It uses an internal regulator, has a clockwise rotation, and is listed as an alternator type excluding vacuum pump applications. For buyers matching an existing unit, the key identifiers here are 24 volts, 120 amps, single leg alternator mount, and three-point mounting.\u003c\/p\u003e\n\u003cp\u003eIt is manufactured in Spain and supplied as each, with a 12 month warranty. The mounting dimensions shown are 80mm mount leg thickness, 159mm mount centre to centre, and a 12mm adjusting hole diameter. The shaft diameter is 17mm and the pulley section is not applicable.\u003c\/p\u003e\n\u003cp\u003eThe unit is described as having contained non-recycled copper for fewer impurities and greater performance, along with corrosion resistance for harsh conditions. Those are useful points for commercial vehicles working in demanding environments, but the practical check remains the same: confirm the part number, voltage, amperage, mounting style, and physical dimensions before ordering.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e24V, 120A alternator\u003c\/li\u003e\n\u003cli\u003eBosch brand, new unit\u003c\/li\u003e\n\u003cli\u003eInternal regulator\u003c\/li\u003e\n\u003cli\u003eClockwise rotation\u003c\/li\u003e\n\u003cli\u003eSingle leg mount with three-point fastening\u003c\/li\u003e\n\u003cli\u003eExcludes vacuum pump type\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePart No.: 1986A00974\u003c\/li\u003e\n\u003cli\u003eVoltage: 24V\u003c\/li\u003e\n\u003cli\u003ePower rating \/ charge current: 120A\u003c\/li\u003e\n\u003cli\u003eMount leg thickness: 80mm\u003c\/li\u003e\n\u003cli\u003eMount centre to centre: 159mm\u003c\/li\u003e\n\u003cli\u003eAdjusting hole diameter: 12mm\u003c\/li\u003e\n\u003cli\u003eShaft diameter: 17mm\u003c\/li\u003e\n\u003cli\u003eRotation: CW\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eVerified fitment references\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eM.A.N.

The electrical specification is 24V at 120A, so the replacement needs to match the vehicle’s charging system requirements rather than simply looking similar in shape.\u003c\/p\u003e\n\u003cp\u003eThe mounting setup is important on this unit: single leg alternator mount, three-point mounting, 80mm mount leg thickness, 159mm mount centre to centre, and a 12mm adjusting hole. If any of those points differ from the original unit, the alternator may not line up correctly even if the plug or casing appears close.\u003c\/p\u003e\n\u003cp\u003eThis alternator is listed with an internal regulator and clockwise rotation. It also has a 17mm shaft diameter and is marked as excluding vacuum pump applications, so it should only be considered where those details match the vehicle’s original equipment.\u003c\/p\u003e\n\u003cp\u003eRecommended additional repairs include the V-belt or V-ribbed belt. When replacing an alternator, it is sensible to inspect the belt condition, drive alignment, and any worn mounting hardware at the same time, because those items can affect charging performance and installation quality.\u003c\/p\u003e\n\u003cp\u003eThe fitment references supplied include a range of MAN applications, including MAN TGL, TGM, TGS, TGX, and several MAN bus and engine references. Those references are useful as a guide, but the safest approach is still to confirm the exact vehicle application against the part number and the dimensions listed here.\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 1986A00974 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, Power Rating (Amp) 120, Regulator Type Internal, Shaft Diameter 17mm, Voltage 24, Mount Cnt to Cnt 159mm, Alternator Charge Current [A] 120.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Alternator Type excl. vacuum pump, Packaging length 23.9, Packaging height 20, Product Group 2 ALTERNATORS, Part No. 1986A00974, Brand BOSCH, Description Bosch Alternator 24V 120A, Adjusting Hole Diameter 12, Pin Code IR98.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 24V 120A. Part number 1986A00974 should be checked first. Listed voltage is 24. 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 Single Leg. Regulator type is Internal. Pulley configuration is Not Applicable. 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 1986A00974, 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 24 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 M.A.N. D2676, M.A.N.
