OEX Starter Motor 12V 9 Tooth CW Bosch Style BXS4019

The OEX starter motor BXS4019 is a new 12V unit with 9 teeth, clockwise rotation, and a Bosch-style application. It is listed as a 2.0kW starter motor with a 2-hole starter mount, which makes the physical dimensions and mounting pattern important when matching it to the vehicle or equipment.

Key dimensions include 111mm mount centres, a 74mm flange diameter, 56mm nose cone length, and an overall length of 238mm. The pinion diameter is 29mm, the pinion at rest measures 19mm, and the unit weighs 3.8kg. These measurements are useful when comparing against the original starter before ordering.

This unit is identified as part number BXS4019 and is suited to Bosch units. It is supplied as a new starter motor and is listed for dry clutch applications. The warranty is 3 years for passenger use and 1 year for commercial use, so it is important to confirm the application and duty cycle before purchase.

Application and Buying Notes

Before buying, compare the part number BXS4019, the Bosch-style application, and the physical measurements against the original starter. The key checkpoints here are 12V, clockwise rotation, 9 teeth, 2-hole mounting, 111mm mount centres, and the 74mm flange diameter. Matching these points reduces the chance of ordering the wrong unit.

The starter’s 2.0kW rating gives a clear indication of the electrical output class, but it should still be matched to the vehicle or machine specification rather than assumed to be interchangeable with any Bosch-style starter. The pinion diameter of 29mm, the 56mm nose cone length, and the 238mm overall length are practical comparison points when checking for physical clearance and alignment.

This is a new starter motor and is listed for dry clutch applications. If the original starter has different mounting points, a different tooth count, or a different rotation direction, it should not be treated as a direct substitute. The supplied fitment references cover a range of industrial and machinery applications, so confirmation against the exact model and build details is still necessary.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. For commercial equipment, it is sensible to confirm the machine’s duty cycle, mounting arrangement, and Bosch compatibility before fitting. If there is any doubt, compare the removed unit side by side with the listed dimensions and part number before proceeding with the purchase.

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 BXS4019 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.

Additional published details for cross-checking include Weight 3.8kg, Product Group 1 ROTATING ELECTRICAL, Part No. BXS4019, Brand OEX, Description OEX Starter Motor 12V 9Th CW Bosch Style, Flange Diameter 74mm, Mount Hole Diameter 11, Number of Teeth 9, Pinion at Rest 19mm, Power Rating 2.0kW.

OEX Starter Motor 12V 9Th CW Bosch Style. Part number BXS4019 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 BXS4019, 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 ASV PT-30, ASV PT-50, ASV PT-60, ASV RC-50, ATLAS COPCO XAS185, ATLAS COPCO XAS185 2009. 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 by matching part number BXS4019, Bosch-style application details, 12V, 9 teeth, clockwise rotation, and the listed mounting and dimensional measurements to the original unit before ordering.
