OEX Alternator 24V 110A Bosch Style BXA4021

The OEX Alternator BXA4021 is a new 24V, 110A unit designed in a Bosch style configuration. It uses an internal regulator, twin leg alternator mount, and an 8 groove pulley, so the physical layout and drive setup need to match the application before fitting.

Key dimensions include 105mm inside mounting legs, 198mm mounting centre-to-centre, an 11mm adjusting hole diameter, a 13mm pivot hole diameter, a 17mm shaft dimension, and a 62mm pulley outside diameter. These measurements are the practical checkpoints that matter when confirming whether the alternator will line up correctly in the vehicle or machine.

OEX lists this alternator as suitable for Bosch units, and it is supplied as a new rotating electrical component. The unit weighs 7.6kg and carries a 3 year passenger / 1 year commercial warranty, which gives a clear reference point for buyers comparing replacement options by electrical output and mounting pattern.

Application and Buying Notes

Before ordering, match the part number BXA4021 and check the Bosch style application carefully against the vehicle or machine already fitted. The key physical points on this alternator are the 24V electrical system, 110A output, twin leg mount, and 8 groove pulley, so the existing unit should be checked for the same mounting and drive arrangement.

Mounting measurements are just as important as the electrical rating. This alternator has 105mm inside mounting legs, 198mm centre-to-centre mounting, a 13mm pivot hole, an 11mm adjusting hole, and a 17mm shaft dimension. If any of those points differ from the original unit, the alternator may not sit correctly even if the plug or general style appears close.

This is a new alternator, not a remanufactured unit, and it uses an internal regulator. For replacement work on heavy vehicles and equipment, that means the existing charging system layout needs to be checked before purchase, especially if the original alternator had a different regulator type or pulley section.

The listed application data spans several BRUKS, John Deere, Liebherr, Neuson Forest, Sandvik, and Volvo references, but compatibility still comes down to the exact machine build and the alternator already installed. If you are comparing against another Bosch style alternator, use the part number, mounting pattern, pulley type, and voltage rating together rather than relying on the brand name alone.

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 BXA4021 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 24V 110A Bosch Style. Part number BXA4021 should be checked first. Listed voltage is 24. Listed output rating is 110. 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 BXA4021, 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 110 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include BRUKS 1006 2014, JOHN DEERE 120D, JOHN DEERE 120D 2008, JOHN DEERE 160D LC, JOHN DEERE 160D LC 2008, LIEBHERR PR714. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment by checking BXA4021, the 24V 110A specification, Bosch style layout, twin leg mounting, 8 groove pulley, and the recorded dimensions against the unit currently fitted to the machine.
