Application and Buying Notes

For a starter motor like this, the key checks are the 24V system voltage, 11 tooth pinion, clockwise rotation, and the 3 hole mount with 126mm centres. The 39MT design, 92mm flange diameter, 420mm overall length, and 16mm mount hole diameter should all be compared with the removed unit before purchase.

Part No. 8201055 is the most reliable identifier to use when confirming compatibility. The listing also notes suitability for Delco units, but that should still be matched against the application and the physical dimensions, especially where equipment has been repaired, modified, or fitted with a non-original starter previously.

The 9kW power rating and insulated return are important when replacing a high-demand starter in heavy equipment or industrial applications. The unit is marked new, not remanufactured, and the one year warranty gives a clear service period, but it does not replace the need to verify the original starter details carefully.

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 8201055 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.

For part number 8201055, 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 ATLAS COPCO MT2010, ATLAS COPCO MT42, ATLAS COPCO MT431B, ATLAS COPCO MT436B, BCI EXPLORER, CASE 1221E. 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 One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility using Part No. 8201055, the 24V rating, 11 tooth CW configuration, and the listed 39MT mounting dimensions before ordering.
