Bosch Starter Motor 12V 13T CCW 1986S01001

This Bosch starter motor is a new 12V unit with a 13-tooth pinion, counter-clockwise rotation, and a 1.7kW power rating. It is listed as an Original Equipment part and carries part number 1986S01001, which is the key identifier to check against your existing starter or application details before ordering.

The unit is designed with a 2 hole starter mount, 105mm mount centres, an 11mm mount hole diameter, a 74mm flange diameter, and an overall length of 247mm. Those dimensions matter when comparing replacement starters, because mounting pattern and physical length need to match the vehicle setup as well as the electrical requirements.

It operates on 12 volts and uses a 33.5mm pinion diameter with 53mm pinion at rest. For buyers replacing a starter motor, the safest approach is to compare the part number, voltage, tooth count, rotation, and mounting measurements together rather than relying on description alone.

Application and Buying Notes

Before ordering, confirm the replacement starter matches part number 1986S01001 and the same basic specifications: 12V, 13 teeth, CCW rotation, and a 2 hole mount with 105mm mount centres. These are the most reliable checkpoints for avoiding an incorrect match when comparing starter motors.

Physical dimensions are just as important as electrical details. The listed flange diameter is 74mm, overall length is 247mm, mount hole diameter is 11mm, and the pinion diameter is 33.5mm. If any of these differ from the unit being replaced, the starter may not fit or may not align correctly with the ring gear.

This starter is specified as a Bosch unit and an Original Equipment part, which helps when cross-checking like-for-like replacements. It is still worth inspecting the existing starter label, mounting pattern, and tooth count on the vehicle side before fitting, especially where previous repairs, engine swaps, or non-standard parts may be involved.

The warranty listed is one year, and the unit is sold each. If you are comparing options, use the part number, voltage, rotation, tooth count, and mounting measurements as the main reference points. Those details are more useful than general shape alone when identifying a compatible starter motor.

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 1986S01001 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.

Additional published details for cross-checking include Packaging height 13.9, Product Group 2 STARTER MOTORS, Part No. 1986S01001, Brand BOSCH, Description Bosch Starter Motor 12V 13Th CCW, Flange Diameter 74mm, Mount Hole Diameter 11, Overall Length 247mm, Pinion Diameter 33.5mm.

Bosch Starter Motor 12V 13Th CCW. Part number 1986S01001 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 1986S01001, 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 part number 1986S01001, 12V rating, 13-tooth CCW configuration, and the listed mounting and dimension details against your existing starter and vehicle application before purchase.
