Application and Buying Notes

When matching a starter motor, the key checks are voltage, rotation, mounting arrangement and the part number. This Bosch unit is 24V, 9th CW, with 3 mounting bores and part number 1986S10105, so those details should be compared directly with the existing starter or the vehicle application before purchase.

The fitment listing supplied references Mercedes-Benz LK/LN2, NG, T2/LN1 and Unimog applications. If your vehicle falls within one of those families, confirm the exact chassis or build details as well as the starter configuration, because similar-looking starters can differ in rotation, mounting pattern or electrical specification.

Heavy commercial starter motors are expected to tolerate hard use, but the correct match still depends on the vehicle’s requirements. The stated 24V system and 9th clockwise rotation are the most important technical checks here, especially where previous repairs, conversions or replacement engines may have changed what is fitted.

A 12-month warranty is listed for this Bosch starter motor. As with any electrical component, keep the packaging and installation records, and make sure the charging system and cables are in good order before fitting, so the replacement unit is not affected by an underlying vehicle fault.

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 1986S10105 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.
