OEX Starter Motor 12V 12T CW Bosch Style BXS0189

The OEX starter motor is a new 12V unit in Bosch style, identified as part number BXS0189. It is a 12-tooth, clockwise rotation starter motor with a 76mm flange diameter, 250mm overall length and 4.08kg weight, so the physical dimensions are clear before purchase.

This unit is listed as suitable for start stop applications, which is an important point for vehicles that cycle the engine more frequently than a conventional setup. The mounting arrangement is a 2 hole starter mount with M10x1.5/10 mount hole diameter and 123mm mount centre to centre.

The pinion diameter is 36mm and the pinion at rest measurement is 21mm. Those measurements matter when matching the starter to the vehicle application, especially where the existing unit or housing clearances need to align closely with the replacement starter.

Application and Buying Notes

Before ordering, confirm the existing starter matches the key identifiers for this unit: Bosch style, part number BXS0189, 12V, clockwise rotation and 12 teeth. Those details are the best first check because starter motors can look similar while differing in rotation, tooth count or mounting pattern.

The mounting and body measurements are just as important. This starter uses a 2 hole mount, M10x1.5/10 mount holes, 123mm centre to centre, a 76mm flange diameter and 250mm overall length. If the vehicle’s current starter differs in these measurements, the replacement may not locate correctly even if the connector and general shape appear similar.

The pinion diameter of 36mm and pinion at rest of 21mm are useful cross-checks when comparing against the removed starter. These measurements help reduce the risk of ordering by description only, particularly on Bosch style applications where small differences can change the result.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That warranty split is worth noting when the vehicle is used in a work setting, because duty cycle and operating conditions are different from private passenger use.

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 BXS0189 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.

OEX Starter Motor 12V 12Th CW Bosch Style - See Note. Part number BXS0189 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 BXS0189, 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.
