Bosch Starter Motor 12V 9 Tooth CW 1.1KW Part No. 1986S00687

This Bosch starter motor is a 12V, clockwise-rotation unit with 9 teeth and a 1.1kW power rating. It is supplied as a new starter motor, carries part number 1986S00687, and is identified as a Bosch unit designed around OE-style fit and performance.

Key physical details include a 2-hole starter mount, 105mm mount centres, 76mm flange diameter, 200mm overall length, and an M10x1.5 / 11 mount hole diameter. The pinion measures 29mm in diameter and sits 25.5mm from rest, so these measurements are important when comparing against the original starter on the vehicle.

This unit is listed as suitable for Bosch applications and is intended for dry clutch use. It is sold individually as each, weighs 3.038kg, and is covered by a 12 month warranty, giving you a clear reference point for replacement planning and identification.

Application and Buying Notes

Before ordering, match the part number 1986S00687 and compare the starter’s physical dimensions with the unit currently fitted to the vehicle. The important checks here are 12V voltage, 9 tooth pinion, clockwise rotation, 2-hole mount, 105mm mount centres, and 76mm flange diameter.

The pinion details matter as much as the electrical rating. This starter uses a 29mm pinion diameter with a 25.5mm pinion at rest, so it is worth confirming the nose housing and engagement position against the original part. A mismatch in those measurements can prevent correct installation even when the vehicle family appears similar.

For applications where multiple starter options may exist, the safest approach is to compare the original starter number, the mount hole diameter of M10x1.5 / 11, and the overall length of 200mm. The listed dry clutch design should also be checked against the vehicle’s original configuration.

This Bosch unit is supplied new rather than remanufactured, and the 1.1kW rating gives a useful benchmark when comparing replacements. If the vehicle previously used a different output or rotation, do not assume interchangeability without checking the original starter and vehicle application details carefully.

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 1986S00687 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 1986S00687 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 1986S00687, 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 BMW 1, BMW 1 2005, BMW 1 2006, BMW 1 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: Please confirm fitment by matching part number 1986S00687 and comparing the vehicle application, 12V voltage, 9 tooth count, clockwise rotation, 2-hole mount, and the listed measurements before purchase.
