Application and Buying Notes

For starter motors, the safest match is a combination of part number and physical specification. This Bosch unit is part number 1986S00651, runs on 12V, has a 0.9kW power rating, and uses 9 teeth with clockwise rotation, so those details should be checked against the original starter before purchase.

The mounting and nose dimensions are just as important as the electrical rating. This unit has a 2 hole starter mount type, a 68mm flange diameter, and a 23mm pinion at rest. If any of those measurements differ from the existing starter, it may not be the correct replacement even if it looks similar externally.

This starter is listed for dry clutch applications and is described against MINI and MINI MINI fitment data. Because starter motors can vary within the same model range, use the vehicle details, the original unit, and the part number together rather than relying on model name alone.

If you are replacing a failed starter, compare the old unit for tooth count, rotation direction, mounting pattern, and flange size before fitting. The 12 month warranty applies to the Bosch starter motor itself, but correct application still depends on matching the specifications to the vehicle.

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 1986S00651 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.
