Application and Buying Notes

Before ordering, match the part number MS399 and compare the mounting pattern carefully. The starter is a 12V, 10 tooth, clockwise unit with 127mm mount centres, 90mm mount centres C, a 3 hole mount, and a 89mm flange diameter, so those dimensions need to line up with the original starter on the machine.

The 3.2kW rating and reduction gear transmission are important identifiers, especially where the original starter has a specific output or drive arrangement. Even small differences in pinion size, pinion at rest measurement, or mount hole diameter can prevent correct installation.

This unit is marked new and carries a one year warranty. It is sold as each, so check whether your job requires one starter motor only and confirm the electrical and mechanical spec before purchase to avoid delays on the bench or in the field.

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 MS399 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 MS399 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 MS399, 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.

Available application references include ARMATRAC SERIE-11, ARMATRAC SERIE-11 2012, BASAK 2000 SERIES, BASAK 2000 SERIES 2013, BASAK 2000 SERIES 2015, BASAK 2000 SERIES 2016. 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 part number MS399 and by matching the 12V, 10 tooth, clockwise, 3 hole, 127mm / 90mm mounting details against the existing starter and application before ordering.
