Bosch Starter Motor 12V 9 Tooth CW Part No. 1986S00685

This Bosch starter motor is a 12V unit with 9 teeth and clockwise rotation, identified by part number 1986S00685. It is supplied as one starter motor, with 2 mounting bores, and carries a 12 month warranty.

Bosch states this starter motor is manufactured using the same rigorous production standard as OE parts. It is designed for strong starting performance, with optimised internals aimed at maximum starting cycles and service life.

As a rotating electrical component, this starter motor suits buyers who need to match the electrical rating, rotation direction and tooth count before ordering. The key identifiers here are Bosch, 12V, CW rotation, 9 teeth and part number 1986S00685.

The listed fitment data points to a range of Holden, Mercedes-Benz and Opel applications, including Astra, Barina, Tigra, Trax, C-Class and Corsa variants. Even so, the safest way to confirm suitability is to compare the part number and application details against the vehicle already on the car.

Application and Buying Notes

Before ordering, confirm that your vehicle uses a 12V starter with clockwise rotation and a 9 tooth drive. Those details are the most direct technical checks in this listing, and they matter because starter motors must match the vehicle’s electrical setup and drive engagement correctly.

The part number 1986S00685 is the most reliable identifier to compare against the old unit, workshop paperwork or catalogue reference. If the existing starter motor has a Bosch number that matches, that is a strong starting point, but the mounting arrangement still needs to align because this unit has 2 mounting bores.

Fitment references include Holden, Mercedes-Benz and Opel applications, but the list is broad rather than a complete vehicle-by-vehicle guarantee. That means model badge alone is not enough; year, engine version, mounting pattern and drive tooth count all need to be checked before purchase.

Bosch notes OE-standard production and optimised internals for service life, which is useful when selecting a replacement starter for repeated starting use. Even with that standard, the correct fit depends on the vehicle application matching the listed 12V CW 9 tooth specification.

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 1986S00685 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.

Additional published details for cross-checking include Voltage 12, Product Group 2 STARTER MOTORS.

Bosch Starter Motor 12V 9Th CW. Part number 1986S00685 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 1986S00685, 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 HOLDEN ASTRA, HOLDEN ASTRA 2000, HOLDEN ASTRA 2001, HOLDEN ASTRA 2002, MERCEDES-BENZ C-CLASS, MERCEDES-BENZ C-CLASS 2007. 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.

Compatibility note: Confirm fitment by matching part number 1986S00685, 12V voltage, clockwise rotation, 9 tooth drive and the 2 mounting bores against the vehicle application before ordering. If there is any uncertainty, compare the existing starter motor and the vehicle’s catalogue details rather than relying on model name alone.
