OEX Starter Motor 12V 9 Tooth CW Bosch Style BXS0172

The OEX Starter Motor BXS0172 is a new 12V starter motor with 9 teeth, clockwise rotation, and a Bosch-style suit for units marked Bosch. It is listed with a 2.3kW power rating, a 2-hole starter mount, and a dry clutch setup, so it suits buyers who need those measured and application-specific details matched before purchase.

Key dimensions on this unit include 102mm mount centres A, 63mm nose cone length, 256mm overall length, 82.5mm flange diameter, 11mm mount hole diameter, 34.6mm pinion diameter, and 23mm pinion at rest. Those figures matter because starter fitment is determined by more than voltage alone, particularly on equipment applications where housing, mounting, and pinion location must align correctly.

This starter motor is a Bosch style OEX unit supplied new, with the brand positioned across market leading OEM and aftermarket suppliers and sourced from ISO certified factories. It carries a 3yr passenger / 1yr commercial warranty, and the unit of measure is each.

Application and Buying Notes

Before ordering, confirm the part number BXS0172, the Bosch style application, and the physical measurements of 102mm mount centres, 63mm nose cone length, and 256mm overall length. Those dimensions are the quickest way to rule out a mismatch when replacing a starter motor on heavy equipment or construction machinery.

The 12V rating, clockwise rotation, 9 tooth pinion, and 2.3kW power rating all need to suit the vehicle or machine specification. A starter motor can look similar from the outside and still be wrong if the pinion diameter of 34.6mm, pinion at rest of 23mm, or the 2-hole mount arrangement does not line up with the existing unit.

The listed fitment points to Volvo Construction L20B applications, including model years 2003, 2004, 2005, 2006, 2007, and 2010. Even where that application appears to match, it is still sensible to compare the old starter against this unit’s flange diameter of 82.5mm and mount hole diameter of 11mm before fitting.

If you are replacing an existing Bosch-style starter, the safest approach is to verify the original starter tag, count the teeth, confirm clockwise rotation, and compare all mounting dimensions. That gives a more reliable result than relying on a visual match alone, especially where similar-looking starters may differ in nose cone length or pinion position.

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 BXS0172 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 9Th CW Bosch Style. Part number BXS0172 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 BXS0172, 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 VOLVO CONSTRUCTION L20B, VOLVO CONSTRUCTION L20B 2003, VOLVO CONSTRUCTION L20B 2004, VOLVO CONSTRUCTION L20B 2005. 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 fitment by checking part number BXS0172 against the existing starter, then match the Bosch style application, 12V rating, 9 tooth count, clockwise rotation, and all mounting dimensions before ordering.
