Mahle Alternator 24V 100A MG811

The MAHLE Alternator MG811 is a new 24V, 100A unit with an internal regulator and a twin leg alternator mount. It is listed with an 8 groove V-ribbed belt pulley, clockwise rotation, and a 55mm pulley outside diameter, so it suits applications that match those physical and electrical details.

Key mounting measurements on this alternator include 81mm inside mounting legs, 81.5mm mounting bore distance, 139mm mount centre to centre, a 10.5mm pivot hole diameter, and an 11mm adjusting hole diameter. The alternator also has a 37.5mm distance from the pulley to the alternator body and an 85 degree connecting angle.

Electrical specification is 24 volts with 100 amps charge current. The unit is a multi-function alternator, supplied new, and covered by a one year warranty. Part number MG811, OEM number 11209618, and pin code IR98 are all listed identifiers that can help confirm the correct replacement before ordering.

Application and Buying Notes

Before ordering, compare the part number MG811 and OEM number 11209618 against the alternator currently fitted to the vehicle. The listed 24V system voltage and 100A output need to match the vehicle’s electrical requirement, and the twin leg mount with 81mm inside mounting legs is a critical physical check.

The pulley detail is also important. This unit has an 8 groove V-ribbed belt pulley with a 55mm outside diameter and clockwise rotation, so the belt arrangement and rotation direction must suit the existing application. If the pulley style, groove count, or rotation differ, the alternator may not be a direct swap.

Mounting dimensions matter just as much as electrical output. Check the 10.5mm pivot hole, 11mm adjusting hole, 81.5mm mounting bore distance, and 139mm mount centre to centre against the original unit. These measurements are the best guide when you are confirming whether the alternator will physically align in the bracketry.

The unit is described as new and carries a one year warranty, which may be important when choosing between repair and replacement. If the vehicle uses an internal regulator, that detail should also be matched carefully, as regulator type is part of the alternator specification and not something to assume.

For DAF applications, the fitment references supplied point to LF 45 and LF 55 variants, including 2001, 2006 and 2009 references. Even where the vehicle family looks similar, alternators can differ by pulley, mount, or electrical setup, so model family alone should not be used as the only check.

If you are replacing an alternator for charging issues, confirm the existing unit’s casing shape, pulley alignment, and connector arrangement before purchase. The pin code IR98 and the listed product details provide useful cross-checks, but the safest approach is still to verify the physical part against the one removed from the vehicle.

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 MG811 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 100A. Part number MG811 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 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 MG811, 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.

Compatibility note: Confirm compatibility using part number MG811, OEM number 11209618, voltage, amperage, mounting measurements, pulley details, and the listed application references before purchasing.
