Application and Buying Notes

Before ordering, match the part number BXS0157, the Bosch style application, and the core dimensions that are listed for this starter motor. The 12V electrical setup, CW rotation, 9 tooth pinion, and 2 hole mounting pattern all need to align with the vehicle’s original starter requirements.

The mount centres are 105mm, the flange diameter is 82mm, and the overall length is 206mm. Those measurements are practical checks when comparing against the original unit, particularly where there is limited clearance around the bellhousing or mounting face.

The pinion details are also worth confirming carefully. This unit lists a 26mm pinion diameter, 27.5mm pinion at rest, and a dry clutch arrangement. Those details help distinguish it from similar-looking starter motors that may not match the same engagement setup.

Warranty terms differ between passenger and commercial use, so it is sensible to confirm how the vehicle will be used before purchase. The listed cover is 3 years for passenger use and 1 year for commercial use, which should be considered alongside the vehicle application and service expectations.

If the original starter has been replaced before, compare the old unit’s tag, mounting pattern, and shaft/pinion dimensions rather than relying on appearance alone. Bosch style starters can share broad similarities, but the listed measurements and 9 tooth count are the reliable checks for this part.

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 BXS0157 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.

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 part number BXS0157, the Bosch style application, 12V CW specification, 9 tooth pinion, and the listed mounting and length measurements against the vehicle’s original starter before ordering.
