Bosch Alternator 12V 65A BXH1223N

The Bosch Alternator BXH1223N is a 12V, 65A replacement alternator supplied as a new unit, with an internal regulator and twin leg mount arrangement. It is listed with a 74mm pulley outside diameter, A-section pulley, clockwise rotation, and inside mounting legs measuring 82mm.

This alternator is identified with pin code IR49 and is specified as suitable for Bosch applications. The unit is sold each and carries a one year warranty. Those details matter when matching an alternator, because mounting style, pulley profile, rotation, and electrical output all need to line up with the vehicle’s charging system requirements.

For buyers comparing options, the key identifiers here are Bosch, part number BXH1223N, 12 volts, and 65 amps. If you are replacing an existing alternator, it is worth checking the old unit’s mounting ears, pulley size, pin code, and regulator type before ordering, as those are the practical points that usually decide whether the part will suit the application.

Application and Buying Notes

When checking whether this Bosch alternator will suit your vehicle, start with the part number BXH1223N, then confirm the 12V charging system, 65A output, and internal regulator arrangement. The physical details are just as important: twin leg mount, 82mm inside mounting legs, 74mm pulley outside diameter, A-section pulley, and clockwise rotation all need to match the vehicle’s original setup.

If you are replacing an existing alternator, compare the connector or pin code, which is listed here as IR49, with the unit already fitted to the vehicle. Matching the pin code helps avoid ordering the wrong electrical connection style, especially where the alternator is mounted correctly but the plug or terminal arrangement differs.

The listed Nissan Navara fitment points to model years from 1992 through 1998 in the supplied data, but that should still be treated as a guide rather than a blanket guarantee. Small changes across model series, engine variants, or charging system revisions can alter the correct alternator, so the safest approach is to verify the old unit and the vehicle application before fitting.

For trade or workshop use, the one year warranty and new unit status are useful points when planning a replacement job. The alternator is described as being made from high quality raw materials, corrosion resistant, and using a reduction drive to maintain continual speeds for easier starting, but those features should be viewed as product characteristics rather than a promise of a specific outcome on every vehicle.

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 BXH1223N 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 Part No. BXH1223N, Brand BOSCH, Description Bosch Alternator 12V 65A, Inside Mounting Legs 82mm, Power Rating (Amp) 65, Pulley Section A, Rotation CW, Voltage 12, New / Reman. New, Product Group 1 ROTATING ELECTRICAL.

Bosch Alternator 12V 65A. Part number BXH1223N should be checked first. Listed voltage is 12. Listed output rating is 65. 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXH1223N, 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 65 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include NISSAN NAVARA, NISSAN NAVARA 1992, NISSAN NAVARA 1993, NISSAN NAVARA 1994. 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: Please confirm fitment with part number BXH1223N and check the alternator mount, pulley dimensions, rotation, pin code IR49, and vehicle application details before ordering.
