The OEX Alternator BXA9012 is a 12V, 90A unit built in a Bosch style configuration. It is supplied as a new alternator, with internal regulation and a single-leg alternator mount, making the key physical and electrical checks straightforward before ordering.

This unit is listed with a 17mm shaft diameter, 184mm mount centre-to-centre, 51mm mount leg thickness, 9.5mm pivot hole diameter and M8 adjusting hole diameter. Those dimensions are the important reference points when comparing against the existing alternator on the vehicle or equipment.

The application data supplied for this part includes Thermo King equipment references, so it is worth matching the unit make, mount layout and connector details carefully before purchase. As with any alternator, the safest approach is to confirm the part number BXA9012, the Bosch-style fit, and the listed measurements against the original unit.

OEX notes this product is sourced from market leading original equipment manufacturers and aftermarket suppliers, and that OEX products are sourced from ISO certified factories. The alternator is supported by a 3-year passenger and 1-year commercial warranty, which is useful context for buyers comparing replacement options.

Application and Buying Notes

Before ordering, compare the original alternator against the BXA9012 part number and the listed Bosch style configuration. The most useful physical checks here are the single-leg mount, 184mm mount centre-to-centre measurement, 51mm mount leg thickness, 9.5mm pivot hole diameter, M8 adjusting hole and 17mm shaft diameter.

Electrical matching matters as much as the bolt pattern. This alternator is 12V with a 90A output and an internal regulator, so the replacement should suit that charging setup rather than a different voltage or externally regulated arrangement.

The supplied application references point to Thermo King equipment, but the fit still needs to be confirmed against the exact unit and the existing alternator installed on it. Even within the same brand family, mount style and dimensions are the deciding factors.

If the current alternator is unavailable, use the part number, mount layout and measurement set to cross-check before fitting. Weight is listed at 5kg, which can also help when comparing boxed replacements or checking whether the new unit is materially similar to the one removed.

For commercial equipment, it is sensible to check the vehicle or machine’s charging requirements and duty cycle before choosing a 90A unit. The listed warranty is 3 years for passenger use and 1 year for commercial use, so it is also worth understanding how the product will be used 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 BXA9012 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 12V 90A Bosch Style. Part number BXA9012 should be checked first. Listed voltage is 12. Listed output rating is 90. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single Leg. Regulator type is Internal. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA9012, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include THERMO KING CG-II, THERMO KING CG-II 1990, THERMO KING CG-II 1993, THERMO KING RC-II. 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.

Compatibility note: Confirm compatibility by matching part number BXA9012, Bosch style, 12V, 90A, internal regulator, single-leg mount and the listed dimensions against the original alternator and application details before ordering.
