Application and Buying Notes

Before ordering, compare the part number 0001125031 and the physical details on your original starter motor. The important matching points here are 12V, 10 teeth, CCW rotation, 3-hole mounting, 76mm flange diameter, and the 106mm / 102mm mount-centre measurements.

The 2kW rating and 28mm pinion diameter are useful checks when comparing units that may look similar but differ in output or engagement dimensions. The dry clutch listing is also worth confirming, because starter application details can vary even within the same vehicle family.

If you are replacing a Bosch starter, confirming the unit make and the mounting pattern is sensible before purchase. The listed 9mm mounting hole diameter, 53mm pinion at rest, and 234mm overall length give practical reference points for checking fit against the removed unit or the vehicle mounting space.

Although Volkswagen Transporter and Transporter / Caravelle applications are shown, the safest approach is still to match by part number and the exact starter specifications above. That is the best way to avoid ordering a unit that is close in appearance but different in tooth count, rotation, or mounting layout.

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 0001125031 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.
