The OEX Alternator DXA9137 is a new 24V, 85A unit in Delco 13SI style, supplied as a pad-mount alternator with an internal regulator. It is listed with an 8 groove pulley, 60mm pulley outside diameter, and a weight of 6.48kg, which are the key details to check against the vehicle or equipment being serviced.

This alternator is identified as Suit Unit Make: Delco and carries OEM Number 8600366. The mounting details provided are Mount Centres A 64mm, Mount Centres B 70mm, Mount Cnt to Cnt 160mm, Mount Leg Thickness 80mm, and Adjusting Hole Diameter 10.5 / 12.5. Those measurements matter when comparing the replacement unit to the existing alternator before purchase.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified to support engineering, testing and quality control procedures. This alternator is backed by a one year warranty and is sold as each, which makes the part number DXA9137 and the listed dimensions the safest points of reference when confirming suitability.

Application and Buying Notes

Before ordering, compare the part number DXA9137 with the alternator currently fitted to the vehicle or machine. The key identifying details here are 24V, 85A, Delco 13SI style, pad mount, internal regulator, and OEM Number 8600366, so those items should all line up with the existing application.

The mounting measurements are just as important as the electrical rating. Check Mount Centres A 64mm, Mount Centres B 70mm, Mount Cnt to Cnt 160mm, Mount Leg Thickness 80mm, and Adjusting Hole Diameter 10.5 / 12.5 against the removed unit, because small differences in these dimensions can stop the alternator from sitting correctly or lining up with the belt drive.

The pulley is an 8 groove design with a 60mm outside diameter, so belt section and pulley alignment need to be confirmed before fitting. That is especially important where the original alternator has been replaced previously or where the vehicle has been altered, as the wrong pulley or mount arrangement can create installation problems even when the voltage and amperage appear close.

The note showing a 12V version, DXA9136, is a useful cross-check if you are comparing options. This 24V unit is a different application, so do not use the 12V reference as a substitute unless you have confirmed the correct electrical system and matching part details for your vehicle or equipment.

OEX backs this alternator with a one year warranty, but warranty cover does not replace fitment verification. The safest buying approach is to match the part number, confirm the 24V charging system, and compare the listed mount and pulley details with the original unit before installation begins.

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 DXA9137 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) 85, Pulley Section 8 Groove, Series 13SI, Voltage 24, Alternator Mount Pad.

Additional published details for cross-checking include New / Reman. New, Weight 6.48kg, Product Group 1 ROTATING ELECTRICAL, Part No. DXA9137, Brand OEX, Description OEX Alternator 24V 85A Delco 13SI Style, Adjusting Hole Diameter 10.5 / 12.5, Mount Centres B 70mm, Pin Code IR200, Pulley Outside Diameter 60mm.

OEX Alternator 24V 85A Delco 13SI Style. Part number DXA9137 should be checked first. Listed voltage is 24. Listed output rating is 85. 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 8 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA9137, 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 24 and output 85 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.

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 fitment by matching DXA9137, the 24V 85A specification, the Delco 13SI style, and the listed mounting and pulley measurements to the existing alternator before ordering.
