Bosch Starter Motor 12V 9T CCW 2.0KW 1986S00809

The Bosch Starter Motor 12V 9T CCW is a rotating electrical component with part number 1986S00809, supplied as a 2.0kW unit for 12V applications. It uses a 9 tooth pinion, a 25.8mm pinion diameter, and counter-clockwise rotation, so the electrical and mechanical details need to match the vehicle application before purchase.

This starter motor has a 2 hole mount design with 2 mounting bores, a 76mm flange diameter, and a pinion at rest measurement of 32.5mm. Those dimensions are useful when comparing against the removed starter, especially where the mounting pattern and nose housing style must line up exactly.

Bosch lists this starter motor as designed in fit and performance to meet OE starters, with premium starting performance and build quality intended to withstand harsh environments. It is suitable for wet or dry clutch applications, and it carries a 12 month warranty.

Application and Buying Notes

Before ordering, confirm the part number 1986S00809 against the starter removed from the vehicle, along with the 12V rating, 9 tooth pinion, CCW rotation, and 2 hole mount pattern. Those are the key identifiers provided here and are the safest way to check that the replacement matches the application.

The flange diameter is 76mm, the pinion diameter is 25.8mm, and the pinion at rest measurement is 32.5mm. These dimensions matter when comparing the new starter with the existing unit, particularly where the nose housing, drive gear position, or mounting face must align correctly.

A 2.0kW starter can be an important match point where cranking load is a concern, but the correct fit still depends on the full combination of voltage, rotation, gear count, and mount style. If any of those details are uncertain, compare the old unit carefully before fitting.

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 1986S00809 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 12V 9Th CCW. Part number 1986S00809 should be checked first. Listed voltage is 12. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 1986S00809, 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.

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.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm compatibility using part number 1986S00809 and the listed application details, including 12V, 9 tooth, CCW rotation, 2 hole mount, and the stated dimensions before purchase.
