Application and Buying Notes

When matching a starter motor, the most useful identifiers are the 24V rating, 9-tooth count, clockwise rotation, 3 mounting bores, and part number 1986S10084. Those details need to line up with the vehicle’s original unit, because even a close-looking starter can differ in drive engagement or mounting.

The fitment list points to Scania 2-Series applications, including 1985 through 1988 examples. That is helpful, but it is not enough on its own to confirm compatibility for every vehicle in that range. Check the existing starter motor, wiring arrangement, mounting points, and any labels or numbers already on the unit.

Bosch describes this starter as designed in fit and performance to meet OE starters and built for harsh environments. Those are useful indicators for a heavy-duty replacement part, but the practical decision still comes down to matching the vehicle application and the physical specifications already listed.

If you are replacing a starter that has failed intermittently, pay close attention to the original part number and tooth count before making a purchase. The wrong tooth engagement, rotation direction, or mounting pattern can stop the starter from operating correctly even when the voltage appears suitable.

The 12 month warranty applies to the listed unit, and the packaging size of 39 x 23 x 16 cm may help if you are arranging freight or workshop storage. For a clean installation, compare the old starter against the new one before the vehicle is reassembled.

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 1986S10084 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 9Th CW. Part number 1986S10084 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 1986S10084, 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: Confirm compatibility using part number 1986S10084, 24V, 9 teeth, clockwise rotation, and 3 mounting bores, then verify the specific Scania application before ordering.
