Mahle Starter Motor 24V 9 Tooth CW MS191

The Mahle MS191 is a new 24V starter motor with a 9 tooth pinion and clockwise rotation. It is listed as a 4kW unit with a 3 hole starter mount type, so the mounting pattern and electrical system both need to line up with the vehicle before purchase.

Key dimensions include 127mm mount centres A, 90mm mount centres B and 90mm mount centres C, along with a 89mm flange diameter and 337mm overall length. The pinion sits 48mm at rest, the pinion diameter is 35mm, and the unit is specified with a 51.0 flywheel depth.

This starter is marked for Mahle applications and carries part number MS191. A note is supplied for the 12 volt option, which uses MS193, so the voltage must be confirmed carefully before ordering. The unit is new and supplied each, with a one year warranty.

Application and Buying Notes

The safest way to select this starter is to match the 24V system, the 9 tooth pinion, and the clockwise rotation against the existing unit or vehicle requirements. The note for the 12 volt option points to MS193, which makes voltage confirmation essential before ordering.

The mounting details are specific: 3 hole starter mount type, 127mm mount centres A, 90mm mount centres B and C, 89mm flange diameter, and 11mm mount hole diameter. If any of those measurements differ from the fitted starter, the part should be checked again before purchase.

The listed 4kW rating, 337mm overall length, 48mm pinion at rest, and 51.0 flywheel depth are useful reference points when comparing units side by side. These dimensions help confirm physical compatibility, especially where access is limited or the starter sits close to surrounding components.

This is a new Mahle starter motor supplied with a one year warranty. It is intended for dry clutch applications and is identified as a Mahle unit, so matching the application details and part number MS191 remains the best way to avoid ordering the wrong starter.

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 MS191 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.
