Bosch Starter Motor 12V 9 Tooth CW 1.1KW Part No. 1986S00669

This Bosch starter motor is a new 12V unit with 9 teeth, clockwise rotation, and a 1.1kW power rating. It carries part number 1986S00669 and is listed as a 2 hole starter mount with M10x1.5 mount hole diameter, which are the key details to check against the original starter before ordering.

Physical dimensions matter with starters, and this unit measures 201mm overall length with an 82mm flange diameter. The pinion at rest is 26mm, the pinion diameter is 26mm, and the mounting centres are 105mm, so it is best matched by comparing the complete mounting and nose configuration rather than relying on appearance alone.

The application detail supplied for this starter is Mercedes-Benz Sprinter and Vito with OM611 engine. A fitment list is available for Mercedes-Benz and Ssangyong applications, but the safest way to confirm suitability is to match the part number 1986S00669 and check the starter’s tooth count, rotation, mount type, and measurements against the vehicle’s original part.

Application and Buying Notes

Before ordering, compare the part number 1986S00669 with the starter you are replacing, then check the practical match points: 12V voltage, 9 tooth drive, clockwise rotation, 2 hole mount, and 105mm mount centres. These details are the strongest indicators when selecting a starter motor, especially where the vehicle may have had more than one starting system option over its life.

The dimensions are also important on this Bosch unit. The 82mm flange diameter, 201mm overall length, M10x1.5 mount hole diameter, and 26mm pinion size should all be checked against the original starter or the vehicle’s catalogued application. A starter can look similar in photos yet differ in mounting depth, bolt pattern, or pinion arrangement.

This starter is listed for Mercedes-Benz Sprinter and Vito with OM611 engine, so engine code confirmation is worth doing before purchase. If the vehicle has been modified, engine-swapped, or the existing starter does not match the original specification, the safest approach is to verify by part number and measurements rather than assuming a visual match.

The unit is a new starter motor with a 12 month warranty and a weight of 3.034kg. That gives a useful baseline for checking what is being replaced and helps when comparing freight, handling, or the condition of an old unit that may be heavier due to corrosion, wear, or a different housing design.

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 1986S00669 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty 12 Months, Mount Centres A 105mm, Number of Teeth 9, Pinion at Rest 26mm, Power Rating 1.1kW, Voltage 12, Starter Mount Type 2 Hole, Weight 3.034kg.

For part number 1986S00669, 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.
