Mahle Starter Motor 12V 10 Tooth CW MS221

The Mahle MS221 is a new 12V starter motor with 10 teeth, clockwise rotation, and a 2.6kW power rating. It is listed as a starter motor with reduction gear, a 2-hole starter mount type, and a dust proof note, making the key identification points straightforward when matching it to an existing unit.

Important dimensions include 105mm mount centres, 82.5mm flange diameter, 241mm overall length, 32mm pinion diameter, 27mm pinion at rest, and 9.5mm mount hole diameter. Those measurements matter because starter motors are commonly matched by both electrical and physical configuration, not just by brand name or voltage.

This unit is a Mahle-branded starter motor, part number MS221, supplied new and covered by a one year warranty. The listed features also note resistance to 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

Before ordering, compare the part number MS221 with the unit you are replacing, then check the physical measurements against your existing starter motor. The important match points here are 12V, clockwise rotation, 10 teeth, 2-hole mounting, 105mm mount centres, and the 82.5mm flange diameter.

If you are cross-checking against a machine application, use the fitment references carefully and verify the exact model and year where shown, such as John Deere 244J 2004, 304J 2005, or 317 2005 to 2007. Where a machine family is listed without a year, it is still wise to confirm the exact build details on the vehicle before fitting.

The listed resistance to salt, fog, humidity, water, dust, mud, vibration, extreme temperatures, and aggressive liquids may suit harsher working conditions, but the core buying decision should still come back to fitment. Match the electrical specification, mounting arrangement, and overall length of 241mm before committing to purchase.

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 MS221 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.

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.

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 by checking the part number MS221, the 12V clockwise 10 tooth specification, and all mounting and dimensional details against the original starter motor and vehicle application before ordering.
