Application and Buying Notes

When replacing a starter motor, the safest match is the part number and the physical specification set. For this Bosch unit, check 0001107421, 12V, 9 teeth, clockwise rotation, and the 2-hole mounting arrangement before ordering.

The flange diameter is 82.5mm and the pinion at rest is 27mm, so it is worth comparing those measurements against the removed starter if the vehicle application is not confirmed. The mounting hole angle measurement is 42°, which is another useful check where the original unit is still available.

If you are matching by application rather than by the removed part, use the vehicle details carefully and compare them against the confirmed fitment notes. The fitment data supplied here includes AUDI A6 applications, including 2004, 2005 and 2006 models, but the part number should still be checked first.

A 1.2kW starter is suitable only where that output, rotation direction and mounting style are the correct match for the vehicle. Avoid assuming compatibility from brand alone, even when the replacement is Bosch and described as OE-quality.

The one year warranty applies to this new starter motor, but warranty cover does not replace the need to confirm fitment before installation. Once fitted, electrical and mechanical compatibility must be correct for the starter to operate as intended.

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 0001107421 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 9Th CW. Part number 0001107421 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 0001107421, 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 fitment using Bosch part number 0001107421, the 12V 9 tooth CW specification, and the vehicle application details before purchase or installation.
