Application and Buying Notes

The most important checks on this starter are the part number 1986S10098, the 11-tooth pinion, clockwise rotation, and the 3 mounting bores. Those details need to match the starter already fitted to the vehicle or the replacement comparison part before purchase.

The product details list both 24V in the description and 12V in the specifications, so voltage must be confirmed carefully against the vehicle and the removed unit. Do not rely on the title alone when electrical components are involved, as a voltage mismatch can prevent correct operation.

If you are matching to a Volvo application, the fitment list includes F10, F12, FL10, FM10, N10, N12, NL, TD100, TD102FL and TD12# references. Even where a model appears in the fitment list, it is still best practice to check the exact engine, year, and starter configuration against the old part number and mounting pattern.

The listed warranty is 12 months, and the starter is described as being built for harsh environments. That makes it a sensible replacement option where durability matters, but it should still be selected on confirmed fitment rather than assumption.

Packaging dimensions are shown as 49.7 x 20 x 23, which may be useful if you are comparing freight, storage, or bench handling requirements. For fitment-critical jobs, the physical layout and connection points remain more important than packaging size, so use the removed starter as the final reference where possible.

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 1986S10098 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 11Th CW. Part number 1986S10098 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 1986S10098, 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.

Compatibility note: Please confirm compatibility using part number 1986S10098, the 11-tooth CW specification, the 3 mounting bores, and the vehicle’s voltage and application details before ordering.
