Mahle Starter Motor 12V 9T CW MS27

The MAHLE Starter Motor MS27 is a new 12V starter motor with clockwise rotation, a 9-tooth pinion, and a 2.6kW power rating. It is listed with a 2-hole starter mount type, 82mm flange diameter, 104mm centre-to-centre mounting, and a 250mm overall length, so the physical dimensions matter when checking replacement suitability.

This unit is supplied as an each item and is identified as part number MS27. Other useful dimensions include a 34mm pinion diameter, 23mm pinion at rest, 11mm mount hole diameter, 10.9 bore O1, and 26.0 flywheel depth. Those measurements are important for confirming alignment and engagement before purchase.

MAHLE lists this starter as suitable for dry clutch applications and with reduction gear transmission type. The tooth count is 9, the tooth pitch is 14.36, and the connecting angle is 35.0 degrees. Together, these details help narrow the match where the application depends on the starter drive geometry as well as the electrical specification.

The product also carries a one-year warranty and is described as offering strong resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids. It also complies with EMC standards and other international directives and standards, which is useful context for equipment operating in demanding environments.

Application and Buying Notes

When comparing this MAHLE MS27 starter to the old unit, start with the part number, then check the electrical and mounting details together. The important match points here are 12V, clockwise rotation, 9 teeth, 2-hole mounting, 104mm mount centre to centre, and the 82mm flange diameter. If any of those differ from the removed starter, do not assume the part will interchange.

For best results, compare the old starter’s mounting pattern, pinion size, tooth count, and rotation direction before ordering. The packaging dimensions, one-year warranty, and new-unit status are helpful for logistics and purchasing confidence, but they do not replace the need to confirm the installation details on the machine itself.

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 MS27 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty One Year, Mount Hole Diameter 11, Overall Length 250mm, Pinion Diameter 34mm, Rotation CW, Voltage 12, New / Reman. New, Wet / Dry Clutch Dry.

Additional published details for cross-checking include Bore O 1 10.9, Tooth Pitch 14.36, Connecting Angle [Degree] 35.0, Packaging length 31.8, Packaging height 13.50, Product Group 2 STARTER MOTORS, Part No. MS27, Brand MAHLE, Description Mahle Starter Motor 12V 9Th CW.

Mahle Starter Motor 12V 9Th CW. Part number MS27 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 MS27, 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 AMMANN ARP35/K, AMMANN ART35, ATLAS COPCO 364, ATLAS COPCO AW 240, ATLAS COPCO AW 260, ATLAS COPCO AW 300. 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.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number MS27 and the application details provided, then compare 12V, CW rotation, 9 teeth, 2-hole mounting, 104mm centre-to-centre, 82mm flange diameter, 34mm pinion diameter, and 26.0 flywheel depth against the removed unit.
