OEX Alternator 12V 105A Delco 15SI Style DXA9104

The OEX Alternator DXA9104 is a new 12V, 105A alternator in Delco 15SI style, supplied as a single-leg mount unit for applications that suit a Delco 15SI pattern. Key mounting details include a 51mm mount leg thickness, 184mm mount centre-to-centre, 10mm pivot hole diameter, and M10x1.5 adjusting hole diameter, so it is important to compare the physical dimensions carefully before ordering.

This alternator uses an internal regulator, clockwise rotation, and an A section pulley with a 67mm pulley outside diameter. The shaft dimension is 17mm, and the unit weighs 7.06kg. Those details matter when you are replacing a charging component in a machine that already uses a Delco-style 15SI setup, because the mounting, pulley, and regulator arrangement all need to match the vehicle’s existing layout.

OEX lists this part as suitable for Delco units, with Part No. DXA9104 and Pin Code IR133. It is backed by a 3 year passenger / 1 year commercial warranty, and is supplied as a new alternator rather than a remanufactured unit. That makes it a practical choice where the buyer wants a fresh replacement with clear identification and known electrical output.

Application and Buying Notes

Before ordering, compare the listed mounting dimensions against the unit being replaced. This alternator is a single-leg mount design with 51mm mount leg thickness, 184mm mount centre-to-centre, a 10mm pivot hole, and an M10x1.5 adjusting hole. If any of those dimensions differ from the existing unit, the part may not physically install correctly even if the electrical output looks similar.

The pulley and rotation details are also important. This model has a 67mm outside diameter pulley, an A section pulley profile, and clockwise rotation. Those points should be checked against the old alternator and belt arrangement, because the wrong pulley section, pulley size, or rotation direction can affect belt alignment and charging performance.

The alternator is rated at 105A and uses an internal regulator, so it should be matched to the vehicle’s charging system requirements rather than selected on mounting shape alone. The part is listed for Delco 15SI style applications, but fitment should still be confirmed by part number, physical measurements, and the vehicle’s exact application details before purchase.

This unit is supplied new and carries a 3 year passenger / 1 year commercial warranty. That warranty detail is useful for buyers who need to distinguish between passenger and commercial use, but it does not replace the need to confirm the exact alternator family, mounting style, and pulley arrangement on the vehicle.

The supplied fitment information covers a wide range of agricultural and industrial applications, including AGCO Allis, Allis Chalmers, Case, Case IH, Gleaner, International Harvester, New Holland, White, and selected John Deere references. Because those listings are application-based rather than a universal guarantee, it is best to cross-check the vehicle model and the part number DXA9104 before committing to 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 DXA9104 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.
