Application and Buying Notes

Before ordering, confirm the starter is a Denso style unit and check the part number DXS549 against the old starter or the machine’s parts listing. The key dimensions here are 12V, 15 teeth, CW rotation, 120mm mount centres and a 2 hole mount with 13mm mount holes.

The 2.0kW rating matters because starter output needs to suit the application, not just the bolt pattern. The pinion details are also important: this unit has a 22mm pinion at rest, a 44mm pinion diameter and is listed for dry clutch use.

Because starter motors can share similar housings while differing in rotation, tooth count or mounting dimensions, it is best to compare the old unit side by side where possible. The 95mm flange diameter and 220mm overall length are useful cross-checks when space and mount position are tight.

If the existing starter has been replaced before, rely on the physical dimensions and the DXS549 part number rather than the outer appearance alone. This is especially important on equipment families where several starter variants may be listed across similar models.

Warranty support is listed as 3 years for passenger use and 1 year for commercial use. That does not replace the need to verify fitment first, but it does give a clear ownership guide once the correct application is confirmed.

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 DXS549 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.

OEX Starter Motor 12V 15Th CW Denso Style. Part number DXS549 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 DXS549, 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.

Available application references include AIRMAN AX48U-6A, AIRMAN AX55U-6A, AIRMAN PDS185S, AMMANN ARX36, AMMANN ARX40, AMMANN ARX45. 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 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching part number DXS549, 12V, 15 tooth CW rotation, Denso style application, 2 hole mounting pattern, 120mm mount centres and the listed pinion and flange dimensions before ordering.
