Bosch Alternator 12V 70A BXD1306N

The Bosch Alternator BXD1306N is a new 12V, 70A unit with an internal regulator and a 5 groove pulley. It is listed with a single leg alternator mount, a 62mm pulley outside diameter, and a 58mm mount leg thickness, so those dimensions are worth checking against the vehicle before ordering.

This alternator is supplied as a Bosch unit under the rotating electrical product group, and it carries a one year warranty. The unit weight is 4.54kg, which can be useful when comparing against the removed alternator or confirming you are looking at the correct replacement type.

The construction details matter here: Bosch lists non-recycled copper, application-designed regulators, and premium quality bearings. Those are specific component-level features relevant to durability, electrical quality, and service life, but the right physical fit still depends on matching the part number and the mounting and pulley details.

For buyers working through a replacement job, the safest approach is to compare the BXD1306N part number, 12V voltage, 70 amp rating, IR11 pin code, and the pulley and mount measurements before purchase. Those checkpoints help reduce the risk of ordering a visually similar alternator that does not line up correctly on the vehicle.

Application and Buying Notes

Before buying, confirm the removed alternator matches Bosch part number BXD1306N and check that the unit is a 12V, 70A alternator with an internal regulator. These are the main identification points supplied for this listing and they should be matched carefully rather than relying on appearance alone.

Also compare the mounting and pulley details. This alternator uses a single leg mount, a 58mm mount leg thickness, a 5 groove pulley, and a 62mm pulley outside diameter. If any of those dimensions differ on the vehicle, the unit may not install correctly or the belt alignment may not suit the application.

The listed pin code is IR11, which is another useful check when comparing electrical connection style. For electrical components, matching the connector and regulator arrangement is just as important as matching output rating, because the wrong configuration can lead to installation issues.

Bosch describes this as a new unit with an internal regulator and one year warranty. That gives you a clear product baseline, but it does not replace a direct fitment check on the vehicle or a comparison with the old alternator. If there is any uncertainty, confirm the application using the part number and the physical specifications before fitting.

The vehicle fitment preview references Toyota Hiace applications across multiple model years, but the safe buying method remains the same: verify the exact model, year, mount style, pulley layout, and part number against the existing unit. That is especially important with alternators, where small differences in mount leg thickness or pulley section can change compatibility.

If you are replacing a charging system component, it is sensible to inspect the belt condition, mounting points, and electrical connector at the same time. A correct alternator still needs the rest of the charging system to be in sound condition, and confirming those parts before installation helps avoid repeat work.

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 BXD1306N 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.

Bosch Alternator 12V 70A. Part number BXD1306N should be checked first. Listed voltage is 12. Listed output rating is 70. 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 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number BXD1306N, 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 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching Bosch part number BXD1306N, the 12V 70A specification, IR11 pin code, single leg mount, 58mm mount leg thickness, and 5 groove pulley details to the vehicle and the removed unit before ordering.
