Mahle Starter Motor 24V 10T CW MS428

The MAHLE starter motor MS428 is a new 24V unit with clockwise rotation, a 3.0kW power rating, and a 10-tooth pinion. It is listed as an original equipment part and is supplied as a single starter motor each.

Key physical details include a 240mm overall length, 82.5mm flange diameter, 32mm pinion diameter, 10.5mm mount hole diameter, and a 2-hole starter mount type. The unit also has a 105mm centre-to-centre mount spacing and a 45.0 degree connecting angle.

This starter is specified as a reduced-gear transmission type with 2 mounting bores, 12.29 tooth pitch, and 30.0mm flywheel depth. If you are replacing a starter by part number, MS428 is the main identifier to check against the existing unit.

Application and Buying Notes

Before ordering, confirm the replacement starter matches MS428, 24V, clockwise rotation, and the 10-tooth pinion layout. These are the most important checks when matching a starter motor, especially where the existing unit has been identified by part number.

The mounting details should also be compared carefully: 2-hole mount type, 2 mounting bores, 105mm centre-to-centre spacing, 10.5mm mount hole diameter, and a 45.0 degree connecting angle. If any of those measurements differ from the original unit, the starter may not align correctly.

The listed flywheel depth of 30.0mm, pinion diameter of 32mm, and overall length of 240mm are useful checks for physical clearance and engagement. These dimensions help confirm that the starter matches the vehicle’s installation requirements, not just the electrical rating.

Because fitment can vary by machine build and application, it is best to verify the exact part number and compare the old starter against the listed dimensions before purchase. The product is marked as an Original Equipment part and carries a one-year warranty, but correct application still depends on matching the starter to the vehicle or machine specification.

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 MS428 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 MS428 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 MS428, 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 JOHN DEERE 244J, JOHN DEERE 244J 2004, JOHN DEERE 304J, JOHN DEERE 304J 2005. 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 fitment by checking part number MS428, 24V specification, clockwise rotation, 10-tooth pinion, and the mounting and dimensional details before ordering. Use the listed application information only where it matches the vehicle or machine exactly.
