Mahle Starter Motor 12V 9 Tooth CW MS404

The MAHLE Starter Motor MS404 is a 12V starter motor with a 9 tooth pinion, clockwise rotation, and a 2kW power rating. It is listed as a new unit, supplied each, and uses a 2 hole starter mount type with 2 mounting bores and 105mm mount centres.

Key physical checks include a 30mm pinion diameter, 21mm pinion at rest, 82mm flange diameter, and 10mm mount hole diameter. The unit is described as suitable for a dry clutch application and for a transmission type with reduction gear.

This starter is identified with part number MS404 and brand MAHLE. Where a replacement starter is being matched, the most important checks are voltage, tooth count, rotation, mount pattern, flange size, and flywheel depth, which is listed at 24.0.

The unit is covered by a one year warranty and is described within the rotating electrical product group. For workshop or trade buying, those core identifiers help confirm whether the starter on hand matches the vehicle application before installation begins.

Application and Buying Notes

Before ordering, match the part number MS404 and confirm the starter details against the original unit or vehicle application. The critical checks here are 12V, 9 tooth, clockwise rotation, 2 hole mounting, and 105mm mount centres, because those are the details that usually determine whether the starter will physically and electrically suit the job.

The flange diameter is 82mm and the mount hole diameter is 10mm, so the mounting face should be checked carefully against the vehicle side and any removed starter. The listed pinion diameter is 30mm with a pinion at rest measurement of 21mm, and the flywheel depth is 24.0, which are useful measurements when comparing replacement starters that look similar but are not interchangeable.

This starter is described as a dry clutch unit for a transmission with reduction gear, so it should be matched to the correct application rather than chosen on tooth count alone. Even when the external shape looks close, differences in mount centres, rotation, pinion position, or flywheel depth can prevent correct engagement.

The unit is new and carries a one year warranty, but that does not replace the need to confirm compatibility before fitting. As with any starter motor, the safest approach is to compare the old part, the vehicle application details, and the listed dimensions together, especially where the vehicle has had previous repairs or non-standard components fitted.

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 MS404 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 CW. Part number MS404 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 MS404, 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.

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.

Compatibility note: Confirm fitment by checking part number MS404, 12V specification, 9 tooth clockwise configuration, 2 hole mount pattern, 105mm mount centres, and the listed flange, pinion, and flywheel depth measurements against the vehicle and the removed starter motor.
