OEX Starter Motor 24V 12T CW Bosch Style BXS9033

The OEX Starter Motor BXS9033 is a 24V, 12-tooth, clockwise-rotation starter motor in Bosch style. It is listed as a new unit with a 3-hole starter mount type, 126mm mount centres, a 92mm flange diameter, and an overall length of 400mm.

This starter motor is rated at 6.6kW and has a pinion at rest of 47mm with a pinion diameter of 46mm. It is supplied as a 24 volt unit and is noted for use with Bosch-style applications, including KB Series applications where the listed dimensions and rotation are matched correctly.

Fitment information supplied with this part shows applications across selected Atlas Copco, Case, Caterpillar and Volvo equipment. Because starter motor fitment depends on matching the mounting pattern, tooth count, rotation, voltage and overall dimensions, the part number BXS9033 and the physical measurements should be checked carefully before ordering.

Application and Buying Notes

Before buying, compare the part number BXS9033 with the starter already fitted to the machine or engine. The key matching points here are 24V voltage, 12 teeth, clockwise rotation, 3-hole mounting, 126mm mount centres, 92mm flange diameter and 400mm overall length. Those measurements are the practical checks that help separate a correct replacement from a similar-looking starter.

The listed applications include Atlas Copco XAMS 355, Case W30 and W36, Caterpillar 950F, and several Volvo construction and truck applications. Even where a vehicle or machine is named, starter motors can vary by build, engine, transmission or electrical setup, so the physical dimensions and rotation must still match the original unit.

This starter is described as Bosch style and noted for KB Series use. That tells you the general style and intended application family, but it does not remove the need to confirm tooth count, pinion diameter, pinion at rest measurement and mount centres. The weight is 19.24kg, so it is also worth handling and packing the unit carefully when comparing it to the original starter.

The warranty listed is 3yr Passenger and 1yr Commercial. If the starter is being fitted to equipment used in commercial or heavy-duty service, make sure the duty cycle, mounting pattern and electrical specification are all suitable for the machine 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 BXS9033 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 24V 12Th CW Bosch Style. Part number BXS9033 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number BXS9033, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include ATLAS COPCO XAMS 355, ATLAS COPCO XAMS 355 1980, CASE W30, CASE W30 1986, CASE W36, CASE W36 1983. 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 using part number BXS9033, 24V voltage, 12-tooth CW configuration, 3-hole mount, 126mm mount centres and the supplied application details before ordering.
