Application and Buying Notes

The most important checks for this alternator are the Bosch Part No. 1986A00766, 12V system voltage, 180A charge rating, 6 groove pulley, and CW rotation. If any of those differ from the unit being replaced, stop and compare carefully before purchasing.

Mounting details are also critical. This alternator is listed with a pad mount, direct fastening type, 70mm mount leg thickness, and 10mm mount hole diameter. Those measurements affect how the unit sits in the engine bay and whether the bracket arrangement matches the vehicle.

The alternator is described as excl. vacuum pump and uses an internal regulator. That means it is not a universal replacement and should only be considered where the original unit matches those design details. Comparing the removed alternator with the listed specifications is the safest approach.

The listed weight of 8.020kg and packaging dimensions of 23.9 x 20 x 20 are useful for handling and freight planning, but they do not confirm fitment. The deciding factors remain the part number, mounting pattern, pulley configuration, and application details for the vehicle.

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 1986A00766 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.

For part number 1986A00766, 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 180 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm compatibility by matching Bosch Part No. 1986A00766, the 12V 180A specification, 6 groove pulley, CW rotation, pad mount, and the vehicle application details before ordering. Fitment should be checked against the removed alternator and the vehicle’s charging system requirements.
