The Bosch Starter Motor 24V 10 Tooth CW is a 4kW starter motor identified by part no. 1986S10040. It is a 3-hole mounting unit with 3 mounting bores, a 89mm flange diameter, and a clockwise rotation, which makes the physical layout and electrical setup important to confirm before purchase.

Key dimensions on this unit include 127mm mount centres A, 90mm mount centres B, 90mm mount centres C, a 40mm pinion diameter, and 48mm pinion at rest. The starter uses a 10 tooth pinion and is specified as dry clutch compatible, so matching the application details to the vehicle is essential.

This starter motor is listed under Bosch branding and is manufactured in China. It carries a 12 month warranty and is described as built to withstand the harshest environments, which suits buyers looking for a heavy-duty 24V starter with clear dimensional data for comparison.

Application information supplied with this part includes IVECO Eurocargo and IVECO Tector references. Because starter fitment depends on more than just model name, the safest approach is to compare the part number 1986S10040, the 24V rating, 10 tooth count, clockwise rotation, and the mounting dimensions against the vehicle currently fitted.

Application and Buying Notes

Before ordering, check the part number 1986S10040 against the existing starter and confirm the 24V electrical system matches the vehicle. This unit is a 4kW Bosch starter with clockwise rotation and a 10 tooth pinion, so those details need to align with the application you are replacing.

Mounting details are just as important as electrical specifications. Verify the 3-hole starter mount, 3 mounting bores, 89mm flange diameter, and mount centres of 127mm, 90mm and 90mm. If any of these points differ from the original starter, it may not be the correct replacement.

The pinion measurements also matter when comparing parts. This starter has a 40mm pinion diameter and 48mm pinion at rest, which should be checked carefully where access allows. Those figures are useful for confirming whether the starter matches the removed unit and avoids ordering on model name alone.

Application references supplied with the part include IVECO Eurocargo and IVECO Tector. These references are helpful, but they are not a substitute for checking the installed part number and the measured mounting points on the vehicle, especially where multiple starter variants have been used.

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 1986S10040 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.

Relevant published details for this unit include Type STARTER MOTOR, Unit of Measure EACH, Warranty 12 Months, Mount Centres A 127mm, Mount Centres C 90mm, Pinion at Rest 48mm, Power Rating 4kW, Voltage 24, Wet / Dry Clutch Dry, Packaging length 39.

Bosch Starter Motor 24V 10Th CW. Part number 1986S10040 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 1986S10040, 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.

Available application references include IVECO EUROCARGO, IVECO EUROCARGO 2000, IVECO EUROCARGO 2001, IVECO EUROCARGO 2002. 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.

Compatibility note: Confirm compatibility by matching part number 1986S10040, 24V system voltage, 10 tooth CW configuration, and the listed mounting dimensions against the vehicle and the existing starter before purchase.
