Application and Buying Notes

Before ordering, match the Bosch part number 1986S00856 with your original starter or the vehicle application details. The important mechanical and electrical checks here are 12V voltage, 10 teeth, clockwise rotation and 2 mounting bores.

Starter motors can look similar across different applications, so the part number is the safest way to confirm you are comparing the correct unit. Even where a Mercedes-Benz model appears in the fitment data, the exact variant, year and engine combination still need to be checked against the vehicle.

This starter is presented as an OE-style replacement, which means the intended focus is fit and performance alignment with the original starter rather than universal interchange. If your existing unit has the same 12V, 10T, CW setup and matching mounting layout, it is a strong candidate for comparison.

Packaging dimensions are listed as 32.5 cm length, 18 cm width and 13.9 cm height. Those measurements can help when checking storage, freight handling or workshop planning, but they do not replace vehicle fitment confirmation.

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 1986S00856 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.
