Mahle Starter Motor 24V 9 Tooth CW MS1052

The Mahle starter motor MS1052 is a new 24V unit with clockwise rotation and a 9 tooth pinion. It is listed as an Original Equipment part and is supplied as a starter motor each, with a one year warranty.

Key identification details include part number MS1052, OEM number 11139229, 4.0kW power rating, and a 3 hole starter mount type. The overall length is 340mm, with a 89mm flange diameter and 48mm pinion at rest.

Mounting measurements supplied for this unit include 127mm mount centres A, 90mm mount centres B, 90mm mount centres C, and a 127mm mounting points diameter. The mount hole diameter is 11mm and the bore O 1 is 11.2mm, so matching the physical pattern matters as much as matching the voltage.

This starter is intended for applications where the listed electrical and mounting details align with the existing unit. The fitment list includes CASE, DAYSWORTH, SCANIA, and VOLVO applications, so confirming the exact engine or vehicle match before purchase is important.

Application and Buying Notes

When checking compatibility, compare the part number MS1052, the OEM number 11139229, and the key physical dimensions before ordering. The important checks here are 24V voltage, clockwise rotation, 9 tooth pinion, 4.0kW rating, and the 3 hole mount pattern with 127mm and 90mm mounting centres.

Starter motors can look similar while still differing in pinion count, rotation, flange diameter, or mounting offset. For this unit, the 89mm flange diameter, 340mm overall length, 35mm pinion diameter, and 48mm pinion at rest are useful reference points when matching to the removed starter or vehicle.

If you are replacing a starter on a CASE, DAYSWORTH, SCANIA, or VOLVO application, use the exact vehicle details and the existing starter identification rather than relying on the model name alone. The fitment list covers multiple series and years, so the safest approach is to match the listed application against the old unit and the vehicle build details.

The one year warranty applies to the supplied Mahle starter motor, but warranty coverage does not replace the need to confirm fitment. A correct electrical match and a correct mounting match are both needed for a 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 MS1052 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 24V 9Th CW. Part number MS1052 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number MS1052, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CASE 540, CASE 540 1988, DAYSWORTH PT20-SVH, DAYSWORTH PT20-SVH 1996, SCANIA 2 - SERIES, SCANIA 2 - SERIES 1985. 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 fitment using part number MS1052, OEM number 11139229, and the listed voltage, rotation, tooth count, and mounting dimensions before ordering.
