Application and Buying Notes

Before ordering, match the Bosch part number 1986S00731 with the starter already fitted to the vehicle, then confirm the key hardware details: 12V electrical system, 10-tooth pinion, clockwise rotation, and 2-hole mount. A starter motor can look close to correct while still differing in rotation, tooth count, or mounting pattern, so these checks matter.

The listed dimensions are there for a reason. Confirm the 105mm mount centres, M10x1.5 mount hole diameter, 82.5mm flange diameter, 237mm overall length, and 26mm pinion at rest against the existing unit or service information. If any of those measurements differ, fitment should be checked carefully before installation.

This unit is a new Bosch starter motor with a 2.2kW power rating. That specification is useful when comparing replacement options, but it should not be treated as the only selection point. The safest approach is to verify the vehicle application, the starter mount type, and the part number together rather than relying on one detail alone.

The supplied fitment information includes Mercedes-Benz 124, C-Class, E-Class, G-Class, M-Class, S-Class, SL, Sprinter variants, Valente, Vario, Viano, Vito and Vito / Mixto, plus Ssangyong Korando and Musso. Because those names cover multiple model years and configurations, confirm the exact application against the vehicle’s existing starter and the full identification details before purchase.

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 1986S00731 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 1986S00731, 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.

Available application references include 5-T 2006, 5-T 2007, 5-T 2008, 5-T 2009, MERCEDES-BENZ 124, MERCEDES-BENZ 124 1992. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.
