Mahle Starter Motor 24V 11 Tooth CW New - Part No. MS439

Mahle starter motor, part number MS439, designed for 24V applications with 11 teeth and clockwise rotation. It is listed as a new unit, not remanufactured, and suits a dry clutch setup with reduction gear transmission. For buyers matching by core specifications, the key identifiers are the 24 volt rating, 11-tooth pinion, CW rotation, and 4kW power rating.

Physical dimensions are important on starter motors, and this unit has several verified mounting and housing measurements: 3-hole starter mount type, 127mm mount centres A, 94mm mount centres C, 82mm mount centres B, 89mm flange diameter, and 11mm mounting hole diameter. The pinion measures 41mm diameter, the pinion at rest is 28mm, and the tooth pitch is 14.39, so checking these details against the existing starter is sensible before ordering.

The product is identified as a Mahle starter motor in the rotating electrical group, supplied as each, with one year warranty. It also carries listed resistance characteristics for salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids, along with compliance to EMC and other international directives and standards.

Application and Buying Notes

When replacing a starter motor, matching the part number and the physical layout matters just as much as the vehicle model. This Mahle unit is MS439, 24V, clockwise rotation, 11 teeth, and a 3-hole mount, so compare those details with the removed starter before committing to purchase. If the existing unit differs in rotation, tooth count, mount centres, or pinion size, it is not a direct like-for-like match.

The listed mounting measurements give useful checkpoints for compatibility. Verify the 127mm mount centres A, 94mm mount centres C, 82mm mount centres B, 89mm flange diameter, and 11mm mounting hole diameter against the original starter or service information. The reduction gear transmission and dry clutch designation are also worth confirming where the application is sensitive to starter design.

For electrical matching, the 24V rating and 4kW output are the main figures to check. A 24V starter should not be treated as interchangeable with a 12V unit, and the power rating can help distinguish between otherwise similar starters. The 11-tooth pinion, 41mm pinion diameter, and 14.39 tooth pitch are also practical points to verify if you are matching by sample rather than by vehicle listing.

This starter is supplied new and carries a one year warranty. It is listed with resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids, but those qualities do not replace fitment checking. The safest approach is to match the part number MS439 and confirm the mounting and electrical details before installation.

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 MS439 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 MS439 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 MS439, 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.

Available application references include FENDT FAVORIT, FENDT FAVORIT 1993, FENDT FAVORIT 1994, FENDT FAVORIT 1995, MAN 10.180, MAN 10.180 1993. 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 with the part number MS439, the 24V electrical rating, 11-tooth clockwise configuration, and the recorded mount centres and flange dimensions before ordering.
