Mahle Alternator 12V 270A MG755

The MAHLE Alternator MG755 is a new 12V unit rated at 270A, supplied as an alternator only with no belt pulley fitted. It carries an internal regulator and is listed under series AAT/T1, which makes the key ordering checks straightforward: 12V system, 270 amp output, part number MG755, and Pin Code IR165.

This unit is built with a twin leg alternator mount, two mounting bores, and a mounting bores distance of 102.0 mm. The mount hole diameter is 12.7 mm, the inside mounting legs measure 102 mm, and the mounting points diameter is 108.0 mm. Those dimensions matter when you are comparing it to the alternator already in the vehicle or matching it to an existing application by measurement.

As listed, the alternator is new rather than remanufactured and is supplied by MAHLE for the rotating electrical category. The unit weight is 13,480 g, packaging length is 30.5, packaging width is 23.00, and packaging height is 20.50, so it is a substantial component and should be handled carefully during inspection and installation.

Application and Buying Notes

Before ordering, confirm the vehicle uses a 12V charging system and compare the alternator already fitted with the listed MG755 details. The important match points here are the 270A output, internal regulator, twin leg mount, 102.0 mm mounting bores distance, and 12.7 mm mount hole diameter. If any of those points differ, the alternator should be checked against the original unit before purchase.

Because this alternator is supplied without a belt pulley, it is important to confirm whether your application requires the existing pulley to be transferred across or whether the vehicle set-up allows an alternator without one. The shaft diameter is 22 mm and the pulley section is listed as not applicable, so pulley arrangement should be treated as a practical fitting checkpoint rather than assumed.

The part number MG755 and Pin Code IR165 are the clearest identifiers for cross-checking. If you are matching by part number, compare those identifiers along with the MAHLE brand, AAT/T1 series, and the physical dimensions. That approach is more reliable than relying on description wording alone, especially where alternator housings can look similar but use different mounts or regulator arrangements.

This unit is listed as new and carries a one year warranty. It is a heavy rotating electrical component at 13,480 g, so careful handling is sensible during unpacking and installation. Check the condition of mounting faces, connectors, and any transferred components before fitment so the alternator can be installed without avoidable delays.

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 MG755 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, Mount Hole Diameter 12.7, Power Rating (Amp) 270, Regulator Type Internal, Shaft Diameter 22mm, Voltage 12, New / Reman. New, Pulleys without belt pulley.

Additional published details for cross-checking include Mounting Bores Distance 102.0, Packaging length 30.5, Packaging height 20.50, Product Group 2 ALTERNATORS, Part No. MG755, Brand MAHLE, Description Mahle Alternator 12V 270A, Inside Mounting Legs 102mm, Pin Code IR165.

Mahle Alternator 12V 270A. Part number MG755 should be checked first. Listed voltage is 12. Listed output rating is 270. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG755, 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 270 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm compatibility by matching the part number MG755 and Pin Code IR165 with the vehicle application, then verify the 12V system, 270A rating, internal regulator, twin leg mount, and listed mounting dimensions before ordering.
