Application and Buying Notes

Before ordering, check the Bosch part number 0986041750 and OEM number 12317508054 against the old alternator and the vehicle application. The fitment list supplied includes BMW and Land Rover applications, but the exact vehicle match still needs to be confirmed by part number, mounting style, pulley section, and rotation.

The 150A output and 12V system rating should be matched to the vehicle’s charging requirements. The alternator is listed with a 7 groove pulley, 49mm pulley outside diameter, clockwise rotation, and a single leg flange mount, so those physical details must line up with the original unit.

This alternator is noted as water cooled and as an alternator type excl. vacuum pump. That is important because cooling arrangement and accessory layout can affect interchange, even when the vehicle make appears in the fitment list.

If the vehicle has had previous repairs or conversion work, take extra care with the belt system and mounting point. The listing also notes recommended additional repairs as V-Belt/V-Ribbed Belt, which is a useful reminder to inspect the belt condition when replacing the alternator.

The internal regulator and reduction drive are part of the unit’s specification, so the replacement should be considered as a complete match to the electrical and mechanical design rather than only a visual match. Confirm the pin code IR103 where relevant to your application checks.

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 0986041750 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Power Rating (Amp) 150, Pulley Section 7 Groove, Rotation CW, Voltage 12, Alternator Mount Single Leg, OEM Number 12317508054, Fastening Type Flange mounting.

Additional published details for cross-checking include Alternator Type excl. vacuum pump, Distance from pulley to the alternator 41, Packaging length 23.9, Packaging height 20, Product Group 2 ALTERNATORS, Part No. 0986041750, Brand BOSCH, Description Bosch Alternator 12V 150A, Pin Code IR103.

Bosch Alternator 12V 150A. Part number 0986041750 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.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 0986041750, 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.

Available application references include BMW 5, BMW 5 1996, BMW 5 1997, BMW 5 1998, LAND ROVER RANGE ROVER, LAND ROVER RANGE ROVER 2002. 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: Confirm fitment using part number 0986041750, OEM number 12317508054, and the listed application details before purchase. Do not rely on vehicle make alone; check voltage, amperage, pulley section, rotation, mount type, and whether the original unit is water cooled and excl. vacuum pump.
