Mahle Alternator 12V 100A MG485

The Mahle Alternator MG485 is a new 12V, 100A unit supplied as each and identified with OEM number 11204326. It is built with a twin leg alternator mount, 82mm inside mounting legs, and an internal regulator, so the mounting style and charging control setup need to match the vehicle application before purchase.

This alternator uses an 8 groove, V-ribbed belt pulley with a 55mm outside diameter and clockwise rotation. It is listed as an alternator with coil control, and the pulley-to-alternator distance is 37.1, which are useful checks when comparing against the original unit already fitted.

For buyers matching electrical and physical fitment, the key identifiers are Part No. MG485, brand Mahle, voltage 12, and charge current 100A. The unit is new rather than remanufactured, and it carries a one year warranty.

The listed fitment data includes CLAAS ELIOS, HATTAT C SERIES, JOHN DEERE SERIES 5, and MCCORMICK X50 applications. Even where a family name appears in fitment data, the safest approach is to confirm the exact application against the part number, pulley layout, and mounting measurements before ordering.

Application and Buying Notes

Before ordering, compare the original alternator’s part number, mounting arrangement, and pulley configuration against MG485. The important physical checks here are the twin leg mount, 82mm inside mounting legs, 82.0 mounting bores distance, 86.0 mounting points diameter, and 8 groove pulley section, because a close visual match is not enough on its own.

The electrical specification is 12V with a 100A charge current, so it needs to suit the vehicle’s charging system and the way the existing alternator is controlled. This unit is listed as an alternator with coil control and an internal regulator, which makes the regulator type an important confirmation point during replacement.

Rotation also matters. This alternator is clockwise rotation, so it should only be used where the driven belt arrangement and original unit match that direction. The pulley is a V-ribbed belt pulley with a 55mm outside diameter, and the connecting angle is 60.0 degree, so these dimensions should be checked carefully if the existing alternator is being replaced after damage or removal.

The fitment listing covers CLAAS ELIOS, HATTAT C SERIES, JOHN DEERE SERIES 5, and MCCORMICK X50 applications, but the exact vehicle version can still vary. If you are matching by machine model, use the application detail, year where listed, and the part number together rather than relying on model family alone.

If you are unsure, remove the existing alternator and compare all visible identifiers before fitting. The most useful checks are MG485, OEM number 11204326, 12V, 100A, internal regulator, clockwise rotation, and the 8 groove pulley, because those details reduce the risk of ordering the wrong unit.

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 MG485 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 82mm, Power Rating (Amp) 100, Pulley Section 8 Groove, Rotation CW, Voltage 12, New / Reman. New, Alternator Charge Current [A] 100.

Additional published details for cross-checking include Alternator Type with coil control, Connecting Angle [Degree] 60.0, Distance from pulley to the alternator 37.1, Packaging width 18.60, Net Weight 5471, Product Group 1 ROTATING ELECTRICAL, Part No. MG485, Brand MAHLE, Description Mahle Alternator 12V 100A, Adjusting Hole Diameter 10.

Mahle Alternator 12V 100A. Part number MG485 should be checked first. Listed voltage is 12. Listed output rating is 100. 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 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MG485, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CLAAS ELIOS, CLAAS ELIOS 2012, HATTAT C SERIES, HATTAT C SERIES 2014, JOHN DEERE SERIES 5, JOHN DEERE SERIES 5 2009. 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 MG485, OEM number 11204326, and the alternator’s mounting, pulley, voltage, and rotation details before ordering.
