Application and Buying Notes

When comparing this starter motor, start with the part number 1986S10048, the 12V rating, and the 3 mounting bores. Those are the most useful checks for confirming whether it aligns with the unit already fitted to the machine.

The 9th CW description is a key identification point and should be matched carefully to the application you are working on. If the current starter differs in rotation or mounting arrangement, do not rely on the Bosch name alone.

The fitment list includes a range of Belarus, Carraro, Deutz-Fahr, Fendt, and Volvo NH12 applications, but the safest approach is still to confirm the exact vehicle or machine model, year where shown, and the existing part number. That is especially important on older machinery where specifications can vary within a model family.

The 12 months warranty provides a defined warranty period, but it does not remove the need to confirm compatibility first. This is a rotating electrical component, so the installation should be matched carefully to the machine’s existing starter and electrical setup.

Packaging dimensions of 39 x 23 x 16 may help when planning freight or workshop storage, but they do not indicate fitment. Fit should always be checked against the starter’s part number, 12V specification, rotation, and mounting bore count before fitting.

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 1986S10048 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 1986S10048 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number 1986S10048, 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 alternator 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.

Compatibility note: Please confirm compatibility using the Bosch part number 1986S10048, the 12V specification, 9th CW identification, and the 3 mounting bores against the machine’s existing starter and application details before ordering.
