Bosch Alternator 12V 108A Twin Leg 6 Groove BXM1348

The Bosch BXM1348 alternator is a new 12V unit rated at 108A, supplied as a single each item for the rotating electrical system. It uses an internal regulator, a twin leg alternator mount, and a 6 groove pulley with a 65mm outside diameter, so matching the mounting style and belt arrangement is an important check before ordering.

This alternator is listed to suit Mitsubishi applications with 6G72 and 6G74 engines. The fitment detail is specific to those engine families, so the part number, engine code, mounting dimensions, and pulley layout should be checked together rather than relying on model name alone.

Bosch identifies this unit with part number BXM1348 and pin code IR49. It is described as a generator-type alternator and is built with non-recycled copper, premium quality bearings, and regulators designed for the vehicle application, which are all useful points when comparing it with the original unit removed from the vehicle.

Application and Buying Notes

Before buying, compare the removed alternator against BXM1348 using the mounting and pulley details: twin leg mount, 56mm inside mounting legs, 170mm mount centre to centre, 10mm pivot hole, and M8 x 1.25 adjusting hole. These dimensions matter as much as the electrical rating because a unit can look similar yet still not line up correctly.

The 12V 108A output is a practical point for charge system matching, but it should be matched to the vehicle’s original requirement rather than assumed from the brand alone. This unit also uses an internal regulator and a 6 groove, 65mm pulley, so belt type and pulley alignment should be confirmed before fitting.

Bosch notes this alternator is made with high quality raw materials, non-recycled copper, and long lasting premium bearings. Those are relevant construction details when you want to compare replacement quality, but the safest purchase check remains the part number, engine code, and physical dimensions on the old unit.

A V-belt or V-ribbed belt is listed as a recommended additional repair item. If the belt shows wear, glazing, cracking, or contamination, replacing it at the same time can help avoid installing a new alternator against an already compromised drive belt.

If the vehicle has been modified, or if the original alternator has been replaced before, confirm the pulley section, mount style, and regulator type carefully. A generator-type alternator with the correct amperage still needs the correct mechanical and electrical match to suit the application properly.

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 BXM1348 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Inside Mounting Legs 56mm, Pivot Hole Diameter 10, Pulley Outside Diameter 65mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 170mm, Alternator Type For generator.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. BXM1348, Brand BOSCH, Description Bosch Alternator 12V 108A, Adjusting Hole Diameter M8 x 1.25, Pin Code IR49, Power Rating (Amp) 108, Pulley Section 6 Groove, Suits Unit Make Bosch.

Bosch Alternator 12V 108A. Part number BXM1348 should be checked first. Listed voltage is 12. Listed output rating is 108. 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXM1348, 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 108 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using Bosch part number BXM1348, the listed Mitsubishi 6G72 or 6G74 engine application, and the physical measurements of the removed alternator before purchase.
