It is an alternator type excluding vacuum pump, with an internal regulator, single leg mount, and three-point mounting arrangement. Those details matter when matching the unit to the vehicle and checking the mounting layout before purchase.\u003c\/p\u003e\n\u003cp\u003eThis unit has a 77mm pulley outside diameter, a 9 groove pulley section, a 10mm pivot hole diameter, and a 12mm adjusting hole diameter. The mounting leg thickness is 80mm. These are the kinds of dimensions that need to line up with the existing alternator setup, especially where belt alignment and bracket fit are involved.\u003c\/p\u003e\n\u003cp\u003eBosch lists this alternator as manufactured in Spain and supplied with a 12 month warranty. The unit weighs 8kg and is sold each. It is designed for use with a V-Belt or V-Ribbed Belt as a recommended additional repair item, so belt condition should be checked at the same time as the alternator installation.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12V alternator with 150A charge current\u003c\/li\u003e\n\u003cli\u003eBosch part number 1986A00947\u003c\/li\u003e\n\u003cli\u003eInternal regulator\u003c\/li\u003e\n\u003cli\u003eSingle leg alternator mount\u003c\/li\u003e\n\u003cli\u003eThree-point mounting\u003c\/li\u003e\n\u003cli\u003e9 groove pulley section\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBrand: Bosch\u003c\/li\u003e\n\u003cli\u003eProduct type: Alternator\u003c\/li\u003e\n\u003cli\u003eVoltage: 12V\u003c\/li\u003e\n\u003cli\u003ePower rating: 150A\u003c\/li\u003e\n\u003cli\u003eAlternator charge current: 150A\u003c\/li\u003e\n\u003cli\u003ePart No.: 1986A00947\u003c\/li\u003e\n\u003cli\u003eRegulator type: Internal\u003c\/li\u003e\n\u003cli\u003eAlternator mount: Single leg\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment guidance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFitment data supplied includes Mercedes-Benz Atego applications.\u003c\/li\u003e\n\u003cli\u003eThe fitment listing also includes Mercedes-Benz Atego 2 applications.\u003c\/li\u003e\n\u003cli\u003eMercedes-Benz is the only make shown in the supplied fitment data.\u003c\/li\u003e\n\u003cli\u003eYear references visible in the fitment preview include 1998, 1999, 2000, 2001, 2002, 2003, and 2004.\u003c\/li\u003e\n\u003cli\u003eUse the part number 1986A00947 and the mounting and pulley details to confirm the correct replacement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, confirm the alternator part number 1986A00947 against the old unit and check that the vehicle uses a 12V charging system with a 150A alternator. The internal regulator, single leg mount, and three-point mounting layout all need to match the existing installation, not just the electrical rating.\u003c\/p\u003e\n\u003cp\u003eThe pulley details are important on this Bosch unit. It has a 77mm outside diameter and a 9 groove pulley section, so belt alignment and belt style should be checked carefully. If the current belt is worn, the recommended additional repair item is a V-Belt or V-Ribbed Belt, which is worth inspecting at the same time.\u003c\/p\u003e\n\u003cp\u003eMounting dimensions should be checked before fitting. The alternator has an 80mm mount leg thickness, a 10mm pivot hole diameter, and a 12mm adjusting hole diameter. If these figures do not correspond with the vehicle bracket and adjustment arrangement, the alternator may not install correctly even if the electrical specification looks suitable.\u003c\/p\u003e\n\u003cp\u003eThis alternator is listed as excluding a vacuum pump, so it is important to compare the existing assembly rather than assuming interchange from appearance alone. The supplied fitment information points to Mercedes-Benz Atego and Atego 2 applications, but the correct match still needs to be confirmed by part number and the vehicle’s charging system details.\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 1986A00947 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 12 Months, Mount Leg Thickness 80mm, Pivot Hole Diameter 10, Pulley Outside Diameter 77mm, Regulator Type Internal, Alternator Mount Single Leg, Fastening Type Three-point mounting, Recommended additional repairs V-Belt\/V-Ribbed Belt.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Packaging width 20, Manufactured in Spain, Product Group 2 ALTERNATORS, Part No. 1986A00947, Brand BOSCH, Description Bosch Alternator 12V 150A, Adjusting Hole Diameter 12, Pin Code IR139, Power Rating (Amp) 150.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 150A. Part number 1986A00947 should be checked first. Listed voltage is 12. Listed output rating is 150. 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 9 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 1986A00947, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003eAvailable application references include MERCEDES-BENZ ATEGO, MERCEDES-BENZ ATEGO 1998, MERCEDES-BENZ ATEGO 1999, MERCEDES-BENZ ATEGO 2.
