Application and Buying Notes

Before ordering, compare the 24V system voltage, clockwise rotation, and 11-tooth pinion against the original starter on the machine or vehicle. The DXS451 is a Denso-style starter motor with a 3-hole mount, so the mounting pattern needs to line up as well as the electrical and drive details.

The mounting dimensions are specific: 135mm mount centres A, 111mm mount centres B, 111mm mount centres C, 105mm flange diameter, and 13mm mount holes. Those measurements are the best checks when you are confirming whether this starter will physically suit the application.

The listed application groups cover a wide range of equipment and vehicles, including Doosan/Daewoo, Dynapac, Hitachi, Isuzu, JCB, Kato, Kawasaki, Kobelco, Komatsu, Link-Belt, Sakai, Sumitomo, Takeuchi and TCM. Even within those groups, matching by part number, mount layout, rotation and tooth count remains the safest approach.

Because starter motors are often fitted across multiple variants, model names alone are not enough to confirm compatibility. Check the original unit details, especially the 24V rating, 11 teeth, CW rotation and the 295mm overall length, before placing the order.

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 DXS451 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 24V 11Th CW Denso Style. Part number DXS451 should be checked first. Listed voltage is 24. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number DXS451, 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 24 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
