Mahle Alternator 24V 190A MG163

The MAHLE Alternator 24V 190A, part number MG163, is a new rotating electrical unit supplied as an each item with a one year warranty. It is a pad mount alternator with 4 mounting bores, designed around a 24V system and a 190A charge current rating.

Key physical details matter with this unit: mount centres A are 190mm, mount centre to centre is 108mm, mounting bores distance is 108.0mm, and the alternator uses a 22mm shaft diameter. The regulator type is internal, the connector / clamp is W, and the pulley is not supplied.

This alternator is listed as dust proof and bi-directional in rotation, which are important points when matching it to the original application. It is a MAHLE unit, with part number MG163 and pin code IR200, so the safest buying check is to confirm the part number and mounting dimensions against the removed alternator before ordering.

For installers and fleet buyers working with 24V charging systems, the practical details are straightforward: 190A output, internal regulator, pad mount arrangement, and no belt pulley included. That combination makes it important to compare the unit type, pulley setup, and mounting layout with the vehicle or machine already in service.

Application and Buying Notes

Before ordering, confirm the removed alternator matches the MAHLE MG163 in the details that matter most: 24V system voltage, 190A charge current, pad mount design, internal regulator, and the 22mm shaft diameter. A close visual match is not enough if the mounting bores, mount centres, or pulley arrangement differ.

This unit is supplied without a belt pulley, so check whether the application requires reusing the existing pulley or fitting a suitable alternative. The bi-directional rotation and connector / clamp W should also be matched to the original equipment specification rather than assumed.

The mounting measurements are especially useful on heavy equipment and industrial applications. Mount centres A are 190mm, the mount centre to centre measurement is 108mm, and the pivot hole diameter is 10.5 / 12.5 with adjusting hole diameter 10 / 12.5. Those figures should be compared carefully to the existing setup before installation.

The alternator is listed as dust proof and carries a one year warranty, but correct application matching still comes first. For equipment such as BOMAG, CATERPILLAR, PETERSON, and TEREX O&K applications shown here, confirm the exact model and series on the machine plate or the old unit, then compare it with part number MG163 and the listed mounting pattern.

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 MG163 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.

Mahle Alternator 24V 190A. Part number MG163 should be checked first. Listed voltage is 24. Listed output rating is 190. These details form the core reference points used by parts interpreters when confirming the correct replacement.

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

For part number MG163, 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 190 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BOMAG BM1200/30, BOMAG BM1200/30 2016, BOMAG BM1300/30, BOMAG BM1300/30 2016, CATERPILLAR 120M, CATERPILLAR 12M. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number MG163, voltage, 190A output, pad mount layout, 4 mounting bores, and the listed mounting dimensions against the original alternator and machine application before purchase.
