OEX Alternator 12V 72A Delco 10SI Style DXA9102

The OEX Alternator DXA9102 is a new 12V, 72A unit in Delco 10SI style, suited to applications that call for a single-leg alternator with an internal regulator. It is listed with a 168mm mount centre-to-centre dimension, 51mm mount leg thickness, 10mm pivot hole diameter, and 8mm adjusting hole diameter.

This alternator uses a 60mm outside diameter pulley with an A section belt profile, and the shaft dimension is 17mm. For buyers matching a replacement by physical dimensions, those measurements matter just as much as the 12V and 72A electrical rating.

It is a new rotating electrical component supplied under the OEX brand, with part number DXA9102 and pin code IR133. The stated warranty is 3 years for passenger use and 1 year for commercial use, which is useful to note when comparing it with other replacement alternators.

The unit is described as Delco 10SI style and suits Delco applications. As with any alternator replacement, confirming the regulator type, pulley style, mounting arrangement, and part number before ordering helps avoid incorrect fitment.

Application and Buying Notes

Before ordering, compare the part number DXA9102 and the physical details of your existing alternator against this unit’s 12V, 72A specification. The mounting arrangement is single leg, with a 168mm mount centre-to-centre dimension, 51mm mount leg thickness, a 10mm pivot hole, and an 8mm adjusting hole.

The pulley details are important if you are replacing a working alternator rather than changing the whole belt drive. This unit has a 60mm outside diameter pulley with an A section belt profile, so the belt width and pulley type should be checked against the vehicle or machine already fitted.

The regulator is internal, which is a key compatibility point on Delco 10SI style applications. If the current alternator uses a different regulator arrangement, or the mounting points and shaft size do not match, the replacement may not be suitable even if the electrical output looks close.

The listed fitment includes a range of machinery and vehicles, including Allis Chalmers, Bobcat, Case, Chevrolet, Clark, Hyster, International, Jeep, and John Deere applications. That does not replace a proper check of the existing unit, because alternator interchange can vary by build, equipment configuration, and previous repairs.

This alternator weighs 4.95kg and is supplied new, so it is intended as a direct replacement option where the dimensions and Delco 10SI style match. Use the part number, mount style, pulley section, and voltage rating together when confirming the correct unit.

If you are buying for commercial use, note the warranty is 1 year commercial and 3 years passenger. That is worth considering alongside the part number, because duty cycle and operating conditions can be very different between road use and plant or industrial use.

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 DXA9102 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 Alternator 12V 72A Delco 10SI Style. Part number DXA9102 should be checked first. Listed voltage is 12. Listed output rating is 72. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Pulley configuration is A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA9102, 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.

Compatibility note: Confirm fitment by matching part number DXA9102, Delco 10SI style, 12V 72A rating, single-leg mounting, internal regulator, and the stated pulley and hole dimensions to your existing alternator before ordering.
