Mahle Starter Motor 12V 9 Tooth CW MS193

The Mahle starter motor MS193 is a new 12V unit with clockwise rotation, 9 teeth, and a 3kW power rating. It is listed as a 3-hole starter with a flange diameter of 89mm, overall length of 337mm, and mounting points designed around 127mm and 90mm centres.

This starter motor suits Mahle applications and is supplied as a new unit, not remanufactured. Key dimensions include a pinion diameter of 35mm, pinion at rest of 48mm, mount hole diameter of 11mm, and a flywheel depth of 51.0, which are all important when confirming interchange.

The part number is MS193 and the note supplied with the unit states that for the 24V option you should use MS191. That makes voltage confirmation essential before ordering, especially where the existing starter is similar in appearance but differs in electrical specification or mounting details.

Application and Buying Notes

Before ordering, match the part number MS193 and confirm the electrical setup is 12V with clockwise rotation. The note supplied with the unit also flags MS191 as the 24V option, so the starter voltage must be checked against the vehicle or machine before purchase.

The mounting layout is a key check on this starter motor. It is a 3-hole unit with 127mm and 90mm mount centres, an 11mm mount hole diameter, and an 89mm flange diameter, so the replacement needs to align with the existing mounting pattern and clearances.

The pinion and flywheel details matter just as much as the electrical specification. This unit has 9 teeth, a 35mm pinion diameter, a 48mm pinion at rest, and a flywheel depth of 51.0, so those values should be compared with the removed starter or the application details already on hand.

The listed applications include CASE, INTERNATIONAL HARVESTER, MERCEDES-BENZ, and NEW HOLLAND entries, but the safest way to confirm compatibility is by matching the exact application details and measurements as well as the starter part number. A starter can look similar across models while differing in voltage, rotation, mount centres, or pinion configuration.

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 MS193 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 MS193 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 MS193, 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.

Available application references include CASE 431, CASE 431 1986, CASE 533/A, CASE 533/A 1986, INTERNATIONAL HARVESTER 321, INTERNATIONAL HARVESTER 321 1986. 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: Confirm compatibility using the MS193 part number, 12V clockwise specification, 3-hole mounting pattern, and the measured dimensions before ordering. Where the existing starter differs in voltage, rotation, mount centres, or pinion details, do not rely on appearance alone.
