Bosch Starter Motor 24V 12T CW 7.8KW Part No. 1986S10097

The Bosch Starter Motor 24V 12T CW is a rotating electrical component supplied as an individual unit, with a 24 volt rating, 12 teeth, clockwise rotation, and Bosch part number 1986S10097. It is listed with a 7.8kW power rating, a 3-hole starter mount, and 3 mounting bores, which are the key identifiers to check before ordering.

Physical dimensions are also important on a starter of this type. The unit is listed with 126mm mount centres A, 126mm mount centres B, and 126mm mount centres C, along with a 92mm flange diameter, 358mm overall length, 45mm pinion diameter, and 48mm pinion at rest. These measurements help confirm the starter will suit the intended application and mounting arrangement.

Bosch describes this starter as designed to withstand harsh environments and to meet OE starter fit and performance, with premium starting performance and planetary gear reduction noted. It is manufactured in China and carries a 12 month warranty, so the main checks remain the electrical rating, mounting style, and exact part number before purchase.

Application and Buying Notes

Before ordering, compare the Bosch part number 1986S10097 with the existing starter or the vehicle’s required replacement part. For starters, the part number, 24V electrical rating, 12-tooth pinion, and clockwise rotation are the first details that need to match the application.

Mounting details matter just as much as the electrical specification. This unit is listed with a 3-hole starter mount, 3 mounting bores, 126mm mount centres A/B/C, and a 92mm flange diameter, so the physical fit needs to be checked against the original unit or the mounting face on the application.

The listed 7.8kW power rating and 17.8kg weight indicate a substantial starter assembly, so allowance should be made for handling, installation access, and correct support during fitting. The overall length of 358mm, pinion diameter of 45mm, and 48mm pinion at rest are also useful checks where clearance is tight.

Bosch notes planetary gear reduction and OE-style fit and performance, but those are not substitutes for confirming the exact application. The safest way to buy a starter motor is to verify the part number, voltage, tooth count, rotation, and mounting measurements before finalising the order.

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 1986S10097 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.

Bosch Starter Motor 24V 12Th CW. Part number 1986S10097 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 1986S10097, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Please confirm compatibility using Bosch part number 1986S10097, the 24V specification, 12-tooth CW configuration, and the listed mounting and measurement details before purchase.
