Application and Buying Notes

Check the part number DXA9105 first, then compare the 12V rating, 60A output, Delco 20SI style and twin leg mounting before ordering. The key physical checks on this alternator are the 198mm mount centre-to-centre, 101mm inside mounting legs, 22mm shaft diameter and 13mm pivot hole diameter.

This alternator uses an internal regulator and is described as a brushless unit, so it should only be selected where that configuration matches the vehicle or equipment already fitted. The listed applications cover a range of Caterpillar, Clark, International, Iveco, John Deere and Massey Ferguson models, but the exact fit still depends on the original alternator and bracket dimensions.

Because alternators can look similar while carrying different mounting and electrical details, it is worth verifying the shaft size, adjusting hole style and overall mount layout against the removed unit. The weight is 8.26kg, which can also help when comparing a replacement in the workshop or on the shelf.

The warranty listed for this OEX alternator is 3yr Passenger and 1yr Commercial. That is useful for buying confidence, but it does not replace the need to confirm the application, as the correct fit is still determined by the part number, the Delco 20SI style and the measured mounting points.

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 DXA9105 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 DXA9105, 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 alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 60 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using part number DXA9105, the Delco 20SI style, and the stated mounting and electrical specifications before ordering. If the existing unit does not match the 12V, 60A, twin leg, internal regulator configuration or the listed hole and shaft dimensions, do not assume compatibility.
