It is listed as an alternator type excluding vacuum pump, so the application needs to match that configuration before purchase.\u003c\/p\u003e\n\u003cp\u003eThe unit uses a 6 groove pulley with multi-belt pulley arrangement, a 50mm pulley outside diameter, and a twin leg alternator mount with double pivot lever fastening. Those mounting and pulley details are important when checking interchange, especially where the original unit has the same 12V layout but different bracket or pulley specifications.\u003c\/p\u003e\n\u003cp\u003eIt is manufactured in South Africa and carries a one year warranty. The listed Pin Code is IR122, and the recommended additional repair is a V-Belt\/V-Ribbed Belt where the drive system is being serviced at the same time.\u003c\/p\u003e\n\u003cp\u003eFor buyers comparing replacements, the key identifiers here are Bosch brand, 12V voltage, 120A output, and part number 0124515052. Matching those details against the removed unit is the safest way to confirm whether this alternator is the correct unit for the vehicle application.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBosch brand alternator\u003c\/li\u003e\n\u003cli\u003e12V system with 120A charge current\u003c\/li\u003e\n\u003cli\u003eNew unit, supplied each\u003c\/li\u003e\n\u003cli\u003eInternal regulator\u003c\/li\u003e\n\u003cli\u003e6 groove pulley with multi-belt pulley\u003c\/li\u003e\n\u003cli\u003eTwin leg mount with double pivot lever fastening\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart number: 0124515052\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V\u003c\/li\u003e\n\u003cli\u003eCharge current \/ power rating: 120A\u003c\/li\u003e\n\u003cli\u003eRegulator type: Internal\u003c\/li\u003e\n\u003cli\u003ePulley section: 6 groove\u003c\/li\u003e\n\u003cli\u003ePulley outside diameter: 50mm\u003c\/li\u003e\n\u003cli\u003eMount type: Twin leg\u003c\/li\u003e\n\u003cli\u003eFastening type: Double pivot lever\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment guidance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFitment preview includes BMW 3 applications from 2000 through 2005.\u003c\/li\u003e\n\u003cli\u003eFitment group shown: BMW and BMW 3.\u003c\/li\u003e\n\u003cli\u003eConfirm the removed alternator matches the 12V, 120A, 6 groove, twin leg, and excluded vacuum pump configuration before ordering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eWhen replacing an alternator, the most useful checks are the part number 0124515052, the 12V operating voltage, and the 120A output rating. If the original unit differs in pulley arrangement, mount style, or regulator type, the replacement may not interchange even where the vehicle family appears similar.\u003c\/p\u003e\n\u003cp\u003eThis Bosch unit uses a 6 groove multi-belt pulley with a 50mm outside diameter and a twin leg mount. Those details matter because alternator fitment is often determined by the bracket shape, belt drive layout, and fastening style rather than by brand name alone.\u003c\/p\u003e\n\u003cp\u003eThe alternator is listed as excluding a vacuum pump, so that point needs to be checked carefully on the vehicle and on the removed part. If the existing alternator includes a vacuum pump or a different rear housing arrangement, this unit should not be assumed to suit.\u003c\/p\u003e\n\u003cp\u003eA one year warranty is listed for this part, and it is supplied new rather than remanufactured. If you are renewing the charging system, the recommended additional repair is the V-Belt\/V-Ribbed Belt, which is sensible to inspect when the drive system has wear or contamination.\u003c\/p\u003e\n\u003cp\u003eThe listed fitment preview references BMW 3 applications from 2000 to 2005, but that should still be treated as a guide only. Always verify the removed alternator against the Bosch part number, pin code IR122, and the physical mounting and pulley details before finalising the order.\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 0124515052 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, Power Rating (Amp) 120, Pulley Section 6 Groove, Suits Unit Make Bosch, Alternator Mount Twin Leg, Alternator Charge Current [A] 120, Pulleys with multi-belt pulley, Number of grooves 6.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Packaging length 23.9, Packaging height 20, Product Group 2 ALTERNATORS, Part No. 0124515052, Brand BOSCH, Description Bosch Alternator 12V 120A, Pin Code IR122, Pulley Outside Diameter 50mm, Regulator Type Internal.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 120A. Part number 0124515052 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 Twin Leg. Regulator type is Internal. 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 0124515052, 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. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include BMW 3, BMW 3 2000, BMW 3 2001, BMW 3 2002.
