Application and Buying Notes

When replacing a starter motor, the most important checks are voltage, rotation, mounting points, and the part number. This Bosch unit is a 24V starter motor with 11th clockwise rotation and 3 mounting bores, so those details should line up with the existing part and the vehicle’s electrical system before anything is fitted.

The fitment information supplied points to a Scania application range, including S-Series, 4-Series, K-Series, T-Series, and related bus variants. That is useful guidance, but it is still best practice to confirm the exact vehicle application against 1986S10089 rather than relying on model name alone, because starter motors can vary between series, years, and configurations.

This part is described as being designed in fit and performance to meet OE starters and built to withstand harsh environments. Those are sensible indicators for heavy commercial use, but they do not replace a proper comparison of the removed starter motor, the mounting bore pattern, and the rotation specification before ordering.

If you are matching a Bosch replacement, check the identification plate or part number on the existing unit where possible. The part number 1986S10089, the 24V system, and the 11th CW designation are the most reliable ordering details in this listing, and they should be matched carefully against the vehicle application and any workshop records.

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 1986S10089 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 1986S10089, 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 heavy comm in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include S - SERIES 2016, S - SERIES 2017, SCANIA 4 - SERIES, SCANIA 4 - SERIES 1996, SCANIA 4 - SERIES 1997, SCANIA 4 - SERIES 1998. 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.

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 compatibility with part number 1986S10089, 24V system voltage, 11th clockwise rotation, and the 3-mounting-bore configuration before ordering. If the existing starter motor details do not match, do not assume fitment from vehicle name alone.
