Bosch Starter Motor 12V 9 Tooth CW 1986S00671

This Bosch starter motor is a 12V unit with 9 teeth and clockwise rotation, listed under part number 1986S00671. It sits in the rotating electrical category and is supplied as one each, which makes it a straightforward replacement option when the original starter matches the same electrical and drive details.

The key identifiers for checking suitability are the 12 volt rating, 9-tooth engagement, and CW rotation. Those details matter because starter motor fitment is determined by the combination of voltage, pinion tooth count, rotation direction, and the application-specific mounting and drive arrangement.

Bosch describes this starter motor as being designed in fit and performance to meet OE starters. That is a useful indicator for buyers who want a replacement that follows the original style and specification as closely as possible, while still needing to confirm the part number and application details before ordering.

Application and Buying Notes

When comparing this starter motor to the unit being replaced, check the 12V rating first, then confirm the 9-tooth pinion and CW rotation. Those three details are the most practical starting point for a correct match, especially where the original starter is still available for comparison.

Part number 1986S00671 is the strongest reference point provided here, so it should be used alongside the vehicle application information on the existing starter or parts catalogue. Starter motors can look similar while still differing in tooth count, rotation, or mounting detail, so the identifying numbers should always be verified before purchase.

Because no vehicle list is supplied, fitment cannot be confirmed from model or engine details alone. If you are replacing an existing Bosch or equivalent starter, compare the label, casing, and drive end of the old unit with the 12V, 9-tooth, CW specification shown here.

The listed 12 month warranty applies to the part as supplied, but it does not replace the need to confirm compatibility. Careful matching matters most on starter motors, where the wrong rotation direction or pinion specification can prevent proper engagement with the ring gear.

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 1986S00671 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 CW. Part number 1986S00671 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 1986S00671, 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: Confirm fitment using part number 1986S00671, the 12V rating, 9-tooth count, and CW rotation before ordering. If the existing unit differs in any of those details, do not assume interchangeability.
