OEX Starter Motor 12V 10 Tooth CW Bosch Style BXS0173

The OEX Starter Motor BXS0173 is a new 12V starter motor with a 10-tooth pinion, clockwise rotation, and Bosch style fitment details. It is listed with a 2.2kW power rating, a 105mm mount centres A measurement, and a 2 hole starter mount type, so it is important to compare the physical dimensions and application details carefully before ordering.

Key dimensions include an 82.5mm flange diameter, 238mm overall length, a 28mm pinion diameter, and a 26mm pinion at rest measurement. The unit weighs 3.76kg and uses an M10x1.5 mount hole diameter, which gives buyers useful reference points when checking against the existing starter motor.

OEX lists this unit as being sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, with products sourced from ISO certified factories. The stated warranty is 3yr Passenger and 1yr Commercial, which may help when selecting a replacement for a vehicle that needs a Bosch style 12V starter motor with the same tooth count and mounting layout.

Application and Buying Notes

Start with the part number BXS0173 and then compare the physical measurements on your current starter motor. The key checkpoints here are 12V, 10 teeth, clockwise rotation, 2 hole mount type, 105mm mount centres A, and the 82.5mm flange diameter. If any of those values differ from the unit already fitted to the vehicle, the starter may not be suitable.

The Bosch style and the listed suit unit make of Bosch are important, but they are not enough on their own to confirm fitment. Check the overall length of 238mm, the M10x1.5 mount hole diameter, the 28mm pinion diameter, and the 26mm pinion at rest measurement against the existing part before purchase. These dimensions help distinguish similar starters that may look alike but are not interchangeable.

This starter is listed as new and as a dry clutch unit, so the application should be matched carefully to the vehicle’s original setup. The 2.2kW rating and 3.76kg weight provide further reference points, especially where the replacement needs to match the original electrical load and physical packaging. Use the vehicle application details only as a guide, and confirm the starter specification against the old unit where possible.

Warranty terms are listed as 3yr Passenger and 1yr Commercial, so it is still wise to verify the fit before fitting. Starter motors are commonly mistaken by tooth count, rotation direction, mount pattern, and pinion dimensions, so take the time to check each of those details rather than relying on appearance alone.

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 BXS0173 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 10Th CW Bosch Style. Part number BXS0173 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 BXS0173, 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 MERCEDES-BENZ C-CLASS, MERCEDES-BENZ C-CLASS 1993, MERCEDES-BENZ C-CLASS 1994, MERCEDES-BENZ C-CLASS 1995. 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.

Compatibility note: Confirm compatibility using part number BXS0173, the Bosch style application, and the full set of physical measurements before ordering. Do not rely on appearance alone, as starter motors with similar housings can differ in tooth count, rotation, mounting, and pinion dimensions.
