Application and Buying Notes

Before ordering, match the part number 8201065 and confirm the starter mount layout. This unit uses a 3 hole mount with 126mm mount centres and a 13mm mounting hole, so the physical pattern needs to line up with the vehicle or engine already fitted.

The electrical and drive specifications are also important. This starter is 12V, clockwise rotation, 12 tooth, with a 44mm pinion, 48mm pinion at rest and a 7.8kW power rating. Those details need to suit the existing system and the application, especially where there is limited clearance around the bellhousing or starter location.

This starter is listed as new and carries a one year warranty. It is also described as suitable for wet or dry clutch applications, but the final check should always be made against the vehicle’s current starter details, mounting measurements and engine specification before purchase.

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 8201065 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.
