Mahle Starter Motor 24V 10T CW MS443

The MAHLE MS443 starter motor is a new 24V unit with a 10 tooth pinion, clockwise rotation, and a 4kW power rating. It is a gear reduction starter motor with a 3 hole mount, designed for applications that call for this combination of voltage, rotation, and mounting pattern.

Key identification details for this unit include part number MS443, flange diameter 89mm, mount centres 127mm, and a 39.6mm pinion diameter. The starter uses 3 mounting bores, a mount hole diameter of 11mm, and is listed with a flywheel depth of 25.0.

This MAHLE starter motor is supplied as new and carries a one year warranty. It is described as the gear reduction version of MS331 and IM598, which may be useful when cross-checking replacement options by part number and construction type.

Application and Buying Notes

Before ordering, match the part number MS443 and confirm the key physical checks: 24V system voltage, 10 tooth pinion, clockwise rotation, 3 hole mounting pattern, 127mm mount centres, and 89mm flange diameter. These details are the most useful checks when comparing against the existing starter on the vehicle or the removed unit.

The 4kW rating and gear reduction design are important because they define the starter’s construction and output. If you are replacing an older unit, the note that this is the gear reduction version of MS331 and IM598 may help with identification, but the safest match is still the actual part number and the measured mounting and pinion dimensions.

Also confirm the flywheel depth of 25.0, pinion diameter of 39.6mm, and pinion at rest measurement of 22mm before purchase. These measurements can matter where there are similar-looking starters with different nose, pinion, or engagement dimensions, even when the mounting pattern appears close.

The listed resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids is relevant for harsher operating conditions, but it does not replace a fitment check. For replacement work, verify the vehicle application, the physical dimensions, and the starter drive configuration together rather than relying on one detail alone.

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 MS443 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 10Th CW. Part number MS443 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 MS443, 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 MACK MANAGER, MACK MANAGER 1997, MACK MIDLUM, MACK MIDLUM 2001, RENAULT TRUCKS MIDLUM, RENAULT TRUCKS MIDLUM 2001. 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.

Compatibility note: Confirm compatibility using part number MS443, the 24V CW specification, the 10 tooth pinion, and the measured mounting and pinion dimensions before purchase. Vehicle applications are provided as a guide only and should be checked against the existing starter and the vehicle's requirements.
