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 120 should be checked carefully.
