Bosch Alternator 12V 110A BXH1230N

The Bosch Alternator BXH1230N is a new 12V, 110A unit with an internal regulator and CW rotation. It is listed with a 6 groove pulley, a pulley outside diameter of 63mm, and a Twin Leg alternator mount, so those details should be checked carefully against the vehicle already fitted.

Mounting dimensions are important on this unit: the inside mounting legs measure 82mm, the mount centre to centre is 158mm, the pivot hole diameter is 10mm, and the adjusting hole diameter is M8x1.25. These measurements are the practical checks that help confirm whether the alternator will physically suit the application.

This alternator is supplied as new and carries a one year warranty. It is described as being made from high quality raw materials, corrosion resistant, and fitted with a reduction drive, which are useful points to note when replacing a charging system component in regular road use or harsher conditions.

Application and Buying Notes

The safest way to choose this alternator is to match the part number BXH1230N, then confirm the mounting style and dimensions on the vehicle. The important checks here are the Twin Leg mount, 82mm inside mounting legs, 158mm mount centre to centre, 10mm pivot hole, and M8x1.25 adjusting hole.

Electrical output also matters. This unit is rated at 110A and 12V, with an internal regulator, so it should only be compared with the vehicle’s required charging system specification and the alternator already fitted. Matching the pulley layout is just as important, because this unit uses a 6 groove pulley with a 63mm outside diameter.

The rotation direction is CW, which needs to align with the application. If the existing alternator differs in mount type, pulley section, regulator arrangement, or rotation, do not rely on appearance alone. Use the measured details and the vehicle application list as the final check before ordering.

Because this is a Bosch alternator supplied new, it is intended as a direct replacement where the physical and electrical details match. If you are working from an existing unit, compare the label, connector arrangement, and mounting points against the listed specifications before installation to avoid unnecessary returns or delays.

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 BXH1230N 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.
