Mahle Starter Motor 12V 9 Tooth CW MS18

The MAHLE MS18 starter motor is a new 12V unit with 9 teeth and clockwise rotation. It is listed as a starter motor with a 3.2kW power rating, a 3-hole starter mount type, and a reduction gear transmission setup, so it is intended for applications that match those physical and electrical details.

Key dimensions include 127mm mount centres A, 90mm mount centres B, 90mm mount centres C, an overall length of 287mm, a flange diameter of 89mm, and a pinion at rest measurement of 48mm. The mounting points diameter is listed as 127.0, and the mount hole diameter is 11mm, so checking the existing unit against these figures is important before ordering.

This part is identified as MAHLE part number MS18 and OEM number 11132153. It is described as original equipment part and is supplied new, with a one year warranty. The listed unit of measure is each, and the product group is rotating electrical.

Application and Buying Notes

When comparing this starter motor to the unit already on the machine, the most important checks are the 12V rating, 9 tooth pinion, clockwise rotation and the 3-hole mounting pattern. The listed mount centres of 127mm, 90mm and 90mm, plus the 89mm flange diameter and 287mm overall length, give you the quickest physical match points.

The reduction gear transmission and 3.2kW power rating are useful identifiers, but they should be matched with the existing application rather than treated as a universal replacement. Starters can look similar while differing in mount spacing, pinion rest position, or electrical specification, so the part number MS18 and OEM number 11132153 are the safest references to compare.

If you are replacing a worn or non-original starter, check the number of mounting bores, mount hole diameter of 11mm, and pinion at rest measurement of 48mm against the old unit. These details matter just as much as the voltage when confirming fitment on CASE and INTERNATIONAL HARVESTER applications.

The unit is listed as new and covered by a one year warranty. As with any starter motor purchase, it is wise to verify the machine model, year where applicable, and any existing cross-reference information before fitting, especially if the current starter has been changed previously.

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 MS18 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.

Additional published details for cross-checking include OEM Number 11132153, Bore O 1 10.9, Tooth Pitch 14.36, Mounting points diameter 127.0, Packaging width 21.50, Net Weight 8764, Product Group 1 ROTATING ELECTRICAL, Part No. MS18, Brand MAHLE, Description Mahle Starter Motor 12V 9Th CW.

Mahle Starter Motor 12V 9Th CW. Part number MS18 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 MS18, 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 321, CASE 321 1986, CASE 321 1987, CASE 321 1988, INTERNATIONAL HARVESTER 564, INTERNATIONAL HARVESTER 564 1972. 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 fitment by matching the MS18 part number, OEM number 11132153, 12V specification, 9 tooth clockwise rotation, 3-hole mount pattern and the listed dimensions against the existing starter and application details before ordering.
