Application and Buying Notes

When comparing this starter motor to the one being replaced, start with the 24V rating, 12-tooth drive, clockwise rotation, and Bosch Part No. 1986S10047. Those are the clearest compatibility checks and should line up with the original unit before you proceed.

The mounting details matter just as much as the electrical rating. This unit uses a 3-hole mount with 126mm mount centres, a 92mm flange diameter, and 13.5mm mount holes, so the physical shape and bolt pattern need to match the vehicle application and the removed starter.

The drive end also needs to be checked carefully. The pinion diameter is 45mm and the pinion at rest measurement is 48mm, which helps confirm that the starter geometry matches the existing setup. If any of those measurements differ from your old starter, pause and compare again before ordering.

This is a new Bosch starter motor rather than a remanufactured unit, and it carries a 12-month warranty. The unit is listed as suitable for Bosch applications and is intended for dry-clutch use, so it is best matched to the specific application details rather than to a vehicle model name alone.

For fitment confidence, use the part number first, then confirm the voltage, rotation, tooth count, mounting pattern, flange diameter, and overall length. Those identifiers are the most reliable way to avoid ordering a starter that looks close but differs in one critical measurement.

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 1986S10047 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 24V 12Th CW. Part number 1986S10047 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 1986S10047, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment using Bosch Part No. 1986S10047, the 24V specification, 12-tooth CW rotation, and the listed mounting and dimension details before purchase. Vehicle fitment should always be checked against the original starter and application information.
