OEX Starter Motor 12V 9TH CW Bosch Style BXS0105

The OEX Starter Motor BXS0105 is a 12V starter motor with 9 teeth, clockwise rotation, and Bosch style fitment characteristics. It is a new unit with a pad starter mount, 81mm mount centres, and an 82mm flange diameter, so the physical mounting details are as important as the electrical specification when confirming suitability.

This unit is rated at 1.4kW and weighs 3.4kg. Other key dimensions supplied for checking are a 240mm overall length, 10mm mount hole diameter, 25mm pinion diameter, and 6mm pinion at rest. Those measurements help narrow the match before installation, especially where the original starter is being replaced on a vehicle with limited clearance.

OEX positions this starter as a quality replacement for the Australian automotive aftermarket. The brand description supplied identifies OEX as Original Equipment Xchange, and the listed warranty on new units is 3 years for passenger applications or 1 year for commercial use. As with any starter motor, the part number and physical dimensions should be matched carefully to the vehicle and the existing unit.

Application and Buying Notes

Before ordering, compare the part number BXS0105 with the starter removed from the vehicle, then check the mounting layout against the listed 81mm mount centres, 82mm flange diameter, and 10mm mount hole diameter. Those dimensions are often the quickest way to confirm whether a Bosch style replacement is the correct physical match.

Also compare the electrical and drive details. This starter is 12V, rated at 1.4kW, has 9 teeth, rotates clockwise, and has a 25mm pinion diameter with 6mm pinion at rest. If any of those details differ from the original unit, it is worth pausing to confirm the application before purchase.

The fitment information supplied includes Holden, HSV, and Volvo Construction references, but the safest approach is still to verify the exact vehicle application against the part number and the removed starter. Model names alone are not enough for a correct match, particularly where the vehicle range includes multiple starter variants.

Because this is a new OEX starter motor, the warranty terms supplied are 3 years for passenger use and 1 year for commercial use. Keep the invoice and confirm the vehicle is being used within the relevant application type, as commercial and passenger warranty terms are listed differently.

The starter is listed as a dry clutch application, so it should be checked against the vehicle setup before fitting. The 240mm overall length and 3.4kg weight may also help when comparing to the original starter, especially where access is tight or the original unit has matching cast or pressed dimensions.

If you are replacing a Bosch style starter, it is best to compare the original unit side by side where possible. Small differences in mount position, pinion size, or rotation can affect fitment even when the vehicle make appears in the compatibility list.

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 BXS0105 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 BXS0105 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 BXS0105, 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 HOLDEN CALAIS, HOLDEN CALAIS 1991, HOLDEN CALAIS 1992, HOLDEN CALAIS 1993, HSV COMMODORE, HSV COMMODORE 1989. 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 BXS0105, Bosch style application details, 12V electrical specification, 9 tooth clockwise configuration, and the listed mounting dimensions against the original starter and vehicle application before ordering.
