Application and Buying Notes

Before ordering, compare the part number DXS440, the 12V rating, the 9 tooth pinion, and the clockwise rotation against the starter you are replacing. The mount pattern is also specific: 3 hole mount type, 132mm / 89mm / 82mm mount centres, 88mm flange diameter, and M12x1.5 / 13 mount holes.

The listed fitment covers a range of applications including ASIA MOTORS ROCSTA, FORD COURIER, FORD ECONOVAN, MAZDA 626, MAZDA B-SERIES, MAZDA E-SERIES, MITSUBISHI INDUSTRIAL FORKLIFTS, and NISSAN SERENA. That makes exact matching important, because starter motors can vary by engine, transmission, mounting layout, and year.

If you are working from the old starter, check the pinion diameter of 29mm, the pinion at rest measurement of 7mm, and the overall length of 228mm. Those measurements help confirm that the replacement is physically comparable before installation.

For commercial use, the warranty is listed as 1 year, while passenger use is listed as 3 years. The unit is new, weighs 5.6kg, and is described as a Denso style starter, so confirming the original unit make and physical dimensions remains the best way to avoid a mismatch.

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 DXS440 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 DXS440, 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.
