Mahle Alternator 24V 190A MG266

The Mahle Alternator MG266 is a new 24V unit rated at 190A, supplied as an each item for rotating electrical applications. It is listed with an internal regulator, twin leg alternator mount, and without a belt pulley, so it is intended for applications that match those exact mounting and drive details.

Key physical identifiers include 101mm inside mounting legs, 102.0 mounting bores distance, 211mm mount centre to centre, and 108.0 mounting points diameter. The alternator has a 22mm shaft diameter, a W connector/clamp, and a 1/2 UNC adjusting hole diameter.

This unit is identified as Mahle part number MG266 and is described as a Mahle Alternator 24V 190A. The listed warranty is one year. Because alternators vary by mount, regulator, pulley, and connector style, those details matter as much as voltage and amperage when checking suitability.

The alternator is also noted as meeting international electromagnetic compatibility requirements and being manufactured using environmentally friendly technologies and materials. That is a useful consideration where electrical reliability and equipment standards are part of the buying decision.

Application and Buying Notes

Before ordering, confirm the alternator mount and dimensions against your current unit. This Mahle MG266 is a twin leg alternator with 101mm inside mounting legs, 102.0 mounting bores distance, and 211mm mount centre to centre, so the physical layout needs to match the machine exactly.

The electrical setup also needs to align. This unit is 24V with a 190A charge current, uses an internal regulator, and has a W connector/clamp. If your machine uses a different regulator arrangement or connector style, the alternator may not be suitable even if the housing looks similar.

The pulley arrangement is another important check. This alternator is listed without a belt pulley, so the drive setup must suit that configuration. The shaft diameter is 22mm, which is a useful measurement when comparing against the existing unit or installation requirements.

Use the part number MG266 alongside the machine application details when checking suitability. The fitment references include several BUCYRUS, CATERPILLAR, HITACHI, KOMATSU, TAMROCK, and TEREX O&K applications, but the safest approach is still to verify the exact alternator currently fitted before purchase.

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 MG266 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, Inside Mounting Legs 101mm, Regulator Type Internal, Suits Unit Make Mahle, Alternator Mount Twin Leg, New / Reman. New, Pulleys without belt pulley, Mounting Bores Distance 102.0.

Additional published details for cross-checking include Packaging length 30.5, Packaging height 20.50, Product Group 2 ALTERNATORS, Part No. MG266, Brand MAHLE, Description Mahle Alternator 24V 190A, Adjusting Hole Diameter 1/2 UNC, Power Rating (Amp) 190, Shaft Diameter 22mm.

Mahle Alternator 24V 190A. Part number MG266 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 Twin Leg. 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 MG266, 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.

Compatibility note: Confirm compatibility by matching Mahle MG266, the 24V 190A rating, twin leg mounting dimensions, internal regulator, W connector/clamp, and the no-pulley configuration against your existing alternator and machine application before ordering.
