Mahle Starter Motor 12V 13 Tooth CW MS129

The Mahle starter motor listed here is a 12V unit with 13 teeth, clockwise rotation, and a 2.3kW power rating. It is identified as part number MS129 and OEM number 11139410, which gives you two useful reference points when matching a replacement starter for the correct application.

It is a new starter motor, supplied as an original equipment part, and it uses a 3 hole starter mount type. The important physical checkpoints are the 144mm mount centres A, 117mm mount centres B, 78mm mount centres C, 92mm flange diameter, and 11mm mount hole diameter.

Other useful measurements include a 20mm pinion at rest, 44mm pinion diameter, 252mm overall length, and 23.0 flywheel depth. Those figures matter because starter fitment depends on more than voltage alone, especially where mounting pattern, pinion position, and flywheel engagement must line up correctly.

If you are replacing an existing starter, the safest approach is to compare the part number, OEM number, mount pattern, rotation, tooth count, and dimensions before ordering. This Mahle unit is described as a starter motor for a 12V system with reduction gear transmission type, so it is important to match the application carefully rather than relying on appearance alone.

Application and Buying Notes

When comparing this starter to the unit being removed, begin with the part number MS129 and OEM number 11139410. Those identifiers are the most reliable starting points, then check the 12V rating, 13 tooth pinion, clockwise rotation, and 3 hole mounting pattern to make sure the replacement matches your application.

The physical dimensions are just as important as the electrical details. Mount centres A 144mm, B 117mm, and C 78mm, together with the 92mm flange diameter and 11mm mount hole diameter, help confirm the starter will bolt up correctly. If any of those dimensions differ from your original part, stop and verify before purchase.

Flywheel engagement should also be checked carefully. The listed pinion at rest is 20mm, pinion diameter is 44mm, and the flywheel depth is 23.0. These measurements affect how the starter sits and engages, so they should be compared against the existing unit or the vehicle application details already known to you.

This starter is described as new and as an original equipment part, which may suit buyers wanting a direct replacement rather than a rebuilt unit. It also carries a one year warranty. As with any starter motor, correct identification is best confirmed before fitting, since wrong rotation, tooth count, or mount pattern can prevent proper installation.

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 MS129 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 13Th CW. Part number MS129 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 MS129, 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.

Compatibility note: Please confirm compatibility using part number MS129, OEM number 11139410, and the listed measurements and application details before ordering. If you are unsure, compare the removed starter against the 12V, 13 tooth, CW, 3 hole specification set.
