OEX Alternator 24V 70A Cummins 3415691

The OEX Alternator 24V 70A Cummins 3415691 is a new rotating electrical component supplied as each, with a 24 volt system and 70 amp output. It is listed with an internal regulator, an 8 groove pulley section, clockwise rotation, and a twin leg alternator mount, so the mounting style and electrical setup should be checked carefully before purchase.

This unit is identified under part number 3415691 and OEM number 3415691, with Cummins listed as the unit make. Key mounting dimensions include 71mm inside mounting legs, a 13mm pivot hole diameter, and an M12x1.75 adjusting hole diameter. Those details matter when matching the alternator to the existing bracket layout and adjustment hardware.

The pulley outside diameter is 65mm and the connection note lists B = Battery, N = Phase, E = Earth, and L = Light. For any alternator replacement, confirming the connector layout, pulley configuration, voltage, and mounting points is the safest way to avoid ordering the wrong unit.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, and from ISO9001 certified factories. This alternator is backed by a one year warranty and is sold under the OEX brand, with a weight listed at 8.12kg.

Application and Buying Notes

Before ordering, match the part number 3415691 against the alternator already fitted to the vehicle or machinery. The listed Cummins application, 24V system, and 70A output are important checks, but they should be confirmed against the existing unit because alternators that look similar can differ in mounting, pulley, or connector details.

The mounting dimensions are especially useful here: 71mm inside mounting legs, a twin leg mount, a 13mm pivot hole diameter, and an M12x1.75 adjusting hole diameter. If any of those points differ from the current alternator, the unit may not line up correctly even where the electrical rating appears close.

Also confirm the pulley and rotation details before purchase. This alternator has an 8 groove pulley section, a 65mm pulley outside diameter, and clockwise rotation. Those details need to suit the belt arrangement and drive direction already on the vehicle or equipment.

The connection note is another practical checkpoint: B = Battery, N = Phase, E = Earth, and L = Light. If the plug or terminal arrangement on the existing alternator is different, the unit may require wiring changes or may not be suitable for direct replacement.

The listed one year warranty applies to the OEX alternator as sold, but it does not replace the need to confirm fitment. Matching the OEM number 3415691, the Cummins application, and the physical dimensions is the best way to reduce the risk of ordering the wrong part.

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 3415691 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, Inside Mounting Legs 71mm, Power Rating (Amp) 70, Pulley Section 8 Groove, Rotation CW, Voltage 24, Alternator Mount Twin Leg, OEM Number 3415691.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. 3415691, Brand OEX, Description OEX Alternator 24V 70A Cummins, Adjusting Hole Diameter M12x1.75, Pivot Hole Diameter 13, Pulley Outside Diameter 65mm, Regulator Type Internal, Suits Unit Make Cummins.

OEX Alternator 24V 70A Cummins. Part number 3415691 should be checked first. Listed voltage is 24. Listed output rating is 70. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. 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 3415691, 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 70 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: Please confirm fitment by matching OEM number 3415691, the Cummins application, the 24V 70A rating, and the stated mounting, pulley, and connection details against the existing alternator before ordering.
