Application and Buying Notes

Before ordering, match the part number 0001121402 wherever possible, then compare the physical and functional details of the original starter. The key points here are 12V voltage, 1.1kW output, 10 teeth, CCW rotation, and the floating pinion design.

The mounting pattern is just as important as the electrical specification. This starter uses a 2-hole mount with 2 mounting bores, a 12.5mm mount hole diameter, a 76mm flange diameter, and a 42° mounting hole angle measurement, so the replacement should be checked against the existing starter or the vehicle application data.

Overall length is listed at 210mm and pinion at rest at 62mm. Those dimensions can matter when space around the bellhousing is tight, and they are useful reference points when comparing a removed starter against the replacement unit.

This Bosch starter is described as designed in fit and performance to meet OE starters, but that still does not replace a proper fit check. If the original unit is not available, compare the starter type, rotation, tooth count, and mount layout before fitting an order into a job.

The unit is listed as new and carries a one-year warranty. That gives you a clear basis for replacement, but the safest purchase is still the one that matches the original starter’s part number and mounting arrangement exactly.

Because no vehicle applications are supplied here, it is best to treat this as a specification-matched part rather than a model-matched part. If there is any doubt, confirm the original Bosch number, check the starter nose and flange dimensions, and verify the rotation direction before installation.

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 0001121402 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.
