Mahle Starter Motor 12V 9 Tooth CW MS432

The Mahle starter motor MS432 is a new 12V unit with a clockwise rotation and 9 teeth, designed as a 2.0kW starter motor for equipment that matches the listed mounting and engagement dimensions. Key identifiers include part number MS432, 2-hole starter mount type, 102mm mount centres, and an overall length of 242mm.

This starter motor is listed with a 12.5mm mount hole diameter, 82.5mm flange diameter, 30mm pinion diameter, 40.7mm pinion at rest, and a 43.7 flywheel depth. Those measurements matter because starter fit depends on physical alignment as well as voltage, rotation, tooth count, and mounting pattern.

Mahle has specified this unit as suitable for applications requiring a 12V, clockwise starter motor with 9 teeth and a dry clutch setup. It is supplied new, with a one year warranty, and is listed under Mahle as the unit make and brand reference.

Application and Buying Notes

Before ordering, compare the part number MS432 with the original starter and check the electrical and physical details together. This unit is 12V, CW rotation, 9 tooth, and 2.0kW, so a match on one detail alone is not enough if the mounting pattern or engagement depth differs.

The mounting details are especially important on starter motors. This Mahle unit has 2 mounting bores, 102mm mount centres, a 12.5mm mount hole diameter, an 82.5mm flange diameter, and a 242mm overall length. If any of those measurements differ from the machine currently fitted, the starter may not align correctly.

Engagement dimensions also need to be checked carefully. The listed pinion at rest is 40.7mm, the pinion diameter is 30mm, the tooth pitch is 12.35, and the flywheel depth is 43.7. Those figures help confirm whether the starter meshes correctly with the flywheel in the intended application.

The fitment groups include AMMANN, ATLAS COPCO, BOMAG, DYNAPAC, HATZ, HUSQVARNA CONSTRUCTION and WACKER NEUSON applications, but model and year information should still be checked against the machine plate or existing unit. Starter motors can look similar across different equipment while still having different mount centres, rotation, or pinion geometry.

This is a new part and is listed with a one year warranty. That gives a clear purchasing reference, but it does not replace a direct check of the application details, especially when the machine is used in demanding conditions or has had previous repairs, alternations, or replacement components installed.

If you are comparing against an old starter, use the original part number, tooth count, rotation direction, and mount type first, then confirm the measured dimensions. A correct electrical rating with the wrong physical fit will still create installation issues, so it is worth checking the full set of listed measurements before purchase.

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 MS432 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 Bore O 1 12.5, Tooth Pitch 12.35, Connecting Angle [Degree] 38.0, Packaging length 25.0, Packaging height 13.60, Product Group 2 STARTER MOTORS, Part No. MS432, Brand MAHLE, Description Mahle Starter Motor 12V 9Th CW.

Mahle Starter Motor 12V 9Th CW. Part number MS432 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 MS432, 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 APH100-20, AMMANN APH100-20 2015, AMMANN APH1000TC, AMMANN APH1000TC 2015, ATLAS COPCO LG504, ATLAS COPCO LG504 1997. 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: Please confirm fitment by matching part number MS432 and checking voltage, rotation, tooth count, mount type, mount centres, and engagement dimensions against your existing starter or machine application.
