Bosch Starter Motor 12V 2.2KW 9 Tooth CW Part No. 1986S00737

This Bosch starter motor is a 12V, clockwise-rotation unit with a 2.2kW power rating and 9 teeth on the pinion. It is listed as an Original Equipment part and carries part number 1986S00737, which is the key identifier to match when checking application and replacement suitability.

It is a new starter motor, supplied each, with a 3-hole starter mount type and three mounting bores. Key dimensions include 116mm mount centres A, 82mm mount centres C, 82mm mount centres B, 85mm flange diameter, 238mm overall length, and a 29mm pinion diameter.

The listed fitment covers selected Alfa Romeo and Fiat applications, including Alfa Romeo 147 and 159, plus Fiat Doblo, Punto, and Ritmo variants. As with any starter motor, confirm the mounting layout, tooth count, rotation, voltage, and part number before ordering, because those details must line up with the vehicle application.

Application and Buying Notes

Before ordering, compare the part number 1986S00737 with the original starter on the vehicle and check the physical mount setup. This unit is a 12V Bosch starter motor with a 3-hole mount type, 9 teeth, 116mm mount centres A, 82mm mount centres B, 82mm mount centres C, and an 85mm flange diameter, so the mounting pattern needs to match the application exactly.

The rotation is clockwise, which matters on starter motors just as much as voltage and tooth count. If the vehicle uses a different rotation, tooth count, or pinion dimension, the part may not be suitable even if the vehicle make appears similar.

Measure or compare the overall length of 238mm, the 29mm pinion diameter, and the 8.5mm pinion at rest if you are replacing a unit that has been removed. These dimensions help confirm that the starter is the correct physical match, especially when the original part is missing, damaged, or unreadable.

The listed fitment includes selected Alfa Romeo and Fiat applications, but the safest approach is to verify against the vehicle’s existing part and the application details rather than relying on model name alone. Variations can exist between series and build years, so the starter motor should be checked against the original unit and the vehicle’s specific requirements.

This starter is supplied as a new Bosch unit and carries a one-year warranty. That gives you a clear baseline for replacement work, but installation quality, battery condition, cable condition, and the vehicle’s charging and starting system still need to be checked during diagnosis.

If you are unsure, compare the starter mount type, mounting bores, tooth count, rotation, and voltage together. Those five details are the most useful compatibility checkpoints on this unit and will usually tell you more than the vehicle badge alone.

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 1986S00737 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 1986S00737 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 1986S00737, 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 ALFA ROMEO 147, ALFA ROMEO 147 2005, ALFA ROMEO 147 2006, ALFA ROMEO 147 2007, FIAT DOBLO, FIAT DOBLO 2010. 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 using part number 1986S00737 and the vehicle’s application details before purchase. Match the 12V specification, clockwise rotation, 9-tooth pinion, 3-hole mount type, and mounting dimensions to the original starter motor.
