Bosch Alternator 24V 100A Internal Regulated 1986A00544

The Bosch Alternator 24V 100A is a new alternator with internal regulation, supplied as an each unit and identified by part number 1986A00544. It is listed as a Bosch unit with an OEM number of 0124655205, which gives you a practical reference point when comparing the replacement against the original part already fitted.

This alternator is a 24 volt, 100 amp unit with an 8 groove pulley, a 72mm pulley outside diameter, and pad mount fitment. It is described as direct fastening and excludes a vacuum pump, so the physical layout and mounting style need to match the vehicle or machine application before purchase.

The unit is manufactured in Spain and carries a one year warranty. For buyers comparing alternators in workshop conditions, the key identifiers here are the 24V system voltage, 100A output, 8 groove multi-belt pulley, internal regulator, mount leg thickness of 85mm, and mount centre to centre measurement of 155mm.

Application and Buying Notes

Before ordering, compare the alternator part number 1986A00544 and the OEM number 0124655205 against the unit being replaced. These identifiers are the safest starting point when a vehicle or machine uses the same Bosch alternator family, especially where the application list includes mixed equipment such as BRUKS, DOOSAN/DAEWOO, IRIZAR, MOXY, SCANIA and TEREX O&K.

Check the mounting details carefully. This alternator is a pad mount, direct fastening design with a 9mm mount hole diameter, 85mm mount leg thickness, and 155mm mount centre to centre. If the brackets, spacing or fastening style differ, the alternator may not sit correctly even if the electrical rating looks similar.

The pulley setup is also important. This unit uses an 8 groove pulley with a 72mm outside diameter and is listed with a multi-belt pulley. It is suitable where the belt drive arrangement matches that groove count and pulley size, and the listing also notes recommended additional repairs may include the V-Belt or V-Ribbed Belt if those components are worn.

Because this is a 24V, 100A alternator with internal regulation, it should be matched to the electrical system already in the machine rather than assumed to suit a different voltage setup. The alternator type is listed as excluding a vacuum pump, so buyers should confirm their original unit does not require a vacuum pump arrangement before fitting.

If you are replacing an existing Bosch alternator, compare the physical measurements as well as the electrical figures. The mount leg thickness of 85mm, distance from pulley to alternator of 20.2, and pulley outside diameter of 72mm are all useful checks when confirming whether the replacement will align with the existing belt line and brackets.

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 1986A00544 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 24V 100A. Part number 1986A00544 should be checked first. Listed voltage is 24. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 1986A00544, 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 24 and output 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BRUKS 806.2, BRUKS 806.2 2014, DOOSAN/DAEWOO DA30, DOOSAN/DAEWOO DA30 2013, DOOSAN/DAEWOO DA40, DOOSAN/DAEWOO DA40 2013. 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 compatibility using the part number 1986A00544, OEM number 0124655205, and the physical mounting and pulley details before purchase. Application lists can be helpful, but the final check should always be the actual alternator type, voltage, groove count, mount style, and measurements on the unit being replaced.
