OEX Starter Motor 12V 9 Tooth CW Bosch Style BXS0161

The OEX starter motor in this listing is a 12V, clockwise rotation unit with a 9 tooth pinion and Bosch style fitment profile. It is a new starter motor, sold each, with part number BXS0161 and a power rating of 1.8kW.

Key dimensions include 101mm mount centres, a 76mm flange diameter, a 56.5mm nose cone length, and an overall length of 244mm. The starter uses a 2 hole mount and M10x1.5 mount hole diameter, so those dimensions should be checked carefully against the vehicle application before ordering.

This unit has a 29mm pinion diameter and 20.5mm pinion at rest, with a dry clutch arrangement and a weight of 3.52kg. It is listed as suitable for Bosch units, which makes the matching of the existing starter specification and mounting layout especially important when comparing options.

Application and Buying Notes

Before ordering, compare the part number BXS0161 with the original starter and check the mounting pattern, because this unit uses a 2 hole starter mount, 101mm mount centres, and M10x1.5 mount hole diameter. Those dimensions are the first checkpoint when replacing a starter on a Bosch style application.

The 12V electrical setup and 1.8kW power rating need to suit the vehicle’s starting system, and the clockwise rotation must also match the existing unit. A mismatch in rotation, pinion count, or nose cone length can stop the starter from engaging correctly, even if the mounting points look similar.

The listed 9 tooth pinion, 29mm pinion diameter, 20.5mm pinion at rest, and 244mm overall length are practical comparison points for confirming the replacement is the same type. If you are comparing a removed starter, matching these measurements and the Bosch unit designation is safer than relying on appearance alone.

This starter is described as new and carries a 3 year passenger / 1 year commercial warranty. Warranty coverage is useful, but it does not replace the need to verify physical fitment, electrical specification, and application details before installation.

For BMW and BMW 7 applications shown in the fitment information, use the exact build details and the original part number where possible. Vehicle model naming alone is not enough on starter motors, because the Bosch style setup and mounting dimensions can vary across the range.

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 BXS0161 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 BXS0161 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 BXS0161, 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 using part number BXS0161, the Bosch-style application, 12V rating, 2 hole mount, and the listed dimensions before purchase. If the original starter differs in rotation, tooth count, mount centres, or overall length, do not assume interchangeability.
