Mahle Starter Motor 12V 9 Tooth CW MS12

The Mahle MS12 starter motor is a new 12V unit with 9 teeth and clockwise rotation, designed as a reduction gear starter motor for applications that require a 3 hole starter mount. Key dimensions include 146mm mount centres A, 103mm mount centres C, a 92mm flange diameter, and a 270mm overall length.

This starter motor is listed with a 2.2kW power rating, a 36mm pinion diameter, a 20mm pinion at rest, and a 24.0mm flywheel depth. It is supplied as a new unit and carries a one year warranty, which gives buyers a clear reference point when matching the electrical and physical requirements of the vehicle.

The part number is MS12, and the unit is identified as an original equipment part. That makes the part number and the listed measurements especially important when comparing against the vehicle’s existing starter, because the mounting pattern, pinion count, rotation, and flywheel depth all need to align before purchase.

Application and Buying Notes

Before ordering, compare the MS12 part number, 12V voltage, 9 tooth pinion, and clockwise rotation with the starter already fitted to the vehicle. The most useful matching points are the 3 hole starter mount, 146mm mount centres A, 103mm mount centres C, and the 92mm flange diameter, because these are the details that confirm the unit will bolt up correctly.

The listed flywheel depth is 24.0, so it is important to check that measurement against the application before fitting. The pinion diameter is 36mm and the pinion at rest is 20mm, which are practical checks when comparing with a removed starter or a known replacement specification.

This starter is a reduction gear type with a 2.2kW power rating, so it should only be matched where that style and output are required. As with any starter motor purchase, confirm the vehicle’s wiring, mounting position, and mechanical clearance as well as the part number, because the wrong combination of rotation, tooth count, or mount pattern can prevent correct installation.

If you are replacing an existing unit, the safest approach is to compare the old starter side by side with the MS12 and verify the mount centres, overall length of 270mm, and the 12V electrical specification. That extra check is worthwhile on vehicles with multiple starter variants across different years or configurations.

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 MS12 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 MS12 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 MS12, 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.

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: Please confirm compatibility using the MS12 part number, the 12V 9 tooth CW specification, and the listed mounting and flywheel dimensions before purchase. Fitment should always be checked against the vehicle application and the existing starter motor.
