Bosch Starter Motor 12V 10T CW 2.5KW - Part No. 0001109401

This Bosch starter motor is a new 12V unit with 10 teeth, clockwise rotation, and a 2.5kW power rating. It is identified by part number 0001109401 and is listed as a self-supporting starter with a 2 hole mount type, which makes the physical dimensions and mounting points important to check before purchase.

The key mounting measurements are 121mm mount centres, 10.5mm mount hole diameter, 70mm flange diameter, and 257mm overall length. The pinion measures 33mm in diameter, with a pinion at rest of 35.4mm. Those dimensions matter because starter motors are commonly matched by both electrical specification and housing layout, not by appearance alone.

This unit is a Bosch starter motor, manufactured in Hungary, and supplied as a new rotating electrical component. It carries a one year warranty and is described as suitable for dry clutch applications. If you are replacing a starter on a vehicle that originally used Bosch unit 0001109401, the part number and mounting details should be the first points to confirm.

Application and Buying Notes

When comparing this starter motor, use the part number 0001109401 together with the mounting measurements: 121mm mount centres, 2 hole fixing, and 10.5mm mount holes. A starter can look similar from the outside and still differ in flange diameter, pinion depth, or rotation, so these details should be checked against the removed unit or vehicle documentation before ordering.

The 12V electrical rating and 2.5kW power rating are the main electrical identifiers here, but the physical fit is just as important. The unit is listed as clockwise rotation with 10 teeth and a 33mm pinion diameter, so the tooth count and rotation direction need to match the application exactly. That is especially relevant when comparing starter motors that may share the same brand but not the same mounting pattern.

This starter is described as suitable for dry clutch use and as a self-supporting starter. Those are useful compatibility checkpoints when you are dealing with a replacement on a Jeep application, because they help narrow the match beyond vehicle make alone. If the original starter carries a different Bosch number, different mount centres, or a different rotation direction, it should not be assumed to be interchangeable.

For the best result, compare the removed unit to the listed measurements in full: 257mm overall length, 70mm flange diameter, 4.08kg weight, and 35.4mm pinion at rest. Those figures are practical checks for clearance and mounting alignment, and they can prevent the common error of choosing a starter that is close in appearance but wrong in specification.

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 0001109401 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 10Th CW. Part number 0001109401 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 0001109401, 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.

Available application references include JEEP CHEROKEE, JEEP CHEROKEE 2008, JEEP CHEROKEE 2009, JEEP CHEROKEE 2010. 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 fitment using Bosch part number 0001109401, the 12V clockwise configuration, and the supplied mount and pinion measurements before purchase. Do not rely on vehicle make alone; match the starter against the existing unit or application details.
