Application and Buying Notes

Before ordering, match the part number BXS9004 and check the key dimensions: 12V, 9 tooth, CW rotation, 315mm overall length, 89mm flange diameter, and 3 hole mount with 11mm holes. These details matter because a Bosch style starter can still vary in mounting and nose dimensions from one application to another.

The listed note identifies a JF Series, passenger side mount configuration, and the unit is for dry clutch use. Those points should be checked against the vehicle’s starter location and original unit layout, especially where the application list includes multiple machine brands and model families.

The 3.0kW power rating and 8.08kg weight give a useful comparison point if you are replacing an existing starter. If the old unit is still available, compare the pinion diameter of 34mm and pinion at rest of 28mm as part of the physical verification process.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That does not replace fitment checking, so confirm the vehicle application, the starter mount type, and the Bosch unit match before fitting or energising the system.

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 BXS9004 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 BXS9004 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 BXS9004, 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 AGCO ALLIS 9630, AGCO ALLIS 9650, AGCO ALLIS R50 GLEANER, AGCO ALLIS R52 GLEANER, ATLAS COPCO AS81, ATLAS COPCO ST35. 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 matching part number BXS9004, Bosch style application details, 12V CW configuration, and the stated mounting measurements against the vehicle’s original starter before purchase.
