OEX Starter Motor 12V 10 Tooth CW Bosch Style BXS0191

The OEX BXS0191 is a new 12V starter motor with clockwise rotation, 10 teeth on the pinion, and a Bosch-style fitment profile. It is listed with a 1.7kW power rating, a 76mm flange diameter, and a 2-hole starter mount, so it is important to match the physical details as well as the part number before ordering.

This unit is supplied as each and carries a 3-year passenger / 1-year commercial warranty. Key mounting and dimensional details include an M10x1.5/11 mount hole diameter, 122mm mount centre-to-centre, 238mm overall length, and 3.8kg weight. Those measurements matter when checking replacement compatibility on the vehicle.

OEX notes that this starter motor is not suitable for start-stop applications. If the vehicle uses start-stop operation, the listed replacement is BXS0189 instead. The unit is specified for Bosch applications, so confirming the original starter style and mounting pattern is the safest way to avoid a mismatch.

Application and Buying Notes

When replacing a starter motor, the safest match is the original part number and the physical layout. For this OEX unit, the main checks are 12V operation, clockwise rotation, 10 teeth, a 76mm flange diameter, and a 2-hole mount with 122mm centre-to-centre spacing. If any of those details differ from the original unit, it may not be the correct replacement.

The note against start-stop applications is important. OEX states this starter motor is not suitable for start-stop systems, and the listed alternative is BXS0189. If the vehicle is fitted with start-stop operation, confirm that requirement before ordering rather than relying on general Bosch-style similarity.

Because starter motors can look similar while using different housings or mounts, the measurement points matter. Check the M10x1.5/11 mount hole diameter, 238mm overall length, 32mm pinion diameter, and 21mm pinion at rest against the removed unit. Those values are useful when comparing the replacement on the bench or in the workshop.

The listed warranty is 3 years for passenger use and 1 year for commercial use. That gives a clear coverage reference, but it does not replace fitment checking. Match the vehicle application carefully, confirm the Bosch-style specification, and make sure the starter gearing and mounting arrangement are consistent with the original part before installation.

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 BXS0191 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.
