Application and Buying Notes

For an alternator replacement, the safest check is to compare the part number BXA4040, the Bosch style application, and the physical fit details on the existing unit. The important points here are the 12V system, 140A output, internal regulator, single leg mount, and 6 groove pulley, because these features need to line up with the vehicle's charging system and belt setup.

Measurement checks matter just as much as the electrical rating. Confirm the 56mm mount leg thickness, 157mm mount centre to centre, 11mm pivot hole diameter, 11mm adjusting hole diameter, and 51mm pulley outside diameter against the removed alternator. If any of those differ, the unit may not physically mount or align correctly even if it looks close.

The 7kg weight and new condition are also useful when comparing replacement options, but they do not replace an actual fitment check. Buyers should use the vehicle application, the part number, and the mounting details together, especially where the vehicle list includes SAAB 9-3 and SAAB 9-5 references in the supplied fitment data.

Warranty coverage is listed as 3yr Passenger and 1yr Commercial. That is a useful guide for the expected use category, but it should be read alongside the stated application and the installation condition. If the original alternator has been changed previously, the safest approach is to match by the existing unit rather than relying on model 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 BXA4040 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. BXA4040, Brand OEX, Description OEX Alternator 12V 140A Bosch Style, Adjusting Hole Diameter 11, Pin Code IR189, Power Rating (Amp) 140, Pulley Section 6 Groove, Suits Unit Make Bosch, Alternator Mount Single Leg.

OEX Alternator 12V 140A Bosch Style. Part number BXA4040 should be checked first. Listed voltage is 12. Listed output rating is 140. 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. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXA4040, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include SAAB 9-3, SAAB 9-3 1998, SAAB 9-3 1999, SAAB 9-3 2000. 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 with part number BXA4040, Bosch style application details, and the listed mounting and pulley measurements before purchase. Do not rely on vehicle model name alone.
