Mahle Starter Motor 12V 9 Tooth CCW 2KW MS252

The Mahle MS252 starter motor is a new 12V unit with 9 teeth, CCW rotation and a 2kW power rating. It is listed as a starter motor with reduction gear and a 2-hole starter mount, so the mounting style and electrical specification are both important checks before purchase.

Key dimensions include 105mm mount centres, a 76mm flange diameter, 11mm mount hole diameter, 233mm overall length, 30mm pinion diameter and a 27.5mm pinion at rest. These measurements matter when matching the starter to the engine housing, bellhousing clearance and flywheel engagement requirements.

This unit is identified as Mahle part number MS252 and is supplied new, not remanufactured. The listed flywheel depth is 30.5, and the tooth pitch is 12.35, so the application needs to line up with those dimensions as well as the 12V, 9-tooth, CCW configuration.

The starter is described as suitable for units under the Mahle make and carries a one-year warranty. The electrical and physical specifications should be checked together, especially where an engine uses a reduction gear starter or has limited installation space.

Application and Buying Notes

Before ordering, match the MS252 part number, 12V voltage, 9-tooth pinion, CCW rotation and 2-hole mount arrangement to the unit being replaced. The listed 105mm mount centres, 76mm flange diameter and 233mm overall length are practical checks for physical fit, especially where the starter sits close to surrounding castings or guards.

The starter uses a reduction gear design and has a 2kW power rating, so it should only be compared with applications that call for the same starter style and output. The 30.5 flywheel depth, 30mm pinion diameter and 27.5mm pinion at rest are important because they affect how the starter engages with the flywheel ring gear.

If you are replacing a starter on equipment linked to Ammann, Lombardini or Ruggerini applications, use the exact application details rather than relying on the brand name alone. The fitment references include Ammann ARR 1585, Ammann RW1805, Lombardini LDW1503 and Ruggerini RF81, with year references shown for some listings.

The one-year warranty applies to the supplied new unit, but it does not replace the need to confirm electrical and physical compatibility. Check the mount hole diameter of 11mm, the mounting points diameter of 105.0 and the tooth pitch of 12.35 before fitting, particularly where the original starter has worn or damaged mounting features.

For best results, compare the old starter side by side with this Mahle MS252 unit and verify every critical measurement. On starters, a small difference in rotation, tooth count or flange dimensions can prevent installation or cause incorrect engagement with the flywheel.

If you are unsure, provide the part number MS252 and the listed application details to your parts supplier or technician. That is the safest way to confirm the correct starter before the unit is installed on the machine or engine.

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 MS252 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 CCW. Part number MS252 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 MS252, 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.

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 part number MS252, the 12V 9-tooth CCW specification, and the mounting and dimensional details before purchase. Application references are provided for guidance only and should be checked against the exact engine or machine build.
