This Denso starter motor is a new 12V light commercial unit with 13 teeth, clockwise rotation, and part number DXS643. It is listed as a 3 hole starter mount design with 128mm mount centres A, 90mm mount centres B and 90mm mount centres C, which gives you several clear points to compare against the unit you are replacing.

The stated power rating is 2.7kW, with a flange diameter of 89mm, an overall length of 290mm, and a mount hole diameter of 11.5mm. The pinion diameter is 39mm and pinion at rest is 48mm, so it is important to check the physical dimensions of the old starter as well as the mounting pattern before ordering.

Denso is the stated brand and the starter is described as suitable for Denso unit applications. It is supplied new, weighs 8.26kg, and carries a one year warranty. For buyers replacing an existing starter, the most useful checks are the part number DXS643, the 12V electrical setup, the clockwise rotation, and the 13 tooth pinion arrangement.

Application and Buying Notes

The most reliable way to confirm this starter is to match the part number DXS643 against the unit already fitted to the vehicle. Beyond the part number, compare the 12V rating, clockwise rotation, 13 tooth pinion, and the 3 hole mount pattern with 128mm, 90mm and 90mm mount centres.

Physical measurements matter on starter motors. The flange diameter of 89mm, overall length of 290mm, mount hole diameter of 11.5mm, and pinion diameter of 39mm are practical checkpoints when checking clearance and alignment against the existing starter and bell housing arrangement.

The unit is listed as a Denso starter motor for light commercial use, and it is described as designed in fit and performance to meet OE starters. That does not replace checking the application on your vehicle, especially if the current starter has been changed previously or if there are any signs the wiring, mounting, or drive engagement may differ from standard.

If you are unsure, remove the old starter and compare all visible markings and dimensions before purchasing. The pinion at rest measurement of 48mm, the 2.7kW power rating, and the 8.26kg weight can help you confirm whether the replacement matches what is already installed.

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 DXS643 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.
