Application and Buying Notes

When matching this starter motor, the safest checks are the part number DXS641, the 12V system voltage, and the physical layout: 9 teeth, clockwise rotation, 2-hole mounting, 130mm mount centres, and an 89mm flange diameter. A starter can look similar yet differ in tooth count, rotation, or mounting pattern, so those details matter just as much as the vehicle model.

The pinion diameter is 29mm, the pinion at rest is 16mm, and the overall length is 212mm. These measurements help confirm the replacement will sit and engage as expected in the existing application. The unit is listed as dry and weighs 3.10kg, which is useful when comparing against a removed starter or an existing supplier reference.

For the best result, confirm the machine’s Denso application and match the part number DXS641 against the starter already fitted. If there is any doubt about rotation, mount centres, or flange diameter, it is better to verify those points first than to rely on appearance alone.

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 DXS641 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.

Denso Starter Motor 12V 9Th CW. Part number DXS641 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 DXS641, 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.

Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm compatibility by checking part number DXS641, 12V voltage, clockwise rotation, 9 teeth, 2-hole mounting, 130mm mount centres, 89mm flange diameter, and the application details before purchase.
