Application and Buying Notes

When matching a starter motor, the safest check is the part number and the physical dimensions. For DXS551, the key identifiers are 12V, 14 teeth, CCW rotation, 65mm flange diameter, 83mm mount centres, and a 2 hole starter mount. If any of those details differ from the original unit, the starter may not be the correct match.

The listed fitment references include AVANT 313S, CASE 60, DITCH WITCH 100SX and 1030, HONDA SMALL GX340 and GX390, HUSQVARNA CONSTRUCTION LG400, TORO TX413, and VERMEER RTX130, V1150, and V1350. These are application references only, so the exact machine variant and engine setup still need to be checked against the part number and the old starter.

The pinion details are also worth checking closely. This unit has 14 teeth, a 32mm pinion diameter, and 9mm pinion at rest, which helps confirm whether the gear engagement and mounting arrangement are consistent with the original starter. A mismatch in tooth count or pinion position can prevent correct installation even when the machine family appears similar.

Because this is a new OEX starter motor, it is intended as a replacement electrical part rather than a rebuilt unit. The 0.5kW rating, dry clutch type, and 1.82kg weight provide additional comparison points when you are cross-checking against the original starter or a removed sample.

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 DXS551 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 14Th CCW Denso Style. Part number DXS551 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 DXS551, 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.

Compatibility note: Confirm fitment using the part number DXS551, the 12V 14T CCW Denso style specification, and the measured mounting and pinion dimensions before ordering. Application names are helpful, but the final check should always be against the original starter motor and the machine’s exact setup.
