Application and Buying Notes

When replacing a starter motor, the most useful checks are the electrical rating, pinion tooth count, rotation direction and mounting pattern. For this Bosch unit, the key identifiers are 12V, 13 tooth, clockwise rotation, 3 mounting bores and part number 1986S00873.

The pinion at rest measurement is 0.5mm, so the existing unit should be compared carefully if you are matching by physical dimensions. The packaging size is 32.5 x 18 x 13.9, which can also be helpful where access or freight handling is a consideration.

This starter is specified for dry clutch applications. That detail matters because starter design and application should suit the vehicle’s transmission and engine arrangement. If the vehicle already has a Bosch starter fitted, checking the label details and the original part number is the safest way to verify the match.

The supplied fitment preview shows BMW and MINI applications, including BMW 2, BMW X1, MINI, MINI Clubman and MINI Countryman references. Even where a model family appears in the fitment list, the correct choice still depends on the exact vehicle build and the starter’s matching specification.

A starter motor can look similar to another unit while differing in tooth count, mounting bores or rotation. Matching the part number 1986S00873, together with the 12V and 13 tooth CW specification, is the best way to reduce the risk of ordering the wrong 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 1986S00873 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.

For part number 1986S00873, 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: Please confirm vehicle fitment using part number 1986S00873 and the listed application details, including 12V, 13 tooth, clockwise rotation, 3 mounting bores and dry clutch specification, before purchasing.
