Application and Buying Notes

Check the part number DXS644 against the removed starter motor before ordering. The clearest matching points here are 12V operation, 9 tooth pinion, CCW rotation, Denso suit, pad mount style and the listed dimensions of 68mm mount centres, 62mm flange diameter and 204mm overall length.

If you are replacing a starter that has been in service for some time, compare the old unit carefully rather than relying on appearance alone. The 29mm pinion diameter, 9mm pinion at rest and 8mm mount hole diameter are useful checkpoints when confirming the starter will physically line up with the original application.

The listed 0.6kW power rating should be considered alongside the vehicle’s original starter specification. A starter motor is not a universal part, and the correct match depends on the full application details as well as the dimensions and rotation direction.

Because no vehicle makes or models are supplied here, the safest buying approach is to verify the original part number, mounting style and tooth count from the vehicle or removed component. If anything differs, pause and confirm before fitting. Starter motors need to match closely to avoid installation issues.

This unit is described as a new dry clutch starter motor, so it is intended for dry applications rather than wet clutch use. The one year warranty may provide extra confidence, but it does not replace the need to confirm the physical and electrical details first.

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 DXS644 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.

For part number DXS644, 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.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

Compatibility note: Confirm compatibility by matching part number DXS644, 12V rating, 9 tooth count, CCW rotation, Denso suit, pad mount style and the listed dimensions against the original starter motor and vehicle application details before purchase.
