Bosch Alternator 12V 140A, Part No. 1986A00875

The Bosch alternator listed here is a new 12V, 140A unit with internal regulator and clockwise rotation. It is identified by part number 1986A00875 and is supplied as an alternator excluding vacuum pump, so the application needs to match that configuration before purchase.

Key mounting details include a twin leg alternator mount, 80mm inside mounting legs, 164mm centre-to-centre mounting dimension, 11mm adjusting hole diameter and a 17mm shaft diameter. The note also records a shaft length of 21.5mm, which is important when comparing against the unit being replaced.

This alternator is described as suitable for Bosch units and carries a 12 month warranty. The feature note states it contains non-recycled copper, which is relevant for buyers comparing component quality as well as physical fitment.

Fitment references supplied with the listing include Fiat Ducato and Iveco Daily applications across multiple model years, but the exact vehicle match still needs to be confirmed against the part number, mounting dimensions and alternator type before ordering.

Application and Buying Notes

Use the part number 1986A00875 first, then compare the alternator mounting layout, because the listed dimensions are specific: twin leg mount, 80mm inside mounting legs, 164mm mount centre to centre, 11mm adjusting hole and 17mm shaft diameter. Those measurements matter as much as the 12V 140A electrical rating when checking a replacement unit.

The alternator is noted as excluding a vacuum pump, so it should only be considered where the original unit shares that arrangement. A vehicle may be listed in the fitment references and still require a different alternator if the mounting style, pulley arrangement or accessory configuration is not the same.

The current rating is 140A and the regulator type is internal, which are important checks for the charging system setup on the vehicle. The pulley section is marked not applicable, so do not assume a pulley specification beyond the details provided here.

If you are replacing a worn alternator, the listing also recommends additional attention to the V-belt or V-ribbed belt. That is practical because belt condition and alternator installation are closely linked, especially where the charging system has been apart for service.

This unit is supplied new and carries a 12 month warranty, but the safest purchase is still the one matched by part number and measurements. When in doubt, compare the old unit in hand before fitting, including the shaft length of 21.5mm and the fastening type recorded as double pivot lever.

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 1986A00875 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 1986A00875, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FIAT DUCATO, FIAT DUCATO 2006, FIAT DUCATO 2007, FIAT DUCATO 2008, IVECO DAILY, IVECO DAILY 2004. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Please confirm compatibility using part number 1986A00875, the 12V 140A specification, the twin leg mount dimensions, and whether your original alternator is the version excluding a vacuum pump. Fitment references for Fiat Ducato and Iveco Daily are provided as application guidance only and should be checked against the vehicle and removed unit.
