Application and Buying Notes

Before ordering, compare the part number DXS4044 and OEM number 428000-7840 with the starter being replaced. That is the most reliable starting point when the vehicle application is not listed, especially with a Denso-style starter motor and 2 hole mount arrangement.

The dimensions matter as much as the electrical rating. Check the 130mm mount centres A, 74mm flange diameter, 45mm nose cone length and 212mm overall length against the existing unit, along with the 30mm pinion diameter and 12mm pinion at rest measurement.

This unit is a 12V, 1kW starter with 9 teeth and clockwise rotation. Those details must align with the vehicle’s original starter configuration, because starter motors need the same rotation, tooth count and mounting layout to suit correctly.

It is listed as suitable for dry clutch applications, so confirm the vehicle setup before fitting. If the original starter differs in clutch type, mount style or physical dimensions, do not rely on the description alone to make the match.

For commercial use, the warranty listed is 1 year. For passenger use, the warranty listed is 3 years. Keep purchase details and the original part identification handy in case you need to confirm the replacement against the installed unit.

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 DXS4044 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 DXS4044, 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.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm fitment by matching part number DXS4044, OEM number 428000-7840, the 12V 9 tooth clockwise configuration, and the listed mounting and dimensional measurements against the original starter before purchase.
