It is rated at 150 amps and uses a 12V internal regulator layout, so it is intended for applications where the charging system specification needs to match the vehicle exactly.\u003c\/p\u003e\n\u003cp\u003eKey physical details include a twin-leg alternator mount, M10 mount hole diameter, 10.2 \/ M10 pivot hole diameter, 82mm inside mounting legs, and a 53mm pulley outside diameter. It also uses a 6 groove pulley section and clockwise rotation, which are important checks when comparing against the removed unit.\u003c\/p\u003e\n\u003cp\u003eThis Bosch alternator is identified with pin code IR139 and carries the brand’s own description as a 12V 150A alternator. The feature statement supplied with the part notes that it is made from high quality raw materials for long life and optimal performance, which is a useful reminder to compare the full specification set before ordering.\u003c\/p\u003e\n\u003cp\u003eBecause alternators need to match both electrical output and mounting layout, the safest approach is to verify the part number 1986A00874, voltage, amp rating, pulley style, and mounting measurements against the original unit already fitted to the vehicle.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e12V alternator rated at 150A\u003c\/li\u003e\n\u003cli\u003eInternal regulator type\u003c\/li\u003e\n\u003cli\u003eTwin leg alternator mount\u003c\/li\u003e\n\u003cli\u003e6 groove pulley section\u003c\/li\u003e\n\u003cli\u003eClockwise rotation\u003c\/li\u003e\n\u003cli\u003eBosch part number 1986A00874\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\u003ePart number: 1986A00874\u003c\/li\u003e\n\u003cli\u003eWarranty: 12 months\u003c\/li\u003e\n\u003cli\u003eMount hole diameter: M10\u003c\/li\u003e\n\u003cli\u003ePivot hole diameter: 10.2 \/ M10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePorsche 911\u003c\/li\u003e\n\u003cli\u003ePorsche 911 2004\u003c\/li\u003e\n\u003cli\u003ePorsche 911 2005\u003c\/li\u003e\n\u003cli\u003ePorsche 911 2006\u003c\/li\u003e\n\u003cli\u003ePorsche 911 2007\u003c\/li\u003e\n\u003cli\u003ePorsche 911 2008\u003c\/li\u003e\n\u003cli\u003ePorsche Boxster\u003c\/li\u003e\n\u003cli\u003ePorsche Boxster 2004\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplication and Buying Notes\u003c\/h3\u003e\n\u003cp\u003eBefore ordering, match the removed alternator against the listed details: 12V system voltage, 150A output, internal regulator, twin leg mount, M10 mount hole, 10.2 \/ M10 pivot hole, 82mm inside mounting legs, and 53mm pulley diameter. These measurements are the practical checks that help confirm whether the part will sit and drive correctly in the vehicle.\u003c\/p\u003e\n\u003cp\u003eThe pulley setup also needs close attention. This unit is listed with a 6 groove pulley section and clockwise rotation, so the belt profile and rotation direction should be compared with the existing alternator. If either of those details differs from the original unit, the part may not be suitable even if the mounting points appear similar.\u003c\/p\u003e\n\u003cp\u003ePart number verification is still the most reliable way to confirm the correct alternator. Use Bosch part number 1986A00874 and the vehicle application details together, rather than relying on appearance alone. Alternators can look alike while differing in regulator type, pulley section, or mounting dimensions.\u003c\/p\u003e\n\u003cp\u003eIf you are replacing a faulty charging unit, it is also worth checking the condition of the pulley, plug arrangement, and mounting hardware on the vehicle before installation. The supplied information identifies pin code IR139, but the vehicle connector and physical fit still need to align with the original setup.\u003c\/p\u003e\n\u003cp\u003eWhen comparing options, keep the voltage and amperage in mind. A 12V, 150A alternator is a specific charging specification, so it should be selected to suit the vehicle’s original system requirements. Do not assume a higher output unit will be a direct substitute unless the application details confirm it.\u003c\/p\u003e\n\u003cp\u003eThe supplied warranty is 12 months, which provides a clear reference point for after-sales support, but it does not replace the need to verify fitment carefully. Matching the full specification is the best way to avoid installation delays and return issues.\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 1986A00874 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 Hole Diameter M10, Pivot Hole Diameter 10.2 \/ M10, Pulley Outside Diameter 53mm, Regulator Type Internal, Voltage 12, Product Group 2 ALTERNATORS.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Part No. 1986A00874, Brand BOSCH, Description Bosch Alternator 12V 150A, Inside Mounting Legs 82mm, Pin Code IR139, Power Rating (Amp) 150, Pulley Section 6 Groove, Rotation CW, Alternator Mount Twin Leg, Product Group 1 ROTATING ELECTRICAL.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 150A.
