Mahle Starter Motor 12V 10 Tooth CW MS101

The Mahle MS101 starter motor is a new 12V unit with clockwise rotation, 10 teeth, and a 4.2kW power rating. It is supplied as a starter motor each and is listed with Part No. MS101, which is the key reference to confirm before ordering.

This unit is built with a 3-hole starter mount type, 126mm mount centres A, B and C, a 92mm flange diameter, and 13.5mm mounting hole diameter. The pinion diameter is 40mm, with the pinion at rest measured at 48mm, and it is specified for a dry clutch application with oiltight supplementary information.

The starter is listed as a Mahle-branded rotating electrical component and carries a one-year warranty. It is a 12V, reduction gear type starter, so matching the electrical system and the mounting layout matters just as much as matching the part number.

For buyers replacing an existing starter, the most useful checks are the 10-tooth pinion count, clockwise rotation, 3-hole mounting pattern, 126mm mount centres, and the MS101 part number. Those details help distinguish it from other similar-looking starters that may not interchange correctly.

Application and Buying Notes

Before ordering, compare the MS101 part number against the old starter or any parts catalogue reference already on the machine. The key matching points on this unit are 12V, clockwise rotation, 10 teeth, 3 mounting bores, and 126mm mount centres A, B and C.

The mounting layout is important on this starter. It uses a 92mm flange diameter, 13.5mm mounting hole diameter, and a 146.0 mounting points diameter, so the physical fit should be checked against the removed unit rather than relying on the electrical rating alone.

The unit is specified as a new 4.2kW starter with reduction gear and dry clutch application details. If your machine requires a different rotation, tooth count, clutch type, or mounting pattern, this starter should not be assumed to suit without direct part number confirmation.

Where the machine has been fitted with a Mahle starter previously, the safest approach is to cross-check the existing starter label, the part number MS101, and the application details together. Even when the machine model appears in the application list, matching the exact starter configuration remains the most important step.

The oiltight and EMC-related references are useful product details, but they do not replace fitment checks. Confirm the 12V system, the 10-tooth pinion, and the 3-hole mount before installation, especially on machinery where several starter versions may have been used across production years.

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 MS101 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 10Th CW. Part number MS101 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 MS101, 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.

Compatibility note: Confirm fitment using the MS101 part number, the 12V electrical system, clockwise rotation, 10-tooth pinion, and the 3-hole mounting details. Applications are listed for reference only and should be checked against the removed starter and machine records before purchase.
