Application and Buying Notes

When comparing this starter motor to the part on the vehicle, start with the part number 1986S00838 and then confirm the electrical and mechanical details: 12V, clockwise rotation, and 10 teeth. Those are the verified identifiers available here, and they are the most useful checks before purchase.

Starter motors are not suited to guesswork. Even if the unit looks similar, voltage, rotation direction, and tooth count need to match the application. A mismatch in any one of those details can stop the starter from engaging correctly or fitting as expected.

This Bosch unit is listed with a 12 month warranty and built to withstand harsh environments. That is useful context for workshop and repair use, but it does not replace a proper fitment check against the removed part, vehicle application details, or any matching part number already confirmed for the job.

If you are replacing a failed starter, compare the original label, connector arrangement, mounting style, and drive engagement details before ordering. Only the specifications supplied here should be relied on: Bosch, 12V, 10 tooth, CW, part number 1986S00838.

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 1986S00838 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.

For part number 1986S00838, 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.

The listed warranty is 12 Months. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by matching part number 1986S00838 and checking the vehicle application, 12V rating, clockwise rotation, and 10 tooth count before purchase.
