Application and Buying Notes

When comparing starters, the safest checks are the part number BXS4022, the Bosch style application, and the physical dimensions. This unit is 12V, 1.1kW, clockwise rotation, and has a 21 tooth pinion, so the replacement needs to match the vehicle’s electrical setup and starter engagement requirements.

The mounting details matter just as much as the electrical rating. Confirm the 3 hole starter mount, 118mm mount centres A, 75mm mount centres B, 84mm mount centres C, and the M10x1.5 / 11 mount hole diameter. The 72mm flange diameter, 48mm nose cone length, and 210mm overall length are also useful checks where space and housing alignment are tight.

If you are replacing an existing starter, compare the old unit’s tag and mounting pattern carefully before ordering. A Bosch style starter can vary in physical layout between applications, so matching the pinion count, rotation, and measurements is important even when the vehicle family looks similar on paper.

The warranty listed is 3 years for passenger use and 1 year for commercial use. That warranty does not replace fitment checking, so it is still best practice to verify the application details against the existing starter and vehicle build before installation.

This starter is listed as a new unit and weighs 3.4kg, which can help when comparing against a removed part. If the old starter has different mount centres, a different flange diameter, or a different tooth count, it should not be assumed to be interchangeable without checking the full specification set.

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 BXS4022 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 21Th CW Bosch Style. Part number BXS4022 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 BXS4022, 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.

Compatibility note: Confirm fitment by checking the part number BXS4022, the Bosch style application, the 12V 21 tooth CW configuration, and all mounting dimensions against the removed starter and vehicle requirements before purchase.
