Bosch Starter Motor 12V 10 Tooth CW Part No. 1986S00855

This Bosch starter motor is a 12V unit with 10 teeth and clockwise rotation, listed under Part No. 1986S00855. It is supplied as one each and is intended for rotating electrical applications where the starter specification must match the vehicle’s original setup closely.

The unit carries OEM Number A287906060080 and has two mounting bores. Those details matter when you are checking interchange, because starter fitment is driven by electrical specification, mounting style, pinion tooth count, and rotation rather than appearance alone.

Bosch describes this starter motor as being designed in fit and performance to meet OE starters, with premium starting performance and build quality intended to withstand harsh environments. It is manufactured in China and covered by a one year warranty.

Packed measurements are 32.5 cm long, 18 cm wide, and 13.9 cm high. Those dimensions can help with handling and storage, but the key buying checks remain the 12V rating, 10 tooth pinion, clockwise rotation, and the listed part identifiers.

Application and Buying Notes

Before ordering, confirm that your original starter matches the 12V, 10 tooth, clockwise configuration and has two mounting bores. Those are the main physical and electrical identifiers for this Bosch unit, and they should be checked against the vehicle’s existing starter or parts information before purchase.

The part numbers are just as important as the visible shape. Use Bosch Part No. 1986S00855 and OEM Number A287906060080 as your reference points when matching the replacement. If the vehicle uses a different starter specification, a similar-looking unit may still be incorrect.

If you are replacing a faulty starter, compare the old unit’s tooth count, rotation direction and mounting bore arrangement before fitting. The listed packaging size of 32.5 x 18 x 13.9 cm is for the packed item and does not replace vehicle-level compatibility checks. One year warranty terms apply to the part as supplied.

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 1986S00855 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 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 MERCEDES-BENZ AMG GT, MERCEDES-BENZ AMG GT 2014, MERCEDES-BENZ AMG GT 2015, MERCEDES-BENZ AMG GT 2016.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching Bosch Part No. 1986S00855, OEM Number A287906060080, 12V specification, 10 tooth count, clockwise rotation and two mounting bores against the vehicle’s application details before ordering.
