Bosch Starter Motor 12V 9 Tooth CW 1986S00936

The Bosch Starter Motor 12V 9 Tooth CW is a rotating electrical component supplied as a starter motor, with Bosch part number 1986S00936. It is a 12 volt unit with clockwise rotation, a 9 tooth pinion, and a 36mm pinion diameter, so it is important to compare those details carefully with the unit being replaced.

This starter motor uses a 3 hole starter mount type and has a 92mm flange diameter. The pinion at rest measures 24mm, and it is listed for dry clutch applications. Those physical details matter as much as the voltage rating when you are matching a starter for replacement.

Bosch lists the unit as built to withstand the harshest environments, and it is covered by a 12 month warranty. As with any starter motor, correct fitment depends on matching the part number, mounting style, rotation, tooth count, and pinion dimensions before ordering.

Application and Buying Notes

Before ordering, confirm the replacement starter matches Bosch part number 1986S00936 and compare the 12V rating, clockwise rotation, 9 tooth count, and 3 hole mounting arrangement against the original unit. Those identifiers are the most reliable checks when a vehicle listing is not supplied.

The pinion dimensions are also important here: this unit has a 36mm pinion diameter and a 24mm pinion at rest, with a 92mm flange diameter. If any of those measurements differ from the starter already fitted to the vehicle, the part may not be suitable even if the external appearance seems close.

This starter motor is listed for dry clutch applications, so buyers should verify that application detail before fitting. When replacing an electrical starter, it is also worth checking the condition of the battery, cabling, terminals, and earth connections, because poor supply or connection issues can be mistaken for starter failure.

The unit is sold each and includes a 12 month warranty. Keep the part number and the original removed unit for comparison during installation, especially if the vehicle has had previous repairs or non-original components fitted. Accurate matching at the bench is the safest way to avoid downtime and repeat removals.

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 1986S00936 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 1986S00936 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 1986S00936, 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.

Compatibility note: Confirm fitment by matching Bosch part number 1986S00936, the 12V specification, clockwise rotation, 9 tooth pinion, 36mm pinion diameter, 92mm flange diameter, 3 hole mount, and dry clutch application before purchase or installation.
