Application and Buying Notes

The key checks for this starter motor are the 12V system, 9-tooth pinion, clockwise rotation, Bosch-style application, and the physical mounting dimensions. Before ordering, compare the 116mm and 82mm mount centres, the 66mm flange diameter, the 3-hole mount type, and the 211mm overall length against the unit being removed.

The part number BXS4013 is the safest reference point when matching a starter motor, especially where vehicle descriptions can vary by market, engine, or build date. If the original starter shows a Bosch-style unit, confirm the tooth count, pinion diameter of 29mm, and pinion at rest measurement of 12mm as part of the identification process.

This starter is listed as new, not remanufactured, and carries a 3 year passenger or 1 year commercial warranty. That distinction matters because warranty coverage differs by use case, so the intended application should be clear before the part is fitted to a passenger vehicle or commercial vehicle.

Because starter motors are dimension-sensitive components, it is worth checking the mount hole diameter of 9mm, the flange diameter, and the existing cable and housing arrangement on the vehicle before purchase. A close match in appearance is not enough on its own if the mounting pattern or pinion specification is different.

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 BXS4013 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.

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.
