Application and Buying Notes

Before ordering, compare the part number DXS4021, the 12V rating, and the clockwise rotation against your original starter. The 9-tooth pinion, 109mm mount centres, 66mm flange diameter, and 181mm overall length are all practical checks that help confirm whether this starter matches the existing unit.

This starter is specified as Denso style and suits Denso unit make applications, so the safest approach is to match both the physical measurements and the original unit style. If your vehicle or equipment uses a different mount arrangement, pinion size, or rotation direction, the part may not be suitable.

The listed dry clutch note matters where the starter location or drive arrangement differs from another application. The 29mm pinion diameter, 18mm pinion at rest measurement, and 10mm mount hole diameter are useful reference points when comparing against the removed starter or service information.

For commercial use, the warranty is listed at 1 year, while passenger use is listed at 3 years. Warranty terms do not replace fitment checking, so confirm the DXS4021 part number and all dimensional details before fitting or relying on the unit for a repair.

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 DXS4021 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.
