Application and Buying Notes

Before ordering, match the Bosch part number 1986S00874 against the removed starter or vehicle records. The 12V rating, 10 tooth pinion and clockwise rotation are the core identifiers on this unit, and they need to line up with the application you are replacing.

Physical fit matters as much as electrical fit on starter motors. Check the 3-hole mount pattern, the 108mm, 75mm and 74mm mount centres, the 64mm flange diameter and the 8.5 / 9 / M8 mount hole size so the replacement can sit correctly on the engine housing.

The listed fitment applications include Alfa Romeo Giulietta and Mito, Fiat 500, 500 C, 500X, Doblo, Panda, Punto and Ritmo, plus Jeep Renegade. Treat those as application references only and confirm the exact vehicle match by part number, year and mounting details before purchase.

This starter is rated at 2kW and is described as a dry unit, so it is important to compare the original starter’s mounting layout and clutch arrangement rather than relying on appearance alone. The 11mm pinion at rest measurement is another useful check when comparing like for like.

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 1986S00874 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.
