Bosch Starter Motor 12V 9 Tooth CW 1.8KW Part No. 0001109040

Bosch starter motor, 12V, 9 tooth, clockwise rotation, part number 0001109040. This is a new starter motor with a 1.8kW power rating, 2-hole starter mount, and a self-supporting design for applications that match those dimensions and configuration details.

The unit has a 73mm flange diameter, 119mm mount centres, 11mm mount hole diameter, and 255mm overall length. It is listed with 9 teeth, a 25mm pinion diameter, and 40mm pinion at rest, so the physical and electrical match should be checked carefully before ordering.

This Bosch unit is made in Hungary and carries a one year warranty. It is described as suitable for Land Rover applications including 110/127, Defender, Discovery and Range Rover references in the provided fitment data, but confirmation against the vehicle application and the part number remains essential.

For buyers replacing an existing starter, the key checks are voltage, rotation, tooth count, flange and mount dimensions, and whether the vehicle uses a dry clutch starter arrangement. Those details matter as much as the vehicle model name when identifying the correct part.

Application and Buying Notes

Before ordering, compare the part number 0001109040 with the starter already fitted to the vehicle, then check the key physical details: 12V, 9 teeth, clockwise rotation, 73mm flange diameter, 119mm mount centres, 11mm mount holes, and 255mm overall length. Matching the vehicle family alone is not enough if the mounting pattern or pinion details differ.

The 1.8kW rating gives a useful reference when comparing against the current starter, particularly where there has been a previous replacement or conversion. The 25mm pinion diameter and 40mm pinion at rest are also important measurements for confirming correct engagement and fitment layout.

For Land Rover applications, the provided fitment data includes 110/127, Defender, Discovery and Range Rover references. Use that as a guide only and verify the exact model, year and existing starter details before purchase, especially on vehicles that may have had engine or electrical changes over time.

This unit is sold as a new Bosch starter motor and includes a one year warranty. If you are replacing a failed starter, inspect the mounting face, electrical connections and surrounding space for signs of damage or wear, because those issues can affect how the replacement starter sits and operates even when the part number is correct.

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 0001109040 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.
