Application and Buying Notes

Before ordering, confirm that your vehicle matches the part number 1986A00879 and the application details shown for Porsche 911, Boxster, and Cayman references in the fitment data. Alternators are not interchangeable just because they are 12V units, so the mounting arrangement and alternator type must also line up with the vehicle.

This Bosch unit is rated at 150A, which is the main electrical output figure to compare against the original part. If the original alternator has a different charge current, mounting style, or design arrangement, the replacement may not be suitable even if the vehicle model sounds similar.

The listed fastening type is Double Pivot Lever and the alternator type is excl. vacuum pump. Those are important checkpoints during identification because mounting style and accessory design can differ between engine variants and model years. Check the existing unit carefully before purchase.

The recommended additional repair is a V-Belt or V-Ribbed Belt. In practice, it is sensible to inspect the belt condition, belt alignment, and related drive components at the same time, especially when fitting a replacement alternator into a worn charging system.

If you are matching a failed alternator, compare the original part number, connector arrangement, belt drive setup, and physical mounting points against the vehicle before fitting. That approach reduces the risk of ordering the wrong rotating electrical part and having the vehicle off the road longer than necessary.

Before 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.

For workshop, fleet, and equipment applications, accurate identification of part number 1986A00879 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.

Bosch Alternator 12V 150A. Part number 1986A00879 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.

For part number 1986A00879, 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.

For 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.

Compatibility note: Confirm fitment using the part number 1986A00879, the 12V 150A specification, and the vehicle application details before purchase. If your vehicle’s mounting style, alternator type, or belt drive arrangement differs, do not assume the part will fit.
