OEX Alternator 12V 100A Delco 13SI Style DXA9136

The OEX DXA9136 is a new 12V alternator rated at 100A, made in Delco 13SI style and supplied as a pad-mount unit. It suits Delco applications where the 13SI series layout, 17mm shaft diameter, and internal regulator specification are the correct match.

Key physical details include mount centres A of 64mm, mount centres B of 71mm, mount centre to centre of 160mm, and an adjusting hole diameter of 10.5 / 12.5. The unit weighs 5.34kg and is listed with no pulley section applicable.

This alternator is identified with part number DXA9136 and OEM number 8600375, with pin code IR200. A 24V version is noted separately as DXA9137, so voltage checking is important before ordering. The listed warranty is one year.

OEX states its products are sourced from market leading OEM and aftermarket suppliers, with ISO9001 certified factory sourcing supporting engineering, testing, and quality control procedures. For a replacement alternator, the practical checks remain voltage, mounting pattern, regulator type, shaft size, and unit series.

Application and Buying Notes

Before ordering, confirm the vehicle or equipment uses a 12V Delco 13SI style alternator with an internal regulator and pad mount arrangement. The key matching points here are the 17mm shaft diameter, 64mm mount centres A, 71mm mount centres B, and 160mm mount centre to centre.

The 100A output is the rated charging capacity of this alternator, so it is worth matching that against the original unit rather than assuming a higher or lower amperage will suit. The listing also notes a 24V version as DXA9137, which makes voltage verification essential.

Check the physical mounting measurements carefully, especially the adjusting hole diameter of 10.5 / 12.5 and the mount leg thickness of 80mm. Small differences in bracket layout can prevent a correct fit even where the alternator looks similar.

Part number DXA9136 and OEM number 8600375 are the most useful identifiers to compare against the old alternator, invoice record, or parts catalogue reference. If the existing unit is marked as Delco 13SI style and the measurements line up, that is a strong starting point for confirmation.

This is a new alternator supplied as each, with a one year warranty. As with any rotating electrical part, the best practice is to verify the full application details before fitment so the replacement matches the original unit in voltage, mounting style, and regulator type.

The brand notes reference OEM and aftermarket sourcing plus ISO9001 certified factories, which supports the supply standard of the part, but it does not replace application checking. Confirm the part number, 12V system, and all listed dimensions before purchase.

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 DXA9136 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Mount Centres A 64mm, Mount Leg Thickness 80mm, Power Rating (Amp) 100, Regulator Type Internal, Shaft Diameter 17mm, Voltage 12, Alternator Mount Pad.

Additional published details for cross-checking include New / Reman. New, Weight 5.34kg, Product Group 1 ROTATING ELECTRICAL, Part No. DXA9136, Brand OEX, Description OEX Alternator 12V 100A Delco 13SI Style, Adjusting Hole Diameter 10.5 / 12.5, Mount Centres B 71mm, Pin Code IR200, Pulley Section Not Applicable.

OEX Alternator 12V 100A Delco 13SI Style. Part number DXA9136 should be checked first. Listed voltage is 12. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Internal. Pulley configuration is Not Applicable. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA9136, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

Compatibility note: Confirm fitment by matching part number DXA9136, OEM number 8600375, 12V system voltage, Delco 13SI style, internal regulator, pad mount arrangement, and the listed mounting dimensions before ordering.
