Application and Buying Notes

Before buying, match the 24V system, 10 tooth pinion, clockwise rotation, and Denso suit against the starter already fitted to the machine. The part number DXS566 is the most reliable reference, but the physical details also matter: 3 hole mount type, 89mm flange diameter, 127mm mount centres A, 90mm mount centres B and C, and 11mm mount holes.

The 310mm overall length, 40mm pinion diameter, and 48mm pinion at rest are useful checks where clearance around the bellhousing or mounting face is tight. If the old starter differs in tooth count, rotation, or mounting pattern, do not rely on appearance alone; confirm the specification match first.

This unit is listed as a new starter motor with a 5.5kW power rating and an earth stud. Those details are worth confirming on the vehicle or machine because electrical connection style and mounting arrangement can vary even within the same general make family. The stated fitment includes CASE, CASE IH, CATERPILLAR, and KOMATSU applications, but the exact model and engine combination still need to be checked against the listed part number and dimensions.

Warranty coverage is listed as 3 years for passenger applications and 1 year for commercial applications. If you are fitting this to agricultural, industrial, or heavy equipment, check your application type carefully and make sure the starter you remove has the same 24V, CW, 10 tooth, Denso-style configuration before proceeding.

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 DXS566 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 10Th CW Denso Style. Part number DXS566 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 DXS566, 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.

Available application references include CASE 580 SUPER E, CASE 580E, CASE 621, CASE 621B, CATERPILLAR 120H, CATERPILLAR 120K. 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.

Compatibility note: Confirm fitment by matching part number DXS566, the 24V CW 10 tooth Denso-style specification, and the mounting measurements before ordering.
