Mahle Starter Motor 12V 9 Tooth CW MS641

The MAHLE starter motor MS641 is a new 12V unit with 9 teeth and clockwise rotation, listed as an OE product. It suits a 2 hole starter mount and uses a reduction gear transmission type, which makes the key identification points straightforward when matching the part to the vehicle application.

Key physical dimensions include an overall length of 277mm, flange diameter of 82.5mm, mount centres A of 102mm, and mounting points diameter of 105.0mm. The pinion at rest is 23mm, the pinion diameter is 34mm, and the flywheel depth is listed at 26.0, so these measurements should be checked carefully against the existing starter and bellhousing space.

This starter motor is rated at 3.2kW and has 2 mounting bores, with a 11mm mount hole diameter and 10.9 bore O 1 measurement. The part number is MS641, the brand is MAHLE, and it carries a one year warranty.

Application and Buying Notes

Before ordering, confirm the part number MS641 and compare the starter layout to the vehicle already fitted. The important checks here are 12V operation, clockwise rotation, 9 teeth, and the 2 hole mount arrangement, because those details must align with the application before installation.

Measure the existing starter where possible and compare the listed dimensions: 277mm overall length, 82.5mm flange diameter, 102mm mount centres A, 105.0 mounting points diameter, and 26.0 flywheel depth. These measurements are often the difference between a correct fit and a unit that will not seat properly.

The reduction gear design and 3.2kW power rating are part of the unit specification, not a substitute for fitment checking. Confirm the mounting bores, mount hole diameter of 11mm, pinion diameter of 34mm, and pinion at rest measurement of 23mm against the original part or application details before purchase.

If you are replacing a starter, it is best to verify the existing unit’s label, tooth count, rotation, and mount style rather than relying on appearance alone. MAHLE uses the MS641 identifier for this unit, and matching that reference with the physical measurements is the safest approach when selecting the correct replacement.

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 MS641 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 Starter Motor 12V 9Th CW. Part number MS641 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number MS641, 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 starter motor in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 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 MAHLE MS641 part number, 12V rating, 9 tooth clockwise rotation, 2 hole mount, and the listed dimensions against the vehicle’s existing starter and application details before buying.
