Mahle Starter Motor 24V 11T CW MS203

The Mahle starter motor listed here is a new 24V unit with 11 teeth, clockwise rotation, and part number MS203. It is also identified with OEM number 1201862, and the key physical details include a 48mm pinion at rest, 92mm flange diameter, and 3-hole starter mount.

This is a 6.5kW starter motor with reduction gear, intended for a dry clutch application. The listed construction notes include insulated ground, soft start relay, and thermo protection, which are useful points to confirm against the vehicle’s existing starter and electrical setup before ordering.

Mounting dimensions are specific on this unit: 11mm mount hole diameter, 3 mounting bores, 146.0 mounting points diameter, and 51.0 flywheel depth. Those measurements matter because starter fitment depends on the mounting pattern, pinion position, and engagement depth as much as the voltage rating.

Mahle is the listed brand, and the unit is supplied as new with a one-year warranty. As with any starter replacement, the best result comes from matching the part number, tooth count, rotation, voltage, and mounting details before fitment.

Application and Buying Notes

Before buying, confirm the part number MS203 against the starter you are replacing and check whether the vehicle requires a 24V unit with 11 teeth and clockwise rotation. The OEM reference listed is 1201862, which is another practical checkpoint when comparing against the old starter or parts catalogue.

The mounting details are just as important as the electrical rating. This starter is listed with a 3-hole mount, 11mm mount hole diameter, 146.0 mounting points diameter, 92mm flange diameter, and 51.0 flywheel depth, so those dimensions should be compared carefully with the original unit to avoid installation issues.

The 48mm pinion at rest and 48mm pinion diameter indicate the engagement end of the starter is fixed to specific geometry. If the pinion position, tooth count, or flywheel depth do not match the original application, the starter may not engage correctly even if the bolt pattern looks similar.

The listed notes of insulated ground, soft start relay, thermo protection, and reduction gear are useful technical details, but they should be treated as application characteristics rather than a substitute for confirming fitment. If the vehicle uses a different control arrangement or starter style, it is best to verify compatibility before purchase.

This is a new Mahle starter motor and it is supplied with a one-year warranty. Keep in mind that electrical parts can be sensitive to incorrect installation or mismatched application, so the safest approach is to match the part number, the 24V specification, and the mounting measurements before fitting.

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 MS203 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 11Th CW. Part number MS203 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 MS203, 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

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 using part number MS203, OEM number 1201862, and the listed application details such as 24V, 11 teeth, CW rotation, 3-hole mounting, 92mm flange diameter, and 51.0 flywheel depth before ordering.
